    PETITION FOR REVIEW OF AN ORDER OF

    February 28, 2022
    LYNCH, Circuit Judge.         Petitioner Carlos Monteiro Silva
    seeks review of a final order of removal issued by the Board of
    Immigration Appeals ("BIA") in May 2020. The BIA dismissed Silva's
    appeal of a decision by the immigration judge ("IJ") holding that
    Silva was removeable under the Immigration and Nationality Act
    ("INA"), 
    8 U.S.C. § 1227
    (a)(2)(A)(iii), for having committed an
    "aggravated felony" as defined under 
    8 U.S.C. § 1101
    (a)(43).                      The
    IJ determined and the BIA affirmed that Silva's Massachusetts state
    conviction for accessory after the fact to the crime of murder was
    categorically an aggravated felony for purposes of the INA because
    it met the definition of "an offense relating to obstruction of
    justice."     
    Id.
     § 1101(a)(43)(S).        The IJ and BIA held that Silva
    was ineligible for withholding of removal because he had committed
    a   particularly    serious   crime    and   had      not   met    his   burden   to
    establish that he was eligible for asylum or relief under the
    Convention Against Torture ("CAT").
    Silva argues that the IJ and the BIA erred by applying
    the categorical approach to determine that his state conviction
    for   accessory     after   the    fact    was    "an   offense      relating     to
    obstruction    of    justice."       Id.         He   argues      that   the   BIA's
    interpretation of "an offense relating to obstruction of justice"
    as including offenses where an investigation or proceeding is only
    "reasonably foreseeable"          is an unreasonable interpretation of
    § 1101(a)(43)(S) and that the INA unambiguously requires that an
    - 2 -
    obstruction of justice offense have some nexus to a pending or
    ongoing   investigation        or   judicial    proceeding,      which   the
    Massachusetts accessory-after-the-fact statute does not require.
    For this and other reasons, Silva argues that deference under
    Chevron, U.S.A., Inc. v. Natural Resources Defense Council, Inc.,
    
    467 U.S. 837
     (1984), does not apply to the BIA's interpretation
    and that Silva's conviction for accessory after the fact is not
    categorically an obstruction of justice offense triggering the
    INA's aggravated felony grounds for removal.1
    We make two holdings, each of which provides a basis for
    denying the petition.          First, we follow the mode of analysis
    employed by the Supreme Court in Esquivel-Quintana v. Sessions,
    
    137 S. Ct. 1562
     (2017), and so apply "the normal tools of statutory
    interpretation,"   
    id. at 1569
    .   We     hold   the   generic   federal
    definition of "an offense relating to obstruction of justice"
    unambiguously does not require a nexus to a pending or ongoing
    investigation or judicial proceeding.             Alternatively, we also
    hold, employing Chevron analysis, that the BIA's interpretation
    must be sustained.       Consonant with these holdings, we conclude
    that the IJ and BIA properly concluded that Silva's Massachusetts
    conviction for accessory after the fact is categorically an offense
    relating to obstruction of justice and so rendered him removable
    1    We acknowledge and thank amici curiae for their brief in
    support of the petitioner.

    as an aggravated felon.    We deny Silva's petition using each mode
    of analysis.
    I.
    A.    Massachusetts State Conviction
    Silva is a native and citizen of Cape Verde who was
    admitted to the United States in 1989 as a lawful permanent
    resident.
    In September 2017, Silva pleaded guilty in Massachusetts
    to accessory after the fact in violation of 
    Mass. Gen. Laws ch. 274, § 4
    .    That statute provides that,
    [w]hoever, after the commission of a felony,
    harbors, conceals, maintains or assists the
    principal felon or accessory before the fact,
    or gives such offender any other aid, knowing
    that he has committed a felony or has been
    accessory thereto before the fact, with intent
    that he shall avoid or escape detention,
    arrest, trial or punishment, shall be an
    accessory after the fact.
    
    Id.
       The offense to which Silva pleaded guilty occurred in 2003.
    The September 2003 indictment that described the offense stated
    that three men, not including Silva, "on April 28, 2003, did
    assault and beat [the victim] with intent to murder him and by
    such assault did kill and murder [the victim]."    As to Silva, the
    indictment charged that he, "well knowing . . .     the [three men]
    to have committed the felony . . . [,] did harbor, conceal,
    maintain, assist or give any other aid to the said [three men],
    with intent that the said [three men] should avoid and escape
    - 4 -
    detention, arrest, trial and punishment" by driving those three
    men away from the scene of the murder.2          Silva was sentenced to
    between four and five years in Massachusetts state prison.
    B.   Removal Proceedings and BIA Decision
    In   January   2018,   the     U.S.   Department   of   Homeland
    Security ("DHS") initiated removal proceedings against Silva.3          In
    March 2019, DHS amended the charges of removal against Silva.
    Those amended charges stated that Silva was removable for, among
    other things, having been convicted of an aggravated felony in the
    form of "an offense relating to obstruction of justice . . . for
    which the term of imprisonment was at least one year."              See 
    8 U.S.C. §§ 1227
    (a)(2)(A)(iii), 1101(a)(43)(S).4        Silva objected to
    those amended charges of removal.
    2    Silva's plea leaves no doubt that he intended to obstruct
    a reasonably foreseeable investigation.        To the extent our
    dissenting colleague argues to the contrary, the state court
    conviction precludes such a holding.
    3    This case has a long procedural history involving an
    initial termination of removal proceedings against Silva and a
    reinstatement of proceedings against him on different charges of
    removal. We describe only those later proceedings which led to
    this appeal.
    4    The amended charges also stated that Silva was
    removeable for having been convicted of two or more crimes
    involving moral turpitude. See 
    8 U.S.C. § 1227
    (a)(2)(A)(ii). That
    charge of removal was based on Silva's Massachusetts accessory-
    after-the-fact conviction and an earlier Massachusetts state
    conviction for receiving stolen property in violation of 
    Mass. Gen. Laws ch. 266, § 60
    . The IJ and the BIA ultimately did not
    rely on this alternative ground for removal because of updated
    criminal documents filed with the IJ by Silva reflecting that a
    Massachusetts state court had allowed his motion to vacate his
    - 5 -
    In a written decision in May 2019, the IJ held that
    Silva's    Massachusetts   accessory-after-the-fact   conviction   was
    categorically an offense relating to obstruction of justice under
    the INA and so was a proper ground for removal as an aggravated
    felony.5     The IJ relied on the BIA's decision in        Matter of
    Valenzuela Gallardo, 
    27 I. & N. Dec. 449
    , 452-60 (B.I.A. 2018),
    underlying removal order vacated in Valenzuela-Gallardo v. Barr,
    
    968 F.3d 1053
     (9th Cir. 2020).6
    plea for several prior convictions, including his conviction for
    receiving stolen property. They declined to decide what effect,
    if any, that state court decision would have on Silva's removal
    proceedings. The only issue for our review is the IJ's and the
    BIA's determination about the aggravated felony charge for
    removal.
    5    "[T]o determine whether an alien's conviction qualifies
    as an aggravated felony under th[e INA], [courts and the agency]
    'employ a categorical approach by looking to the statute . . . of
    conviction, rather than to the specific facts underlying the
    crime.'" Esquivel-Quintana, 
    137 S. Ct. at 1567-68
     (ellipsis in
    original) (quoting Kawashima v. Holder, 
    565 U.S. 478
    , 483 (2012));
    see also De Lima v. Sessions, 
    867 F.3d 260
    , 262-63 (1st Cir. 2017).
    "Under that approach, we ask whether 'the state statute defining
    the crime of conviction categorically fits within the generic
    federal definition of a corresponding aggravated felony.'"

    , 190
    (2013)); see also De Lima, 867 F.3d at 262-63. "[W]e presume that
    the          state         conviction          'rested         upon
    . . . the least of th[e] acts' criminalized by the statute, and
    then we determine whether that conduct would fall within the
    [generic] federal definition of the crime."      Esquivel-Quintana,
    
    137 S. Ct. at 1568

    559 U.S. 133
    , 137 (2010)); see
    also De Lima, 867 F.3d at 263.
    6    Valenzuela Gallardo, applying the categorical approach,
    held that the generic definition of obstruction of justice includes

    Silva then filed applications for asylum, withholding of
    removal, and protection under the CAT.              In a written decision in
    December 2019, the IJ denied all three forms of relief from
    removal.      The     IJ   concluded     that    Silva's    aggravated    felony
    conviction for accessory after the fact rendered him statutorily
    ineligible     for     asylum,     see    
    8 U.S.C. § 1158
    (b)(2)(A)(ii),
    (b)(2)(B)(i), and that the conviction was a "particularly serious
    crime" which barred his application for withholding of removal,
    see 
    id.
     § 1231(b)(3)(B)(ii).         The IJ also concluded that Silva did
    not provide sufficient evidence to support his application for CAT
    protection.
    Silva appealed to the BIA.            In May 2020, the BIA denied
    that appeal.      The BIA, referencing Matter of Valenzuela Gallardo,
    adopted and affirmed the IJ's decision, holding that Silva's
    Massachusetts          accessory-after-the-fact              conviction      was
    categorically an aggravated felony relating to obstruction of
    justice.     The BIA also held that the IJ did not clearly err in
    finding    that      Silva's     Massachusetts      accessory-after-the-fact
    crimes involving: "(1) an affirmative and intentional attempt
    (2) that is motivated by a specific intent (3) to interfere with
    an investigation or proceeding that is ongoing, pending, or
    'reasonably foreseeable by the defendant.'" 27 I. & N. Dec. at
    456 (emphasis added) (quoting Marinello v. United States, 
    138 S. Ct. 1101
    , 1110 (2018)) (citing United States v. Aguilar, 
    515 U.S. 593
    , 599 (1995)).   Applying that generic federal definition of
    obstruction of justice, the IJ concluded that the elements of
    Silva's Massachusetts accessory-after-the-fact conviction were a
    categorical match.
    - 7 -
    conviction    was    a   particularly     serious      crime    for   purposes     of
    withholding of removal, and affirmed the denial of all forms of
    relief.
    This timely petition for review followed.
    II.
    Silva   first     argues    that    the   Court     should     give   no
    deference to the BIA's interpretation in Matter of Valenzuela
    Gallardo of "an offense relating to obstruction of justice" for
    various reasons.         He also argues that, even if his Massachusetts
    accessory-after-the-fact         conviction      is    an      aggravated     felony
    relating to obstruction of justice, the BIA erred in determining
    that the conviction is a "particularly serious crime" for purposes
    of barring him from withholding of removal.7
    Where, as here, "the BIA adopts and affirms an IJ's
    decision, we review the IJ's decision 'to the extent of the
    adoption, and the BIA's decision as to [any] additional ground.'"
    Sunoto v. Gonzales, 
    504 F.3d 56
    , 59-60 (1st Cir. 2007) (alteration
    in original) (quoting Berrio-Barrera v. Gonzales, 
    460 F.3d 163
    ,
    167   (1st   Cir.    2006)).      We    review    de   novo     the   BIA's   legal
    7   Silva   does   not  challenge   the   IJ's   and   BIA's
    determination that his conviction for accessory after the fact, if
    found to be an aggravated felony, would render him statutorily
    ineligible for asylum. Nor does he challenge the IJ's and BIA's
    denial of his application for deferral of removal under the CAT.
    Any challenge to those two determinations has been waived. See

    conclusions,        including      its    determination      that     Silva's
    Massachusetts accessory-after-the-fact conviction is an aggravated
    felony.     See Lecky v. Holder, 
    723 F.3d 1
    , 4 (1st Cir. 2013).              We
    review the BIA's factual findings under a deferential standard,
    upholding them "as long as they are 'supported by reasonable,
    substantial, and probative evidence on the record considered as a
    whole.'"    Sanabria Morales v. Barr, 
    967 F.3d 15
    , 19 (1st Cir. 2020)
    (quoting Thapaliya v. Holder, 
    750 F.3d 56
    , 59 (1st Cir. 2014)).
    A.   Applying the Tools of Statutory Interpretation as Applied by
    the Supreme Court in Esquivel-Quintana, the Conviction for
    Accessory After the Fact Is an Aggravated Felony "Relating to
    Obstruction of Justice" Under the INA
    We turn first to Silva's argument that his Massachusetts
    accessory-after-the-fact        conviction    is   not   categorically      "an
    offense relating to obstruction of justice" because, he alleges,
    it does not require a nexus to a pending or ongoing investigation
    or judicial proceeding.         In Esquivel-Quintana, the Supreme Court
    addressed    a   similar   issue    of   whether   the   petitioner's    state
    conviction    for    unlawful   sexual    intercourse    with   a   minor   was
    categorically an offense for "sexual abuse of a minor" under 
    8 U.S.C. § 1101
    (a)(43)(A). 
    137 S. Ct. at 1567
    . Applying "the normal
    tools of statutory interpretation," 
    id. at 1569
    , the Court held
    that "in the context of statutory rape offenses that criminalize
    sexual intercourse based solely on the age of the participants,
    the generic federal definition of sexual abuse of a minor requires
    - 9 -
    that the victim be younger than 16," 
    id. at 1568
    .    It held that
    "[b]ecause the California statute at issue in this case does not
    categorically fall within that definition, a conviction pursuant
    to it is not an aggravated felony under § 1101(a)(43)(A)."     Id.8
    The Court determined the meaning of the statutory definition based
    on the text, the structure of the statute and closely related
    federal statutes, the consensus of state criminal statutes, and
    definitions from other sources, like the Model Penal Code.   Id. at
    1569-72.   Because it determined the unambiguous meaning of the
    statute, the Court held it was unnecessary to consider the Chevron
    and rule of lenity issues.   Id. at 1572.
    We initially, as we said, follow the same analytical
    path as the Supreme Court in Esquivel-Quintana and consider the
    same factors to determine the generic federal definition of "an
    offense relating to obstruction of justice."
    8    In Esquivel-Quintana, the petitioner had been convicted
    under a California statute criminalizing "unlawful sexual
    intercourse with a minor who is more than three years younger than
    the perpetrator" in which the statute defined "minor" as "a person
    under the age of 18 years." 
    137 S. Ct. at 1567
     (quoting 
    Cal. Penal Code § 261.5
    (a), (c)). The petitioner was convicted under that
    statute for having had "consensual sexual intercourse . . . [with]
    a 17-year-old" when he was 21.

