    ST. EVE, Circuit Judge. Indiana’s Sex Offender Registration
    Act (“SORA”) imposes registration requirements and re-
    strictions on sex offenders who reside, work, or study in the
    State. 
    Ind. Code § 11-8-8-1
     et seq. By virtue of the State su-
    preme court’s construction of the Indiana Constitution, Indi-
    ana’s Ex Post Facto Clause prohibits retroactive application of
    SORA to offenders convicted before its enactment unless the
    marginal effects of doing so would not be punitive. Wallace v.
    State, 
    905 N.E.2d 371
     (Ind. 2009); Jensen v. State, 
    905 N.E.2d 384
    (Ind. 2009). If an offender was under no registration require-
    ment prior to SORA’s passage, imposing a registration re-
    quirement in the first instance is impermissibly punitive. Wal-
    lace, 905 N.E.2d at 371. The Indiana Supreme Court has held,
    however, that if another state previously subjected a pre-
    SORA offender to a registration requirement, requiring him
    to register in Indiana is not punitive. See, e.g., Tyson v. State, 
    51 N.E.3d 88
     (Ind. 2016). Indiana caselaw thus has the peculiar
    effect of permitting the State to treat similarly situated offend-
    ers differently based solely on whether an offender had an
    out-of-state registration obligation. That feature underlies the
    present appeal.
    The plaintiffs, six sex offenders residing in Indiana, were
    convicted prior to SORA’s passage. Each of them had to reg-
    ister in another state. After moving to Indiana, the State re-
    quired them to register under SORA. Absent their out-of-state
    registration obligations, Indiana’s Constitution would pro-
    hibit SORA’s application to them. Plaintiffs challenge the con-
    stitutionality of SORA on three fronts, arguing that it violates
    their right to travel under the Privileges or Immunities
    Clause, their right to equal protection under the Fourteenth
    Amendment, and Article I’s prohibition on ex post facto laws.
    The district court granted summary judgment for the
    No. 19-2523                                                 3
    plaintiffs on all claims, and Indiana appealed. A divided
    panel of this Court affirmed the district court, but we subse-
    quently agreed to hear the case en banc.
    We now reverse. SORA does not violate the right to travel
    because it does not expressly discriminate based on residency,
    as consistently required by the Supreme Court. Plaintiffs’ ex
    post facto claim is likewise precluded by precedent. Applying
    Smith v. Doe, 
    538 U.S. 84
     (2003), we hold that SORA is not “so
    punitive either in purpose or effect” as to surmount Indiana’s
    nonpunitive intent for the law. But because the district court
    did not address whether SORA passes rational basis scrutiny
    under an equal protection analysis, we remand for considera-
    tion of the equal protection claim.
    I.
    A.
    The Indiana General Assembly enacted SORA, also
    known as “Zachary’s Law,” in 1994. SORA establishes both
    requirements and restrictions for qualifying sex offenders,
    and it authorizes the Indiana Department of Correction
    (“IDOC”) to collect and publish data about them. 
    Ind. Code § 11-8-2-13
    (b). Under SORA, offenders must register by re-
    porting to local law enforcement at least once annually in
    every county where they reside, work, or study. §§ 11-8-8-14,
    11-8-8-7. Reporting requirements are more frequent for “sex-
    ually violent predators”—every 90 days—and offenders with-
    out permanent housing—every 7 days. §§ 11-8-8-14, 11-8-8-
    12. Registration entails providing detailed personal infor-
    mation, including: a photograph; legal name, date of birth,
    and physiological features; identification numbers; internet
    usernames and email addresses; residential, school, and
    4                                                  No. 19-2523
    workplace addresses; vehicle information and license plate
    number; and any “other information required by the
    [IDOC].” § 11-8-8-8(a). Offenders must report any change to
    this information within 72 hours. SORA also mandates that
    law enforcement officers contact offenders once a year to ver-
    ify their residences (every 90 days for sexually violent offend-
    ers). § 11-8-8-13(a). And offenders pay a yearly $50 registra-
    tion fee, plus a $5 fee any time they must register a change of
    address. § 36-2-13-5.6.
    Certain offenders are subject to more stringent require-
    ments. A “sexually violent predator” must notify law enforce-
    ment if he plans to be absent from his residence for more than
    72 hours and must register in the county that he visits. § 11-8-
    8-18. An “offender against children” may not work or volun-
    teer at a school, daycare, youth program center, or public park
    and cannot live within 1,000 feet of these locations. §§ 35-42-
    4-10(c), 35-42-4-11. A “serious sex offender” may not enter
    school property. § 35-42-4-14. An offender’s failure to comply
    with SORA can result in criminal sanctions.
    Following its enactment, SORA underwent several expan-
    sions. Indiana broadened the list of crimes that trigger regis-
    tration requirements, and it amended SORA to require regis-
    tration for individuals convicted of substantially similar of-
    fenses in another state. On July 1, 2006, the General Assembly
    extended SORA’s requirements to any “person who is re-
    quired to register as a sex offender in any jurisdiction.” § 11-
    8-8-5(b)(1). In its current form, SORA requires offenders to
    register if they were:
    (1) convicted of an enumerated Indiana criminal offense,
    §§ 11-8-8-4.5, 11-8-8-5(a);
    No. 19-2523                                                    5
    (2) convicted of a “substantially similar” offense in an-
    other jurisdiction, § 1-1-2-4(b)(3); or
    (3) required to register by another state (the “other-juris-
    diction provision”), § 11-8-8-5(b)(1).
    By its plain terms, SORA covers any offender who fits within
    these categories—regardless of his date of conviction.
    B.
    While SORA is fully retrospective as a statutory matter,
    the Indiana Constitution constrains its applicability to offend-
    ers with pre-SORA offenses. The Indiana Supreme Court ar-
    ticulated these constitutional boundaries in a series of deci-
    sions, beginning with Wallace v. State. In Wallace, the court ap-
    plied its own version of the Supreme Court’s “intent-effects”
    test and held that SORA had a punitive effect as applied to
    Wallace—who had been charged, convicted, and served his
    sentence before Indiana enacted SORA—and that it thus vio-
    lated Indiana’s Ex Post Facto Clause. 905 N.E.2d at 379, 384.
    Wallace did not foreclose all retroactive applications of
    SORA, however. Indeed, the same day that it decided Wallace,
    the Indiana Supreme Court issued its opinion in Jensen v.
    State. Unlike Wallace, Jensen pleaded guilty in 2000—after
    SORA’s enactment. 905 N.E.2d at 388. At the time of his con-
    viction, SORA required that he register as a sex offender for
    ten years. Id. at 389. Before the expiration of Jensen’s ten-year
    registration requirement, the Indiana General Assembly
    amended SORA in 2006 to mandate that offenders like him
    register for life. He argued that this extension as applied to
    him violated Indiana’s Ex Post Facto Clause, but the Indiana
    Supreme Court disagreed. In contrast to Wallace, who had no
    obligations before the legislature amended SORA to cover
    6                                                    No. 19-2523
    him, the “‘broad and sweeping’ disclosure requirements were
    in place and applied to Jensen at the time of his guilty plea in
    January 2000. Nothing in that regard was changed by the 2006
    amendments.” Id. at 394. Increasing only the length of an ex-
    isting registration obligation did not rise to the level of “pun-
    ishment” such that it violated the Indiana Constitution. Id. at
    391–93.
    After Jensen, the Indiana Supreme Court continued to fo-
    cus on the marginal effects of SORA and its amendments. In
    State v. Pollard, 
    908 N.E.2d 1145
     (Ind. 2009), it said that retro-
    actively applying a new residency restriction was “adding
    punishment.” 
    Id. at 1154
    . The court’s decision in Lemmon v.
    Harris, 
    949 N.E.2d 803
     (Ind. 2011), though, concluded that an
    amendment that reclassified someone from a sex offender to
    a “sexually violent predator” was not punitive because, just
    like for Jensen, it amounted only to an extension of pre-exist-
    ing obligations and was not “any more punitive.” 
    Id.
     at 810–
    11, 813 n.19.
    Up to this point, each case had asked whether SORA had
    a marginal punitive effect compared to those requirements al-
    ready imposed by Indiana law. A trio of 2016 cases fleshed out
    the retroactive applicability of SORA to offenders whose ini-
    tial registration requirements originated in other states. In Ty-
    son v. State, the court upheld the registration requirement for
    an offender obligated to register under Texas law at the time
    of his conviction. 51 N.E.3d at 90. It did so even though his
    conviction and Texas registration obligation occurred before
    Indiana’s SORA covered his offense. Id. In reaching this result,
    the court concluded that the effect of “maintaining a registry
    requirement across state lines does not amount to a punitive
    burden” in violation of the state constitution. Id.
    No. 19-2523                                                      7
    The court extended this reasoning in State v. Zerbe, 
    50 N.E.3d 368
     (Ind. 2016). Zerbe was convicted in Michigan in
    1992, before either Michigan or Indiana had enacted sex of-
    fender registration laws. 
    Id. at 369
    . Michigan nevertheless re-
    quired Zerbe to register upon his release from prison because
    Michigan did not share Indiana’s stricter Ex Post Facto Clause
    and applied its law retroactively. 
    Id. at 371
    . This twist changed
    nothing: the effect of maintaining that registration in Indiana
    was not punitive. 
    Id.
     at 370–71. As the court clarified, “it is not
    Zerbe’s crime that triggers his obligation to register as a sex
    offender in Indiana; rather, it is his Michigan registry require-
    ment that does so.” 
    Id. at 370
    . The trilogy concluded with Am-
    mons v. State, 
    50 N.E.3d 143
     (Ind. 2016) (per curiam). Ammons
    had been convicted in Indiana before the passage of SORA,
    but he moved to Iowa, which obligated him to register for his
    Indiana crime. 
