    SUMMARY*
    Habeas Corpus
    The panel reversed the district court’s denial of federal
    prisoner Daniel Alejandro Zavala’s 28 U.S.C. § 2241 habeas
    corpus petition claiming improper denial of sentencing credit,
    and remanded.
    The panel held that when immigration officials detain an
    alien pending potential prosecution, the alien is entitled under
    18 U.S.C. § 3585(b) to credit toward his criminal sentence;
    that an alien is entitled to credit for all time spent in
    Immigration and Customs Enforcement Agency detention
    subsequent to his indictment or the filing of formal criminal
    charges against him; and that where a factual dispute exists,
    the district court must hold an evidentiary hearing as to
    whether an alien’s detention by ICE prior to the date of his
    indictment or the filing of criminal charges against him
    constituted detention pending prosecution.
    The panel held that the district court erred when it denied
    Zavala sentencing credit for the post-indictment period during
    which ICE detained him pending criminal prosecution. The
    panel remanded for the district court to determine in the first
    instance whether and when during the pre-indictment period
    Zavala’s detention status changed from detention pending
    deportation to detention pending potential prosecution. The
    panel held that, on remand, the government has the burden of

    proving that the pre-indictment detention was for the purpose
    of deportation rather than potential prosecution.
    Concurring in part and dissenting in part, Judge Callahan
    agreed with the majority that under § 3585(b) an alien is
    eligible for credit for all time spent in ICE custody from the
    day he or she is indicted or criminally charged. She dissented
    from the majority’s broader interpretation of § 3585 – that an
    alien is entitled to credit toward his criminal sentence for the
    period during which ICE detained the alien pending potential
    criminal prosecution.

    OPINION
    REINHARDT, Circuit Judge:
    Daniel Zavala seeks credit toward his criminal sentence
    under 18 U.S.C. § 3585(b), the sentencing credit statute, for
    two periods of time during which he was detained by the U.S.
    Immigration and Customs Enforcement Service (ICE) prior
    to the commencement of his criminal sentence for illegal
    reentry under 8 U.S.C. § 1326. We hold that where ICE
    detains an alien pending potential criminal prosecution, that
    detention constitutes “official detention” within the meaning
    of § 3585(b) and the alien is accordingly entitled to credit
    toward his criminal sentence.
    I.
    On September 20, 2010, Zavala was transferred from state
    custody, where he had finished serving a state criminal
    sentence, into the custody of ICE. That same day, an ICE
    officer gave him a Form I-871, U.S. Department of Homeland
    Security Notice of Intent/Decision to Reinstate Prior Order,
    which Zavala signed.1 The I-871 Form provided that ICE had
    determined that Zavala was subject to a prior order of
    removal entered on May 2, 2006, that he had previously been
    removed on May 3, 2006 pursuant to an order of removal,
    and that he illegally reentered the United States on or about
    July 14, 2009. Zavala signed the “Acknowledgment and
    1
    We grant Zavala’s unopposed motion to take judicial notice of the
    September 20, 2010 Form I-871 and the Record of Sworn Statement in
    Affidavit Form dated September 20, 2010, both of which documents were
    in Zavala’s immigration file and were provided to him by the Government
    in these proceedings.
    ZAVALA V. IVES                               5
    Response” section of the I-871 Form stating “I do not wish to
    make a statement contesting this determination.”2 The ICE
    officer accordingly reinstated the prior order of removal by
    signing the “Decision, Order, and Officer’s Certification”
    section of Form I-871, which stated that “[h]aving reviewed
    all available evidence, the administrative file and any
    statements made or submitted in rebuttal, I have determined
    that the above-named alien is subject to removal through
    reinstatement of the prior order, in accordance with section
    241(a)(5) of the [Immigration and Nationality] Act.”
    Although reinstatement of the prior order allowed ICE to
    remove Zavala from the country at any time from September
    20, 2010 onward, ICE nonetheless continued to detain Zavala
    until October 6, 2010—sixteen days later.
    On October 6, 2010, a grand jury in the District of
    Nevada returned an indictment charging Zavala with illegal
    reentry under § 1326. ICE then transferred Zavala into the
    custody of the United States Marshals Service (USMS), and
    Zavala was in USMS custody as of October 7, 2010.
    Sixty-two days later, on December 7, 2010, the United States
    District Court for the District of Nevada granted the
    Government leave to dismiss the unlawful reentry charge due
    to improper venue.
    On December 10, 2010, following dismissal of the
    indictment for improper venue, Zavala was transferred from
    USMS custody back into ICE custody. Twelve days later, on
    2
    Also on September 20, 2010, Zavala completed and signed an affidavit
    on a form provided by ICE admitting that he was a citizen of Mexico, that
    he had previously been deported, that he reentered the United States on
    foot from Mexico, and that he had not sought permission to reenter the
    United States.
    6                          ZAVALA V. IVES
    December 22, 2010, a criminal action for illegal reentry under
    § 1326 was again brought against Zavala, this time in the
    Central District of California, the proper venue, and he was
    again transferred into USMS custody from ICE custody.
    Pursuant to a plea agreement, Zavala was sentenced on
    March 28, 2011 to 46-months’ imprisonment and 3-years’
    supervised release for illegal reentry under § 1326(a). In
    calculating Zavala’s entitlement to sentencing credit under
    § 3585(b) for time he spent in detention prior to the
    commencement of his criminal sentence, the Bureau of
    Prisons (BOP) granted Zavala credit for the two periods of
    time during which USMS detained him—October 6, 2010
    through December 10, 2010, and December 22, 2010 through
    March 27, 2011.3
    BOP denied Zavala sentencing credit, however, for the
    two periods of time during which ICE detained him prior to
    the commencement of his criminal sentence: (1) September
    20, 2010 through October 5, 2010, when ICE detained him
    after reinstatement of the removal order but before an
    indictment was returned, hereinafter referred to as the “pre-
    indictment period”; and (2) December 11, 2010 through
    December 21, 2010, when ICE detained him between the
    dismissal of the first indictment for improper venue and the
    re-initiation of the criminal proceeding in the proper venue,
    hereinafter referred to as the “post-indictment period.”
    3
    BOP, rather than the sentencing court, calculates the defendant’s
    entitlement to sentencing credit under § 3585(b) in the first instance. See
    United States v. Wilson, 
    503 U.S. 329
    , 335 (1992). A defendant may then
    challenge BOP’s calculation—in other words, the execution of the
    sentence—by filing a petition for a writ of habeas corpus under 28 U.S.C.
    § 2241. See United States v. Giddings, 
    740 F.2d 770
    , 772 (9th Cir. 1984).
    ZAVALA V. IVES                        7
    On May 20, 2013, Zavala filed a petition for a writ of
    habeas corpus pursuant to 28 U.S.C. § 2241, claiming
    improper denial of sentencing credit because he had “been in
    official custody of the federal government since September
    20, 2010.” A magistrate denied sentencing credit for both
    periods of detention by ICE, and the district court adopted in
    full the magistrate’s report and recommendation. Zavala
    appealed.
    II.
    Zavala contends that the district court erred in concluding
    that detention by immigration authorities never constitutes
    “official detention” within the meaning of § 3585(b), the
    statute governing the calculation of a term of imprisonment.
    We review the district court’s denial of a habeas petition de
    novo, while we review any underlying factual findings for
    clear error. Reynolds v. Thomas, 
    603 F.3d 1144
    , 1148 (9th
    Cir. 2010), abrogated on other grounds by Setser v. United
    States, 
    132 S. Ct. 1463
    (2012). We review questions of
    statutory interpretation de novo. United States v. Thompson,
    