    1.     The Text of the Statute as a Whole Shows That the
    Generic Federal Definition of "An Offense Relating
    to Obstruction of Justice" Must Be Construed to
    Include Accessory After the Fact
    We begin with the text of the INA.   See 
    id. at 1568-69
    ;
    United States v. De la Cruz, 
    998 F.3d 508
    , 513 (1st Cir. 2021).
    "[W]e accord the statutory text its ordinary meaning by reference
    to the specific context in which that language is used, and the
    broader context of the statute as a whole."    De la Cruz, 998 F.3d
    at 513 (internal quotation marks omitted) (quoting Recovery Grp.,
    Inc. v. Comm'r, 
    652 F.3d 122
    , 125 (1st Cir. 2011)).    When resolving
    a dispute over the meaning of a statute, we "normally seek[] to
    afford the law's terms their ordinary meaning at the time Congress
    adopted them."   Id. at 515 (quoting Niz-Chavez v. Garland, 
    141 S. Ct. 1474
    , 1480 (2021)); see also Esquivel-Quintana, 
    137 S. Ct. at 1569-72
     (interpreting 
    8 U.S.C. § 1101
    (a)(43)(A) according to what
    its ordinary meaning was in 1996 when Congress added that provision
    to the INA).
    a.   The Text of § 1101(a)(43)(S) Supports That
    Accessory After the Fact Is "An Offense
    Relating to Obstruction of Justice"
    Section 1101(a)(43)(S), which provides that "an offense
    relating to obstruction of justice" is an aggravated felony, was
    added to the INA in 1996.    See Antiterrorism and Effective Death
    Penalty Act of 1996, Pub. L. No. 104-132, § 440(e)(8), 
    110 Stat. 1214
    ,   1278;     Illegal   Immigration   Reform      and   Immigrant
    - 11 -
    Responsibility Act of 1996, Pub. L. No. 104-208, § 321(a)(11), 
    110 Stat. 3009
    , 3009-628.        The INA does not define "obstruction of
    justice."    So we turn to reliable contemporaneous dictionaries to
    determine that term's ordinary meaning.               See Esquivel-Quintana,
    
    137 S. Ct. at 1569-70
    ; De la Cruz, 998 F.3d at 515.
    Black's Law Dictionary defined "obstructing justice" as
    "[i]mpeding or obstructing those who seek justice in a court, or
    those who have duties or powers of administering justice therein,"
    "attempt[ing] to prevent, or . . . prevent[ing], the execution of
    lawful process," or "obstructing the administration of justice in
    any way -- as by hindering witnesses from appearing, assaulting
    process servers, influencing jurors, obstructing court orders or
    criminal    investigations."       Obstructing        Justice,     Black's     Law
    Dictionary 1077 (6th ed. 1990).           Another dictionary at that time
    defined "obstruction of justice" as "the crime or act of willfully
    interfering    with   the     process     of    justice   and     law   esp.    by
    influencing,      threatening,    harming,       or   impeding     a    witness,
    potential witness, juror, or judicial officer or legal officer or
    by   furnishing    false    information    in    or   otherwise    impeding    an
    investigation or legal process."          Obstruction of Justice, Merriam-
    Webster's Dictionary of Law 337 (1996).
    Indeed, Bryan Garner, a noted legal commentator often
    cited by the Supreme Court, see, e.g., Esquivel-Quintana, 
    137 S. Ct. at 1569
    ; Van Buren v. United States, 
    141 S. Ct. 1648
    , 1657
    - 12 -
    (2021); Bostock v. Clayton Cnty., 
    140 S. Ct. 1731
    , 1749 (2020);
    Lockhart v. United States, 
    577 U.S. 347
    , 351 (2016), defined
    "obstruction     of     justice"          as   "interference     with     the       orderly
    administration of law" and stated that it was "a broad phrase that
    captures every willful act of corruption, intimidation, or force
    that tends somehow to impair the machinery of the civil or criminal
    law," Obstruction of Justice, B. Garner, A Dictionary of Modern
    Legal   Usage    611    (2d     ed.       1995).      These   definitions       did      not
    explicitly require that the obstructive conduct be committed in
    relation    to   a     pending       or    ongoing    investigation       or    judicial
    proceeding.      Acting as an accessory to a crime after the fact by
    providing some sort of aid to the principal with the intent that
    the principal evade capture, trial, or punishment, even if there
    is not then a pending or ongoing investigation or proceeding,
    certainly    fits      within    these         definitions     of   "obstruction         of
    justice."
    Furthermore,         the       relevant     statutory       term        to   be
    interpreted is not just "obstruction of justice"; rather, it is
    "an   offense    relating       to    obstruction       of    justice."         
    8 U.S.C. § 1101
    (a)(43)(S) (emphasis added).                   The Supreme Court has stated
    in other contexts that the ordinary meaning of the phrase "relating
    to" is "a broad one," holding that it normally means "connection
    with or reference to" something else.                     Morales v. Trans World
    - 13 -
    Airlines, Inc., 
    504 U.S. 374
    , 383-84 (1992).9   The generic federal
    definition of § 1101(a)(43)(S) must necessarily encompass more
    than the definition of "obstruction of justice" itself, including
    offenses connected with or in reference to that concept.       Indeed,
    we "must give effect, if possible, to every clause and word of a
    statute."   Loughrin v. United States, 
    573 U.S. 351
    , 358 (2014)
    (quoting Williams v. Taylor, 
    529 U.S. 362
    , 404 (2000)).       To limit
    the scope of § 1101(a)(43)(S) to only the narrowest possible
    reading of obstruction of justice would violate that core tenet of
    statutory   interpretation.   Accordingly,   even   if   we   read   the
    dictionary detentions more narrowly, we would still conclude that
    Congress intended to cover offenses like Massachusetts accessory-
    after-the-fact.
    9    Silva relies on the Supreme Court's decision in Mellouli
    v. Lynch, 
    575 U.S. 798
     (2015), for the proposition that the
    "relating to" language in § 1101(a)(43)(S) must be given a more
    restrictive reading.    Mellouli is distinguishable.   There, the
    Supreme Court concluded that the "relating to" language in a
    different provision of the INA had to be given a narrower reading
    within the context of the statute because that provision included
    a cross-reference to another specific statute further defining the
    statute of conviction for purposes of removal. See id. at 801-
    02, 808-12, 808 n.9. Here, there is no cross-reference to another
    statute which defines "obstruction of justice" or requires a nexus
    to a pending or ongoing investigation or judicial proceeding.
    - 14 -
    b.       The   Text  and   Structure  of  Surrounding
    Provisions of the INA Support That Accessory
    After the Fact Is "An Offense Relating to
    Obstruction of Justice"
    In addition to the text of the specific provision at
    issue, we also consider the text and structure of the INA as a
    whole.   See Esquivel-Quintana, 
    137 S. Ct. at 1571
     (considering the
    INA's disparate use of cross-references to other statutes in
    interpreting a particular provision).       Most of the offenses listed
    as   "aggravated     felon[ies]"    under   § 1101(a)(43)    specifically
    include cross-references to other federal statutes which define
    those offenses, while no such cross-reference is included to define
    "an offense relating to obstruction of justice."       Compare 
    8 U.S.C. § 1101
    (a)(43)(B)-(F), (H)-(J), (K)(ii)-(iii), (L), (M)(ii), (N)-
    (P) (all containing cross-references to other statutes), with 
    id.
    § 1101(a)(43)(S) (containing none). See also id. § 1101(a)(43)(A),
    (G), (K)(i), (M)(i), (Q)-(R), (T) (also containing no cross-
    references to other statutes).          Moreover, § 1101(a)(43)(S) is
    among only a few of the aggravated felonies under the INA in which
    Congress deliberately used the expansive qualifier "relating to"
    to   describe      the    aggravated   felony.     Compare     
    8 U.S.C. § 1101
    (a)(43)(B)-(F), (H)-(J), (K)(ii)-(iii), (L), (M)(ii), (N)-
    (P) (all using instead something like "defined in" or "described
    in" followed by a cross-reference to another statute defining the
    offense),     with       
    id.
       § 1101(a)(43)(S).      See     also      id.
    - 15 -
    § 1101(a)(43)(K)(i), (Q)-(R), (T) (using "relates to" or "relating
    to" without a cross-reference to another statute).
    Congress easily could have included cross-references in
    § 1101(a)(43)(S) to other statutes to define "an offense relating
    to obstruction of justice," but it chose not to do so.               This shows
    that   Congress   did       not   intend    for   "an   offense    relating   to
    obstruction of justice" to be read restrictively to apply only to
    offenses    defined    by    specific      federal   obstruction    of   justice
    statutes.    See Russello v. United States, 
    464 U.S. 16
    , 23 (1983)
    ("[W]here Congress includes particular language in one section of
    a statute but omits it in another section of the same Act, it is
    generally presumed that Congress acts intentionally and purposely
    in the disparate inclusion or exclusion." (alteration in original)
    (quoting United States v. Wong Kim Bo, 
    472 F.2d 720

    1972))); De la Cruz, 998 F.3d at 517-18.
    2.    The Statute's Relationship to Other Federal
    Statutes Confirms That Accessory After the Fact Is
    "An Offense Relating to Obstruction of Justice"
    In addition to the text of § 1101(a)(43)(S) and the other
    text of the INA, we consider "closely related federal statute[s]"
    in determining the generic federal definition of an aggravated
    felony offense.       Esquivel-Quintana, 
    137 S. Ct. at 1570-71

    a.   The Federal Accessory-After-The-Fact Statute
    and the Federal Bribery Statute Support That
    the Generic Federal Definition Does Not
    Require a Nexus to a Pending or Ongoing
    Investigation or Judicial Proceeding
    The federal accessory-after-the-fact statute, 
    18 U.S.C. § 3
    , is relevant to determining the generic federal definition of
    "an offense relating to obstruction of justice."               That statute
    provides that "[w]hoever, knowing that an offense against the
    United States has been committed, receives, relieves, comforts or
    assists    the     offender   in   order    to   hinder   or   prevent   his
    apprehension, trial or punishment, is an accessory after the fact."
    
    Id.
        "[H]inder[ing] or prevent[ing]" is a type of obstructive
    conduct and "apprehension, trial or punishment" are all different
    stages in the process of "justice."              In that way, the federal
    accessory-after-the-fact       statute     relates   to   "obstruction    of
    justice."10      That statute does not require a nexus to a pending or
    ongoing investigation or judicial proceeding and reaches conduct
    preceding an investigation or proceeding. See, e.g., United States
    v. Neal, 
    36 F.3d 1190
    , 1195, 1211 (1st Cir. 1994) (affirming the
    10  The   Massachusetts   accessory-after-the-fact   statute
    prohibits "harbor[ing], conceal[ing], maintain[ing] or assist[ing]
    the principal felon or accessory before the fact, or giv[ing] such
    offender any other aid, knowing that he has committed a felony or
    has been accessory thereto before the fact, with intent that he
    shall avoid or escape detention, arrest, trial or punishment."
    
    Mass. Gen. Laws ch. 274, § 4
    . That statute covers substantially
    the same conduct as that proscribed by the federal accessory-
    after-the-fact statute.
    - 17 -
    defendant's conviction for accessory after the fact where he
    provided aid to his co-defendants immediately after they robbed a
    bank and helped them to escape apprehension).
    This understanding of the federal accessory-after-the-
    fact statute as relating to obstruction of justice is bolstered by
    case law from the federal circuit courts of appeal before 1996.
    See United States v. Brown, 
    33 F.3d 1002
    , 1004 (8th Cir. 1994)
    (stating that "[t]he gist of being an accessory after the fact
    lies essentially in obstructing justice by rendering assistance to
    hinder or prevent the arrest of the offender after he [or she] has
    committed the crime" (alteration in original) (emphasis added)
    (quoting United States v. Barlow, 
    470 F.2d 1245
    , 1252-53 (D.C.
    Cir. 1972))); United States v. Huppert, 
    917 F.2d 507
    , 510 (11th
    Cir. 1990) (same), superseded by statute in other part, U.S. Sent'g
    Guidelines Manual § 2J1.2(c)(1), cmt. (U.S. Sent'g Comm'n 1991);
    United States v. Balano, 
    618 F.2d 624
    , 631 (10th Cir. 1979) (same),
    abrogated in other part by Richardson v. United States, 
    468 U.S. 317
     (1984); United States v. Willis, 
    559 F.2d 443
    , 444 (5th Cir.
    1977) (same); Gov't of V.I. v. Aquino, 
    378 F.2d 540
    , 553 & n.19
    (3d Cir. 1967) (same); see also Pugin v. Garland, 
    19 F. 4th 437
    ,
    447 n.8 (4th Cir. 2021) (collecting cases).             This consistent
    interpretation of the federal accessory-after-the-fact statute
    when   §   1101(a)(43)(S)   was   enacted   supports   interpreting   "an
    offense relating to obstruction of justice" to include accessory
    - 18 -
    after the fact.        See Guerrero-Lasprilla v. Barr, 
    140 S. Ct. 1062
    ,
    1072 (2020) ("We normally assume that Congress is 'aware of
    relevant    judicial     precedent'     when   it   enacts     a    new   statute."
    (quoting Merck & Co. v. Reynolds, 
    559 U.S. 633
    , 648 (2010))).
    Another     federal   statute      we   consider       is   the   statute
    related to bribery of a witness.11              See 
    18 U.S.C. § 201
    .             The
    federal witness bribery statute includes the giving or offering of
    bribes to witnesses who give testimony at a hearing before a
    congressional committee.          
    Id.
     § 201(b)(3), (c)(2).              The witness
    bribery statute also supports our reading of § 1101(a)(43)(S) as
    not requiring a nexus to a pending or ongoing investigation or
    judicial proceeding.
    b.     Several Obstruction of Justice Offenses Under
    18 U.S.C. Chapter 73 Do Not Require a Nexus to
    a Pending or Ongoing Investigation or Judicial
    Proceeding
    Silva argues that we should look exclusively to Chapter
    73 of Title 18 of the U.S. Code, which is titled "Obstruction of
    Justice,"    to   determine       the   generic      federal        definition    of
    "obstruction of justice."          He asserts that Chapter 73 cannot be
    11   Amici argue that, because the phrase "obstruction of
    justice" appears next to "perjury or subornation of perjury" and
    "bribery of a witness" in § 1101(a)(43)(S), all three must be read
    to share the common characteristic of a nexus to a pending or
    ongoing investigation or judicial proceeding.     We do not agree
    that the federal witness bribery statute requires a nexus to a
    pending or ongoing judicial proceeding and so this cannot be a
    common characteristic to all three offenses listed.
    - 19 -
    reviewed for its components but must be read as a whole to require
    a   nexus   to   a   pending    or    ongoing    investigation   or     judicial
    proceeding.      We disagree.        Chapter 73 contains many offenses and
    cannot be read as a whole.
    Section    1512,    which    is     titled   "[t]ampering    with   a
    witness, victim, or an informant," specifically provided in 1996
    that "[f]or the purposes of this section . . . an official
    proceeding need not be pending or about to be instituted at the
    time of the offense."12        
    18 U.S.C. § 1512
    (e)(1) (1996); see Pugin,
    19 F.4th at 445.13      Nor does the text of § 1511, which prohibited
    the "[o]bstruction of State or local law enforcement,"14 require
    12  The Ninth Circuit reads § 1512 as "underscor[ing] that
    the common understanding at the time § 1101(a)(43)(S) was enacted
    into law was that an obstruction offense referred only to offenses
    committed while proceedings were ongoing or pending. [For] [i]f
    that were not the case, it would not have been necessary for
    Congress to make clear that § 1512 operates differently than the
    other provisions in Chapter 73." Valenzuela-Gallardo, 968 F.3d at
    1065-66. Not so. A proceeding that is about to be instituted is
    not pending or ongoing, but it could be reasonably foreseeable.
    The "about to be instituted" language thus suggests that Congress
    believed that obstruction of justice could encompass the
    frustration of official proceedings that are not yet in place.
    13   In Pugin, the Fourth Circuit relied on Chevron deference
    to conclude that Virginia accessory after the fact is "an offense
    relating   to   obstruction   of    justice"   for   purposes   of
    § 1101(a)(43)(S). 19 F.4th at 439. We find much of the Fourth
    Circuit's analysis persuasive.
    14   In any event, as to those Chapter 73 offenses which do
    require a nexus to a pending or ongoing investigation or judicial
    proceeding, it is clear that Congress did not intend for those
    specific offenses to define "an offense relating to obstruction of
    justice" for purposes of § 1101(a)(43)(S). For that same reason,
    we reject Silva's argument that we cannot consider the federal
    - 20 -
    that an investigation or judicial proceeding be pending or ongoing.
    Id. § 1511 (1996).
    Indeed, as the Fourth Circuit recently held, obstruction
    of justice for the purposes of § 1101(a)(43) is not limited to
    "the narrow confines of Chapter 73."         Pugin, 19 F.4th at 445.
    c.    Congress Intended Obstruction of Justice to be
    Read More Broadly Than Other Aggravated
    Felonies
    Congress specifically included cross-references to other
    federal   statutes   in   defining   other    offenses   that   constitute
    aggravated felonies under § 1101(a)(43), but it included no cross-
    reference to Chapter 73 or any particular offense under that
    chapter to define "an offense relating to obstruction of justice."
    Congress also deliberately used the qualifier "relating to" in
    conjunction with "obstruction of justice" in § 1101(a)(43)(S),
    even though it did not do so for most of the other offenses listed
    as aggravated felonies under the INA.          This shows that Congress
    clearly did not intend for "an offense relating to obstruction of
    justice" to be restricted only to the obstruction of justice
    offenses listed under Chapter 73, let alone to any particular
    Chapter 73 offense that requires a nexus to a pending or ongoing
    accessory-after-the-fact statute, 
    18 U.S.C. § 3
    , because it is not
    located under Chapter 73.