    Id.
     When he moved back to Indiana in 2013,
    the Indiana Supreme Court confirmed that, just like for Tyson
    and Zerbe, maintaining Ammon’s Iowa registration require-
    ment for his Indiana crime did not amount to “additional
    punishment.” 
    Id. at 145
    .
    To summarize, the question under Indiana’s Ex Post Facto
    Clause is whether SORA’s marginal effect is punitive. Main-
    taining, extending, or modifying a duty under SORA gener-
    ally is not punitive, but imposing a new duty is. It is immate-
    rial to the analysis whether Indiana law is maintaining, ex-
    tending, or modifying its own duties or those of another state.
    Likewise, it is irrelevant where or when the conviction oc-
    curred, as long as another state imposed a lawful registration
    obligation on the offender and SORA does not so significantly
    alter that obligation to result in added punishment.
    8                                                             No. 19-2523
    C.
    Plaintiffs Brian Hope, Gary Snider, Joseph Standish, Adam
    Bash, Patrick Rice, and Scott Rush are sex offenders whose
    convictions predate the enactment of SORA. With the excep-
    tion of Hope, each plaintiff’s conviction occurred in another
    state, and all the plaintiffs had to register pursuant to the sex
    offender registration laws of another state. Upon moving or
    returning to Indiana, the State required the plaintiffs to regis-
    ter as sex offenders. The circumstances leading to the plain-
    tiffs’ registration obligations under SORA fall into the same
    factual patterns addressed by the Indiana Supreme Court in
    Zerbe and Ammons.
    Hope was charged with child molestation in Indiana in
    1993, prior to SORA’s passage, and pleaded guilty. He then
    moved to Texas, which required him to register under its law.
    As in Ammons, Indiana applied SORA’s requirements to him
    upon his return to the State in 2013. Snider, Standish, Bash,
    Rice, and Rush mirror Zerbe.2 Each had to register in another
    state under its retroactive sex offender registration law and
    2  Bash’s and Snider’s cases differ from the earlier Indiana cases in one
    significant respect: both moved to Indiana before the 2006 enactment of
    the other-jurisdiction provision. In all three of the Indiana cases upholding
    the retroactive application of SORA to offenders with out-of-state regis-
    tration requirements, the plaintiffs had moved to Indiana after July 1, 2006.
    There thus was no question whether Indiana’s Constitution permits retro-
    active application of the other-jurisdiction provision. This wrinkle does
    not affect the remaining plaintiffs, who moved to Indiana after 2006. And
    we ultimately find it nondeterminative in Bash’s and Snider’s cases. On its
    face, the provision applies retroactively, and nothing in Indiana Supreme
    Court caselaw suggests that the state constitution would forbid this.
    No. 19-2523                                                               9
    later moved to Indiana, where Indiana required them to reg-
    ister under SORA.3
    The plaintiffs filed this suit alleging that as applied to
    them, SORA violates their right to travel and equal protection
    and that it runs afoul of the federal prohibition on ex post
    facto laws.4 The plaintiffs articulated the burdens that SORA
    places on them in detail. Each of them is subject to SORA’s
    more onerous reporting requirements and living and working
    restrictions given the nature of their offenses.5 SORA classifies
    all the plaintiffs as “offender[s] against children” and as “se-
    rious sex offender[s]”; four of them also qualify as “sexually
    violent predator[s].” For Snider, Standish, Rush, and Bash
    (who has full custody of his minor son), this means that they
    cannot attend school functions or parent-teacher conferences
    for their children or grandchildren or drive them to school.
    Hope, who lacks a residence, has been required to leave a
    3 There has been some disagreement throughout this litigation regard-
    ing whether Indiana required the plaintiffs to register pursuant to the
    other-jurisdiction provision or because they committed registrable of-
    fenses under SORA (or substantially similar offenses under the law of an-
    other state). Regardless, the State’s view of SORA when enforcing it is not
    pertinent to our understanding of the law and the state constitutional lim-
    its on it. We determine that SORA obligated each of the plaintiffs to regis-
    ter under the other-jurisdiction provision alone.
    4The plaintiffs originally filed two lawsuits, which the district court
    consolidated.
    5 Hope pleaded guilty to child molestation, and Standish pleaded no
    contest to attempted sexual contact with a child under 13. Rush was con-
    victed of sexual battery of a child under 12 years old. Snider was convicted
    of criminal sexual conduct in the first degree (rape), and Rice was con-
    victed of aggravated rape. Bash pleaded guilty but mentally ill to rape and
    sodomy.

    homeless shelter because it was located within 800 feet of a
    park. Snider had to move from the home he shared with his
    wife in 2006 because it fell within 1,000 feet of a daycare. Rush
    must take a day off work every time he reports. Bash, who
    relies on government financial assistance, has at times been
    unable to afford SORA’s annual registration fee and been
    placed on a payment plan.
    The district court granted summary judgment to the plain-
    tiffs on all claims and enjoined Indiana from requiring them
    to register.6 On appeal, a divided panel of this Court affirmed
    the district court’s summary judgment determination based
    on the right to travel claim. Hope v. Comm’r of Ind. Dep’t of
    Corr., 
    984 F.3d 532
     (7th Cir. 2021). It did not reach the equal
    protection or ex post facto claims. We then granted Indiana’s
    petition for rehearing en banc and vacated the panel opinion.
    We review the district court’s summary judgment deter-
    mination de novo, drawing all reasonable inferences in favor
    of the nonmovant. Peerless Network, Inc. v. MCI Commc’n Serv.,

    , 545 (7th Cir. 2019). Upon review, we reverse
    and remand.
    II.
    A.
    The plaintiffs argue that SORA violates their right to travel
    by treating them differently based on their length of residency
    in Indiana. We disagree. SORA may affect newer residents
    disproportionately, but it does not discriminate based on
    6The plaintiffs sued multiple parties, including IDOC and several
    county prosecutors and sheriffs in their official capacities. We reference
    the defendants collectively as “Indiana” or “the State.”
    No. 19-2523                                                            11
    residency. Consequently, it does not violate the right to travel
    as the Supreme Court has articulated it.
    The Supreme Court has identified three components of the
    right to travel: (1) “the right of a citizen of one State to enter
    and to leave another State,” (2) “the right to be treated as a
    welcome visitor rather than an unfriendly alien when tempo-
    rarily present in the second State,” and (3) “for those travelers
    who elect to become permanent residents, the right to be
    treated like other citizens of that State.” Saenz v. Roe, 
    526 U.S. 489
    , 500 (1999). Only the third right is at issue here.
    That right has evolved over time. Although it is constitu-
    tionally safeguarded, there is no mention of a right to travel
    in the text of the Constitution. As early as 1872, however, the
    Supreme Court recognized this right as protected by the Con-
    stitution and has articulated its contours through subsequent
    cases. 
    Id. at 503
     (tracing the right’s constitutional pedigree).
    Throughout that caselaw development, the source of the right
    to travel has shifted. In many of its earlier decisions, the Su-
    preme Court discussed the right in equal protection parlance.
    See, e.g., Zobel v. Williams, 
    457 U.S. 55
    , 60 n.6 (1982) (“Right to
    travel cases have examined, in equal protection terms, state
    distinctions between newcomers and longer term resi-
    dents.”). But in its most recent right to travel case, Saenz v. Roe,
    the Court underscored that the right is grounded in the Priv-
    ileges or Immunities Clause of the Fourteenth Amendment.7
    U.S. Const. amend. XIV, § 1; Saenz, 
    526 U.S. at
    502–03.
    7The Court has traced the three components of the right to travel to
    different parts of the Constitution. It is the third component—the right of
    new residents and longer-term residents to be treated alike—that is
    12                                                            No. 19-2523
    In Saenz, the plaintiffs challenged the constitutionality of a
    California statute that limited new residents of one year or
    less to only the welfare benefits to which they would have
    been entitled in their prior state of residence. 
    526 U.S. at 492
    .
    The Supreme Court held that this rule violated the third as-
    pect of the right to travel. The Court was not concerned with
    whether California was trying to penalize or deter travel or
    even if it was succeeding. 
    Id. at 504
    . Instead, the Court found
    that “the right to travel embraces the citizen’s right to be
    treated equally in her new State of residence” and that “the
    discriminatory classification is itself a penalty.” 
    Id. at 505
    . In
    addressing this discrimination, the Court applied strict scru-
    tiny, which California’s law failed.8 
    Id.
     at 504–05. The duration
    of a citizen’s residency and the location of his or her prior res-
    idence had no relevance to the citizen’s welfare needs, and the
    bare desire to reduce the state’s budget was not compelling
    enough to justify a complex layered hierarchy among bona
    fide California residents. 
    Id. at 507
    .
    Saenz solidified that laws infringing the right to travel
    must pass strict scrutiny. See 
    id. at 504
    . The full scope of the
    right, however, remains uncertain. There have been no Su-
    preme Court decisions interpreting the third component of
    the right to travel since Saenz. Cases before it held other dura-
    tional-residency requirements unlawful but did so under the
    covered by the Fourteenth Amendment Privileges or Immunities Clause.
    Saenz, 
    526 U.S. at
    502–03. The second component is protected by Article
    IV. 
    Id. at 501
    . The Court has found support for the first component in var-
    ious clauses but has not spoken definitively on it. 
    Id.
    8Like the question of the right to travel’s constitutional footing, opin-
    ions discussing the appropriate scrutiny for the right have arrived at dif-
    ferent answers. After Saenz, however, we apply strict scrutiny.