    728 F.3d 1011
    , 1015 (9th Cir. 2013); Phoenix Mem’l Hosp.
    v. Sebelius, 
    622 F.3d 1219
    , 1224 (9th Cir. 2010).
    A.
    Title 18 U.S.C. § 3585 governs the calculation of the
    length of a federal criminal sentence. Under the statute, a
    term of imprisonment begins “on the date the defendant is
    received in custody awaiting transportation to, or arrives
    voluntarily to commence service of sentence at, the official
    detention facility at which the sentence is to be served.”
    § 3585(a). The statute then provides that the defendant is
    entitled to sentencing credit for time spent in “official
    8                      ZAVALA V. IVES
    detention” prior to the commencement of the term of
    imprisonment:
    Credit for prior custody.—A defendant shall
    be given credit toward the service of a term of
    imprisonment for any time he has spent in
    official detention prior to the date the sentence
    commences—
    (1) as a result of the offense for which the
    sentence was imposed; or
    (2) as a result of any other charge for which
    the defendant was arrested after the
    commission of the offense for which the
    sentence was imposed;
    that has not been credited against another
    sentence.
    § 3585(b). The statute does not define “official detention.”
    When interpreting a statute, “[w]e start, as always, with
    the language of the statute.” Williams v. Taylor, 
    529 U.S. 420
    ,
    431 (2000). In so doing, “[w]e give the words of a statute
    their ‘ordinary, contemporary, common meaning,’ absent an
    indication Congress intended them to bear some different
    import.” 
    Id. Under the
    plain text of the sentencing credit
    statute, when ICE detains an alien for the purpose of securing
    his presence at a potential criminal prosecution and the alien
    is indeed criminally prosecuted and sentenced, this period of
    detention by ICE is “as a result of the offense for which the
    sentence was imposed.” § 3585(b)(1). The “as a result of”
    formulation denotes a causal relationship. When ICE detains
    ZAVALA V. IVES                               9
    an alien pending a potential criminal prosecution, electing to
    defer deportation until the conclusion of such criminal
    proceedings (and often until after service of the criminal
    sentence), that period of ICE detention is causally attributable
    to the criminal offense rather than to ICE’s authority to detain
    an alien pending deportation. Under the plain meaning of the
    words, detention is the holding of aliens in custody (which
    the immigration statutes expressly describe as “detention”),4
    and ICE is without question an official entity. Pending
    prosecution means the time during which the alien is detained
    for the purpose of securing his presence at a potential
    criminal prosecution, whereas pending deportation means
    detention for the purpose of removing him from the country.
    The legislative history of § 3585 does not shed any
    additional light on whether ICE detention pending criminal
    prosecution constitutes “official detention,” but similarly it
    does not contain any indication that Congress intended the
    statute’s words to have a different import than their plain
    meaning.5 Thus, we conclude that the relevant inquiry to
    4
    8 U.S.C. §§ 1226(a)(1); 1231(a)(2).
    5
    Early versions of the Sentencing Reform Act of 1984, which rewrote
    and recodified the sentencing credit statute, creating § 3585, included a
    definition of “official detention” that encompassed “detention by a public
    servant . . . pending deportation”—a far more expansive definition than
    the one we adopt. See, e.g., Criminal Code Reform Act of 1981, S. 1630,
    97th Cong. § 111 (1981). The entirety of the definitions section, however,
    was deleted prior to enactment.
    In United States v. Wilson, the Supreme Court held that the deletion
    of a reference to the Attorney General during the recodification of the
    sentencing credit statute effected no change in the statute’s meaning. 
    See 503 U.S. at 336
    (concluding the reference “was simply lost in the
    shuffle”). The Court noted that Congress’s replacement of the term
    10                         ZAVALA V. IVES
    determine whether a period of ICE detention constituted
    “official detention . . . as a result of the offense for which the
    sentence was imposed” is whether the detainee was being
    held pending a potential criminal prosecution, rather than
    pending deportation in the ordinary course—that is, whether
    the alien’s detention status had changed from pending
    deportation, which it was at the time he was first detained, to
    pending prosecution.
    A number of considerations support our interpretation of
    the statute as having the meaning its plain words afford it.
    First, issues of sentencing credit arise only in cases in which
    the alien has in fact been criminally prosecuted and
    convicted, so the scope of our holding is necessarily
    circumscribed. In such cases, we always know that the
    government elected to pursue criminal prosecution, rather
    than to attempt to deport the alien forthwith. Otherwise, there
    would be no criminal sentence to credit. The only question is
    when the alien’s detention status changed from detention
    pending deportation to detention pending potential
    prosecution.
    Second, federal immigration officers and federal
    prosecutors work together closely to facilitate criminal
    prosecutions of aliens. See 8 U.S.C. § 1226(d)(1) (requiring
    cooperation between the Attorney General and federal, state,
    and local authorities “with respect to the arrest, conviction,
    and release of any alien charged with an aggravated felony”);
    United States Customs and Border Protection Inspector’s
    “custody” with “official detention” might have constituted a meaningful
    change, 
    id. at 337,
    but it subsequently held that the change was a technical
    one that did not alter the meaning of the statute. See Reno v. Koray,
    