    investigation or judicial proceeding.15    See Pugin, 19 F.4th at
    448; Russello, 
    464 U.S. at 23
    ; De la Cruz, 998 F.3d at 517-18; see
    also Esquivel-Quintana, 
    137 S. Ct. at 1571
     (noting that "many other
    aggravated felonies in the INA are defined by cross-reference to
    other provisions of the United States Code," and relying on a
    related federal statute "for evidence of the meaning of [the
    aggravated felony offense], but not as providing the complete or
    exclusive definition" where there was no such cross-reference);
    cf. Mellouli, 575 U.S. at 808 n.9, 811 n.11 (noting the importance
    of the relationship between the language "relating to" in the
    15   For this reason, the Supreme Court's decision in United
    States v. Aguilar, 
    515 U.S. 593
     (1995), also does not support
    Silva's reading of § 1101(a)(43)(S).      Aguilar held that, for
    purposes of the "catchall" provision of 
    18 U.S.C. § 1503
    , which
    criminalizes "[i]nfluencing or injuring [an] officer or [a] juror
    generally," "[t]he action taken by the accused must be with an
    intent to influence judicial or grand jury proceedings; it is not
    enough that there be an intent to influence some ancillary
    proceeding, such as an investigation independent of the court's or
    grand jury's authority." 
    515 U.S. at 599
     (emphasis added); see
    also 
    id. at 600-01
     (holding that making false statements to an
    investigating officer "who might or might not testify before a
    grand jury" was insufficient to violate the catchall provision of
    § 1503); 
    18 U.S.C. § 1503
    (a) (1996) (prohibiting "corruptly or by
    threats or force, or by any threatening letter or communication,
    influenc[ing], obstruct[ing], or imped[ing], or endeavor[ing] to
    influence, obstruct, or impede, the due administration of
    justice").
    That decision addressed only the specific statute at issue
    and did not establish the requirements of "obstruction of justice"
    more generally.   Nor does § 1101(a)(43)(S) incorporate § 1503's
    particular definition of "obstruction of justice" through cross-
    reference. Even Silva acknowledges that a nexus to a pending or
    ongoing investigation would be enough to satisfy his purported
    nexus requirement.

    statute and a specific statutory cross-reference in applying the
    categorical approach).16
    3.   Other Sources of the Statute's Meaning Support That
    Accessory After the Fact Is "An Offense Relating to
    Obstruction of Justice"
    In addition to the text and structure of the statute and
    closely related federal statutes, we also consider other indicia
    identified in Esquivel-Quintana in determining the generic federal
    definition of "an offense relating to obstruction of justice."
    a.   A Consensus of State Obstruction of Justice
    Statutes Confirm That "An Offense Relating to
    Obstruction of Justice" Does Not Require a
    Nexus to a Pending or Ongoing Investigation or
    Judicial Proceeding
    One of those other sources we consider is a consensus of
    "state criminal codes" which "we look to . . . for additional
    evidence about the generic meaning of" an offense.       Esquivel-
    16   Silva relies on the Third Circuit decision in Flores v.
    Attorney General, 
    856 F.3d 280
    , 292-96 (3d Cir. 2017), and the
    Ninth Circuit decision in Valenzuela Gallardo, which held that
    state convictions for accessory after the fact were not offenses
    relating to obstruction of justice because they lacked a nexus
    requirement.    We find neither persuasive.       Both Flores and
    Valenzuela Gallardo relied exclusively on offenses listed under
    Chapter 73 in defining the generic federal definition of §
    1101(a)(43)(S) and discounted or did not consider other evidence
    of the statute's meaning. See Flores, 856 F.3d at 287-96; id. at
    297-301 (Shwartz, J., concurring, in part, and dissenting, in part)
    (disagreeing with the majority that the court was limited to
    consideration of only Chapter 73 offenses to determine the generic
    federal definition of "an offense relating to obstruction of
    justice" and concluding that a South Carolina accessory-after-the-
    fact conviction related to obstruction of justice); Valenzuela

    § 1101(a)(43)(S) was added to the INA, seventeen states used

    And the obstruction of justice statutes in four of these
    latter states proscribed conduct which would have been punishable
    under the federal accessory-after-the-fact statute.        See 
    Colo. Rev. Stat. § 18-8-105
     (1996);

    (A)(1), (3) (1996); 
    Utah Code Ann. § 76-8-306
    (b), (e) (1996).       That the vast majority of
    jurisdictions with obstruction of justice offenses did not limit
    that concept to only offenses with a nexus to a pending or ongoing
    investigation or judicial proceeding further confirms our reading
    of the generic federal definition.      See Esquivel-Quintana, 
    137 S. Ct. at 1571-72
    .
    b.   The Model Penal Code and Federal Sentencing
    Guidelines Further Support That Accessory
    After the Fact Is "An Offense Relating to
    Obstruction of Justice"
    The Model Penal Code and Federal Sentencing Guidelines
    also support that "an offense relating to obstruction of justice"
    includes accessory after the fact.       See 
    id.
     at 1571 (citing the
    Model Penal Code as evidence of the generic meaning of a term in
    the INA).   When § 1101(a)(43)(S) was enacted, the Model Penal Code
    - 25 -
    listed "Hindering Apprehension or Prosecution," which proscribes
    conduct like that proscribed in the federal accessory-after-the-
    fact statute, under the article for "Obstructing Governmental
    Operations; Escapes."     Model Penal Code § 242.3 (Am. L. Inst.
    1985).    In describing the offense of hindering apprehension or
    prosecution of another, the explanatory notes to the Model Penal
    Code states that the "offense covers the common law category of
    accessory after the fact but breaks decisively with the traditional
    concept that the accessory's liability derives from that of his
    principal . . . [and instead provides that the accessory] is
    convicted . . . for an independent offense of obstruction of
    justice."    Id. § 242.1 explanatory note; see also Pugin, 19 F.4th
    at 445.
    The Federal Sentencing Guideline for "Obstruction of
    Justice" in effect in 1996 cross-referenced the guideline for
    "Accessory After the Fact."     See U.S. Sent'g Guidelines Manual
    § 2J1.2(c) (U.S. Sent'g Comm'n 1995).       The commentary to the
    "Obstruction of Justice" guideline stated that "[b]ecause the
    conduct covered by this guideline is frequently part of an effort
    to avoid punishment for an offense that the defendant has committed
    or to assist another person to escape punishment for an offense,
    a cross reference to [the Accessory After the Fact guideline] is
    provided."    Id. § 2J1.2 cmt. background (emphasis added).     The
    commentary and cross-reference are further support that there was
    - 26 -
    an understood connection between accessory after the fact and
    obstruction of justice when § 1101(a)(43)(S) was adopted.
    4.    Even Assuming Arguendo That There Must Be a Nexus
    to an Investigation for the Normal Accessory-After-
    the-Fact Crime, That Nexus Is Satisfied
    Assuming arguendo that § 1101(a)(43)(S) requires any
    nexus to an investigation, whether actually pending or in the
    offing,   the   Massachusetts   accessory-after-the-fact   crime   and
    conviction easily satisfies it.17
    
    Mass. Gen. Laws ch. 274, § 4
     provides:
    [w]hoever, after the commission of a felony,
    harbors, conceals, maintains or assists the
    principal felon or accessory before the fact,
    or gives such offender any other aid, knowing
    that he has committed a felony or has been
    accessory thereto before the fact, with intent
    that he shall avoid or escape detention,
    arrest, trial or punishment, shall be an
    accessory after the fact.
    17   Our dissenting colleague overreads our assumption in
    this section that a nexus is required.    We find in the statutory
    text no requirement for a nexus, see supra Part II.A.1, and so in
    our de novo review under Esquivel-Quintana we do not graft a nexus
    requirement on to the statute. The BIA, however, interpreted the
    statute to mean that an offender must "interfere with an
    investigation or proceeding that is ongoing, pending, or
    'reasonably foreseeable'" Matter of Valenzuela Gallardo, 27 I. &
    N. Dec. at 456 (quoting Marinello, 
    138 S. Ct. at 1110
    ). To the
    extent the statute is ambiguous, the BIA's interpretation of the
    nexus requirement is certainly reasonable and due deference. See
    infra Part II.B. Our de novo analysis makes clear, though, that
    the BIA could also dispense with its nexus requirement. Either
    construction would "fill the statutory gap in reasonable fashion."
    Negusie v. Holder, 
    555 U.S. 511
    , 523 (2009)
    - 27 -
    To be convicted under that statute, the accessory must act with
    specific intent to enable a felon to "avoid or escape detention,
    arrest, trial, or punishment."   Absent an investigation, there can
    be no prosecution and no detention, arrest, trial, or punishment
    to avoid or escape.
    In determining the least culpable conduct that violates
    the statue, Moncrieffe v. Holder directs us to "focus on the
    minimum conduct criminalized by the state statue," rather than
    "apply 'legal imagination' to the state offense."    
    569 U.S. 184
    ,
    191 (2013).    Unlike the dissent, we look not to hypothetical
    conduct but to the "the least serious conduct for which there is
    a 'realistic probability' of charge and conviction." United States
    v. Starks, 
    861 F.3d 306
    , 315 (1st Cir. 2017) (quoting id.).
    Looking at the mine run of prosecutions, we see none for aiding
    and abetting less serious felonies.    When we look at the seventy
    Massachusetts state court opinions on Westlaw that cite § 4, the
    overwhelming majority are convictions for accessory after the fact
    to homicide.   Those that do not involve homicide, involve other
    serious offenses: armed robbery, e.g., Commonwealth v. Ayoub, 
    32 N.E.3d 369
     (Mass. App. Ct. 2015) (table); assault with a dangerous
    weapon, e.g., Commonwealth v. Nick N., 
    952 N.E.2d 991
     (Mass. App.
    Ct. 2011) (table); arson, Commonwealth v. Sokorelis, 
    150 N.E. 197
    (Mass. 1926); kidnapping, Commonwealth v. Eagan, 
    259 N.E.2d 548
    (Mass. 1970); escape from prison, e.g., Commonwealth v. Holiday,
    - 28 -
    