    394 U.S. 618
    , 622 (1969) (invalidat-
    ing statutes that deny welfare assistance to individuals during
    their first year of residency). But see Sosna v. Iowa, 
    419 U.S. 393
    ,
    396, 409 (1975) (upholding an Iowa law requiring a resident
    to live in state for one year to obtain a divorce decree).
    We agree with the plaintiffs, however, that the right to
    travel should be understood to go beyond prohibiting only
    durational-residency requirements that place a waiting pe-
    riod on benefits. It seems unlikely that a permanent distinc-
    tion between bona fide residents based on their time residing
    in a state would be any more lawful than a temporary one.
    The Supreme Court’s cases illustrate this point, although a
    majority of the Court has yet to endorse it. In Zobel, Alaska
    implemented a natural resource dividend statute that created
    “fixed, permanent distinctions between an ever-increasing
    number of perpetual classes of concededly bona fide resi-
    dents, based on how long they have been in the State.” 
    457 U.S. at 59
    . The Supreme Court held that this scheme was im-
    proper even under rational basis review. 
    Id. at 64
    . The Court
    did the same thing with a New Mexico tax exemption for Vi-
    etnam veterans who were state residents before a specific
    date. Hooper v. Bernalillo Cnty. Assessor, 
    472 U.S. 612
     (1985).
    Although the Supreme Court did not directly hold that the
    laws at issue in Zobel and Hooper implicated the right to travel,
    a plurality of the Court later concluded that the right drove
    14                                                  No. 19-2523
    those decisions. See Attʹy Gen. of N.Y. v. Soto-Lopez, 
    476 U.S. 898
    , 907–08 (1986) (plurality opinion). In the plurality’s view,
    “a permanent deprivation of a significant benefit, based only
    on the fact of nonresidence at a past point in time, clearly op-
    erates to penalize appellees for exercising their right to mi-
    grate” and thus mandated strict scrutiny. 
    Id. at 909
    .
    At bottom, the Supreme Court’s decisions in this area
    share a defining feature: each involved a rule that explicitly
    discriminated between old and new residents. As the Court
    noted in Saenz, the challenged classifications were “defined
    entirely by (a) the period of residency in California and (b) the
    location of the prior residences of the [plaintiffs].” 
    526 U.S. at 505
    . Likewise, in Soto-Lopez, the plurality emphasized that
    New York had deprived the plaintiffs “of a significant benefit,
    based only on the fact of nonresidence at a past point in time.”
    
    476 U.S. at 909
    . In each case, there has been a direct causal
    connection between a person’s status as a new resident and
    the deprivation of a benefit. In legal parlance, each involved a
    “disparate treatment” claim.
    B.
    The critical inquiry in this case is whether Indiana’s regis-
    tration requirement, as applied consistently with the Indiana
    Supreme Court’s marginal-effects test, violates the right to
    travel as it has been identified by the Supreme Court. Put an-
    other way, we ask whether SORA treats bona fide residents
    differently based on when they become residents. It does not.
    Neither SORA nor Indiana’s Ex Post Facto Clause discrim-
    inates based on residency. As a statutory matter, SORA obli-
    gates all offenders—both old and new residents—to register
    based on prior convictions. Indiana’s Ex Post Facto Clause
    No. 19-2523                                                    15
    then relieves a subset of those who must register from that
    statutory obligation. Receiving the clause’s benefits, though,
    does not depend on when an offender became an Indiana res-
    ident but on whether one is subject to an existing registration
    requirement. That requirement can come from Indiana, Jen-
    sen, 905 N.E.2d at 391–93, or from another state, Tyson, 51
    N.E.3d at 90. The twist in this case is that for those offenders
    like the plaintiffs, convicted before Indiana’s SORA covered
    their crimes, such a registration obligation must come from
    elsewhere.
    The dissent takes issue with this feature of SORA but con-
    cedes that unlike Saenz and its predecessors, SORA has nei-
    ther a durational-residency requirement nor a true, fixed-
    point residency scheme. That distinction is fatal to the plain-
    tiffs’ claim. Right to travel violations under the third compo-
    nent of the right exist only when a law expressly differentiates
    between residents based on their length or timing of resi-
    dency. SORA does neither.
    Instead, the dissent notes that SORA “does take notice of
    an individual’s treatment in another jurisdiction” and argues
    that it thus “necessarily implicates his travel history.” While
    true, that does not constitute a violation of the right to travel.
    The third component of the right—which the parties agree is
    the only aspect at issue in this appeal—deals only with dis-
    crimination based on residency. It is not triggered by every
    law that tangentially relates to a person’s travel to or from an-
    other state.
    In the absence of a true durational-residency requirement
    or any discriminatory purpose, the plaintiffs look to the effect
    of SORA on newer residents. As a practical effect of Indiana’s
    SORA, the plaintiffs argue, out-of-state residency is a
    16                                                    No. 19-2523
    determinative factor for them and similar offenders. Un-
    doubtedly having a registration obligation in another state is
    correlated with changing one’s state of residence, as we can
    see not only from the six plaintiffs here but also from those in
    Tyson, Zerbe, and Ammons, all of whom had to register after
    moving to Indiana. But the correlation is imperfect. Some life-
    long Indiana residents who committed crimes before SORA
    might well have a registration obligation based on their em-
    ployment or schooling in an adjacent state. See, e.g., 730 ILCS
    150/3(a-5) (requiring out-of-state students or employees to
    register in Illinois). The inverse is also true: some new Indiana
    residents who committed their crimes elsewhere might have
    no registration requirement in their prior state because of
    state-law protection against retroactivity. See, e.g., Doe v. State,
    
    189 P.3d 999
    , 1004 (Alaska 2008) (holding that the state’s Ex
    Post Facto Clause prohibits retroactive application of SORA).
    While prior, out-of-state residency is often an element in the
    application of SORA’s registration requirements, residency is
    not the trigger for the other-jurisdiction provision.
    The dissent acknowledges this but suggests that the law
    may still be unconstitutional even though some new residents
    are not adversely affected by SORA’s requirements. For sup-
    port, the dissent looks to Saenz. There, the Supreme Court
    struck down the law, even though some of the new residents
    received welfare benefits on equal footing as long-term Cali-
    fornians. Saenz, 
    526 U.S. at 497
    . What mattered, the Court con-
    cluded, was that California explicitly based its provision of
    benefits to new Californians—favorable or not—on the dura-
    tion of their residence in California. 
    Id. at 497, 505
    . The upshot
    of the dissent’s Saenz analogy is that SORA likewise cannot be
    saved by the fact that some new Hoosiers may not be subject
    to the registration requirements while some lifelong Hoosiers
    No. 19-2523                                                    17
    may be covered. That is a false equivalence. California em-
    ployed an express, durational-residency classification; it ap-
    plied to all persons who had resided in California for less than
    a year and happened to produce a favorable effect for some of
    them. In contrast, as the dissent admits, SORA by its terms
    does not base its application on any length of residency in In-
    diana. New Indiana residents who arrive in Indiana without
    any prior registration requirements do not experience a favor-
    able effect under SORA—the law simply does not apply to
    them at all. In sum, Saenz involved a discriminatory test that
    some new residents passed, while SORA involves a nondis-
    criminatory test that some new residents fail.
    Prior, out-of-state residency represents neither causation
    nor perfect correlation for the application of SORA’s registra-
    tion requirements, and there is no evidence that anyone in In-
    diana intended to deter travel through the other-jurisdiction
    provision. The result? Only a disparate-impact claim re-
    mains—an argument that, as a practical matter, more new res-
    idents than old residents must register under the law. The dif-
    ficulty with that approach, though, is that the Supreme Court
    has never extended the right to travel this far. Cf. Washington
    v. Davis, 
    426 U.S. 229
    , 239 (1976) (holding that only disparate
    treatment or discriminatory purpose violates the Equal Pro-
    tection Clause). To the contrary, every Supreme Court case in-
    volving a violation of the right to travel has featured a law
    that expressly imposes either a durational-residency require-
    ment or a fixed-point residency restriction. See, e.g., Saenz, 
    526 U.S. at 505
    ; Soto-Lopez, 
    476 U.S. at 905
    ; Hooper, 
    472 U.S. at
    621–
    22; Zobel, 
    457 U.S. at 57
    ; Mem’l Hosp., 
    415 U.S. at 251
    , 261–62;
    Dunn, 
    405 U.S. at
    334–35, 360. This case does not involve such
    a disparate treatment claim.
    18                                                 No. 19-2523
    The dissent’s approach thus expands the right to travel to
    an unprecedented extent. And it does so through a legal anal-
    ysis that the Court has rejected repeatedly in the analogous
    Fourteenth Amendment equal protection context. Village of
    Arlington Heights v. Metro. Hous. Dev. Corp., 
    429 U.S. 252
    , 264–
    65 (1977) (“[O]fficial action will not be held unconstitutional
    solely because it results in a racially disproportionate im-
    pact.”); see also Washington, 
    426 U.S. at 242
    . Equal protection
    jurisprudence is unequivocal: the only relevant consideration
    is a law’s express categorization and any discriminatory pur-
    pose. Crawford v. Marion Cnty. Election Bd., 
    553 U.S. 181
    , 207
    (2008) (Scalia, J., concurring).