    515 U.S. 50
    , 59–60 (1995).
    ZAVALA V. IVES                         11
    Field Manual § 18.11 (2008) (providing detailed instructions
    to immigration officers regarding development of a case for
    criminal prosecution in cooperation with U.S. Attorneys);
    United States Immigration and Customs Enforcement
    Detention and Deportation Officer’s Field Manual § 14.8
    (2006) (providing instructions on preserving a case for
    criminal prosecution after reinstatement of removal). It is
    typically ICE’s referral of a case to a U.S. Attorney that
    prompts the filing of charges for an immigration-status
    offense, and it is ICE’s delay of deportation and delivery of
    the alien to the U.S. Attorney that enables criminal
    proceedings to occur. Indeed, the record in this case is
    illustrative of the fact that prosecutions for immigration-status
    crimes are a collaborative effort by immigration officers and
    prosecutors: the only evidence supporting the criminal
    complaint against Zavala filed in the Central District of
    California was an affidavit by an ICE deportation officer.
    Given that prosecutions for immigration-status crimes
    result from cooperative efforts between the two sets of
    officials, it would be arbitrary to afford sentencing credit
    when the government elects to hold a defendant in USMS
    detention while it builds its criminal case but not when the
    government elects to hold a defendant in ICE detention while
    it does so. Under the district court’s hardline rule that
    immigration detention never constitutes “official detention,”
    two identically situated defendants would serve sentences of
    differing lengths based solely on the federal government’s
    election of ICE rather than USMS detention pending potential
    criminal prosecution. Individuals in immigration detention,
    unlike those in USMS detention, could be subjected to
    lengthy periods of detention with no offsetting sentencing
    credit. Further underscoring the arbitrariness of a blanket rule
    denying sentencing credit any time aliens are in ICE
    12                         ZAVALA V. IVES
    detention is the fact that BOP itself has afforded credit to
    aliens held in state detention pending federal prosecution, see
    § 3585(b)(2); U.S. Dept. of Justice, Bureau of Prisons
    Program Statement No. 5880.28, 1-14A, 1-21 (Feb. 14,
    1997); Abpikar v. Lompoc Federal Bureau of Prisons, No.
    CV 12-00827 MMM, 
    2012 WL 3777156
    , at *2 (C.D. Cal.
    July 16, 2012), adopting report & recommendation, 
    2012 WL 3776499
    (C.D. Cal. Aug. 30, 2012), and ICE detention often
    occurs in a state facility. See, e.g., Galan-Paredes v. Hogsten,
    No. 1:CV-06-1730, 
    2007 WL 30329
    , *1 (M.D. Pa. Jan. 3,
    2007) (defendant held in county jail in ICE detention status).
    In other words, two individuals could receive different
    sentencing credit and thus serve different length sentences
    based solely on which agency was nominally in charge of
    their detention in the same facility.6
    B.
    The Government makes four arguments in support of its
    contention that a defendant is never entitled to sentencing
    credit for time spent in ICE detention: (1) that Supreme Court
    precedent interpreting § 3585(b) in the context of pretrial
    release under the Bail Reform Act controls the instant case;
    (2) that BOP’s interpretation of § 3585(b) precludes
    sentencing credit for any and all time spent in immigration
    detention; (3) that sentencing credit is inappropriate because
    deportation proceedings are classified as civil; and (4) that
    6
    The dissent’s approach, under which a person held in ICE detention
    pending criminal prosecution would receive credit only if criminal charges
    have already been filed perpetuates this arbitrary disparity. When police
    officers arrest a criminal suspect, sentencing credit begins at the time of
    arrest, rather than when formal charges are filed. See, e.g., BOP Program
    Statement 5880.28 at 1-21.
    ZAVALA V. IVES                             13
    requiring BOP to work with ICE to calculate sentences would
    be unworkable. We reject these arguments.
    The Government argues that Reno v. Koray, 
    515 U.S. 50
    (1995), controls the instant case, but Koray’s holding was far
    narrower. The question presented to the Court by the grant of
    certiorari was “whether a federal prisoner is entitled to credit
    against his sentence under § 3585(b) for time when he was
    ‘released’ on bail pursuant to the Bail Reform Act of 1984,”
    and the Court held that release on bail to a private community
    treatment center did not constitute “official detention.” 
    Id. at 54,
    65. Although the release on bail at issue in Koray
    included restrictive conditions, it was clear that under the
    terms of the Bail Reform Act the defendant was “released”
    from official detention to a private facility. 
    Id. at 59.
    In the
    instant case, it is equally clear that under the relevant statutes,
    detention by immigration officials constitutes “detention” and
    not “release.” See 8 U.S.C. §§ 1226(a)(1)–(2), 1231(a)(2).7
    Despite dicta to the effect that official detention meant
    detention in a facility under the control of BOP, 
    see 515 U.S. at 58
    , Koray had no occasion to address immigration
    detention, and it expressly declined to reach cases in which a
    7
    The dissent asserts that we adopt different definitions of “official
    detention” with respect to ICE detention and community treatment centers.
    Not so. To recapitulate: Koray held that a person released to a community
    treatment center is not detained. We hold that where a person is detained
    by ICE, § 3585(b) may apply. Certainly where a person is released on
    bond by ICE, it does not.
    Nor do we agree with the dissent’s contention that because the
    Immigration Nationality Act and the Sentencing Reform Act were created
    by different legislation, we should not presume that Congress intended for
    them to be construed harmoniously.
    14                         ZAVALA V. IVES
    defendant is held in detention in an official facility not
    operated or controlled by BOP. The Court expressly stated
    that “BOP often grants credit under § 3585(b) for time spent
    in state custody, even though the defendant was not subject
    to the control of BOP. These situations obviously are not
    governed by reference to a [Bail Reform Act] § 3142
    ‘release’ or ‘detention’ order. . . . [B]ecause the only question
    before us is whether a defendant is in ‘official detention’
    under § 3585(b) during the time he is ‘released’ on bail
    pursuant to the Bail Reform Act of 1984, we need not and do
    not rule here on the propriety of BOP’s decision to grant
    credit under § 3585(b) to a defendant who is denied bail
    pursuant to state law and held in the custody of state
    
    authorities.” 515 U.S. at 63
    n.5 (citation omitted).8 A fortiori,
    Koray did not determine that immigration detention must be
    under the control of BOP in order to constitute “official
    detention”; rather, it left open the question we now answer:
    whether detention by immigration officials can constitute
    8
    The dissent asserts that we make too much of the statements in Koray
    pertaining to credit for state detention and that “official detention” in
    § 3585(b) is in all circumstances limited to detention under the control of
    BOP, USMS, or the Attorney General of the United States because that is
    the detention referred to as “official detention” in § 3585(a) and other
    provisions of the Sentencing Reform Act—the enactment that included the
    Bail Reform Act. We conclude, however, that we must abide by the
    Supreme Court’s statement that “situations [in which “the defendant was
    not subject to the control of the BOP”] obviously are not governed by
    reference” to the Bail Reform Act. 
    Koray, 515 U.S. at 63
    n.5. (second
    emphasis added). It is equally obvious that such situations are not
    governed by reference to other provisions of the Sentencing Reform Act
    pertaining to inmates in federal prisons.
    ZAVALA V. IVES                             15
    “official detention.” We conclude that it can and that in this
    case it does.9
    Next, the Government argues that BOP’s Program
    Statement interpreting § 3585(b) precludes sentencing credit
    for all time spent in immigration custody, and that the
    Program Statement is entitled to deference. Congress
    delegated responsibility for the initial computation of
    sentences to the Attorney General, see United States v.
    Wilson, 
    503 U.S. 329
    , 333 (1992), who has in turn delegated
    that authority to BOP. See 28 C.F.R. § 0.96. We need not,
    however, reach the question of administrative deference.10
    9
    Even if Koray required a defendant to be under the control of BOP,
    USMS, or the Attorney General in all circumstances to be eligible for
    sentencing credit as the dissent contends, our colleague overlooks the
    dispositive fact that when Koray was decided in 1995 (and when BOP
    adopted its Program Statement), all immigration detainees—whether
    charged with a crime or not—were indeed within the control of the
    Attorney General. The Immigration and Nationality Service (INS) was in
    the Department of Justice and the Department had jurisdiction over
    immigration matters until 2002, when the Attorney General’s authority
    over immigration, including over the INS, was transferred to the Secretary
    of the newly formed Department of Homeland Security. See Establishment
    of Department; replacement of Immigration and Naturalization Service;
    transfer of functions, 3A Am. Jur. 2d Aliens and Citizens § 35 (George
    Blum et al. eds., 2015). Surely the transfer of INS to a new,
    comprehensive agency designed to cover national security matters did not
    change the nature of its control over immigration detention. Nor does it
    matter that INS was reorganized to be part of a newly created federal
    department reporting to the Secretary of Homeland Security, who
    exercises the authority over immigration matters that the Attorney General
    formerly did.
    10
    Under Tablada v. Thomas, the BOP Program Statement would be
    entitled to Skidmore, rather than Chevron, deference if it addressed the
    question presented. See 
    533 F.3d 800
    , 806 (9th Cir. 2008) (applying
    Skidmore deference to the interpretation of the good-time credit statute
    16                          ZAVALA V. IVES
    BOP’s Program Statement does not speak to situations in
    which ICE detains an alien pending criminal
    prosecution—potential or otherwise. The Government’s
    claim that the Program Statement establishes a blanket no-
    credit rule is thus incorrect.
    BOP Program Statement 5880.28 provides:
    Official detention does not include time spent
    in the custody of the U.S. Immigration and
    Naturalization Service (INS) under the
    provisions of 8 U.S.C. § 1252 pending a final
    contained in the same BOP Program Statement). Even if the BOP Program
    Statement precluded sentencing credit for any and all time spent in
    immigration detention, as the Government asserts, we would find this
    interpretation of the statute unpersuasive under Skidmore. When applying
    Skidmore deference, “[a]mong the factors we consider are the
    interpretation’s thoroughness, rational validity, consistency with prior and
    subsequent pronouncements, the logic and expertness of an agency
    decision, the care used in reaching the decision, as well as the formality
    of the process used.” 
    Id. (internal quotation
    marks and brackets omitted).
    The BOP Program Statement “does not purport to carry the force of law
    and was not adopted after notice and comment,” 
    id., and the
    closest it
    comes to giving any explanation for its interpretation of the statute is the
    inclusion of three case citations. See BOP Program Statement 5880.28 at
    1-15A. All three cases cited involved claims of constitutional error
    committed in the course of deportation proceedings and none of them
    involved sentencing credit. Rather, the cited cases simply denominate
    deportation proceedings as “civil” proceedings. See Ramirez-Osorio v.
    INS, 
    745 F.2d 937
    (5th Cir. 1984); Shoaee v. INS, 
    704 F.2d 1079
    (9th Cir.
    1983); Cabral-Avila v. INS, 
    589 F.2d 957
    (9th Cir. 1978). As discussed
    infra, that deportation proceedings are classified as civil has no bearing on
    whether a criminal defendant is entitled to credit toward his criminal
    sentence. Thus, even if the Government’s reading of the Program
    Statement were correct, it would lack the logic, expertise, and
    thoroughness needed to trigger deference to an agency’s interpretation of
    a statute.