    206 N.E.2d 691
     (Mass. 1965); extortion, Commonwealth v. Cachopa,
    
    18 N.E.3d 1137
     (Mass. App. Ct. 2014) (table); dealing cocaine,
    Commonwealth v. St. Pierre, 
    786 N.E.2d 438
     (Mass. App. Ct. 2003)
    (table); and larceny, e.g., Commonwealth v. Kudrya, 
    843 N.E.2d 1117
     (Mass. App. Ct. 2006) (table).    Indeed, the serious nature of
    the crimes actually prosecuted under § 4 supports our holding that
    the least culpable conduct likely to be charged under the provision
    includes a fair probability of criminal investigation.18   In fact,
    the serious crimes for which accessory-after-the-fact prosecutions
    have been brought by their nature would inform any person acting
    as an accessory that there will be an investigation resulting in
    "escape detention, arrest, trial or punishment."19     Further, the
    18   Our dissenting colleague relies on Marinello v. United
    States, 
    138 S. Ct. 1101
     (2018), to support his contention that a
    felonious money launderer in Massachusetts must have more than
    mere awareness that the authorities might catch on to his illegal
    financial scheme. Dissenting Op. at 46-50 (citing Marinello, 
    138 S. Ct. at 1110
    ).      In the dissenting opinion's telling, the
    government failed to establish that its investigation of Marinello
    was "reasonably foreseeable," because it could show no more than
    that mere awareness. Id. at 8 (quoting Marinello, 131 S. Ct. at
    1110). But in Marinello, the Court had no opportunity to weigh in
    on   whether   the   government    had   presented    evidence   of
    foreseeability; the trial judge did not instruct the jury on
    foreseeability as Marinello requested, Marinello, 
    138 S. Ct. at 1105
    , and the Court vacated and remanded, 
    id. at 1110
    . Thus, the
    opinion cannot be read -- as our dissenting colleague does -- to
    support a categorical rule for financial criminals.
    19   We note that on the facts here, an investigation to quote
    the dissent and "[t]o use a maritime analogy" is easily thought to
    be "in the offing," Dissenting Op. at 46 (quoting Marinello, 
    138 S. Ct. at 1110
    ). While the dissent seems to treat the offing as
    a term of proximity, it refers, in the maritime sense, to "[t]he
    - 29 -
    statute requires a specific intent to do so, buttressing our
    analysis.
    These offenses are also markedly different from the tax
    fraud scheme in United States v. Marinello, on which our dissenting
    colleague puts so much weight, in another key way.               Persons are
    often able to skirt tax laws and go undetected for some time.
    Indeed, by definition, a person who commits tax evasion attempts
    to   conceal   his   acts   and    evade   detection.   United    States   v.
    Stierhoff, 
    549 F.3d 19
    , 25 (1st Cir. 2008) (elements of tax evasion
    include "an affirmative act of evasion or attempted evasion");
    see, e.g., United States v. Marek, 
    548 F.3d 147
    , 150–51 (1st Cir.
    2008) (defendant falsified invoices); United States v. Lavoie, 
    433 F.3d 95
    ,     98-100   (1st      Cir.   2005)   (defendant   intentionally
    underreported revenue).        An investigation of a tax offense would
    not be in the offing upon the commission of the offense.                   By
    contrast, consider murder, the underlying crime here.              Following
    a homicide, more often than not the murder is reported, or a body
    is found, or a person is reported missing.              A law enforcement
    investigation is reasonably foreseeable.          Also consider robbery or
    part of the sea visible from the shore that is very distant or
    beyond anchoring ground."       Offing, The American Heritage
    Dictionary of the English Language 1223 (5th ed. 2018); accord
    offing, The New Oxford American Dictionary 1181 (2d ed. 2005)
    ("[T]he more distant part of the sea in view."). For this crime
    and for any of the serious crimes that have actually triggered an
    accessory-after-the-fact investigation in Massachusetts, the
    investigation could be spotted on the horizon.
    - 30 -
    extortion,       crimes   which   underlie    other    actual    Massachusetts
    accessory-after-the-fact          prosecutions.       These   crimes   involve
    immediate harm to a victim, unlike with tax crimes, where the
    government must uncover an offense against the fisc.                   In such
    situations, it is more likely that a law enforcement investigation
    is in the offing.
    For the reasons stated above, it is clear that Silva's
    Massachusetts accessory-after-the-fact conviction is an aggravated
    felony under § 1101(a)(43)(S) because it is categorically "an
    offense relating to obstruction of justice."20
    5.      The Dissent Misreads the BIA's Analysis
    There is no basis to conclude that we have adopted a
    much looser nexus requirement than the BIA.                     Our dissenting
    colleague overreads the BIA's analysis in Matter of Valenzuela
    Gallardo to create a far tighter nexus requirement than the agency
    did.
    20 We need not determine the precise boundaries of what
    constitutes "an offense relating to obstruction of justice" under
    § 1101(a)(43)(S). Cf. Esquivel-Quintana, 
    137 S. Ct. at 1572
    . It
    is enough that the various sources show that accessory after the
    fact, as defined under the Massachusetts statute, clearly relates
    to obstruction of justice for purposes of the INA. For that same
    reason, Silva's argument that the statute is void for vagueness is
    also meritless. See United States v. Zhen Zhou Wu, 
    711 F.3d 1
    , 16
    (1st Cir. 2013) ("[W]e consider 'whether a statute is vague as
    applied to the particular facts at issue,' for a defendant 'who
    engages in some conduct that is clearly proscribed cannot complain
    of the vagueness of the law as applied to the conduct of others.'"
    (quoting Holder v. Humanitarian L. Project, 
    561 U.S. 1
    , 18-19
    (2010)) (emphasis in original)).
    - 31 -
    The    BIA   held    that      generic    obstruction    of   justice
    "cover[s] crimes involving (1) an affirmative and intentional
    attempt (2) that is motivated by a specific intent (3) to interfere
    with an investigation or proceeding that is ongoing, pending, or
    'reasonably foreseeable by the defendant.'"             Matter of Valenzuela
    Gallardo, 27 I. & N. Dec. at 456 (quoting Marinello, 
    138 S. Ct. at 1110
    ); see also 
    id.
     at 456 n.9.          The BIA identified three types of
    investigations   covered      by   the   offense:    ongoing,     pending,   and
    reasonably foreseeable.       But our dissenting colleague takes such
    a narrow view of "reasonably foreseeable" that it essentially
    merges into ongoing and pending investigations.            He errs, in part,
    by interpreting the BIA's quotation of the reasonably foreseeable
    language in Marinello to require an identical nexus in both the
    statute at issue there, 
    26 U.S.C. § 7212
    (a), and the statute at
    issue here, § 1101(a)(43)(S). The BIA, however, expressly rejected
    that false equivalence, explaining that "Congress intended section
    101(a)(43)(S) of the Act to apply more broadly than the provisions
    at issue in . . . Marinello."         27 I. & N. Dec. at 454 n.6.21
    21   In our view, our dissenting colleague is also incorrect
    when he argues that Chenery I requires us to interpret Marinello
    identically to the BIA.    Dissenting Op. at 60-62; see SEC v.
    Chenery Corp., 
    318 U.S. 80
    , 95 (1943). Chenery I "merely hold[s]
    that an administrative order cannot be upheld unless the grounds
    upon which the agency acted in exercising its powers were those
    upon which its action can be sustained." 
    318 U.S. at 95
    . To be
    sure we cannot substitute a new rationale when the agency
    "misconceive[s] the law," 
    id.,
     but when the agency clearly states
    - 32 -
    To    confirm   that     the   dissent   misconstrues    the    BIA's
    decision, we need look no further than the BIA implementation of
    Matter of Valenzuela Gallardo.             In Matter of Cordero-Garcia, the
    BIA held that the California offense of dissuading a witness is
    categorically an offense related to obstruction of justice.                 27 I.
    & N. 652, 653-54 (2019) (citing 
    Cal. Penal Code § 136.1
    (b)(1)),
    petition for review filed sub nom. Cordero-Garcia v. Garland, No.
    19-72779 (9th Cir. argued Feb. 11, 2022).              The BIA held that the
    statute's     specific      intent     requirement     implied     that    "    an
    investigation or proceeding would necessarily be either ongoing,
    pending, or reasonably foreseeable."                 
    Id. at 654
    .     "In other
    words," it concluded, "there would be little reason for a person
    to try to prevent or dissuade a victim or witness from reporting
    the   crime      to   appropriate     authorities     unless     there    was   an
    investigation in progress[,] or one was reasonably foreseeable."
    its legal basis for acting, Chenery I does not require that we
    follow the exact same interpretative path in sustaining the
    agency's   actions,  see   H.J.   Friendly,  Chenery   Revisited:
    Reflections on Reversal and Remand of Administrative Orders, 
    1969 Duke L.J. 199
    , 211.      The BIA determined that Massachusetts
    accessory-after-the-fact is categorically an offense related to
    obstruction of justice, that Silva was convicted of that offense,
    and that he was therefore ineligible for withholding of removal.
    We deny Silva's petition on the same grounds. To the extent that
    we read the INA to authorize the BIA to act through a potentially
    different pathway is of no moment.    To hold otherwise would be
    perilous, with the Supreme Court indicating growing disfavor
    towards deference to administrative agencies, see, e.g., Kisor v.
    Wilkie, 
    139 S. Ct. 2400
    , 2424-2425 (Roberts, C.J., concurring);
    
    id. at 2425-2449
     (Gorsuch, J., dissenting).
    - 33 -
    
    Id.
        The BIA's interpretation of that California statute is on all
    fours with our interpretation of the Massachusetts statute at issue
    in this case.       It cannot, however, be squared with our dissenting
    colleague's reading of the nexus requirement articulated in Matter
    of    Valenzuela    Gallardo.      Nor   can   it   be   reconciled    with    our
    dissenting colleague's mens rea\actus reus analysis, because like
    Matter of Valenzuela Gallardo, Matter of Cordero-Garcia relies
    solely on a specific intent requirement.
    B.     Alternatively, If § 1101(a)(43)(S) Were Ambiguous, the BIA
    Would Prevail Under Chevron deference
    Assuming, arguendo, that the statute is ambiguous and
    thus subject to Chevron deference,22 we must defer to the BIA's
    interpretation.      See Scialabba v. Cuellar de Osorio, 
    573 U.S. 41
    ,
    56 (2014); Chevron, 
    467 U.S. at 844
    .
    Chevron deference applies where an agency has followed
    suitably formal procedures, see United States v. Mead Corp., 
    533 U.S. 218
    ,    229-30   (2001),    to   interpret       a   civil   statute    it
    administers, see Gonzales v. Oregon, 
    546 U.S. 243
    , 265 (2006).                  In
    applying Chevron, we follow a familiar two-step pathway.                  First,
    we determine whether the statute is ambiguous.               Second, if it is,
    we defer to the responsible agency's reasonable interpretation of
    the ambiguous text.       See Chevron, 
    467 U.S. at 842-43
    .
    22 In light of Esqiuvel-Quintana, it is not clear which
    interpretive approach we should employ, so we use both.
    - 34 -
    1.     At "Step Zero," the BIA's               Interpretation    Is
    Eligible for Chevron Deference
    The BIA's administration of the INA falls within Mead's
    safe harbor for formal adjudications.            See Mead, 
    533 U.S. at
    226-
    27; see also Negusie v. Holder, 
    555 U.S. 511
    , 517 (2009).                       Its
    interpretation of § 1101(a)(43)(S) carries the force of law and
    thus falls within Chevron's domain.             See Mead, 
    533 U.S. at
    226-
    27; see also T.W. Merrill & K.E. Hickman, Chevron's Domain, 
    89 Geo. L.J. 833
     (2001).           Silva attempts to avoid that inexorable
    conclusion, arguing that the decision in his case was unpublished
    and thus not binding on future parties.           That contention, however,
    looks     to    the     wrong   decision.       The     BIA    established      its
    interpretation in a published decision issued by a three-member
    panel in Matter of Valenzuela Gallardo.               See 27 I. & N. Dec. at
    449.    Once the BIA formally interprets a statue, we may defer to
    subsequent informal applications of the interpretation.                  Garcia-
    Mendez v. Lynch, 
    788 F.3d 1058
    , 1061 (9th Cir. 2015) (citing
    Neguise, 
    555 U.S. at 516
    ).               To require each decision to be
    published      by   a   three-member    panel   would    be    to   require    more
    procedural safeguards than Congress intended.                    Cf. Vt. Yankee
    Nuclear Power Corp. v. Nat. Res. Def. Council, 
    435 U.S. 519
    , 524
    (1978).
    Additionally, Silva's contention that we cannot defer to
    the BIA's interpretation of a statute with criminal implications
    - 35 -
    is    misguided.     We     have    previously      deferred     to    the    BIA's
    interpretation of the definition of aggravated felonies,23 see,
    e.g., Soto-Hernandez v. Holder, 
    729 F.3d 1
    , 5 (1st Cir. 2013);
    Lecky v. Holder, 
    723 F.3d 1
    , 5 (1st Cir. 2013), and continue to do
    so here.24
    To hold otherwise would be flatly inconsistent with
    precedents both of this Court and the Supreme Court.                   In Chevron
    itself, the Supreme Court deferred to the EPA's interpretation of
    the    Clean   Air   Act,    even     though    knowing       violation      of   an
    implementation plan under that act carried criminal penalties.
    See Guedes v. Bureau of Alcohol, Tobacco, Firearms & Explosives,
    
    920 F.3d 1
    , 24 (D.C. Cir. 2019) (citing 
    42 U.S.C. § 7413
    (c)(1)
    (1982)).       Similarly,    in     Babbitt    v.   Sweet     Home    Chapter     of
    Communities    for   a   Great     Oregon,    the   Supreme    Court    expressly
    considered the potential criminal penalties for a violation of the
    Endangered Species Act and deferred to the Secretary of the
    Interior's interpretation of that law.              
    515 U.S. 687
    , 702-704 &
    704 n.18.      We regularly defer to interpretations of the IRS
    Commissioner even though violating tax regulations can result in
    23  Silva and amici also argue that our previous decisions
    did not expressly address his proposed "dual-application statute"
    exception to Chevron. We now hold that no such exception exists.
    24   Our holding certainly does not run afoul of the Supreme
    Court's observation in United States v. Appel that it has "never
    held that the Government's reading of a criminal statutes is
    entitled to any deference." 
    571 U.S. 359
    , 369 (2014).
    - 36 -
    criminal penalties.      See, e.g., Dikow v. United States, 
    654 F.3d 144
    , 149-51 (1st Cir. 2011); see also United States v. O'Hagan,
    
    521 U.S. 642
    , 647 (1997).        Indeed, regulatory offenses carrying
    criminal penalties are legion in the Code of Federal Regulations,
    see generally M. Chase, How to Become a Federal Criminal (2019),
    but we continue to defer to agencies' interpretations of the
    underlying statutes.
    2.   Assuming § 1101(a)(43)(S) Is Ambiguous, the BIA's
    Interpretation of it Is Reasonable
    We explained earlier why interpreting § 1101(a)(43)(S)
    to encompass Massachusetts accessory after the fact is reasonable.
    See supra Part II.A. The BIA's understanding of the statute cannot
    be said to be beyond the "bounds of reasonable interpretation."

    , 321 (2014)).

    at their apex and judicial powers are at their nadir."      Hernandez-

    , 54 (Lynch, J., dissenting).        Congress

    administering the INA."       Neguise, 
    555 U.S. at 516-17
    .       Thus,
    "[j]udicial deference in the immigration context is of special
    importance, for executive officials 'exercise especially sensitive
    political    functions    that    implicate   questions   of   foreign
    relations.'"     
    Id. at 517
     (quoting INS v. Abudu, 
    485 U.S. 94
    , 110
    - 37 -
    (1988)).     Compared to the executive, "[t]he judiciary is not well
    positioned to shoulder primary responsibility for assessing the
    . . .   diplomatic       repercussions"       of     sensitive       immigration
    decisions.    INS v. Aguirre-Aguirre, 
    526 U.S. 415
    , 425 (1999); see
    Griffiths v. INS, 
    243 F.3d 45
    , 49 (1st Cir. 2001).                    The BIA's
    exercise of its Congressionally assigned functions certainly was
    not unreasonable.
    C.   The IJ and BIA Did Not Err in Determining That Silva's
    Massachusetts Accessory-After-the-Fact Conviction Was a
    "Particularly Serious Crime" for Purposes of Denying
    Withholding of Removal
    Silva   also   argues    that    even    if   his   Massachusetts
    conviction is an aggravated felony under § 1101(a)(43)(S), it is
    not a particularly serious crime that bars him from withholding of
    removal.     The parties dispute whether the appropriate standard of
    review of the BIA's particularly-serious-crime determination is de
    novo or only for substantial evidence.               We need not decide this
    issue because we conclude that there was no error under either
    standard of review.
    Under Matter of N-A-M-, 
    24 I. & N. Dec. 336
     (B.I.A.
    2007), overruled in part on other grounds by Blandino-Medina v.
    Holder, 
    712 F.3d 1338
    , 1347-48 (9th Cir. 2013), which Silva does
    not challenge, the BIA "examine[s] the nature of the conviction,
    the type of sentence imposed, and the circumstances and underlying
    facts   of    the    conviction"     in   determining      whether    it   is   a
    - 38 -
    particularly serious crime.       
    Id. at 342

    likely to be considered particularly serious if it is against a
    person . . . ."   Matter of R-A-M-,