    The Supreme Court has never indicated that the neighbor-
    ing Fourteenth Amendment Privileges or Immunities Clause
    ought to be evaluated differently, and it is difficult to justify
    such a distinction. It would be strange indeed if a law that
    created a disparate impact based on race would be subject to
    less exacting scrutiny than laws with a disparate impact on
    the right to travel. Further, one of the primary bases that the
    Supreme Court gave for rejecting disparate-impact theory—
    the potential invalidation of many neutral laws—applies with
    equal force in the right to travel context. See Washington, 
    426 U.S. at 248
     (observing that a disparate-impact approach to
    equal protection claims “would be far-reaching and would
    raise serious questions about, and perhaps invalidate, a whole
    range of tax, welfare, public service, regulatory, and licensing
    statutes”). There is no reason for permitting disparate-impact
    theory in one context but not the other, especially given how
    No. 19-2523                                                               19
    historically intertwined the Supreme Court’s right to travel
    jurisprudence has been with the Equal Protection Clause.9
    The Third Circuit has actively refused to take this step. In
    Connelly v. Steel Valley School District, 
    706 F.3d 209
     (3d Cir.
    2013), a Pennsylvania school district set its teachers’ salaries
    based on years of teaching experience but gave full credit for
    years teaching in the district, partial credit for years teaching
    in Pennsylvania, and reduced credit for years teaching else-
    where. 
    Id.
     at 211–12. A teacher who taught for nine years in
    Maryland and received one year of credit argued that the
    school district’s salary scheme violated his right to travel. 
    Id. at 213
    . The Third Circuit recognized that the district was not
    discriminating based on duration of residency but on location
    of teaching experience. 
    Id. at 214
    . A lifelong Pennsylvania res-
    ident who taught across the border in Maryland would have
    received the same treatment as a similar Maryland resident
    who moved to Pennsylvania. 
    Id.
     at 214–15. In the Third Cir-
    cuit’s view, “[t]he right to travel simply is not implicated
    when there is no discrimination based on the duration of
    one’s residency.” 
    Id. at 215
    . We agree.
    There are good reasons for limiting the right to travel to
    disparate treatment claims, as we recognized more than a dec-
    ade before Saenz. In Sklar v. Byrne, 
    727 F.2d 633
     (7th Cir. 1984),
    we rejected the suggestion that laws with a disproportionate
    impact on new residents violate the right to travel. Sklar pre-
    sented a right to travel objection to an ordinance banning
    9 Recall that prior to Saenz, the Supreme Court often positioned the
    right to travel within the Equal Protection Clause. See Zobel, 
    457 U.S. at
    60
    n.6.
    20                                                   No. 19-2523
    unregistered handguns in the City of Chicago. Because one
    needed to be a Chicago resident to register a handgun for law-
    ful possession—and Chicago stopped new registrations after
    1982—Sklar argued that the ordinance violated the right to
    travel. 
    Id.
     We explained then that this could not be how the
    right to travel functions, for applying strict scrutiny “based
    merely on a showing that newer residents would not benefit”
    would make huge swaths of the law vulnerable. Id. at 639. As
    in Sklar, the plaintiffs here want to apply strict scrutiny on the
    showing that they, as new residents, are “merely one group
    among several who do not benefit” from the protections of
    Indiana’s Ex Post Facto Clause. Id. at 639. We refused the in-
    vitation in 1984 and decline it again today.
    The Privileges or Immunities Clause of the Fourteenth
    Amendment simply does not prohibit a state from inci-
    dentally burdening travel to or from the state. It guarantees
    only “the right of the newly arrived citizen to the same privi-
    leges and immunities enjoyed by other citizens of the same
    State.” Saenz, 
    526 U.S. at 502
    . Because both old and new Indi-
    ana residents are treated equally under SORA and Indiana’s
    Ex Post Facto Clause, we hold that the law does not violate
    plaintiffs’ right to travel.
    III.
    The plaintiffs’ equal protection claim is closely inter-
    twined with their right to travel claim, but it remains distinct.
    Equal protection and right to travel claims require independ-
    ent analyses—even when the basis for the claims is identical.
    Under the Privileges or Immunities Clause, if the right to
    travel is not implicated, that is the end of the plaintiffs’ claim.
    The challenged law either is reviewed under strict scrutiny or
    not at all. Under the Equal Protection Clause, by contrast,
    No. 19-2523                                                    21
    failure to trigger heightened scrutiny does not end the claim.
    Courts still review the challenged law to ensure that the state
    has a rational basis for treating similarly situated people dif-
    ferently. FCC v. Beach Commc’ns, Inc., 
    508 U.S. 307
    , 313 (1993).
    The Fourteenth Amendment’s Equal Protection Clause
    guarantees that “No State shall . . . deny to any person within
    its jurisdiction the equal protection of the laws.” U.S. Const.
    amend. XIV, § 1. Unlike the right to travel, which requires
    strict scrutiny when implicated, the standard of review ap-
    plied to laws in equal protection cases varies. We apply strict
    scrutiny to a law if the plaintiffs’ unequal treatment is based
    on membership in a protected class—race, national origin, re-
    ligion, or alienage—or denial of a fundamental right. St. Joan
    Antida High Sch. Inc. v. Milwaukee Pub. Sch. Dist., 
    919 F.3d 1003
    ,
    1008 (7th Cir. 2019). When a plaintiff’s unequal treatment is
    premised on a quasi-suspect classification, like gender, we ap-
    ply intermediate scrutiny. 
    Id.
     at 1008 n.3. In all other cases,
    courts default to rational basis review. 
    Id. at 1008
    .
    Here, plaintiffs argue that the district court correctly ap-
    plied strict scrutiny when it evaluated SORA. That is because
    their equal protection theory assumes that SORA violates a
    fundamental right—the right to travel. We have already held
    that it does not. SORA treats the plaintiffs differently from
    other, pre-SORA offenders based on their out-of-state regis-
    tration requirements—not based on their length of residency.
    Because Indiana’s treatment of the plaintiffs is not based on
    their membership in a protected class or the denial of a fun-
    damental right, strict scrutiny is inapplicable. Nor does inter-
    mediate scrutiny apply. Neither gender nor any other quasi-
    suspect class serves as the catalyst for the plaintiffs’ differen-
    tial treatment under SORA.
    22                                                    No. 19-2523
    Our determination that heightened scrutiny is inapplica-
    ble is not fatal to their equal protection claim, however. It just
    means that SORA will be assessed under rational basis re-
    view. The plaintiffs may still challenge Indiana’s application
    of SORA to them because it treats them differently than simi-
    larly situated Indiana offenders. SORA, as modified by the In-
    diana Supreme Court’s constitutional overlay, creates two
    classes of pre-SORA offenders—those who must register in
    Indiana, and those who are free from that requirement. Indi-
    ana distinguishes between the two groups based solely on
    whether the pre-SORA offender had a registration obligation
    in another state. For example: two lifelong Indiana residents,
    both with pre-SORA convictions, will be treated differently if
    one commutes into Chicago for work—and so is subject to Il-
    linois’s reporting requirements—while the other never leaves
    Indiana. The distinction holds true for offenders who attend
    school in another state or who have lived in another state im-
    posing registration obligations on them. In short, two simi-
    larly situated Indiana offenders may have vastly different le-
    gal obligations simply because one of them has an out-of-state
    registration obligation. The question is whether Indiana’s dif-
    ferential treatment on this basis is rationally related to a legit-
    imate government purpose. See Armour v. City of Indianapolis,
    Ind., 
    566 U.S. 673
    , 680 (2012); FCC, 
    508 U.S. at 313
     (“[A] statu-
    tory classification that neither proceeds along suspect lines
    nor infringes fundamental constitutional rights must be up-
    held against equal protection challenge if there is any reason-
    ably conceivable state of facts that could provide a rational
    basis for the classification.”).
    Because the district court did not address whether SORA
    satisfies rational basis review, we remand the equal protection
    claim for this purpose. In doing so, we stress that this review
    No. 19-2523                                                    23
    should be undertaken with care and that the district court
    should thoroughly develop the factual record on this score.
    Rational basis review favors the State but does not ensure an
    automatic win. See, e.g., Allegheny Pittsburgh Coal Co. v. Cnty.
    Comm’n, 
    488 U.S. 336
     (1989) (invalidating a tax assessment on
    equal protection grounds for failing rational basis review).
    IV.
    The plaintiffs’ final claim is an ex post facto challenge to
    SORA. Because we determine that SORA is not a punitive
    statute, it does not violate the federal Ex Post Facto Clause.
    Article I, section 10, clause 1 of the United States Constitu-
    tion prohibits states from passing ex post facto laws—those
    which “retroactively alter the definition of crimes or increase
    the punishment for criminal acts.” Cal. Dep’t of Corr. v. Mo-
    rales, 
    514 U.S. 499
    , 504 (1995) (quoting Calder v. Bull, 3 U.S.
    (Dall.) 386, 391–92 (1798)). Statutes that transgress the Ex Post
    Facto Clause, then, share two characteristics: They are “both
    retroactive and penal.” Vasquez v. Foxx, 
    895 F.3d 515
    , 520 (7th
    Cir. 2018); see also Johnson v. United States, 
    529 U.S. 694
    , 699
    (2000).
    There is tension in the caselaw regarding the requirements
    of the retroactivity prong. Compare United States v. Leach, 
    639 F.3d 769
    , 773 (7th Cir. 2011) (deciding that SORAs are pro-
    spective regardless of their reach because they “merely cre-
    ate[] new, prospective legal obligations based on the person’s
    prior history”), with Does #1-5 v. Snyder, 
    834 F.3d 696
    , 698 (6th
    Cir. 2016) (holding Michigan’s version of SORA retroactive
    because it applied to offenders convicted prior to the law’s
    enactment), and Shaw v. Patton, 
    823 F.3d 556
    , 560 (10th Cir.
    2016) (holding the same with respect to Oklahoma’s version
    24                                                    No. 19-2523
    of SORA). While we recognize this tension, we need not—and
    do not—revisit our decisions on retroactivity at this time.
    Here, the plaintiffs did not ask us to overrule our prior deci-
    sions, and their ex post facto challenge fails regardless be-
    cause SORA is not punitive.