    determination of deportability. An inmate
    being held by INS pending a civil deportation
    determination is not being held in “official
    detention” pending criminal charges.
    BOP Program Statement 5880.28 at 1-15A (emphasis added).
    By its text, the BOP Program Statement does not deny
    sentencing credit for any and all time an alien is held in
    immigration custody, as the Government contends. At best,
    it follows the same interpretation that we adopt: a line
    between detention pending deportation, for which a defendant
    is not entitled to sentencing credit, and detention pending
    criminal prosecution, including the filing of criminal charges,
    for which a defendant is entitled to sentencing credit.11 At
    worst, the Program Statement is silent as to whether a
    defendant is entitled to sentencing credit where ICE detains
    him pending potential criminal prosecution.12
    11
    The dissent proclaims that the phrase “pending criminal charges”
    refers solely to criminal cases in which charges have already been filed,
    as opposed to cases awaiting the filing of charges. This argument is
    without merit. In addition to the two definitions mentioned by the
    dissent—one of which is wholly consistent with our opinion—“pending”
    is also defined as “While awaiting; until” when used as a preposition.
    Black’s Law Dictionary (10th ed. 2014). See also Webster’s New World
    Dictionary 998 (3d Coll. ed. 1988) (including the following definitions:
    “not decided, determined, or established”; “about to happen; impending”;
    “throughout the course or process of”; and “while awaiting; until”). We
    decline to read into the Program Statement a distinction between cases in
    which charges have already been filed and those in which they are being
    explored, for the reasons previously discussed in Section 
    II.A, supra
    .
    12
    On at least four occasions reported in federal court decisions BOP has
    voluntarily granted sentencing credit for time the defendant spent in ICE
    detention where BOP determined that the detention was pending criminal
    prosecution and not pending deportation—including one case in which the
    detention preceded formal criminal charges. See Sanchez v. Kruger, No.

    Although a number of district courts have relied on the
    BOP Program Statement to deny sentencing credit for time
    during which a defendant was held in ICE detention pending
    deportation proceedings, we do not read these cases as
    inconsistent with our holding in any respect. First, they
    engage in only cursory analysis, stating merely that the BOP
    Program Statement is entitled to deference and that
    deportation proceedings are classified as civil. Second, these
    cases all refer to persons being held in custody pending
    deportation proceedings.13 Thus, these cases do not provide

    of securing his attendance at a criminal proceeding is entitled
    to such credit. Thus, the Government’s argument simply
    misses the point.
    The Government’s final argument is that requiring BOP
    to grant credit for time spent in ICE detention would be an
    unworkable regime because it would be “extremely difficult
    if not impossible to administer.” Zavala v. Ives, No. CV
    13-3603-JFW(E), 
    2013 WL 4763839
    , at *4 (C.D. Cal. Sept.
    3, 2013). We reject this argument, for two reasons.
    First, a number of district courts have already adopted the
    interpretation of § 3585(b) that we adopt today and granted
    credit for time spent in immigration detention pending
    potential prosecution, including pre-indictment periods as
    long as nearly two months.14 These courts engaged in a fact-
    based inquiry to determine when the defendant’s detention
    status changed from detention pending deportation to
    detention pending criminal prosecution. Courts are wholly
    competent to adjudicate when that status change occurred, as
    it is a factual inquiry that can often be resolved by examining
    ICE’s administrative records and the ICE officers responsible
    for an alien’s case. Indeed, BOP has at least on occasion
    voluntarily undertaken this inquiry itself. See supra note 12.
    Second, BOP already grants sentencing credit for time
    spent in state or foreign custody where that time was not
    credited to another sentence. See § 3585(b)(2); Koray,