    , 662 (B.I.A.
    2012) (citing Matter of N-A-M-, 24 I. & N. Dec. at 343).              And
    factual   findings   made   by   the   BIA   in   determining   whether   a
    conviction is for "a particularly serious crime" are "conclusive
    unless any reasonable adjudicator would be compelled to conclude
    to the contrary," which "is a 'highly deferential' standard."
    Garland v. Ming Dai, 
    141 S. Ct. 1669
    , 1674, 1677 (2021) (first
    quoting 
    8 U.S.C. § 1252
    (b)(4)(B); and then quoting Nasrallah v.
    Barr, 
    140 S. Ct. 1683
    , 1692 (2020)).
    The record supports the BIA's determination that, based
    on his guilty plea to the Massachusetts indictment, Silva admitted
    to knowing that the individuals whom he assisted had committed a
    murder.   Based on that finding and Silva's conduct in aiding known
    murderers to avoid or escape apprehension and punishment, the BIA
    did not commit any legal or other error in determining that the
    accessory-after-the-fact conviction was a particularly serious
    crime which rendered him ineligible for withholding of removal.
    III.
    Silva's petition for review of the BIA's final order of
    removal is denied.
    -DISSENTING OPINION FOLLOWS-
    - 39 -
    BARRON, Circuit Judge, dissenting. Is the crime of being
    an accessory after the fact to a "felony" under Massachusetts law,
    see   
    Mass. Gen. Laws ch. 274, § 4
    ,   an     "offense   relating    to
    obstruction of justice" under the Immigration and Nationality Act
    ("INA"),    
    8 U.S.C. § 1101
    (a)(43)(S),         such    that   this   state-law
    accessorial crime constitutes an "aggravated felony" and thus
    makes the lawful permanent resident convicted of committing it
    removable and ineligible for asylum, see 
    8 U.S.C. §§ 1158
    (b)(2),
    1227(a)(2)(A)(iii)?              In concluding in this case that this state-
    law accessorial crime is "an offense relating to obstruction of
    justice"      under        § 1101(a)(43)(S),       the      majority     rejects    the
    reasoning of the Third Circuit in Flores v. Attorney General, 
    856 F.3d 280
     (3d Cir. 2017), and the Ninth Circuit in Valenzuela
    Gallardo v. Barr (Valenzuela Gallardo IV), 
    968 F.3d 1053
     (9th Cir.
    2020).     But, even accepting that the majority is right to reject
    the reasoning of those courts, it is wrong to uphold the ruling of
    the Board of Immigration Appeals ("BIA") that the Massachusetts
    accessory-after-the-fact offense of which Carlos Monteiro Silva
    was   convicted       is    an    "obstruction    of     justice"-related      offense
    within the meaning of § 1101(a)(43)(S).
    I.
    It helps first to explain exactly how the majority's
    construction of § 1101(a)(43)(S) differs from that of the Third
    Circuit in Flores and the Ninth Circuit in Valenzuela Gallardo IV.
    - 40 -
    Each of those cases rejected the construction of the phrase "an
    offense relating to obstruction of justice" in § 1101(a)(43)(S)
    that   the   BIA   had    adopted   in    Matter      of    Valenzuela    Gallardo
    (Valenzuela Gallardo III), 
    27 I. & N. Dec. 449
     (BIA 2018).
    The Third and Ninth Circuits held that the "obstruction
    of justice"-related offense referred to in that federal statute
    requires proof of a much tighter nexus than the BIA in Valenzuela
    Gallardo III had held that the offense requires between an official
    investigation      or    proceeding       and   the        obstructive    conduct.
    Specifically, those courts held that the required nexus needs to
    be between the obstructive conduct and an official investigation
    or proceeding that, at the time of that conduct, was at least
    pending   and   not,     for   example,    merely     reasonably    foreseeable.
    Valenzuela Gallardo IV, 968 F.3d at 1068; Flores, 856 F.3d at 292-
    294.
    Moreover, on that basis, the Third and Ninth Circuits
    rejected the BIA's determination in each of the cases before them
    that an accessory after the fact offense that did not require proof
    of such a tight nexus could be "an offense relating to obstruction
    of justice" within the meaning of § 1101(a)(43)(S).                      Valenzuela
    Gallardo IV, 968 F.3d at 1069; Flores, 856 F.3d at 293-96.                    And,
    the Third and Ninth Circuits further held, persuasively in my view,
    that the words "relating to" in § 1101(a)(43)(S) -- though words
    of inclusion -- do not bring within the scope of the offense
    - 41 -
    referred to in that provision an offense that is not itself an
    "obstruction of justice" offense at all.         Valenzuela Gallardo IV,
    968 F.3d at 1068; Flores, 856 F.3d at 290-91, 296.
    In   Silva's   case,   the   BIA   embraced   the   same   looser
    description of the nexus requirement that the BIA had embraced in
    Valenzuela Gallardo III and that the Third and Ninth Circuits
    rejected for not being tight enough.         The BIA then ruled based on
    that understanding of the nexus requirement that Silva's state-
    law accessorial offense is an "offense relating to obstruction of
    justice" under § 1101(a)(43)(S).
    Silva now contends that we must reject the BIA's ruling
    in his case for essentially the reasons that Flores and Valenzuela
    Gallardo IV gave in ruling as they did in those cases.         But, Silva
    does not ask us to overturn the BIA's ruling only by asking us to
    endorse the tighter nexus that the Third and Ninth Circuits
    described.   He also contends, as a fallback argument, that even if
    we were to accept that the BIA has correctly described the nexus
    requirement to be looser than the Third and Ninth Circuits held it
    to be, the Massachusetts accessory-after-the-fact offense of which
    he was convicted would not be an "offense relating to obstruction
    of justice" under § 1101(a)(43)(S) because the least of the conduct
    that this accessorial offense criminalizes would still not be
    encompassed by that generic, federal "obstruction of justice"-
    - 42 -
    related offense.     See Moncrieffe v. Holder, 
    569 U.S. 184
    , 190-91
    (2013).
    As    I   will    explain,      Silva's    fallback     argument   for
    granting his petition for review is a winning one.                     For that
    reason, the majority's holding that the BIA's construction of the
    nexus requirement for "an offense relating to obstruction of
    justice" is a reasonable one under Chevron, U.S.A., Inc. v. Natural
    Resources Defense Council, Inc., 
    467 U.S. 837
     (1984), provides no
    basis for me to conclude otherwise.          In that holding, the majority
    just endorses -- after drawing on the approach for interpreting
    § 1101(a)(43)     that    the   Supreme    Court    set   forth   in   Esquivel-
    Quintana v. Sessions, 
    137 S. Ct. 1562
     (2017) -- the reasonableness
    of   construing     the    "obstruction      of    justice"-related     offense
    referred to in § 1101(a)(43)(S) to be constrained only by a nexus
    requirement that is as loose as the one that the BIA has described.
    For, as Silva persuasively contends, the BIA's construction of "an
    offense relating to obstruction of justice" -- given the looseness
    of that construction's understanding of the nexus requirement --
    still defines that offense to encompass more conduct than the least
    of the conduct that Silva's accessorial offense of conviction
    encompasses.
    But, I emphasize, I also can see no reason to reject
    Silva's fallback argument insofar as the majority independently
    means to hold -- again pursuant to Esquivel-Quintana but this time
    - 43 -
    without purporting to afford any deference under Chevron -- that
    the generic, federal "obstruction of justice"-related offense to
    which § 1101(a)(43)(S) refers is not constrained by any nexus
    requirement at all.    For, under SEC v. Chenery Corp., 
    318 U.S. 80
    ,
    94 (1943), we cannot sustain the BIA's ruling in Silva's case based
    on such a nexus-less construction of that offense unless we are
    bound to adopt that construction to the exclusion of the nexus-
    based one that the BIA has set forth and that the majority itself
    agrees is reasonable.    And, as I will explain, the majority offers
    no persuasive reason to conclude that a nexus-less construction
    must be adopted over the nexus-based one that the BIA has set
    forth.
    II.
    Before turning to the majority's independent holding
    endorsing a nexus-less construction of the offense referred to in
    § 1101(a)(43)(S), it makes sense to start with the majority's more
    modest one.    True, the majority concludes in that holding that the
    offense requires some such nexus to be shown and that the BIA's
    operative description of that nexus requirement is a reasonable
    one.     But, as I will explain, that holding provides no basis for
    rejecting Silva's petition for review, despite being nexus-based.
    To show why, it is necessary, as an initial matter, to explain in
    more detail just what the BIA's operative understanding of that
    nexus requirement is.    I thus now turn to that task.
    - 44 -
    A.
    In Valenzuela Gallardo III, the BIA was attempting to
    address a Ninth Circuit ruling that had rejected a prior BIA
    construction of § 1101(a)(43)(S).         See 27 I. & N. Dec. at 451-52.
    The Ninth Circuit had held that the BIA's earlier construction
    rendered the "obstruction of justice"-related offense to which
    § 1101(a)(43)(S) refers too vague.             See Valenzuela Gallardo v.
    Lynch (Valenzuela Gallardo II), 
    818 F.3d 808
    , 812, 824 (9th Cir.
    2016),   vacating   and   remanding    Matter     of   Valenzuela    Gallardo
    (Valenzuela Gallardo I), 25 I. & N. 838 (BIA 2012).           That was so,
    the Ninth Circuit explained, because that construction did not
    require as an element of that offense any nexus between the
    defendant's obstructive conduct and an official investigation or
    proceeding and so left unclear the kind of conduct that would
    qualify as obstructive.     
    Id.
    To address that concern, the BIA explained in Valenzuela
    Gallardo III that, in accord with Esquivel-Quintana, it would draw
    its   revised   understanding     of     the    offense   referred    to   in
    § 1101(a)(43)(S) from "Federal and State law, Federal sentencing
    guidelines, the Model Penal Code, and scholarly commentary."               27
    I. & N. Dec. at 452-53 (citing Esquivel-Quintana, 
    137 S. Ct. at 1570-72
    ).    The BIA then focused heavily, though not exclusively,
    on the offenses set forth in Chapter 73 of the federal criminal
    code, which is entitled "Obstruction of Justice."           Id. at 453-56.
    - 45 -
    In canvassing those materials, the BIA in Valenzuela
    Gallardo III acknowledged that most of the offenses in Chapter 73
    contained a quite tight nexus requirement; the provisions in that
    chapter that set forth those offenses made clear that they could
    be committed only if the defendant obstructed an investigation or
    proceeding that was in fact pending.         Id. at 454.    But, the BIA
    also noted that the "Obstruction of Justice" offense set forth in
    