    In determining whether a statute is punitive, Smith v. Doe
    is our guidepost. There, the Supreme Court addressed
    whether Alaska’s sex offender registration and notification
    law violated the federal Ex Post Facto Clause. The Court ap-
    plied what is commonly called the intent-effects test to hold
    that Alaska’s sex offender registration act was not punitive.
    Smith, 
    538 U.S. at
    105–06. Applying that two-step standard,
    courts first query whether the legislature intended to enact a
    punitive, rather than a civil, law. If not, the inquiry becomes
    whether the law is “so punitive either in purpose or effect as
    to negate [the State’s] intention to deem it civil.” 
    Id. at 92
     (in-
    ternal quotation and citation omitted). To assess a law’s ef-
    fects, Smith considered five of the factors originally articulated
    in Kennedy v. Mendoza-Martinez, 
    372 U.S. 144
     (1963). Those fac-
    tors are “whether, in its necessary operation, the regulatory
    scheme: [1] has been regarded in our history and traditions as
    a punishment; [2] imposes an affirmative disability or re-
    straint; [3] promotes the traditional aims of punishment; [4]
    has a rational connection to a nonpunitive purpose; or [5] is
    excessive with respect to this purpose.” Smith,

    .
    This is a challenging standard for plaintiffs. When as-
    sessing whether a law is punitive, “we ordinarily defer to the
    legislature’s stated intent.” Kansas v. Hendricks, 
    521 U.S. 346
    ,
    361 (1997). If the legislative intent is to enact a civil law, only
    the “clearest proof that the statutory scheme is so punitive in
    either purpose or effect” will suffice to override it. Seling v.
    No. 19-2523                                                  25
    Young, 
    531 U.S. 250
    , 261 (2001); Hudson v. United States, 
    522 U.S. 93
    , 104 (1997); see also Smith, 
    538 U.S. at 92
    .
    The plaintiffs have conceded that Indiana intended to en-
    act a civil, regulatory scheme when it passed SORA. We thus
    consider only whether SORA is so punitive in effect as to over-
    ride Indiana’s nonpunitive intent. To that end, we address the
    Mendoza-Martinez factors in turn.
    1. Historical and traditional forms of punishment
    Plaintiffs present three historical forms of punishment—
    shaming, banishment, and parole/probation—and argue that
    SORA’s requirements are tantamount to these sanctions. All
    three comparators suffer the same infirmity: SORA does not
    actually inflict what is historically and traditionally consid-
    ered punishment.
    The plaintiffs first argue that SORA’s publication of their
    classifications—such as “sexually violent offender” or “of-
    fender against children”—is “designed to outrage” and stig-
    matizes without a present assessment of individual danger-
    ousness. In this regard, SORA goes further than the statute in
    Smith, which assigned no categorical labels to offenders. But
    SORA’s classification scheme falls short of public shaming for
    the same reason as the Alaska statute in Smith. Indiana classi-
    fies offenders based on offense type and in doing so, transmits
    accurate information about the underlying conviction—a
    matter of public record. To the extent that stigma results, it
    arises “not from public display for ridicule and shaming but
    from the dissemination of accurate information about a crim-
    inal record.” Smith, 
    538 U.S. at 98
    . But see Does #1-5, 834 F.3d
    at 703 (concluding that the “ignominy” results from the stat-
    ute’s application of labels, not from conviction information).
    26                                                         No. 19-2523
    The plaintiffs also suggest that SORA’s residency re-
    strictions are akin to banishment, but we rejected this asser-
    tion when evaluating the Illinois sex offender registration
    statute. Vasquez, 895 F.3d at 521. We reasoned that although
    residency restrictions limit offenders’ living and employment
    options, they do not amount to banishment—which tradition-
    ally meant that persons “could neither return to their original
    community nor … be admitted easily into a new one.” Id. (in-
    ternal quotation and citation omitted). The plaintiffs
    acknowledge our precedent but note that the Indiana re-
    striction is 500 feet greater than the Illinois restriction. The dif-
    ference between a 500- and 1,000-foot residency restriction is
    not constitutionally significant, however, because it does not
    render SORA’s requirements any more similar to banishment.
    Lastly, the plaintiffs contend that SORA’s restrictions on
    where they may live or work, in tandem with its in-person
    reporting requirements, make it analogous to parole or pro-
    bation. This is a closer call. In Smith, the Supreme Court
    acknowledged that a comparison between the Alaska statute
    and parole “has some force.” Smith, 
    538 U.S. at 101
    . Even so,
    the Court held that the statute was distinguishable because it
    lacked two key characteristics of parole: (1) mandatory condi-
    tions, and (2) the option for a supervisor “to seek the revoca-
    tion of probation or release in case of infraction.” 
    Id.
     The Court
    emphasized that Alaska’s reporting requirements were not
    in-person and that offenders could “move where they wish”
    and live and work without supervision. 
    Id.
     SORA differs from
    the Alaska statute on these points.10 We conclude, however,
    10
    While SORA employs mechanisms like those used in parole and
    probation, we note that it does not subject offenders to the same degree of
    No. 19-2523                                                               27
    that it is still distinct from parole because it lacks the second
    defining feature of parole discussed by Smith. To be sure,
    plaintiffs may face criminal prosecution for failure to comply
    with reporting requirements. But that would be a conse-
    quence distinct from the plaintiffs’ original offenses; parole
    and the supervisor’s ability to seek revocation of it are tied to
    the terms of the original offense. A sex offender who violates
    SORA is not subject to revocation—but rather a new criminal
    prosecution for violating state law. Shaw, 823 F.3d at 566. But
    see Snyder, 834 F.3d at 703. Thus, a sex offender covered by
    SORA is not under the same type of supervision as a parolee.
    On balance, SORA’s requirements do not amount to tradi-
    tional forms of punishment. So, this factor, while close, tips in
    favor of Indiana.
    2. Affirmative disabilities or restraints
    The next factor considers whether SORA subjects the
    plaintiffs to an “affirmative disability or restraint.” Mendoza-
    Martinez, 
    372 U.S. at 168
    . The boundaries of this factor are un-
    defined. The Alaska law in Smith required offenders to regis-
    ter and mandated reporting of any changes to facial features
    or plans to borrow a car or procure psychiatric treatment.
    Smith, 
    538 U.S. at 101
    . The Court held that these requirements
    scrutiny or control. See Vasquez, 895 F.3d at 521 (concluding that Illinois’s
    SORA, despite limiting where offenders could live, did not resemble the
    “comprehensive control” of probation). For example, SORA entails some
    supervision—law enforcement officers must do annual check-ins to verify
    an offender’s physical address—but this differs in degree and type from
    the monitoring of parolees and probationers. See Shaw, 823 F.3d at 564–65
    (“Historically, a probation officer took a far more active role in a proba-
    tioner’s life than simply collecting information for a database.”).
    28                                                  No. 19-2523
    “make a valid regulatory program effective and do not im-
    pose punitive restraints.” Id. at 102. In doing so, the Court un-
    derscored that the statute “imposes no physical restraint, and
    so does not resemble the punishment of imprisonment, which
    is the paradigmatic affirmative disability or restraint.” Id. at
    100. It also emphasized that the “Act’s obligations are less
    harsh than the sanctions of occupational debarment, which
    we have held to be nonpunitive.” Id. While the Court ob-
    served that Alaska’s SORA did not require in-person report-
    ing or restrict offenders’ ability to change jobs or residences,
    the Court gave no indication whether such requirements
    would constitute punitive disabilities or restraints. Id. at 100–
    01.
    Outside the “paradigmatic” example of physical restraint,
    it is not evident what statutory requirements amount to a re-
    straint or disability. What is clear is that very few burdens are
    significant enough to tip the scale. See, e.g., Hudson, 
    522 U.S. at 104
     (monetary fine and occupational debarment are not af-
    firmative disabilities or restraints “as that term is normally
    understood”); Flemming v. Nestor, 
    363 U.S. 603
    , 617 (1960) (de-
    nial of a noncontractual government benefit is not an affirma-
    tive disability or restraint); see also Vasquez, 895 F.3d at 522
    (“[L]ike the registration scheme at issue in Smith, the resi-
    dency law imposes no physical restraint[] and so does not re-
    semble the punishment of imprisonment, which is the para-
    digmatic affirmative disability or restraint.” (internal quota-
    tion and citation omitted)). Even when the Supreme Court
    confronted a state law imposing a paradigmatic form of re-
    straint—involuntary confinement—the Court held that this
    did not make the law punitive. Hendricks, 
    521 U.S. at 363
    .
    Here, it is sufficient to note that to the extent that SORA’s ob-
    ligations amount to restraints or disabilities, standing alone
    No. 19-2523                                                   29
    they are not sufficiently severe in view of Supreme Court
    precedent to make SORA punitive.
    3. Promotion of traditional aims of punishment
    Plaintiffs next suggest that SORA has punitive aims—spe-
    cifically, incapacitation, deterrence, and retribution. The Su-
    preme Court has rejected these arguments in the context of
    other sex offender registration laws, however. See, e.g., Smith,
    
    538 U.S. at 102
     (“Any number of governmental programs
    might deter crime without imposing punishment.”); Hudson,
    
    522 U.S. at
    104–05 (holding that the involuntary commitment
    of a child sex offender was not retributive because prior con-
    viction was used as evidence of future dangerousness, not to
    assign culpability). We similarly were unpersuaded that the
    residency restrictions at issue in Vasquez furthered traditional
    punitive aims in lieu of the Illinois SORA’s “obvious aim” to
    “protect children.” Vasquez, 895 F.3d at 522. The Sixth Circuit
    has also “accordingly give[n] this factor little weight,” recog-
    nizing that civil statutes often pursue these aims, too. Does #1-
    5, 834 F.3d at 704. Because the plaintiffs have failed to show
    why the analyses in these cases do not apply with equal force
    to the same arguments that they raise here, this factor favors
    Indiana.