    21 515 U.S. at 63
    n.5; BOP Program Statement 5880.28 at
    1-14A, 1-21. In order to facilitate the calculation of sentences
    in such circumstances, BOP has in place a policy for
    intergovernmental communications to investigate and verify
    claims of entitlement to sentencing credit. See BOP Program
    Statement 5880.28 at 1-26 (“Proper documentation will
    consist of written documentation . . . from any law
    enforcement agency (including probation officers). This
    includes verified phone, fax, or teletype messages, PSI, Rap
    Sheet, Booking Sheets, SENTRY, USM Form 129, etc.”). If
    anything, it should be easier, not harder, to coordinate an
    information exchange between two federal government
    actors—BOP and ICE—than it is to coordinate between state
    and federal or foreign and federal actors.15
    The fears that BOP and courts will be unable to
    administer a system that requires determining whether an
    alien’s detention constituted detention pending potential
    criminal prosecution, as opposed to detention pending
    deportation, are thus without merit. We are confident in
    BOP’s ability to comply with its statutory mandate with
    respect to detention by ICE—just as it does with respect to
    detention by state and foreign governments—and in the
    courts’ ability to adjudicate disputes over sentencing credit
    should they arise.
    15
    In fact, it may be markedly easier to determine eligibility for
    sentencing credit for ICE detention time than for state detention time, as
    the former situation does not present the double-counting problem present
    in the latter situation. See § 3585(b) (providing that a defendant may not
    receive credit against a federal sentence for detention time that has “been
    credited against another sentence”).
    22                     ZAVALA V. IVES
    III.
    For the forgoing reasons, we hold that an alien is entitled
    to credit toward his criminal sentence under § 3585(b) for the
    period during which ICE detained the alien pending potential
    criminal prosecution. We turn now to application of this
    principle to the facts of the instant case.
    A. Post-Indictment Detention
    ICE detained Zavala during the period of time after
    dismissal of the first indictment for improper venue and
    before the filing of identical criminal charges in the proper
    venue. This detention occurred from December 11, 2010
    through December 21, 2010. Zavala is clearly entitled to
    sentencing credit for this post-indictment period of ICE
    detention because it constituted detention pending criminal
    prosecution.
    Most important, this time period occurred after the
    Government instituted criminal charges. Where ICE retains
    an alien in custody subsequent to an indictment or the filing
    of criminal charges and the alien is then convicted of those
    charges, we hold that the intervening period of detention is
    presumed to be for the purpose of criminal prosecution and
    the alien is entitled to sentencing credit.
    The Government does not contend that during the post-
    indictment period ICE held Zavala pending deportation. The
    record makes clear that all governmental actors involved
    always intended that the criminal charges against Zavala be
    reinstated in the proper venue. The language of the
    Government’s proposed order of dismissal indicated its
    intention to refile criminal charges in the proper venue,
    ZAVALA V. IVES                         23
    expressly identifying that venue, and the refiled charges were
    supported exclusively by an ICE officer’s affidavit. We thus
    hold that the district court erred when it denied Zavala
    sentencing credit for the post-indictment period during which
    ICE detained him pending criminal prosecution.
    B. Pre-Indictment Detention
    As for the pre-indictment period, Zavala was subject to a
    reinstated order of removal on his first day in ICE custody,
    September 20, 2010, and he did not contest this order,
    meaning ICE could have deported him at any time thereafter.
    8 U.S.C. § 1231(a)(5) (stating that “the alien shall be
    removed under the prior order at any time after the reentry”).
    ICE nonetheless continued to detain Zavala until October 6,
    2010, when he was indicted for illegal reentry.
    As we stated earlier, the BOP Program Statement does not
    bar Zavala from receiving sentencing credit during any period
    in which he was being detained pending potential
    prosecution. The record before us, however, does not show
    whether he was held pending potential criminal prosecution,
    and if so, for what part of the pre-indictment period. On the
    one hand, execution of a removal order is not required to be
    instantaneous, see § 1231(a)(1), and it is therefore possible
    that Zavala’s continuing detention was related to the process
    of implementing the deportation order.16 On the other hand,
    the process of indicting a criminal defendant is ordinarily not
    a one-day affair. Usually it requires some investigation and
    deliberation before a decision to indict (or to file a criminal
    complaint) is made by the criminal authorities, normally the
    16
    We note that when Zavala was previously removed in 2006, ICE
    deported him just one day after it obtained the order of removal.
    24                         ZAVALA V. IVES
    U.S. Attorney’s Office. During that process, federal
    prosecutors and immigration officials often cooperate in
    determining whether criminal charges are warranted and
    particularly in ensuring the alien’s presence at the criminal
    proceedings. Zavala is entitled to credit for the latter type of
    detention—detention for the purpose of ensuring his presence
    at his prosecution—but not for the former type—detention for
    the purpose of executing the removal order.17 Because the
    district court erred in holding that as a matter of law Zavala
    could not receive any credit toward his sentence for time
    spent in ICE detention, it failed to consider whether that
    detention was pending deportation or pending potential
    prosecution. We therefore remand for the district court to
    determine in the first instance whether and when, during the
    pre-indictment period, Zavala’s detention status changed
    from detention pending deportation to detention pending
    potential prosecution.
    We hold that, on remand, the government has the burden
    of proving that the pre-indictment detention was for the
    17
    To be clear, we disagree with the statement in Abpikar v. Lompoc
    Federal Bureau of Prisons relied upon by the magistrate judge in this
    case. The magistrate judge held, quoting Abpikar, that the filing of “a
    charge [by a U.S. Attorney] or [a] determination of probable cause” by a
    grand jury is required before detention can constitute “official detention”
    within the meaning of § 3585(b). Abpikar, 
    2012 WL 3777156
    , at *3. First,
    in cases concerning detention by law enforcement officials, sentencing
    credit is awarded from the time of arrest, not from the time that charges
    are formally filed or an indictment returned. See BOP Program Statement
    5880.28 at 1-21. Second, as 
    explained supra
    , the approach we adopt has
    already been successfully applied to detention by immigration officials,
    and BOP already regularly calculates sentencing credit in the analogous
    state detention context. Moreover, the Abpikar approach (also propounded
    by the dissent) has no basis in the text of the statute and would fail to
    address arbitrary sentencing disparities.
    ZAVALA V. IVES                         25
    purpose of deportation rather than potential prosecution. This
    burden is justified for two reasons. First, it furthers judicial
    efficiency in light of the “judicial estimate of the probabilities
    of the situation.” 2 McCormick on Evidence § 337 (7th ed.
    2013). After all, we know how this story ends: Zavala was
    not deported, but prosecuted. This is so in all sentencing
    credit cases arising under § 3585(b). In such cases, it is
    always clear that at some point in time the government
    elected to pursue the possibility of prosecution, rather than to
    deport the alien in the normal course. Had it chosen
    otherwise, the question of credit toward a criminal sentence
    would not arise. In other words, the most likely outcome is
    that the alien is entitled to some sentencing credit beyond that
    credited from the date on which the indictment or formal
    charges were filed.
    Second, evidence as to the reason for an alien’s detention
    “is peculiarly accessible to one of the parties,” Edmund M.
    Morgan, Instructing the Jury Upon Presumptions and Burden
    of Proof, 47 Harv. L. Rev. 59, 79 (1933). The government
    unquestionably has superior access to the critical
    information—i.e. reports of investigation by ICE officers,
    records of the criminal investigation component of ICE,