    18 U.S.C. § 1512
     was different.       
    Id.
    At the time that § 1101(a)(43)(S) was enacted, the BIA
    pointed out, § 1512 provided in relevant part that it was a crime
    knowingly to use "intimidation, physical force, threats, corrupt
    persuasion, or misleading conduct toward another person with the
    intent to . . . 'hinder, delay, or prevent the communication to a
    law   enforcement   officer   or    judge   of   the   United   States   of
    information relating to the commission or possible commission of
    a Federal offense.'"    Id. (emphasis omitted) (quoting 
    18 U.S.C. § 1512
    (b) (1994)).    The BIA then also explained that the Supreme
    Court in Marinello v. United States, 
    138 S. Ct. 1101
     (2018), had
    offered a "synthesi[s]" of the cases that had construed § 1512's
    nexus requirement and that the Court in Marinello had relied on
    that body of precedent to define the nexus required under the
    Internal Revenue Code provision that was there at issue, which
    made it a crime to interfere with investigations into tax crimes,
    see 
    26 U.S.C. § 7212
    (a).      27 I. & N. Dec. at 455.
    - 46 -
    The BIA explained that, in setting forth the synthesis
    of    the    case   law      that   concerned        § 1512's      nexus   requirement,
    Marinello made clear that § 1512 required proof of a nexus between
    the defendant's obstructive conduct and an official investigation
    that was merely "'reasonably foreseeable by the defendant' at the
    time of the obstructive conduct" rather than pending as of that
    time.       Valenzuela Gallardo III, 27 I. & N. Dec. at 455 (quoting
    Marinello, 
    138 S. Ct. at 1110
    ).                      The BIA also explained that
    Congress       would        have    been    aware         of     that    Marinello-based
    understanding          of     § 1512's      nexus         requirement      in     enacting
    § 1101(a)(43)(S).           Id. at 455-56.          Based on that conclusion about
    what    Congress     would     have    known,       the    BIA    then   relied    on   the
    Marinello-based understanding of the required nexus in § 1512 to
    define "an offense relating to obstruction of justice" in a way
    that encompassed obstructive conduct so long as it was connected
    to "reasonably foreseeable" proceedings or investigations.
    It is thus clear that Valenzuela Gallardo III was relying
    on    Marinello's      understanding          of    the    "reasonably     foreseeable"
    standard for defining the required nexus to address the vagueness
    concern that had led the Ninth Circuit to reject the BIA's prior
    nexus-less construction of § 1101(a)(43)(S).                      And, that is notable
    for     present     purposes        because        Marinello      explained     that    the
    "reasonably foreseeable" standard, though more expansive than a
    - 47 -
    pending-investigation-or-proceeding standard such as the Third and
    Ninth Circuits had embraced, is still importantly constrained.
    Specifically, the Court in Marinello made a point of
    explaining   that    to      demonstrate      that    a    "proceeding"        or
    "investigation" was "reasonably foreseeable" at the time of the
    obstructive conduct, "[i]t is not enough for the Government to
    claim that the defendant knew [law enforcement] may catch on to
    his unlawful scheme eventually.         To use a maritime analogy, the
    proceeding must at least be in the offing."           Marinello, 
    138 S. Ct. at 1110
    . Thus, Marinello clearly rejected the notion that evidence
    that a defendant had engaged in a tax scheme that was unlawful
    could suffice in and of itself to prove that the "reasonably
    foreseeable"-based    nexus    requirement     had    been      met   under   the
    federal tax crime there at issue for "obstruct[ing] or imped[ing]
    . . . the due administration" of Title 26.           See 
    id.
     (discussing 
    26 U.S.C. § 7212
    (a)).
    Indeed, were that not so, the Court could have just said
    that proof of the defendant's predicate unlawful tax scheme would
    suffice to satisfy that nexus requirement for the offense defined
    in 
    26 U.S.C. § 7212
     rather than that proof that law enforcement
    "may catch on to" that scheme "eventually" would not be enough to
    satisfy that requirement.       After all, proof of the existence of
    the   predicate   unlawful    tax   scheme,    in    and   of   itself,   would
    necessarily constitute proof that at least such a mere eventuality
    - 48 -
    was possible.    And, indeed, our own precedent accords with this
    same understanding of the narrowing import of Marinello's "in the
    offing" gloss on the "reasonably foreseeable" standard that the
    Court there described as constraining the nexus requirement not
    only for the offense at issue in that case but also for those like
    it, such as the one set forth in § 1512.             See United States v.
    Takesian, 
    945 F.3d 553
    , 566-67 (1st Cir. 2019) (concluding a
    proceeding was reasonably foreseeable to the defendant under the
    Marinello standard because he knew that "the [Internal Revenue
    Service] was investigating the money trail that could lead to him"
    and because he testified that "he believed investigators put the
    screws on him").25
    There is, of course, a separate question regarding the
    element   or   elements   of   the    "obstruction   of   justice"-related
    offense referred to in § 1101(a)(43)(S) that the BIA understood to
    be constrained by the nexus requirement to which this "reasonably
    25The majority notes that the phrase "in the offing" "refers,
    in the maritime sense, to '[t]he part of the sea visible from the
    shore that is very distant or beyond anchoring ground.'" Maj. Op.
    at 29 n.19 (quoting Offing, The American Heritage Dictionary of
    the English Language 1223 (5th ed. 2018)). The majority emphasizes
    the "very distant" portion of this definition; to me, the most
    important part for present purposes is the "visible" part. But,
    we need not parse the dictionary entry too finely because Marinello
    makes clear that it used the phrase "in the offing" to establish
    that the government has not proven an investigation to have been
    "reasonably foreseeable" when all it has shown is that "the
    defendant knew [law enforcement] may catch on to his unlawful
    scheme eventually," 
    138 S. Ct. at 1110
    .
    - 49 -
    foreseeable" standard applies. I have thus far described the nexus
    requirement as if it constrains the elements of that offense that
    define its actus reus and not merely its mens rea.         And, that is
    for good reason.
    The BIA, after having canvassed Chapter 73, Marinello,
    and other aspects of federal and state law, as well as other
    materials, expressly laid out the elements of the "obstruction of
    justice"-related offense in § 1101(a)(43)(S) as follows: "(1) an
    affirmative and intentional attempt (2) that is motivated by a
    specific   intent   (3)   to   interfere   with   an   investigation   or
    proceeding that is ongoing, pending, or 'reasonably foreseeable by
    the defendant.'"    Valenzuela Gallardo III, 27 I. & N. Dec. at 460
    (emphasis added).    Given the BIA's use of the word "attempt" in
    "(1)," and the word "is" in "(3)," the BIA must be read here to be
    describing the nexus requirement as a constraint on -- at least --
    the scope of the offense's actus reus and not only on its mens
    rea.26
    26 Nor should we be surprised that the BIA in Valenzuela
    Gallardo III chose to treat the "reasonably foreseeable" standard
    as a constraint that limited -- at least -- the actus reus of the
    generic, federal "obstruction of justice"-related offense. As we
    have seen, the BIA there was borrowing the "reasonably foreseeable"
    standard from the one that the Court had announced in Marinello.
    And, Marinello clearly treated that standard as if it were a
    constraint on the actus reus of the offense there at issue rather
    than only on the offense's mens rea. Specifically, in articulating
    the "reasonably foreseeable" constraint on the scope of the offense
    set forth in § 7212 of Title 26, Marinello focused its interpretive
    - 50 -
    As a result, I understand the BIA in Valenzuela Gallardo
    III to describe the offense referred to in § 1101(a)(43)(S) as one
    that requires proof of a nexus between the obstructive conduct and
    an    investigation    or     proceeding      that    is    in   fact   reasonably
    foreseeable at the time of that conduct.                   I thus understand the
    BIA to describe that offense in a manner that is at odds with the
    notion that proof that the defendant merely believed at that time
    (even    if    mistakenly)     that     an    investigation      was    reasonably
    foreseeable could be enough.
    That said, I am aware that the BIA in Valenzuela Gallardo
    III     did   assert   that    Congress       intended      § 1101(a)(43)(S)    to
    encompass both the federal accessory-after-the-fact offense, 
    18 U.S.C. § 3
    , and the California accessory-after-the-fact offense at
    issue in that case, too.            27 I. & N. Dec. at 459, 461 & n.17.          I
    am also aware that the BIA in that case explained that each of
    these accessorial offenses is encompassed by § 1101(a)(43)(S)
    because of its mens rea element -- in the case of the federal one,
    the    specific    intent     "to    hinder     or   prevent     [an    offender's]
    lens on the phrases "obstructs or impedes" and "due administration"
    in that statute.    
    138 S. Ct. at 1106
    .     Each of those phrases
    concerns the actus reus of the offense that the statute sets forth.
    By contrast, the consensus among lower courts at the time was that
    "the statute's mens rea requirement" was embodied in the word
    "corruptly" in that statute, United States v. Miner, 
    774 F.3d 336
    ,
    347 (6th Cir. 2014) (collecting cases); see also United States v.
    Sorensen, 
    801 F.3d 1217
    , 1229-30 (10th Cir. 2015), which is a word
    that was not at issue in Marinello.
    - 51 -
    apprehension, trial or punishment," 
    18 U.S.C. § 3
    , and in the case
    of the California one, the specific intent "to interfere either in
    an ongoing, pending, or reasonably foreseeable investigation or
    proceeding," 27 I. & N. Dec. at 461.             Finally, I am aware that in
    theory such an intent could be proved without there being proof
    that any such investigation or proceeding was in fact reasonably
    foreseeable at the time of the defendant's accessorial conduct.
    See People v. Rizo, 
    996 P.2d 27
    , 30-31 (Cal. 2000) (holding that
    "a specific intent crime" that "focuses solely on the acts and
    intent of the violator" may be committed even if the defendant's
    intent is based on a mistaken understanding).
    Nonetheless,     as     I    have    explained,    the   BIA,     after
    completing    its    analysis     of    § 1101(a)(43)(S)      in    accord    with
    Esquivel-Quintana, quite clearly described the actus reus of the
    offense to be "an affirmative and intentional attempt . . . to
    interfere with an investigation or proceeding that is ongoing,
    pending,     or     'reasonably        foreseeable   by      the    defendant.'"
    Valenzuela Gallardo III, 27 I. & N. Dec. at 460 (emphasis added).
    And, the government in its briefing to us cites to that same
    description in describing the BIA's understanding of the nexus
    requirement just as I have.            Thus, in light of the BIA's express
    description of the elements of the offense in § 1101(a)(43)(S), I
    see no basis for concluding that the BIA has set forth a reasoned
    basis for construing that offense's actus reus to be unconstrained
    - 52 -
    by the "reasonably foreseeable"-based nexus requirement.       Cf.
    Pugin v. Garland, 
    19 F.4th 437
    , 450 (4th Cir. 2021) (noting that
    courts "give no deference to the Board's construction of state law
    or determination of its fit with federal law," despite the court's
    finding that deference was due to the BIA's interpretation of
    § 1101(a)(43)(S)); Higgins v. Holder, 
    677 F.3d 97
    , 109 (2d Cir.
    2012) (Katzmann, J., concurring) (same).27
    27 In the same "Application" section of Valenzuela Gallardo
    III in which the BIA discussed the California statute, it explained
    that the    Marinello-informed, "reasonably foreseeable"-based
    construction of the nexus requirement for the actus reus of "an
    offense relating to obstruction of justice" that it was adopting
    was "consistent with [its] prior holdings." Valenzuela Gallardo
    III, 27 I. & N. Dec. at 460. It then pointed to cases in which it
    had held that although the offense set forth by the federal
    accessory-after-the-fact statute, 
    18 U.S.C. § 3
    , is an "offense
    relating to obstruction of justice" under the INA, the offense set
    forth in the federal misprision of felony statute, 
    id.
     § 4, is
    not.   Valenzuela Gallardo III, 27 I. & N. Dec. at 460 (citing
    Matter of Espinoza-Gonzalez, 
    22 I. & N. Dec. 889
    , 894 (BIA 1999)
    and In re Batista-Hernandez, 
    21 I. & N. Dec. 955
    , 962 (BIA 1997)).
    And, the BIA did so with reference to the specific intent element
    of the federal accessory-after-the-fact offense. 
    Id. at 461
    . But,
    Valenzuela Gallardo III did not explain in discussing Espinoza --
    which pre-dated Marinello itself -- how an element of an
    accessorial offense that requires proof of merely a purpose to
    interfere with an investigation in and of itself could suffice to
    make an offense one "relating to obstruction of justice," given
    Valenzuela Gallardo III's Marinello-based rationale for expressly
    holding that Congress must be understood to have intended the actus
    reus of an offense "relating to obstruction of justice" to require
    proof of a nexus between the obstructive conduct and a reasonably
    foreseeable investigation or proceeding. I thus also see no basis
    for concluding from Valenzuela Gallardo III's discussion of
    Espinoza that Valenzuela Gallardo III's Marinello-informed, actus
    reus-based definition of the nexus requirement is not the operative
    one.   Nor does the government suggest otherwise, given that it
    describes the BIA's operative understanding of the elements of the
    - 53 -
    B.
    There is one hanging thread.         The majority asserts that
    it is wrong to read the BIA as "requir[ing] an identical nexus in
    both the statute at issue [in Marinello], 
    26 U.S.C. § 7212
    , and
    the statute at issue here, § 1101(a)(43)(S)."               Maj. Op. at 32.
    In support of this assertion, the majority first points
    to a statement by the BIA in Valenzuela Gallardo III in which it
    supposedly "expressly rejected that false equivalence."                 Id.   The
    statement from Valenzuela Gallardo III that the majority has in
    mind is the one in which the BIA observes that Congress intended
    § 1101(a)(43)(S) "to apply more broadly than" 
    26 U.S.C. § 7212
     and
    