    4. Rational connection to a nonpunitive purpose
    Whether the law has a “rational connection to a nonpuni-
    tive purpose” is “a most significant factor in our determina-
    tion that the statute’s effects” are not punitive. Smith, 
    538 U.S. at 102
     (internal quotation and citation omitted). We begin by
    identifying a nonpunitive purpose and then turn to whether
    the law’s requirements are rationally connected to that goal.
    30                                                 No. 19-2523
    One aim of SORA is to advance public safety, particularly
    for vulnerable minors. See Smith, 
    538 U.S. at 93
     (“[A]n impo-
    sition of restrictive measures on sex offenders adjudged to be
    dangerous is a legitimate nonpunitive governmental objective
    and has been historically so regarded.” (internal quotation
    and citation omitted)). No one disputes this nonpunitive pur-
    pose. The disagreement centers instead on whether SORA’s
    requirements are rationally related to that aim. We are satis-
    fied that they are.
    Laws that result in consequences for offenders’ prior con-
    duct are not automatically punitive if they are connected to a
    regulatory purpose that falls within the power of the state,
    such as public safety. Flemming, 
    363 U.S. at 616
    . Deportation,
    for example, is “an exercise of the plenary [power] of Con-
    gress to fix the conditions under which aliens are permitted to
    enter and remain in this country.” 
    Id.
     While it presents a con-
    sequence for people who have unlawfully entered the United
    States, that does not convert a lawful exercise of congressional
    power into a punishment. Similarly, the Supreme Court has
    held that excluding former felons from practicing a profession
    “is an incident of the State’s power to protect the health and
    safety of its citizens”—“not a purpose to add to the punish-
    ment of ex-felons.” 
    Id.
     So, too, here. SORA’s registration re-
    quirements rationally relate to Indiana’s power to protect the
    safety of its citizens, despite its burden on sex offenders. See
    Shaw, 823 F.3d at 572 (explaining that Oklahoma’s “reporting
    requirements are also consistent with a non-punitive intent—
    promoting public safety—by facilitating law enforcement’s
    identification of sex offenders and notification to the public of
    potential dangers”). This critical factor supports Indiana.
    No. 19-2523                                                       31
    5. Excessive with respect to that purpose
    The touchpoint for the excessiveness factor is “whether the
    regulatory means chosen are reasonable in light of the nonpu-
    nitive objective,” not whether “the legislature has made the
    best choice possible to address the problem it seeks to rem-
    edy.” Smith, 
    538 U.S. at 105
    . The burden is on the plaintiff to
    establish that the law’s “nonpunitive purpose is a sham or
    mere pretext.” 
    Id. at 103
     (internal quotation and citation omit-
    ted).
    While the plaintiffs proffer several arguments on this fac-
    tor, they fall short of meeting their burden. First, they contend
    that SORA does not further its goal, making its requirements
    excessive. The plaintiffs cite a study showing that sex offend-
    ers do not recidivate at higher rates than other felons. The im-
    plication is that SORA’s registration requirements will not
    bolster public safety because sex offenders do not present an
    outsized threat. This conclusion is flawed. The plaintiffs’
    study does not establish that sex offenders pose little risk to
    the public, just that their risk of reoffending is similar to that
    of other ex-felons. See Vasquez, 895 F.3d at 522 (“[S]imilar re-
    cidivism rates across different categories of crime would not
    establish that the nonpunitive aim of this statute—protecting
    children—is a sham.”).
    The plaintiffs also take issue with SORA’s application to
    all offenders “without regard to their future dangerousness.”
    But the Supreme Court “has upheld against ex post facto chal-
    lenges laws imposing regulatory burdens on individuals con-
    victed of crimes without any corresponding risk assessment.”
    Smith, 
    538 U.S. at 104
    ; see, e.g., De Veau v. Braisted, 
    363 U.S. 144
    ,
    159–60 (1960) (plurality opinion) (upholding a law that pro-
    hibited former felons from working as union officers).
    32                                                 No. 19-2523
    Although Smith recognized that the “magnitude of the re-
    straint” could require individual assessments in some cases,
    such cases are the exception. Smith, 
    538 U.S. at 104
     (discussing
    the involuntary and potentially indefinite confinement at is-
    sue in Hendricks as one example). Indiana is not required to
    make individualized judgments before imposing its registra-
    tion requirements. This factor favors Indiana.
    ***
    At best, the plaintiffs have shown that SORA partially re-
    sembles one historical punishment and may place some af-
    firmative restraints or disabilities on them. The remaining fac-
    tors, including the law’s rational relation to a nonpunitive
    purpose, all support Indiana. The plaintiffs have not carried
    their heavy burden of proving that SORA is so punitive in ef-
    fect as to override the Indiana legislature’s intent to enact a
    civil law. As the plaintiffs acknowledge, “the Alaska statute at
    issue in [Smith] shares several core provisions with Indiana’s
    SORA.” While SORA goes farther than the Alaska law in
    some respects, it is not so far afield as to warrant a different
    outcome than in Smith.
    V.
    We hold that Indiana’s SORA neither violates plaintiffs’
    right to travel nor constitutes an impermissible ex post facto
    law. Accordingly, we reverse the district court’s entry of sum-
    mary judgment and remand for further analysis of the equal
    protection claim consistent with this opinion.
    REVERSED AND REMANDED
    No. 19-2523                                                    33
    SCUDDER, Circuit Judge, concurring. I join the majority
    opinion and write separately to address one aspect of the
    opinion—the retroactivity inquiry of the Ex Post Facto Clause.
    Our case law on the retroactivity prong needs a course cor-
    rection. See Vasquez v. Foxx, 
    895 F.3d 515
     (7th Cir. 2018); United
    States v. Leach, 
    639 F.3d 769
     (7th Cir. 2011). The pertinent ret-
    roactivity inquiry is whether the law “imposes a punishment
    for an act which was not punishable at the time it was com-
    mitted; or imposes additional punishment to that then pre-
    scribed.” Carmell v. Texas, 
    529 U.S. 513
    , 540 (2000) (quoting
    Cummings v. Missouri, 
    71 U.S. 277
    , 325–26 (1867) (internal quo-
    tation marks omitted)).
    But in Leach we suggested otherwise, determining that the
    federal SORNA was not impermissibly retroactive because it
    “merely creates new, prospective legal obligations based on
    the person’s prior history.” 
    639 F.3d at 773
    ; see also Vasquez,
    895 F.3d at 520 (applying Leach’s retroactivity holding to Illi-
    nois’s SORA). Though this observation about how SORNA
    functions is descriptively correct, it misses the mark on the
    retroactivity inquiry. What Leach and Vasquez failed to account
    for is that the registration obligations did not apply at the time
    the sex offenders committed the offenses triggering registra-
    tion—meaning that the sex offender registration laws im-
    posed obligations beyond those prescribed at the time of the
    offense.
    The majority opinion acknowledges this tension in our
    case law but stops short of fixing it. See Maj. Op. 23. I would
    take the next step and use today’s decision to align our law
    with Supreme Court precedent. The issue is sure to surface in
    future cases and our sitting en banc provides the perfect op-
    portunity for the full court to issue the course correction.
    34                                                No. 19-2523
    There is no question that the obligations imposed by Indiana’s
    SORA on the six plaintiffs in this case apply retroactively, and
    we should use today’s decision to say so.
    No. 19-2523                                                                    35
    ROVNER, Circuit Judge, with whom WOOD and HAMILTON,
    Circuit Judges, join, concurring in part and dissenting in part.
    I join all but Part II of the court’s opinion today. I remain con-
    vinced that Indiana’s other jurisdiction provision 1 deprives
    the plaintiffs of state citizenship on equal terms with other In-
    diana residents and in so doing violates their right to travel. I
    therefore dissent from that part of the court’s decision.
    1.
    Encompassed within the right to travel is the right to relo-
    cate from one state to another and, upon establishing bona
    fide residence in a new state, to enjoy the same privileges and
    immunities as any other citizen of that state. Saenz v. Roe, 
    526 U.S. 489
    , 502, 
    119 S. Ct. 1518
    , 1526 (1999). Each of the six plain-
    tiffs in this case has been denied the benefit of Indiana’s ex post
    facto provision 2 that a similarly-situated, but lifelong Indiana
    resident would receive. Because each of the plaintiffs commit-
    ted a sex offense before Indiana attached a registration obli-
    gation to that crime, the Indiana Supreme Court’s decision in
    Wallace precludes the State from relying on their convictions
    as the basis for requiring them to register. Wallace v. State, 
    905 N.E.2d 371
    , 384 (Ind. 2009). What Indiana has done instead is
    to rely on the fact that each of the plaintiffs previously was
    required to register in another state as the basis for imposing
    its own registration obligation on them. Had any of the
    1 See 
    Ind. Code § 11-8-8-4
    .5(b)(1) (defining “sex offender” who must
    register in Indiana to include “a person who is required to register as a sex
    offender in any jurisdiction”); § 11-8-8-5(b)(1) (similarly defining “sex or
    violent offender” who must register).