    sworn statements by investigating officers, the time and
    contents of communications between ICE officers and
    prosecutorial agencies, and so forth—the information that is
    determinative of when an alien’s detention status changed
    from detention pending deportation to detention pending
    potential prosecution. The fact-finding required on remand is
    not some amorphous “inquiry into the elusive intent of
    individual [ICE] officers,” as the dissent contends. Dissent at
    12. Rather, it is primarily a matter of reviewing records that
    ICE already maintains in the ordinary course of its operations.
    26                         ZAVALA V. IVES
    For example, the government could meet its burden of
    proving that pre-indictment detention was for the purpose of
    deportation rather than potential prosecution by producing
    evidence that proceedings to determine deportability were
    actively being pursued, or, where a final removal order has
    already been obtained (as in this case), that it was in the
    process of making logistical arrangements for the detainee’s
    departure from the country, and that it was not merely
    awaiting action by the U.S. Attorney’s Office or helping build
    a criminal case.18
    We accordingly remand for the district court to conduct
    an evidentiary hearing. The relevant question on remand is
    whether the Government can establish that Zavala’s detention
    from September 20, 2010 to October 5, 2010 was not for the
    purpose of potential prosecution.
    IV.
    We hold that when immigration officials detain an alien
    pending potential prosecution, the alien is entitled under
    § 3585(b) to credit toward his criminal sentence. We also
    hold that an alien is entitled to credit for all time spent in ICE
    detention subsequent to his indictment or the filing of formal
    criminal charges against him. Finally, we hold that where a
    factual dispute exists, the district court must hold an
    evidentiary hearing as to whether an alien’s detention by ICE
    18
    To be clear: the foregoing are merely examples of how the
    government could meet its burden of proving that detention was not for
    the purpose of securing the detainee’s presence at a criminal prosecution.
    We, of course, do not imply in any way that “official detention” can occur
    only subsequent to a final removal order. Quite the contrary. To the extent
    that the dissent suggests otherwise, it simply misunderstands our opinion.
    ZAVALA V. IVES                         27
    prior to the date of his indictment or the filing of criminal
    charges against him constituted detention pending
    prosecution.
    REVERSED AND REMANDED.
    CALLAHAN, Circuit Judge, concurring in part and
    dissenting in part:
    At issue is how much of the time that an alien spends in
    the custody of the U.S. Immigration and Customs
    Enforcement Agency (ICE) prior to the commencement of a
    criminal sentence must be credited against that alien’s
    sentence for illegal reentry. I agree with the majority that,
    under 18 U.S.C. § 3585(b), an alien is eligible for credit for
    all time spent in ICE custody from the day he or she is
    indicted or criminally charged. On that day, the alien
    becomes subject to the U.S. Attorney General’s control and
    thus is in “official detention” within the meaning of § 3585(b)
    as the Supreme Court and the U.S. Bureau of Prisons (BOP)
    have interpreted that term. Reno v. Koray, 
    515 U.S. 50
    ,
    55–56 (1995); U.S. Dep’t of Justice, BOP Program
    Statement No. 5880.28(c).
    The majority, however, also adopts a broader
    interpretation of § 3585(b), that “an alien is entitled to credit
    toward his criminal sentence . . . for the period during which
    ICE detained the alien pending potential criminal
    prosecution.” Maj. Op. 22 (emphasis added). I dissent from
    this broader ruling and its application to this case because it
    (1) contravenes Supreme Court precedent, (2) violates the
    rules of statutory construction, (3) fails to defer to the BOP’s
    28                       ZAVALA V. IVES
    reasonable interpretation of § 3585(b), and (4) is
    prospectively problematic. Left in place, the rule will
    generate a slew of habeas petitions that will require district
    courts to conduct time-consuming evidentiary hearings to
    determine the elusive moment when pre-indictment
    immigration detention changed from “pending deportation”
    to “pending potential prosecution.”
    I.
    The majority’s broad rule, that time spent in ICE custody
    pending potential criminal prosecution is “official detention,”
    is inconsistent with Reno v. Koray. In that case, the Supreme
    Court held that time spent by a prisoner at a community
    treatment center after he pleaded guilty, but before he was
    sentenced, was not “official detention” within the meaning of
    § 3585(b). In so holding, the Court ruled that “credit for time
    spent in ‘official detention’ under § 3585(b) is available only
    to those defendants who were detained in a ‘penal or
    correctional facility,’ § 3621(b), and who were subject to
    BOP’s control.” 
    Koray, 515 U.S. at 58
    .1
    The majority’s interpretation of § 3585(b) cannot be
    reconciled with Koray. More than the “potential” for
    criminal prosecution is required before an alien in ICE
    1
    While the Court used the words “subject to BOP’s control,” the
    opinion as a whole makes clear that the Court also meant, more broadly,
    “subject to the discretion of the U.S. Attorney General, the Bureau of
    Prisons, or the U.S. Marshals Service.” 
    Koray, 515 U.S. at 60
    n.4
    (quoting BOP Program Statement No. 5880.28(c) (July 29, 1994)). I use
    the shorthand “subject to the Attorney General’s control,” because the
    Attorney General’s control is inclusive of that of the BOP and the U.S.
    Marshals Service (USMS), which operate under the Department of
    Justice.
    ZAVALA V. IVES                              29
    custody becomes subject to the Attorney General’s control.
    The potential for prosecution of an alien in civil immigration
    custody exists from the moment an alien is apprehended by
    ICE. Rather, for an alien in ICE custody to be in “official
    detention” within the meaning of § 3585(b), as the Supreme
    Court has interpreted that term, the alien must be indicted or
    criminally charged.2 Only then is an alien in ICE’s custody
    “subject to [the Attorney General’s] control” as a result of his
    or her immigration offense, and thus entitled to credit against
    his or her sentence. 
    Koray, 515 U.S. at 58
    . An ICE officer
    may play a part in building a criminal case, but the emergent
    intention of an ICE officer to refer a case for criminal
    prosecution has no bearing on whether an alien in ICE
    custody is subject to the Attorney General’s control and thus
    in “official detention.”
    A review of the Supreme Court’s extensive analysis of the
    term “official detention” in Koray exposes the majority’s
    error. The Court looked to § 3585(b)’s larger statutory
    scheme, including other sentencing provisions showing that
    “official detention” means “in a penal or correctional facility”
    that is “subject to BOP control.” 
    Id. at 58–59
    (internal
    quotation marks omitted). Specifically, the Supreme Court
    looked to “§ 3585(a) and related sentencing provisions,” and
    observed:
    2
    The government has not developed an argument that time spent in ICE
    custody is not “official detention” because ICE facilities are not penal or
    correctional facilities. Accordingly, I assume that ICE facilities qualify
    as penal or correctional facilities even though immigration detention is
    civil in nature. See 18 U.S.C. § 3142(a), (d) (indicating that “detention”
    within the meaning of the Bail Reform Act may include an immigration
    official’s custody of “a person charged with [a criminal] offense”).
    30                     ZAVALA V. IVES
    Section 3585(a) provides that a federal
    sentence “commences” when the defendant is
    received for transportation to or arrives at “the
    official detention facility at which the
    sentence is to be served.” Title 18 U.S.C.
    § 3621, in turn, provides that the sentenced
    defendant “shall be committed to the custody
    of the Bureau of Prisons,” § 3621(a), which
    “may designate any available penal or
    correctional facility . . . , whether maintained
    by the Federal Government or otherwise . . . ,
    that the Bureau determines to be appropriate
    and suitable,” § 3621(b) (emphasis added).
    The phrase “official detention facility” in
    § 3585(a) therefore must refer to a
    correctional facility designated by the Bureau
    for the service of federal sentences, where the
    Bureau retains the discretion to “direct the
    transfer of a prisoner from one penal or
    correctional facility to another.” § 3621(b).
    