    18 U.S.C. § 1503
    , the section of Chapter 73 that defines the
    "catch-all" "obstruction of justice" offense.                 Maj. Op. at 32
    (quoting Valenzuela Gallardo III, 27 I. & N. Dec. at 454 n.6).
    But, a closer examination of the BIA's decision reveals
    that the purported "express[] reject[ion]" that statement makes
    has nothing to do with the scope of the nexus requirement for "an
    offense     relating      to       obstruction        of     justice"     under
    § 1101(a)(43)(S).      Read in context, the footnoted statement aims
    only   to   make    the   simple    point    that     the   generic,    federal
    "obstruction   of    justice"-related       offense    that    Congress   there
    referred to encompasses crimes other than the two specific federal
    actus reus of the "obstruction of justice"-related                      offense
    referred to it § 1101(a)(43)(S) just as I do.
    - 54 -
    offenses set forth respectively in 
    18 U.S.C. § 1503
     and 
    26 U.S.C. § 7212
     -- as it plainly does.          See Valenzuela Gallardo III, 27 I.
    & N. Dec. at 454 & n.6.         The footnoted statement thus clarifies
    that § 1101(a)(43)(S) is referring to a crime that encompasses
    even, for example, state-law crimes that criminalize the same swath
    of conduct as the generic, federal "obstruction of justice" offense
    to which § 1101(a)(43)(S) refers.
    In performing that clarifying function, the footnoted
    statement in no way purports to be defining anew the scope of the
    nexus    requirement     for   the   generic,      federal    "obstruction       of
    justice"-related    offense     or     the    meaning    of   the   "reasonably
    foreseeable" standard that constrains the nexus requirement of
    that offense's actus reus.       The BIA in the main body of its opinion
    relied   heavily   on    Marinello,     as    I   have   described,      and   then
    expressly cited Marinello and United States v. Aguilar, 
    515 U.S. 593
     (1995), which construed the nexus requirement in § 1503, see
    id. at 599-600, when it set forth the elements of "an offense
    relating to obstruction of justice," see Valenzuela Gallardo III,
    27 I. & N. Dec. at 456.        It would be strange for the BIA to then
    redefine   a   portion    of   those   elements     in   a    footnote    without
    addressing why.
    The majority also points to a BIA case decided after
    Valenzuela Gallardo III that, the majority contends, demonstrates
    that the BIA did not intend to rely on Marinello to define the
    - 55 -
    actus reus of "an offense relating to obstruction of justice."
    Maj. Op. at 33-34 (discussing Matter of Cordero-Garcia, 
    27 I. & N. Dec. 652
     (BIA 2019)).      But, the BIA there did not purport to reject
    its earlier clear statement of the actus reus of the offense as
    being subject to a "reasonably foreseeable" standard.              Nor do I
    read   the    BIA   in   Cordero-Garcia   to    have   suggested   that   the
    "reasonably foreseeable" standard that constrains the actus reus
    of "an offense relating to obstruction of justice" is not itself
    constrained by the "in the offing" gloss that Marinello placed on
    it.    Rather, I read Cordero-Garcia to have accepted Valenzuela
    Gallardo III's description of the actus reus of that offense as
    being subject to such a "reasonably foreseeable"-constrained --
    and Marinello-informed -- nexus requirement and then to have
    concluded that, even still, the state law offense at issue there
    qualified as "an offense relating to obstruction of justice" under
    § 1101(a)(43)(S).        See Cordero-Garcia, 27 I. & N. Dec. at 654
    (relying on the "specific intent" element of a California criminal
    offense to find that the offense was a categorical match to the
    generic, federal offense set out in § 1101(a)(43)(S)).
    In other words, I read Cordero-Garcia to be no different
    from Valenzuela Gallardo III or the BIA decision in Silva's case.
    It, too, embraces an understanding of the actus reus of "an offense
    relating     to   obstruction   of   justice"   that   is   nexus-based   and
    constrained by the reasonably foreseeable standard that Marinello
    - 56 -
    sets   forth.       And,    it,   too,    does    so   notwithstanding      that   it
    concludes    that    a     state-law      accessorial      offense    is   such    an
    "obstruction of justice"-related offense even though that state-
    law accessorial offense has no similarly constrained actus reus.
    I also emphasize that, in concluding that the BIA has not yet
    backed away from Valenzuela Gallardo III's quite clear description
    of the offense's actus reus, I am taking a position that the
    government      itself     appears   to    share,      given   the   way   that    the
    government's briefing to us describes the understanding of actus
    reus of the offense that the BIA embraced in Valenzuela Gallardo
    III and re-embraced yet again in the case before us.
    III.
    With the BIA's operative understanding of the nexus
    requirement for "an offense relating to obstruction of justice"
    now in view, I am almost ready to address whether Silva's offense
    of conviction is such an offense.                 But, before taking up that
    question -- which, as I will explain, is the dispositive one in
    this case -- there remains one more task to complete.                  It concerns
    the majority's independent, Chevron-free holding that I mentioned
    at the outset.
    In that holding, the majority appears to conclude that,
    insofar as we are not bound to defer under Chevron to the BIA's
    nexus-based      construction        of     the     offense     referred     to     in
    § 1101(a)(43)(S), that offense may reasonably be construed under
    - 57 -
    the interpretive approach set forth in Esquivel-Quintana not to be
    subject to a nexus requirement at all.        And, the majority then
    appears to go on to conclude in that holding that Silva's petition
    must be rejected for this reason, too.
    But, notably, the majority does not explain in so holding
    what basis there is for not applying Chevron here.         It does not
    suggest, for example, that the BIA's nexus-based construction of
    the   "obstruction   of   justice"-related   offense   referred   to   in
    § 1101(a)(43)(S) is an unreasonable one, such that the BIA's
    construction would not be entitled to deference for that reason.
    In fact, the majority holds the opposite.
    Nor does the majority suggest that Chevron deference is
    not available to the interpretive question at hand, even if the
    BIA's construction is a reasonable one.         Rather, the majority
    rejects each of Silva's arguments to that effect as well as those
    of the amici and even explains why our precedents leave us, as a
    panel, with no basis for rejecting Chevron's application to the
    extent that the BIA's nexus-based construction is a reasonable
    one.28
    I note in this regard that I agree with the majority that
    28
    there is no basis for this panel to hold that Chevron has no
    application at all, given that we have three times before upheld
    BIA constructions of other provisions of this same part of the INA
    under Chevron. See De Lima v. Sessions, 
    867 F.3d 260
    , 264-65 (1st
    Cir. 2017); Soto-Hernandez v. Holder, 
    729 F.3d 1
    , 3-5 (1st Cir.
    2013); Lecky v. Holder, 
    723 F.3d 1
    , 5 (1st Cir. 2013). I also
    - 58 -
    There is, though, still one more problem with holding
    that Silva's petition must be rejected under Esquivel-Quintana
    based on a nexus-less construction of the "obstruction of justice"-
    related offense referred to in § 1101(a)(43)(S). And, that problem
    stems from the fact that the majority does not explain at any point
    how, insofar as Chevron somehow does not apply here, the Esquivel-
    Quintana factors favor the adoption of a nexus-less construction
    of that offense to the exclusion of the nexus-based one that the
    BIA describes.
    The majority does, in applying those factors, advance
    reasons to reject the strict, pending-investigation-or-proceeding
    nexus requirement that the Third and Ninth Circuits have adopted.29
    emphasize, as the majority does as well, that the BIA here is not
    construing a provision of the federal criminal code.         It is
    construing a provision of the INA that determines the type of
    predicate offense that makes a lawful permanent resident removable
    and disqualifies a noncitizen from being eligible for asylum.
    29 I note in this regard that the majority invokes a series
    of dictionary definitions to support its contention that the Third
    and Ninth Circuits are wrong to hold that "an offense relating to
    obstruction of justice" requires proof of a nexus between
    obstructive conduct and an investigation or proceeding that, at
    the time of that conduct, is at least pending. But, even if those
    definitions support that conclusion, they do not themselves
    support a no-nexus understanding of the actus reus of "an offense
    relating to obstruction of justice." And, in fact, the majority
    does not attempt to explain how those definitions do.       Nor, I
    should add, do any of the provisions in Chapter 73 to which the
    majority refers provide support for a non-nexus understanding, as
    one of the two that the BIA might be read to suggest does so is 
    18 U.S.C. § 1512
     itself while the other one is expressly restricted
    to conduct committed "with the intent to facilitate an illegal
    gambling business," 
    18 U.S.C. § 1511
    (a) (1996).
    - 59 -
    And, I suppose, the majority could be understood in doing so also
    to be offering reasons that could explain why such a nexus-less
    construction is itself a permissible one.   I suppose as well that,
    The majority does identify some state law criminal codes that
    have grouped disparate offenses, some of which lack a nexus
    requirement, within a chapter or section and given the entire
    assortment the label of "obstruction of justice" or something
    similar.   But, the majority understandably does not go on to
    suggest on that basis that § 1101(a)(43)(S) is better read -- let
    alone best read even if the BIA reads the relevant materials
    otherwise -- to be referring to a nexus-less "obstruction of
    justice" offense. Cf. Jerome v. United States, 
    318 U.S. 101
    , 104
    (1943) ("[W]e must generally assume, in the absence of a plain
    indication to the contrary, that Congress when it enacts a statute
    is not making the application of the federal act dependent on state
    law.").
    The majority also points to the fact that the Model Penal
    Code identifies an accessory after the fact offense as "an
    independent offense of obstruction of justice." Maj. Op. at 26
    (quoting Model Penal Code § 242.1 explanatory note (Am. L. Inst.
    1985) [hereinafter MPC]). But, the majority does not hold that
    the only reasonable construction of § 1101(a)(43)(S) is one that
    tracks that understanding. That may be because the Model Penal
    Code did not even contain an offense labeled "obstruction of
    justice" at the time that § 1101(a)(43)(S) was enacted, see MPC
    §§ 242.1-.8, and because the Model Penal Code itself acknowledges
    that, under the "traditional concept" of "common law . . .
    accessory after the fact," a crime of that type was not "an
    independent offense of obstruction of justice," id. § 242.1
    explanatory note. Thus, here, too, the majority fails to offer a
    basis for favoring a nexus-less construction over the BIA's nexus-
    based one.
    Finally, although the majority relies on some precedent to
    assert that the federal accessory-after-the-fact statute, 
    18 U.S.C. § 3
    , has a "gist" of "essentially . . . obstructing
    justice," Maj. Op. at 18, it does not explain why one may conclude
    from that precedent alone that such a nexus-less construction is
    to be preferred to the BIA's nexus-based construction of the actus
    reus of "an offense relating to obstruction of justice." I also
    note in that regard that Congress itself saw fit to put that
    accessory-after-the-fact statute in a chapter other than Chapter
    73, which is the only chapter on which Congress chose to bestow
    the title, "Obstruction of Justice."
    - 60 -
    if we are not permitted to afford Chevron deference to the BIA's
    nexus-based construction despite its reasonableness, then we must
    adopt the nexus-less construction if it is superior to the BIA's.
    See H.J. Friendly, Chenery Revisited: Reflections on Reversal and
    Remand of Administrative Orders, 
    1969 Duke L.J. 199
    , 210.
    But, in light of Chenery, to justify the rejection of
    Silva's   petition     based     on   a     nexus-less      construction    of    the
    "obstruction     of     justice"-related            offense    referred     to     in
    § 1101(a)(43)(S), the majority must do more than explain merely
    why that nexus-less construction is as permissible as the nexus-
    based one that the BIA describes.                   For, without a reason to
    conclude that the nexus-less construction is superior, there is no
    reason to conclude that the nexus-based construction that the BIA
    has adopted and that it relied on in Silva's case is not a
    permissible one for it to have applied.                Yet, the majority at no
    point explains why (nor, for that matter, does the government) the
    nexus-less rather than the nexus-based construction is the one
    that the BIA would be bound to apply insofar as Chevron is not
    applicable.
    Thus,      because    I    see     no    basis     under   Chenery     for
    attributing     to     the   BIA      the     nexus-less       understanding       of
    § 1101(a)(43)(S) to which the majority adverts, I also see no basis
    for   denying    Silva's        petition      for     review     based     on    that
    understanding.       And so, unless the BIA's own understanding of the
    - 61 -
    nexus requirement for the "obstruction of justice"-related offense
    to which that provision refers encompasses the accessorial offense
    that Silva was convicted of under Massachusetts law, his petition
    must be granted.     All of which is to say that -- at last -- I can
    now move on to an assessment of the portion of the majority's
    opinion in which it holds pursuant to the BIA's nexus-based
    construction    of   the   "obstruction    of   justice"-related   offense
    referred to in § 1101(a)(43)(S) that Silva's conviction for being
    an accessory after the fact under Massachusetts law is an offense
    of that kind.
    IV.
    The majority draws in this portion of its opinion on the
    approach -- commonly referred to as the "categorical approach" --
    that the Court relied on in Moncrieffe to construe § 1101(a)(43).
    See 
    569 U.S. at 190-91
    . Under that approach, the critical question
    is whether a comparison of the elements of the generic, federal
    "obstruction    of    justice"-related      offense    referred    to   in
    § 1101(a)(43)(S) and the elements of the state-law accessorial
    offense of which Silva was convicted reveals that the least of the
    conduct criminalized by that accessorial offense is encompassed by
    the generic, federal offense. For, under the categorical approach,
    unless that comparison does reveal such a match arising from the
    elements of the two offenses, Silva's accessorial offense of
    conviction is not "an offense relating to obstruction of justice."
    - 62 -
    I have explained how the BIA defines the elements of the
    "offense   relating    to   obstruction    of   justice"     to   which
    § 1101(a)(43)(S) refers.     There remains to address, then, only
    whether that offense -- so understood -- encompasses the least of
    the conduct encompassed by the elements of the Massachusetts
    accessory-after-the-fact offense of which Silva was convicted.
    That accessorial offense contains the following four
    elements: that the defendant (1) "harbors, conceals, maintains, or
    assists the principal felon or accessory before the fact, or gives
    such offender any other aid," (2) does so "after the commission of
    a felony," (3) does so "knowing that [the person being assisted]
    has committed a felony or has been accessory thereto before the
    fact," and (4) does so with the specific intent that the defendant
    "avoid or escape arrest, detention, trial, or punishment."        
    Mass. Gen. Laws ch. 274, § 4
    ; see also Commonwealth v. Watson, 
    165 N.E.3d 1015
    , 1025 (Mass. 2021); Commonwealth v. Iacoviello, 
    58 N.E.3d 1032
    , 1047 (Mass. App. Ct. 2016); Commonwealth v. Clipp, No. 10-
    0296, 
    2011 WL 5182244
    , at *2 (Mass. Super. Ct. Aug. 26, 2011).
    None of the elements purports on its face to require that an
    official   judicial   proceeding   or   investigation   be   reasonably
    foreseeable -- let alone pending -- at the time of the alleged
    accessorial conduct by the defendant. Nor, as I will next explain,
    may any of them be read impliedly to so require.
    - 63 -
    A.
    The   first   element      (though     I   suppose       it    could   be
    understood to be a compendium of elements in its own right) defines
    part of the actus reus of the offense.                    It provides that the
    government must prove that the defendant engaged in conduct that
    could   qualify     as     obstructive        conduct     of     the       kind   that
    § 1101(a)(43)(S) encompasses.
    But, nothing in the element requires there to be proof
    of a linkage of any kind between that conduct and an official
    investigation or proceeding into any crime.                    Thus, this element
    cannot ensure the required categorical match between the two
    offenses.     Nor does the BIA -- or, for that matter, the majority
    -- suggest otherwise.
    B.
    The second element requires proof that the recipient of
    the defendant's aid committed a felony or was an accessory before
    the fact to that felony.          This element also defines part of the
    actus reus of the offense.            But, it requires no more of a showing
    than that the defendant lent the requisite type of aid to the
    recipient of it after that recipient had in fact committed a felony
    or been an accessory before the fact to it.               Thus, it would appear
    that, just like the first element, this element also does not on
    its   face   require     proof   of    what   the   BIA    by   its    own    account
    understands the generic, federal "obstruction of justice"-related
    - 64 -
    offense   to    demand:   proof   that   an   official   investigation   is
    reasonably foreseeable at the time of the obstructive conduct and
    thus that there is a nexus of at least that sort between the
    defendant's obstructive conduct and an official investigation.
    In    addition,    the    accessorial    offense    cannot    be
    understood to be impliedly subject to a "reasonably foreseeable"-
    based nexus requirement as an element, because it applies to being
    an accessory after the fact to Massachusetts felonies that are in
    their nature no more likely to be detected than the offense at
    issue in Marinello.       See, e.g., Mass. Gen. Laws ch. 62C, § 73(a)-
    (b), (f) (defining several tax-related felonies, such as the
    willful evasion of or "failure to collect or truthfully account"
    for a tax); id. ch. 266, § 67C (making it a felony to knowingly
    and willfully make a false entry in a book or record of a public
    contract); id. § 111C (making certain variations of insurance
    fraud a felony); id. ch. 267, § 8 (making it a felony to counterfeit
    certain bank bills); id. ch. 267A, § 2 (making it a felony to
    launder any amount of money or property); id. ch. 271, § 49(a)
    (making it a felony to charge more than twenty percent annual
    interest on a loan).        See generally id. ch. 274, § 1 (defining
    felonies to include any crime punishable by "imprisonment in the
    state prison").     Indeed, one of the tax-related felonies in Mass.
    Gen. Laws ch. 62C, § 73, such as willfully evading a tax or
    concealing goods on which a tax is to be imposed, seems to me to
    - 65 -
    be the same as the offense at issue in Marinello, as there is no
    reason to presume from the fact that such an offense has been
    committed more than that authorities "may eventually catch on" to
    the commission of that offense.
    The only potential complication that I can see with this
    conclusion is that the underlying "felony" in Silva's case is
    murder, which as a general matter is a crime more likely to trigger
    an investigation upon its occurrence than a tax offense.                           But,
    Silva   asserts,      without   dispute     from     the    government       or     the
    expression of any contrary view by the BIA, that the Massachusetts
    accessory-after-the-fact statute is not divisible.                    Nor did the
    BIA suggest here that Silva's offense of conviction qualifies as
    "an offense relating to obstruction of justice" because of the
    nature of the predicate felony that the principal committed.
    C.
    The third element does require proof that the defendant
    accused   of    the   accessorial    conduct     lent      aid   to   the   one    who
    committed the felony or was an accessory before the fact to it
    "knowing that [the person being assisted] ha[d] committed a felony
    or has been accessory thereto before the fact."                  
    Mass. Gen. Laws ch. 274, § 4
    .      But, proof of such knowledge -- which is all that
    this element requires -- cannot demonstrate the kind of nexus that
    the   BIA's    Marinello-based      "in   the    offing"     standard       requires
    between   obstructive      conduct    and       an   investigation:         that    an
    - 66 -
    investigation into that felony was in fact reasonably foreseeable
    at the time of the accessorial conduct.    Nor did the BIA suggest
    that, given the principal's predicate crime in Silva's case, proof
    of such a nexus was necessarily required to convict Silva of this
    accessorial crime.
    D.
    That leaves the fourth element, which requires proof
    that the defendant engaged in the alleged accessorial conduct "with
    intent that [the principal or accessory before the fact] shall
    avoid or escape detention, arrest, trial or punishment," 
    Mass. Gen. Laws ch. 274, § 4
    .   The majority rightly notes that "[a]bsent
    an investigation, there can be no prosecution and no detention,
    arrest, trial, or punishment to avoid or escape."   Maj. Op. at 28.
    But, this element does not require proof that detention, arrest,
    trial or punishment is reasonably foreseeable.      Rather, it is a
    classic mens rea element that does not concern the actus reus at
    all.
    Nor does the element require proof -- as a means of
    proving the defendant's mental state -- that an investigation was
    in fact in the offing (or, for that matter, was even reasonably
    foreseeable under any understanding of that constraint).        The
    element requires proof merely that the defendant lent certain kinds
    of aid to the one who committed a felony or was an accessory before
    the fact to that felony with the intent to help that recipient
    - 67 -
    evade arrest, trial, punishment, or detention.          See Watson, 165
    N.E.3d at 1025.
    In   fact,   it   appears   that   under   this   Massachusetts
    offense the defendant need not even have been shown to have
    reasonably but mistakenly believed that an official investigation
    was in the offing when he lent such aid.       It instead appears that
    he need only be shown to have subjectively believed -- even if
    unreasonably -- that such an investigation was in the offing when
    he did so. Cf. Commonwealth v. Liebenow, 
    20 N.E.3d 242
    , 250 (Mass.
    2014) (holding that a defendant's honest but unreasonable belief
    that property was abandoned was sufficient to establish a defense
    that turned on that honest belief); Commonwealth v. Lahens, 
    177 N.E.3d 935
    , 942 (Mass. App. Ct. 2021) ("Specific intent crimes are
    commonly identified by the presence of a subjective intent to cause
    a result that is separate from the crime's actus reus." (citing 1
    W.R. LaFave, Substantive Criminal Law § 5.2(e) (3d ed. 2018)));
    Commonwealth v. Cachopa, No. 09-P-2337, 
    2014 WL 5461490
    , at *2
    (Mass. App. Ct. Oct. 29, 2014) (inquiring into the defendant's
    state of mind to determine if evidence was sufficient to support
    a conviction under the accessory after the fact statute); Clipp,
    