    2   Ind. Const., art. 1, § 24 (“No ex post facto law … shall ever be passed.”).
    36                                                               No. 19-2523
    plaintiffs been a resident of Indiana at the time of his offense
    and never traveled anywhere that burdened him with a duty
    to register, Indiana itself would not have imposed such a bur-
    den on him. It is thus only their travel—in this case, relocation
    from another state to Indiana—that renders them subject to a
    registration obligation in Indiana. This sets up the very sort of
    tiered classes of state citizenship that the Supreme Court’s
    travel jurisprudence forbids. 3 The fact that a lifelong Indiana
    resident may also incur an obligation to register in Indiana by
    working or studying in another state that imposes such a duty
    on him does not obviate the problem; it simply makes clear
    that Indiana is relying on the fortuity of a person’s travel to
    burden its citizen with an obligation that it would not other-
    wise impose.
    At bottom, what Indiana is doing is assigning differential
    obligations to its citizens based not on what they have done
    but where they have been. It is relying on another state’s han-
    dling of a particular criminal history to determine how that
    3 The number of individuals who can assert the particular right-to-
    travel claim the plaintiffs are asserting in this case is necessarily limited
    and dwindling. Anyone convicted of a sex offense since the mid-1990s or
    later (i.e., after registration requirements were first adopted in Indiana and
    elsewhere) will likely be subject to registration in Indiana based on their
    criminal histories. Wallace only poses an obstacle to imposing registration
    obligations on someone convicted before Indiana made his crime (or its
    out-of-state equivalent) a registrable offense. So, with respect to the vast
    majority of offenders, Indiana will not have to rely on the other jurisdic-
    tion requirement as it must with respect to the six plaintiffs in this case, all
    of whom were convicted in 1994 or earlier and are now in their fifties or
    sixties.
    No. 19-2523                                                     37
    individual will be treated in Indiana. So a sex offender whose
    crime would not otherwise trigger a registration obligation as
    a matter of Indiana law will nonetheless be required to regis-
    ter because another state, as a matter of its own law, required
    him to register so long as he lived, worked, or studied in that
    state. Indiana thus is relying on another state’s legal rules to
    circumscribe his rights as an Indiana citizen. This is incompat-
    ible with the holdings and the logic of the Supreme Court’s
    right-to-travel cases.
    2.
    One point should be made clear at the outset: In taking
    notice that another state has imposed a registration obligation
    on one of its citizens, Indiana is not purporting to enforce an-
    other state’s judgment or to implement the registration obli-
    gation that state has imposed. This would be a very different
    case if that were the aim and effect of Indiana’s other jurisdic-
    tion provision. But it is not. Indiana instead is relying on the
    historical fact that another state required an offender to regis-
    ter there (whenever and for however long) as the basis for im-
    posing its own registration obligation on one of its citizens. See
    State v. Zerbe, 
    50 N.E.3d 368
    , 370 (Ind. 2016) (“it is not Zerbe’s
    crime that triggers his obligation to register as a sex offender
    in Indiana; rather it is his Michigan registry requirement that
    does so”) (emphasis in original). This new obligation is not in
    any way tethered to the life of the registration obligation im-
    posed by the other state. It is not as if, for example, an offender
    who was required by California to register for a period of 10
    years and seven years into that obligation moves to Indiana
    will now have to register for an additional three years in In-
    diana in order to complete the 10-year term that California
    imposed. It does not matter to Indiana’s other jurisdiction
    38                                                   No. 19-2523
    provision for how long an offender was required to register
    in another state or when that obligation expires. It only mat-
    ters to Indiana’s registration scheme that there was a prior ob-
    ligation, period. And how lengthy the new registration obli-
    gation will be in Indiana is a matter answered by Indiana law.
    Thus, whereas the other state may only have required an of-
    fender to register for a period of years, Indiana may require
    him to register for the remainder of his life. Take plaintiff Pat-
    rick Rice, for example. Based on his 1989 conviction for aggra-
    vated sexual assault, Rice was required by Illinois to register
    for a period of 10 years upon his release from prison in 2017,
    but when he subsequently relocated to Indiana to live with
    his sister, Indiana imposed a lifetime registration obligation
    on him, because his Illinois offense makes him a “sexually vi-
    olent predator” under Indiana law. Cf. Jensen v. State, 
    905 N.E.2d 384
    , 394 (Ind. 2009) (statutory revisions to registration
    scheme which have effect of lengthening Indiana offender’s
    existing registration obligation from 10 years to life do not
    amount to ex post facto violation).
    So in no sense is this case one about the enforceability of
    another state’s judgment or the comity that Indiana must af-
    ford to that judgment. Indiana is simply relying on an of-
    fender’s registration history in another state as the basis for
    implementing its own, independent duty to register in Indi-
    ana. And it is doing so in circumstances where the offender’s
    criminal history itself would not trigger a registration obliga-
    tion as a matter of Indiana law.
    Over the course of this litigation, Indiana has cited two re-
    lated reasons for relying on a prior registration obligation im-
    posed elsewhere as the basis for imposing a duty to register
    in Indiana. First, Indiana is concerned that it not become a
    No. 19-2523                                                    39
    haven for sex offenders who, like the plaintiffs here, commit-
    ted sex offenses before those offenses became subject to regis-
    tration in Indiana and whom the state, under Wallace, cannot
    require to register based on that criminal history. Second, In-
    diana is using the other jurisdiction requirement as a second-
    ary, catchall criterion for requiring registration of individuals
    whose particular crimes happen not to fall within any of the
    categories of offenses that the Indiana legislature has thus far
    identified as crimes requiring registration.
    It goes without saying that Indiana has a legitimate inter-
    est in implementing registration obligations as a means of
    protecting its citizenry from individuals who might repeat
    their prior sex offenses. I can also appreciate the state’s wish
    not to allow an offender to escape a duty to register in Indiana
    simply because his specific sex offense is not one that the leg-
    islature thought to identify in the drafting process as one war-
    ranting registration. But see Edwards v. California, 
    314 U.S. 160
    ,
    173, 
    62 S. Ct. 164
    , 167 (1941) (“no boundar[y] to the permissi-
    ble area of State legislative activity … is more certain than the
    prohibition against attempts on the part of any single State to
    isolate itself from difficulties common to all of them by re-
    straining the transportation of persons and property across its
    borders”); Shapiro v. Thompson, 
    394 U.S. 618
    , 629, 
    89 S. Ct. 1322
    ,
    1329 (1969) (“the purpose of inhibiting migration by needy
    persons into the State is constitutionally impermissible”),
    overruled in part on other grounds by Edelman v. Jordan, 
    415 U.S. 651
    , 671, 
    94 S. Ct. 1347
    , 1359–60 (1974).
    But Indiana is among a minority of jurisdictions that re-
    gards sex offender registration as punitive and thus subject to
    40                                                              No. 19-2523
    the ex post facto clause of its constitution. 4 Thus, as a matter of
    its own law, Indiana cannot require the six plaintiffs in this
    case to register based solely on their criminal histories, as the
    plaintiffs committed their crimes before the state legislature
    first made them registrable offenses. Wallace precludes the
    state from effectively increasing their punishment after the
    fact.
    By looking instead to a registration obligation imposed by
    another state as the basis for imposing its own obligation on
    the plaintiffs, Indiana nominally avoids the ex post facto prob-
    lem. 5 But in doing so, it has created another, federal
    Some eight state supreme courts have held that the retroactive appli-
    4
    cation of sex offender registration and notification laws violate their re-
    spective state constitutions. See U.S. Dep’t of Justice, Office of Justice Pro-
    grams, Office of Sex Offender Sentencing, Monitoring, Apprehending,
    Registering, & Tracking, Sex Offender Registration and Notification in the
    United States, Current Case Law and Issues—March 2019: Retroactive Applica-
    tion & Ex Post Facto Considerations, at 1–2 & n.9, available at
    https://smart.ojp.gov/sorna/current-law/case-law-updates.
    5I say nominally because the rationale of the Indiana cases is that In-
    diana is premising its registration obligation solely upon the obligation
    imposed by the offender’s former domicile and not on his underlying
    criminal offense, e.g., Zerbe, 50 N.E.3d at 370, with the result that his obli-
    gation to register is effectively continued across state lines, Tyson v. State,
    
    51 N.E.3d 88
    , 96 (Ind. 2016). (Of course, there would have been no duty to
    register in the first instance but for the particular offense he committed,
    and that offense would not trigger a duty to register under Indiana law.)
    I am not confident this rationale holds up in all applications of Indiana’s
    other jurisdiction requirement, however. Two of the plaintiffs, Gary
    Snider and Adam Bash, relocated to Indiana three and six years, respec-
    tively, before the Indiana legislature adopted the other jurisdiction provi-
    sion in 2006. Although they had been required to register in their former
    domiciles, those registration obligations would have effectively come to
    an end once they moved to Indiana, at least absent an assertion of
    No. 19-2523                                                               41
    constitutional problem. Relying on an obligation that another
    state has imposed as a matter of its own law as the determi-
    nant for how a new Indiana citizen will be treated in Indiana
    interferes with his right to travel. It is only because each plain-
    tiff lived somewhere else previously that he can now be re-
    quired to register as a matter of Indiana law. And upon their
    relocation to Indiana each finds his rights vis-à-vis registra-
    tion defined by his former domicile: only because he once
    lived somewhere that authorized registration for his offense
    may he be required to register in Indiana, whose own law
    would not have permitted a registration obligation based on
    the very same criminal history. See Saenz,

    3.