    Id. at 58
    (alterations and emphasis in original).
    The Court explained that its “reading of § 3585(a) is
    reinforced by other provisions governing the administration
    of federal sentences,” including language in § 3622 showing
    that “official detention” means “subject to BOP control.” 
    Id. Reasoning that
    “the words ‘official detention’ should bear the
    same meaning in subsections (a) and (b) of § 3585 as they do
    in the above related sentencing statutes,” the Court found that
    § 3585(b) turned on whether the detention was subject to the
    control of the BOP (or the U.S. Attorney General or USMS).
    
    Id. It ruled
    that “credit for time spent in ‘official detention’
    under § 3585(b) is available only to those defendants who
    ZAVALA V. IVES                       31
    were detained in a ‘penal or correctional facility,’ § 3621(b),
    and who were subject to BOP’s control.” 
    Id. The Court
    explained that “[t]he context and history of § 3585(b) also
    support this view,” as does the BOP’s Program Statement No.
    5880.28(c), which is due deference. 
    Id. at 59–61.
    Recognizing that its rule is inconsistent with the rule
    announced in Koray, the majority attempts to relegate the
    Supreme Court’s rule to the status of dicta. The majority
    relies on a footnote in Koray where the Court declined to
    address the propriety of the BOP’s policy of granting “credit
    under § 3585(b) to a defendant who is denied bail pursuant to
    state law and held in the custody of state authorities.” 
    Id. at 63
    n.5. But what the Supreme Court did rule was not undone
    by a footnote stating what applications of that rule the Court
    declined to address. Thus, the broad rule announced by the
    majority in this case, which does not require an alien’s
    custody by ICE to be subject to the Attorney General’s
    control to qualify as “official detention” under § 3585(b),
    contravenes Reno v. Koray.
    II.
    The majority’s broad rule also runs contrary to the rules
    of statutory construction. As explained above, Koray’s
    interpretation of § 3585(b) followed the “normal rule of
    statutory construction that identical words used in different
    parts of the same act are [presumed] to have the same
    meaning.” Sullivan v. Stroop, 
    496 U.S. 478
    , 484 (1990)
    (internal quotation marks omitted).          The majority’s
    interpretation of § 3585(b) violates this rule by interpreting
    “official detention” in § 3585(b) not to mean “subject to [the
    Attorney General’s] control,” even though that is part of the
    32                        ZAVALA V. IVES
    term’s meaning as it is used in subsection § 3585(a). 
    Koray, 515 U.S. at 58
    .
    In doing so, the majority violates an even more
    fundamental rule of statutory construction, the rule that
    prohibits “[a]scribing various meanings to a single iteration”
    of a statutory term in different applications. Ratzlaf v. United
    States, 
    510 U.S. 135
    , 143 (1994) (internal quotation marks
    omitted); see also Clark v. Martinez, 
    543 U.S. 371
    , 386
    (2005) (rejecting “the dangerous principle that judges can
    give the same statutory text different meanings in different
    cases”). The majority holds that “official detention” in
    § 3585(b) means one thing (what the majority says it does) in
    the context of custody by ICE but another thing (what the
    Supreme Court said it does in Koray) in the context of
    custody by a community treatment center. Such an approach
    to understanding a statute is in tension with the rule of law
    and should be rejected. 
    Clark, 543 U.S. at 382
    (to accept that
    the same statutory provision could have multiple meanings
    “would render every statute a chameleon, its meaning subject
    to change . . . in each individual case”).
    It is true that, in Koray, the Supreme Court also construed
    § 3585(b) in conjunction with the Bail Reform Act of 1984,
    which is not directly at issue here.3 
    Koray, 515 U.S. at 56
    –57. Doing so made sense “because the Bail Reform Act
    of 1984 was enacted in the same statute as the Sentencing
    Reform Act of 1984, of which § 3585 is a part.” 
    Id. 3 It
    does not follow that the Supreme Court’s extensive analysis of the
    Sentencing Reform Act, which is at issue here, and resultant ruling
    regarding § 3585(b)’s meaning, which is controlling here, may be ignored
    or distinguished as only applicable to custody in a community treatment
    center. See 
    Koray, 515 U.S. at 55
    –65.
    ZAVALA V. IVES                              33
    Accordingly, Congress could be presumed to have “legislated
    with reference to” the terms of § 3585 in drafting the Bail
    Reform Act. 
    Id. at 57
    (quoting Gozlon–Peretz v. United
    States, 
    498 U.S. 395
    , 408 (1991)). The same cannot be said
    of the Immigration and Nationality Act (INA). To the extent
    that immigration law is relevant to construing § 3585, it only
    confirms that immigration detention is civil rather than
    criminal in nature. See Cabral-Avila v. INS, 
    589 F.2d 957
    ,
    959 (9th Cir. 1978).
    The majority contradicts itself in attempting to align the
    terms “detention” and “release” in the INA with the same
    terms in the Bail Reform Act. Maj. Op. 13 (citing 8 U.S.C.
    §§ 1226(a)(1)–(2), 1231(a)(2)). First, as the majority later
    states, these terms of the Bail Reform Act “obviously” do not
    apply to civil immigration custody. 
    Id. at 14
    n.8. Second, if
    Congress intended immigration “detention” within the
    meaning of the INA to be “official detention” within the
    meaning of the Sentencing Reform Act, then all time spent in
    ICE custody would be entitled credit. The majority rejects
    this proposition.4
    4
    Indeed, the Bail Reform Act supports the view that an alien in ICE
    custody is not in “official detention” before criminal charges are filed.
    The Act requires that “a person charged with [a criminal] offense” and
    awaiting trial, disposition of appeals, or commencement of his sentence
    be either “released” or “detained.” 18 U.S.C. § 3142 (a); see also 
    id. § 3143.
    Thus, a person, including an alien in immigration custody, 
    id. § 3142(d),
    becomes subject to official detention once “charged with [a
    criminal] offense.” 
    Id. §§ 1342,
    1343. The INA, by contrast, only
    addresses the “detention” or “release” of a person who has been “arrested
    and detained pending a decision on whether the alien is to be removed
    from the United States.” 8 U.S.C. § 1226(a). Such civil immigration
    “detention” is not, as the majority agrees, “official detention” within the
    meaning of § 3585(b).
    34                     ZAVALA V. IVES
    By giving the term “official detention” a different
    meaning in a different category of cases to which it applies,
    the majority “invent[s] a statute rather than interpret[s] one.”
    
    Clark, 543 U.S. at 378
    . The majority’s invention might be
    sensible, but the job of judges is to interpret statutes, not to
    rewrite them.
    III.
    The majority also oversteps the judicial role by failing to
    provide any deference to the interpretation of “official
    detention” set forth in the BOP’s Program Statement.
    According to the BOP:
    Official detention does not include time spent
    in the custody of the U.S. Immigration and
    Naturalization Service (INS) under the
    provisions of 8 U.S.C. § 1252 pending a final
    determination of deportability. An inmate
    being held by INS pending a civil deportation
    determination is not being held in “official
    detention” pending criminal charges.
    BOP Program Statement 5880.28, at 1-15A.
    The government appears to contend that this part of the
    program statement means that an alien is never in “official
    detention” while in ICE custody. I join the majority in
    declining to defer to this unreasonable interpretation of the
    program statement’s interpretation of a statutory term.
    But the program statement itself is “entitled to some
    deference.” 
    Koray, 515 U.S. at 61
    . By its text, the program
    statement does not deny sentencing credit for all time an alien
    ZAVALA V. IVES                             35
    is held by ICE. Rather, a reasonable inference from the
    program statement is that an alien in ICE custody is in
    “official detention” once “criminal charges” are “pending.”
    BOP Program Statement 5880.28, at 1-15A. As used,
    “pending” logically means filed but not yet resolved. See
    Black’s Law Dictionary (10th ed. 2014) (used as a
    preposition, as it is here, “pending” primarily means “1.
    Throughout the continuance of; during ”; used as an adjective, it primarily means “1.
    Remaining undecided; awaiting decision ”).
    While the program statement is ambiguous when read in
    isolation, a reading of the statement as allowing credit for
    time spent in civil immigration custody once criminal charges
    are filed is confirmed by other parts of the same statement,
    which emphasize that “‘official detention’ [means] subject to
    the discretion of the Attorney General and the U.S. Marshals
    Service with respect to the place of detention.” BOP Program
    Statement 5880.28, at 1-14F. An alien in ICE custody is
    subject to the Attorney General’s control when criminal
    charges have been filed and remain pending.5 At this point,
    the Attorney General has “discretion to ‘direct the transfer of
    a prisoner from one penal or correctional facility to another.’”
    
    Koray, 515 U.S. at 58
    (quoting § 3621(b)).
    The majority errs by failing to defer to this interpretation
    of “official detention” set forth in the Program Statement, as
    5
    The program statement does not say “pending criminal charging” or
    “awaiting the filing of charges” as the majority would prefer to read it.
    See Maj. Op. 17 n.11. As explained above, other parts of the program
    statement make this clear. The BOP’s inclusion of the word
    “determination” in the phrase “pending a civil deportation determination”
    but omission of such a verbal noun from the subsequent phrase “pending
    criminal charges,” also undermines the majority’s view that the latter
    phrase anticipates some action, as in “awaiting the filing of charges.”
    36                     ZAVALA V. IVES
    it is a reasonable interpretation of an ambiguous statutory
    term that was provided by the agency Congress charged with
    administering that term. Indeed, it is an interpretation that the
    Supreme Court has accorded deference. 
    Koray, 515 U.S. at 61
    ; see also Tablada v. Thomas, 
    533 F.3d 800
    , 806–07 (9th
    Cir. 2008).
    IV.
    The majority’s interpretation of “official detention” has
    the additional flaw of being difficult for district courts to
    administer. The majority remands “for the district court to
    determine in the first instance whether and when, during the
    pre-indictment period, Zavala’s detention status changed
    from detention pending deportation to detention pending
    potential prosecution.” Maj. Op. 24. The majority directs
    “the district court to conduct an evidentiary hearing,” but
    provides little guidance for determining when detention by
    ICE shifts from “pending deportation to . . . pending potential
    prosecution.” 
    Id. at 25,
    26. Presumably the government
    would be required to put on evidence showing when an ICE
    official of sufficient rank or involvement in a petitioner’s
    detention developed a sufficiently concrete intention to
    recommend criminal prosecution.
    As the district court observed, this “interpretation of
    section 3585(b) would be extremely difficult . . . to
    administer.” Zavala v. Ives, No. CV 13-3603-JFW E, 
    2013 WL 4763839
    , at *4 (C.D. Cal. Sept. 3, 2013). The majority
    dismisses this concern on the basis of four unpublished
    district court decisions granting credit for time spent in
    ZAVALA V. IVES                                37
    immigration detention.6 These four decisions, which until
    today were contrary to the overwhelming weight of
    authority,7 are hardly representative of the stream of habeas
    petitions we can expect under the majority’s rule. These
    decisions do not demonstrate that administering the rule will
    not burden district courts and the government by requiring
    fact-intensive inquiries into the purpose of an alien’s
    detention. The fact that the BOP sometimes grants
    sentencing credit for time spent in state or foreign criminal
    custody does not negate the district court’s practical concern