    2011 WL 5182244
    , at *2 (same for an indictment).
    Proof of no more than that the defendant held a belief
    (and not necessarily even an objectively reasonable one) about the
    investigation being reasonably foreseeable as of the time of his
    - 68 -
    accessorial      conduct     is    not   proof    of   the   investigation   being
    reasonably foreseeable in fact as of that time.                 As such, proof of
    that sort is not proof of what the BIA -- and thus the majority --
    agrees the generic, federal offense in § 1101(a)(43)(S) requires.
    See Uppal v. Holder, 
    605 F.3d 712
    , 718 (9th Cir. 2010) (finding a
    Canadian criminal offense not to be a categorical match to a crime
    involving moral turpitude because the Canadian statute "require[d]
    only    that    the   risk    of    harm   resulting     from   the   assault   be
    'objective[ly] fores[eeable],'" while the relevant crime of moral
    turpitude required "subjective knowledge of a factor indicating
    risk to another").
    To be sure, in finding here that the Massachusetts
    accessorial offense at issue is a categorical match for the
    generic, federal offense referred to in § 1101(a)(43)(S), the BIA
    does rely on this fourth element and does state that "[t]here would
    be little reason for a defendant to be an accessory after the fact
    in this manner unless an investigation or proceedings [sic] was
    reasonably foreseeable" (internal quotation marks omitted).30 But,
    the BIA ignores the obvious point that a defendant can have an
    intention to lend aid for such a purpose without there being any
    proof that, in fact, the purpose could be accomplished. Cf. United
    The Fourth Circuit also rested its decision on a similar
    30
    specific intent element in interpreting a Virginia statute. Pugin,
    19 F.4th at 454.
    - 69 -
    States v. Zhen Zhou Wu, 
    711 F.3d 1
    , 18 (1st Cir. 2013) ("[E]ven
    where the evidence is sufficient to show the necessary mens rea,
    the government still must always 'meet its burden of proving the
    actus reus of the offense.'" (quoting United States v. Whiteside,
    
    285 F.3d 1345
    , 1353 (11th Cir. 2002))).
    One need only consider the case in which the felon tells
    the accessory that he, the felon, is sure to be arrested as a means
    of inducing the accessory to lend assistance.           If, in fact, there
    is no evidence to show that it was reasonably foreseeable at the
    time the assistance was provided by the accessory that authorities
    would investigate the felon's unlawful conduct -- and there was
    instead at most evidence at that time that authorities "may" do so
    "eventually" -- the BIA's own articulated standard for proving the
    nexus would not be met even though the specific intent requirement
    of the Massachusetts accessory-after-the-fact offense would be
    satisfied.     Cf., e.g., United States v. De Leon, 
    270 F.3d 90
    , 92
    (1st Cir. 2001) (recognizing that an offense "is a specific intent
    crime" because it "requires a subjective intent" to achieve a
    specific end); Cachopa, 
    2014 WL 5461490
    , at *2; Clipp, 
    2011 WL 5182244
    , at *2.
    E.
    In    sum,   careful   attention   to   the    elements   of   the
    Massachusetts accessorial offense of which Silva was convicted and
    the elements of the generic, federal "obstruction of justice"-
    - 70 -
    related offense referred to in § 1101(a)(43)(S) -- as described by
    the BIA -- shows that the two offenses (so understood) are not a
    categorical match.        And that is so, even if the generic, federal
    offense requires no more of a nexus between the defendant's
    obstructive conduct and an investigation or proceeding than the
    BIA   has    determined    that   offense      to    require,     given   both   the
    Marinello-informed        "in   the   offing"       gloss    on   the   "reasonably
    foreseeable" standard that the BIA holds defines that offense's
    nexus      requirement    and   the   fact   that     this    nexus     requirement
    constrains the actus reus of that offense.              Thus, there is no basis
    for us to uphold the BIA's conclusion that Silva's offense of
    conviction is a categorical match for it.31
    V.
    The majority contends that I am mistaken in reaching
    this conclusion.          It does so in part by emphasizing that in
    applying the categorical approach we may not imagine "fanciful,
    hypothetical scenarios."          United States v. Fish, 
    758 F.3d 1
    , 6
    (1st Cir. 2014) (citing Gonzales v. Duenas-Alvarez, 
    549 U.S. 183
    ,
    193 (2007)); see also United States v. Starks, 
    861 F.3d 306
    , 315
    (1st Cir. 2017).     The majority points in this regard to the absence
    of any reported cases in Massachusetts of prosecutions for the
    The "relating to" words in § 1101(a)(43)(S) still retain a
    31
    function: they pick up inchoate versions of an offense that is for
    "obstruction of justice."
    - 71 -
    accessory after the fact offense that is at issue in circumstances
    in which the defendant's obstructive conduct did not have a nexus
    to a reasonably foreseeable investigation or proceeding.
    But, the categorical approach has never been understood
    to make the test of a state law's legally operative scope wholly
    dependent on the presence of reported cases of actual prosecutions
    for such conduct, in part because reported cases may not be
    representative of charging practices.    Da Graca v. Garland, 
    23 F.4th 106
    , 113-14 (1st Cir. 2022); Swaby v. Yates, 
    847 F.3d 62
    ,
    65-66 (1st Cir. 2017) (noting that the Duenas-Alvarez limitation
    "has no relevance" to a case where the text of a state law clearly
    prohibited certain conduct but the petitioner "had failed to show
    that there was a realistic probability that [the state] would
    actually prosecute offenses" derived from that conduct). Nor would
    such a test make sense.
    The outcome under the categorical approach depends on
    what the statute setting forth the offense at issue is fairly read
    to require the government to prove.     It does not depend on how
    aggressively prosecutors choose to enforce that offense or the
    actual conduct of defendants in committing it.     See Swaby, 847
    F.3d at 65-66.32
    32 For this reason, the majority's point that "Silva's plea
    leaves no doubt that he intended to obstruct a reasonably
    foreseeable investigation," Maj. Op. at 5 n.2, is irrelevant to
    - 72 -
    I agree that we may not stretch the text of a criminal
    statute to cover conduct that we have no good reason to conclude
    that the statute in fact reaches.       But, we must construe such a
    statute to reach the conduct that its text plainly does reach.
    And, that is so regardless of whether any case involving such
    conduct has been prosecuted and then resulted in a published
    opinion.    See United States v. Burghardt, 
    939 F.3d 397
    , 409 (1st
    Cir. 2019) (reaffirming that we should "avoid treating the state
    offense as if it is narrower than it plainly is." (internal
    quotation marks and alterations omitted) (quoting Swaby, 847 F.3d
    at 66)).
    Thus, what matters here is what is clear from the text
    of the state-law statute that sets forth the accessorial offense
    at issue.    And, what is clear from that text is both that the
    offense may be committed under Massachusetts law with respect to
    tax evasion and that the state may prove the commission of that
    accessorial offense in relation to that type of felony without
    proving that any investigation into that felony was "in the
    this case. The categorical approach demands that "we look 'not to
    the facts of the particular prior case,' but instead to whether
    'the state statute defining the crime of conviction' categorically
    fits within the 'generic' federal definition of a corresponding
    aggravated felony." Moncrieffe, 
    569 U.S. at 190
     (quoting Duenas-
    Alvarez, 
    549 U.S. at 186
    ). A defendant's plea in an individual
    case cannot define the elements of a state law offense to be other
    than what the statutory text that sets forth that offense -- and
    the state's highest court's interpretation of it -- defines those
    elements to be.
    - 73 -
    offing."    Thus, it is clear that there is no requirement to prove
    a nexus of the "in the offing"-constrained sort that the BIA has
    determined must be proved as part of the actus reus of an "offense
    relating to obstruction of justice."
    The majority does attempt to respond to this line of
    argument.    It does so by asserting that the state law accessorial
    offense at issue here is a categorical match for the "obstruction
    of justice"-related offense referred to in § 1101(a)(43)(S) only
    so long as the underlying "felony" for that accessorial offense is
    one that the majority understands to be a "serious" felony.                The
    majority then goes on to hold that the accessorial offense of which
    Silva was convicted is such a categorical match precisely because
    Silva was convicted of being an accessory after the fact to such
    a "serious" felony -- namely, murder.
    But, no party to the case or the BIA has indicated that
    the   accessorial   offense   at   issue    either   is   divisible   or    is
    indivisible but, contrary to its plain text, has an implicit
    "seriousness" limitation that makes it just fine to be an accessory
    after the fact to a tax crime.       Nor is the accessorial offense in
    Silva's case one for which the BIA's "reasonably foreseeable"-
    based nexus had to be proved as part of its actus reus.          I thus do
    not understand how the basis on which the majority purports to be
    explaining away Marinello's significance to this case -- which, I
    note, is not the bass on which the BIA itself relied -- comports
    - 74 -
    with the categorical approach to which the majority purports to be
    faithful.
    I would add only in this connection that the "traditional
    concept"    of   accessory    after    the     fact     offenses   is    that   "the
    accessory's liability derives from that of his principal."                      Model
    Penal Code § 242.3 (Am. L. Inst. 1985); see also 5 Tucker's
    Blackstone *35 (defining an accessory as "he who is not the chief
    actor in the offense . . . but is someway concerned therein").
    For that reason, there was no need at common law to require proof
    for such a crime that the aid to the felon that the accessory
    provided in fact interfered with an investigation that was "in the
    offing."    It was enough to require proof that the accessory shared
    some culpability for the principal's crime, which could be proved
    through evidence of his culpable mental state at the time that he
    lent the aid.
    By   contrast,    offenses       of   the    kind   that    Blackstone
    labeled as ones against "public justice" -- which are the kinds of
    offenses    that   we   now   usually    call     "obstruction      of    justice"
    offenses, see Maldonado v. Commonwealth, 
    829 S.E.2d 570
    , 575 (Va.
    Ct. App. 2019) (looking to Blackstone's list of offenses against
    public justice to determine the meaning of obstruction of justice
    at common law); People v. Jenkins, 
    624 N.W.2d 457
    , 465 (Mich. Ct.
    App. 2000) (same) -- were different.              The criminal liability of
    the one who committed the offense against public justice was
    - 75 -
    understood to be derived from his conduct as a principal in his
    own right based on his having done something criminal in and of
    itself -- impeding the administration of justice.                     See, e.g.,
    5 Tucker's Blackstone *127-41; Wharton's Criminal Law §§ 562, 570
    (15th ed. 1996).
    As a result, it is not "fanciful" to conclude that
    Silva's offense of conviction requires no proof of the kind of
    nexus     between   obstructive       conduct     and   an    investigation       or
    proceeding that the majority and the BIA acknowledge Congress did
    require for the generic, federal "obstruction of justice"-related
    offense    referred       to   in    § 1101(a)(43)(S).         Rather,    such    a
    construction of Silva's offense of conviction merely results in
    that offense being different from an "obstruction of justice"
    offense in a way that even Blackstone would recognize.                5 Tucker's
    Blackstone      *37-39,    *127-41    (treating    those     types   of   offenses
    separately in distinct chapters of his treatise).
    The majority separately takes issue with my invocation
    of Marinello, to the extent that I take the view that the BIA
    relied     on    Marinello's         understanding      of    the    "reasonably
    foreseeable" standard to define the required nexus for an "offense
    relating to obstruction of justice" under § 1101(a)(43)(S).                      The
    majority focuses in doing so on the fact -- which I do not dispute
    -- that the Court there did not have occasion to decide whether
    the evidence in that specific case could suffice to satisfy the
    - 76 -
    "in the offing"-based nexus requirement that the Court there
    described.
    But, as I have already explained, proof of the commission
    of a predicate crime -- or the awareness of its commission by the
    one guilty of the accessorial offense -- is not proof that an
    investigation into that predicate crime was in fact reasonably
    foreseeable at the time of the accessorial conduct in the "in the
    offing" sense.   It is at most proof that authorities "may" (or of
    the defendant's knowledge that the authorities may) "eventually"
    catch on to that predicate crime's commission.             But, that is
    exactly the sort of proof that Marinello clearly deemed inadequate
    to satisfy the "reasonably foreseeable" standard that the Court
    described in that case.
    Thus, because the state law accessorial offense of which
    Silva was convicted requires, as to its actus reus, no more than
    proof of the defendant's mere awareness of the predicate crime's
    commission -- which, as best I can tell, is also a point that the
    majority does not dispute -- that state law accessorial offense
    cannot be a categorical match for the "obstruction of justice"-
    related offense set forth in § 1101(a)(43)(S) as the BIA has
    described that offense's elements.        For, while the BIA does point
    to the specific intent element of the Massachusetts accessory-
    after-the-fact   offense   in   concluding    otherwise,   the   majority
    overlooks the way that the BIA itself defines the actus reus of an
    - 77 -
    "offense relating to obstruction of justice" and so mixes up actus
    reus and mens rea elements in a way that the elements-based
    categorical approach simply does not permit.
    VI.
    I have explained before why I do not agree with the
    criticism    that    the    categorical     approach   permits   technical
    inquiries to yield the conclusion that objectively concerning
    criminal conduct is of no concern to the Congress that enacted the
    measure that imposes the special, adverse consequence at issue.
    See United States v. Faust, 
    853 F.3d 39
    , 61-66 (1st Cir. 2017)
    (Barron,    J.,   concurring).      But,    the   objection   that   such   a
    technical, elements-based inquiry misses the forest for the trees
    is especially misplaced here, given the history that I have just
    recounted    about   how    accessorial     offenses   historically     were
    understood to be conceptually distinct from offenses for impeding
    the   administration       of   public   justice.      And,   indeed,   the
    organization of modern criminal codes still reflects such an
    understanding of those two types of offenses being distinct.            See,
    e.g., 
    18 U.S.C. § 3
    , ch. 73; Mass. Gen. Laws ch. 268, ch. 274,
    § 4; cf. Da Graca, 23 F.4th at 112 (determining the scope of a
    state criminal statute in part by looking to certain of the state's
    other criminal statutes, and approvingly noting that the BIA
    "interpreted the existence of a separate California joyriding
    statute to cabin the breadth of the California unauthorized use
    - 78 -
    [of a motor vehicle] statute").    Thus, if history is our guide,
    there is quite good reason to think that the Congress that singled
    out offenses "relating to obstruction of justice" -- even accepting
    as the majority does that the BIA is right in how expansively it
    has defined that category of offenses -- was not a Congress that
    had in view the kind of accessorial crime of which Silva was
    convicted.
    I do not mean to suggest that anything would prevent a
    state from defining the elements of an offense that it labels as
    an accessorial one in a way that would make that offense a match
    for "an offense relating to obstruction of justice," as the BIA
    understands that offense.    But, as I have explained, there is no
    indication that Massachusetts has done so here.
    Accordingly,   I   conclude   that   although   Silva   was
    convicted of being an accessory after the fact to a felony, neither
    the BIA nor the majority has established that he has been convicted
    of an "offense relating to obstruction of justice," such that he
    may be deemed to have committed an "aggravated felony" within the
    meaning of the INA.   I therefore would grant Silva's petition for
    review and so, respectfully, dissent.