    38                         ZAVALA V. IVES
    either. The BOP practice does not require an inquiry into the
    elusive intent of individual officers, and it does not allow
    civil detention to be deemed criminal in nature based on the
    intent of an official who lacks authority to criminally
    prosecute.
    The disproportionate cost to benefit of the majority’s rule
    is apparent in this case. Here, the difference between my
    perspective and the majority’s concerns some fraction of the
    sixteen days that Zavala was held by ICE before the
    indictment was filed. Under the majority’s approach, the
    district court will have to hold an evidentiary hearing probing
    the thought processes of ICE officials to determine when
    during these sixteen days Zavala’s custody became due to
    “potential criminal prosecution.”8 I do not mean to discount
    the value of Zavala’s time, but only to highlight the practical
    problems inherent to administering the majority’s
    interpretation.9
    8
    In applying its rule, the majority appears to limit its reach such that
    “official detention” may not occur until, at the earliest, “a final removal
    order” has issued. Maj. Op. 26. This hedge may have the effect of
    reducing the prospective burden on the district courts and the government
    of administering the rule. But see 
    id. 26 n.18
    (retreating from this hedge).
    Regardless, a fact-intensive inquiry into when, after a final deportability
    determination, ICE developed a sufficiently concrete intention to
    recommend criminal prosecution would still be required, at least when the
    government does not capitulate. I note that the majority’s limitation of its
    rule further unravels whatever logic underlies its rule. The limitation
    looks to whether deportation proceedings are actively ongoing rather than
    to whether the government has decided potentially to pursue criminal
    prosecution.

    I acknowledge that, in some cases, aliens may spend inequitably
    lengthy periods of time in ICE custody before unlawful reentry charges
    are initiated. This case does not present an occasion to determine if a
    ZAVALA V. IVES                              39
    The bright-line rule adopted by most courts, that ICE
    custody becomes “official detention” within the meaning of
    § 3585(b) when an alien is indicted or criminally charged,
    makes much more sense as a matter of efficient
    administration.      Given competing, equally reasonable
    interpretations, it is safe to say that Congress intended the
    interpretation that would be less problematic prospectively.
    
    Koray, 515 U.S. at 64
    (rejecting an interpretation of
    § 3585(b) that “would require a fact-intensive inquiry into the
    circumstances of confinement”). Moreover, a bright-line rule
    furthers Congress’s stated interest in providing prisoners and
    the public with prompt, precise information about how much
    time a prisoner must spend in prison. S. Rep. No. 98–225, at
    46 (1983) (recognizing the value of a “system of sentencing
    whereby the offender, the victim, and society all know the
    prison release date at the time of the initial sentencing by the
    court, subject to minor adjustments based on prison behavior
    called ‘good time’”); see also 
    Koray, 515 U.S. at 64
    (preferring an interpretation of § 3585(b) that “provides both
    [the government] and the defendant with clear notice”).10
    defendant would be entitled to credit for “civil detentions which are mere
    ruses to detain a defendant for later criminal prosecution.” United States
    v. Cepeda-Luna, 
    989 F.2d 353
    , 357 (9th Cir. 1993) (recognizing a possible
    exception to the general rule that the Speedy Trial Act does not apply to
    immigration detention).
    10
    My consideration of prospective effects is not my principal reason for
    construing § 3585(b) to require custody to be subject to the Attorney
    General’s control in order to qualify as “official detention.” It is clear,
    though, that the majority’s principal argument is one of policy, that
    similarly situated defendants should not be treated disparately. While this
    is a compelling policy concern, it is one that the Supreme Court has
    expressly dismissed in interpreting § 3585(b). 
    Koray, 515 U.S. at 64
    .
    Indeed, the same kind of disparity in treatment for similarly situated
    defendants would arise under the majority’s rule. Some defendants held
    40                         ZAVALA V. IVES
    V.
    Despite my dissent from the majority’s broad rule, I agree
    with the majority’s narrower rule: “Where ICE retains an
    alien in custody subsequent to an indictment or the filing of
    criminal charges and the alien is then convicted of those
    charges, . . . the alien is entitled to sentencing credit” for the
    intervening period of detention. Maj. Op. 22. Applying this
    rule to this case, I would affirm the district court’s denial of
    sentencing credit for Zavala’s first stint in ICE custody—the
    sixteen days from his detainment by ICE until his indictment
    in the U.S. District Court for the District of Nevada for illegal
    reentry.11
    When Zavala was indicted, however, he became subject
    to the Attorney General’s control and, in fact, was promptly
    transferred to USMS custody. I would vacate and remand the
    in ICE custody will receive sentencing credit because their custody is
    “pending potential criminal prosecution,” while others—even some in the
    same facility, in the same cell—will not because they have not yet crossed
    that inscrutable line.
    11
    I disagree with the majority’s argument that, under Koray, all ICE
    custody is “official detention” under § 3585(b) because the now-abolished
    Immigration and Naturalization Service used to fall under the Attorney
    General’s purview. Through the Homeland Security Act of 2002, Pub. L.
    No. 107-296, 116 Stat. 2135 (Nov. 25, 2002), Congress removed
    immigration custody from the Attorney General’s control. Congress
    legislated against the clear backdrop of the interpretation of § 3585(b) set
    forth in Koray, the government’s construction § 3585(b) in the BOP
    Program Statement, and the government’s longstanding practice of
    denying sentencing credit for time spent in immigration custody. We must
    presume that Congress was aware of these “settled judicial and
    administrative interpretation[s]” when it enacted the Homeland Security
    Act. Comm’r of Internal Revenue v. Keystone Consol. Indus., Inc.,
    
    506 U.S. 152
    , 159 (1993).
    ZAVALA V. IVES                        41
    district court’s denial of sentencing credit for Zavala’s second
    stint in ICE custody—the twelve days from his transfer back
    into ICE custody following dismissal of the criminal case
    against him due to improper venue until he was again charged
    for illegal reentry in the U.S. District Court for the Central
    District of California. This time period occurred after Zavala
    was indicted and initially became subject to the Attorney
    General’s control. While no criminal case was actually
    pending against Zavala during this period, Zavala has made
    a prima facie showing that he remained subject to the
    Attorney General’s control. See Boniface v. Carlson,
    
    856 F.2d 1434
    , 1436 (9th Cir. 1988) (per curiam) (prisoner
    bears the burden to establish his entitlement to credit against
    his federal sentence for time served on his state sentence). As
    the majority notes, the language of the government’s
    proposed order of dismissal indicated its intention to refile
    criminal charges in the proper venue and expressly identified
    that venue. The dismissal may be fairly characterized as the
    equivalent of a transfer of a filed criminal case from one
    district to another for purposes of applying § 3585(b).
    Accordingly, on the record presented, it appears that Zavala
    remained subject to the Attorney General’s control and thus
    in “official detention” within the meaning of § 3585(b) during
    this time. On remand, unless the government rebuts this
    showing, Zavala would be due twelve days of credit toward
    his sentence for illegal reentry.
    VI.
    “Official detention” in § 3585(b) does not take on
    different meanings in different contexts, as the majority
    would have it. Instead, in all contexts, a defendant is in
    “official detention” within the meaning of § 3585(b) when he
    or she is (1) detained in a correctional facility or similar
    42                    ZAVALA V. IVES
    setting and (2) subject to the Attorney General’s control.
    This interpretation of § 3585(b) is compelled by Koray,
    correct as a matter of statutory construction and
    administrative deference, and prudent in terms of prospective
    effects. Applying this rule, I would affirm in part, vacate in
    part, and remand to the district court.