    My colleagues in the majority characterize the effect of the
    other jurisdiction provision on the plaintiffs as merely one of
    disparate impact rather than one of disparate treatment. It is
    true enough that the statute does not draw express distinc-
    tions based on a person’s residency. But the statute on its face
    does take notice of an individual’s treatment in another juris-
    diction and uses his treatment elsewhere as the template for
    how he will now be treated as an Indiana citizen, under Indi-
    ana law. In doing so, the statute necessarily implicates his
    travel history. More to the point, it creates distinct classes of
    Indiana citizenship that turn upon what rights and obliga-
    tions an individual has been assigned by another state. In
    some instances, the effect is benign; in others, the individual
    loses important freedoms he would have enjoyed as an Indi-
    ana citizen had he never relocated from or traveled to another
    state. In all applications of the statutory provision at issue
    here, it is the person’s travel history, and his treatment in an-
    other jurisdiction, that define his rights as an Indiana citizen
    going forward. The burdens that the plaintiffs in this case, and
    other Indiana offenders like them, must shoulder as a result
    of the other jurisdiction provision are not the unintended con-
    sequence of a statute that is otherwise neutral vis-à-vis the
    right to travel. The very purpose of the statute is to use the
    fact of one’s prior presence in another jurisdiction to circum-
    scribe his rights as an Indiana citizen. This is not disparate im-
    pact. It is, overtly and unmistakably, disparate treatment. Alt-
    hough the Supreme Court has not yet confronted the particu-
    lar fact pattern presented here, its teachings show us why
    No. 19-2523                                                       43
    Indiana’s registration scheme unconstitutionally burdens the
    plaintiffs’ right to travel.
    4.
    The majority relies on two features of Indiana’s other ju-
    risdiction provision to distinguish it from the sorts of dura-
    tional residency schemes that the Supreme Court has deemed
    to violate the right to travel. First, if a sex offender relocates to
    Indiana from another state that did not require him to regis-
    ter, Indiana’s other jurisdiction provision will not by its terms
    compel him to register in Indiana. Second, relocating to Indi-
    ana is not the only way of triggering the other jurisdiction
    provision: The provision also comes into play when an Indi-
    ana resident—however longstanding—travels to another
    state for work or study (while remaining an Indiana resident)
    and is required to register in that state so long as he is present
    for those purposes. To the majority’s way of thinking, these
    provisions show that Indiana is not discriminating based on
    the length of one’s residency in Indiana, as has typically been
    the case in the Supreme Court’s jurisprudence.
    Certainly the timing and duration of one’s residency in In-
    diana is not the sole determinant of whether its other jurisdic-
    tion provision will compel him to register as a sex offender in
    Indiana. If anything, however, the way in which Indiana’s
    other jurisdiction provision operates makes plain that Indiana
    is relying exclusively on how one was treated in another state
    to determine how he will be treated in Indiana. This cannot
    be reconciled with what I understand to be the animating ra-
    tionale of the Supreme Court’s right-to-travel cases. I will take
    each feature of the Indiana provision, including its applica-
    tion to relocating persons like the plaintiffs, in turn to explain
    my view.
    44                                                   No. 19-2523
    5.
    Start with the benign application of the other jurisdiction
    provision: If an offender relocates to Indiana from a state that
    did not require him to register, then he will not be made to
    register in Indiana. I agree with the majority that this is one
    aspect of the provision showing that Indiana is not invariably
    discriminating against residents who relocate from other
    states.
    Of course, as the majority recognizes, this was true in
    Saenz as well. For the recipients of public benefits who were
    relocating to California from other states, California capped
    the amount of such benefits such individuals could receive
    during their first year of residence in California at the levels
    they received in their prior states of residence for a period of
    one year. But not every state had public benefit levels that
    were lower than California’s relatively generous payments; a
    handful gave their residents equal or greater benefits. Indi-
    viduals relocating from those states thus suffered no disad-
    vantage as a result of their relocation; they received the same
    benefit amounts upon relocation that a long-standing Califor-
    nian would.

    residents based on their recent arrival in California.

    So the fact that not every sex offender who relocates to In-
    diana from another state or travels from Indiana to another
    state will incur a registration obligation as a result does not
    rule out the possibility that Indiana is interfering with the
    right to travel—indeed, it confirms that what Indiana is doing
    is using another state’s treatment of a sex offender as a proxy
    No. 19-2523                                                     45
    for how he should be treated in Indiana. If an offender is for-
    tunate enough to travel to or relocate from a state that does
    not impose a registration obligation on him, Indiana will not
    do so; but if the other state does require him to register, then
    Indiana will as well. Either way, Indiana is relying on another
    state’s treatment of the offender as dispositive of how he will
    be treated in Indiana.
    6.
    This is unquestionably the case with the six plaintiffs be-
    fore us. All six committed a sex offense in or before 1994,
    when Indiana adopted the original version of its Sex Offense
    Registration Act (SORA). Because the plaintiffs’ crimes were
    committed before they became registrable offenses under In-
    diana law, Wallace precludes the state from imposing a regis-
    tration obligation based on their criminal histories. Wallace
    treats registration as a punishment, and thus one that Indi-
    ana’s ex post facto provision rules out for offenses taking place
    before registration became proscribed for an individual’s of-
    fense. Had the plaintiffs been living in Indiana at the time of
    their offenses and remained there afterward, they would be
    free today of any obligation to register under Wallace.
    For the plaintiffs, it is the fact that they relocated to Indi-
    ana at a later date, and from other states that required them
    to register, that deprives them of the benefit of Indiana’s ex
    post facto provision. Although their crimes were such that, if
    committed in Indiana, they would not be registrable offenses
    under Wallace, because each of the plaintiffs lived previously
    in a jurisdiction that treated the offenses as registrable—and
    saw no ex post facto problem with doing so—Indiana seizes on
    the prior registration obligation itself to demand registration
    46                                                         No. 19-2523
    in Indiana. It is thus one’s relocation from such a state that is
    the trigger for the registration obligation in Indiana.
    Plaintiff Brian Hope’s history makes plain the problem.
    Hope in fact committed his sex offense in Indiana. He com-
    mitted the offense in 1993 and pleaded guilty in 1996. In 2000,
    he completed his probation. In 2004, he moved to California
    and later to Texas, where he was required to register under
    Texas law based on his Indiana conviction. 6 When he re-
    turned to Indiana in 2013 to help care for an ailing family
    member, Indiana invoked the other jurisdiction provision to
    require him to register in Indiana. Given the date of his of-
    fense, Indiana law does not treat his criminal history as one
    requiring registration: Again, Wallace holds that the state’s ex
    post facto provision forbids it. But because Hope previously
    lived in Texas, which did treat his offense as one requiring reg-
    istration, Indiana relies on the prior registration obligation it-
    self to demand that he register in Indiana. But for his travel to
    and from Texas, Hope would have no such obligation as a
    matter of Indiana law. See also Ammons v. State, 
    50 N.E.3d 143
    ,
    144–45 (Ind. 2016) (per curiam) (no ex post facto violation
    where Indiana resident committed sex offense pre-SORA,
    later moved to Iowa, which required him to register based on
    his Indiana conviction, and upon subsequent return to Indi-
    ana was required to register based on the Iowa registration
    obligation).
    The same, of course, is true with respect to the other five
    plaintiffs. Like Hope, they committed sex offenses (albeit not
    Hope himself does not concede that Texas required him to register
    6
    based on his Indiana conviction. For present purposes, I am accepting In-
    diana’s representation that he was required to register on this basis.
    No. 19-2523                                                   47
    in Indiana) that were not registrable in Indiana when the
    crimes took place. So under Wallace, Indiana’s ex post facto pro-
    vision would bar the state from imposing a registration re-
    quirement based on their criminal histories. Instead, the state
    looks to the obligations imposed on the plaintiffs by their for-
    mer states of residence as the trigger for registration in Indi-
    ana.
    As a consequence of this scheme, the plaintiffs arrived in
    Indiana with a lesser set of rights than otherwise similarly-
    situated Indiana offenders. Rather than treat the offender’s
    criminal history as the dispositive factor in deciding whether
    registration is required—and permitted by Indiana’s ex post
    facto provision—Indiana has looked instead to what civil bur-
    dens an offender’s former state of residence imposed on him
    and adopts those burdens as its own.
    In effect, the state is treating an offender who moved to
    Indiana from, say, New York, where he was required to reg-
    ister, as if he remains a citizen of New York for registration
    purposes, and he cannot claim the benefit of Indiana’s ex post
    facto clause in the same way that a lifelong Indiana resident
    with the identical criminal history can. Even Hope, who was
    an Indiana resident when he committed his sex offense, has
    lost the benefit of Indiana’s ex post facto decision because he
    left Indiana and for a time resided in another state which bur-
    dened him with a registration obligation that Wallace fore-
    closed Indiana from imposing. Because he was formerly a cit-
    izen of Texas, Indiana requires Hope to carry the same burden
    as a Hoosier that he carried as a Texan.
    48                                                     No. 19-2523
    7.
    This unique feature of Indiana’s registration scheme—re-
    quiring registration based not on one’s criminal history and
    on how Indiana law treats that history, but rather on how an-
    other state treated that history as a matter of its own law (even
    if it is an Indiana criminal history)—implicates the core con-
    cerns that have animated the Supreme Court’s right-to-travel
    decisions. Indiana is classifying the six plaintiffs based on
    their prior domiciles and assigning them a lesser set of rights
    (no ex post facto protection vis-à-vis registration obligations)
    and a greater set of burdens (the duty to register as a sex of-
    fender, in some cases for life) as compared with similar of-
    fenders who lived in Indiana before its SORA was adopted
    and have remained there since. As more recently arrived res-
    idents of Indiana, the plaintiffs do not enjoy all of the same
    rights and privileges as other Indiana residents. See Saenz,

    ble for public aid).
    To be sure, there are factual differences between the of-
    fender-registration scheme at issue here and the public bene-
    fit schemes the Court has addressed previously. Indiana is not
    imposing a durational residency requirement as California
    did in Saenz: it is not requiring any and all offenders who were
    required to register in their former states to register in Indiana
    for a period of one year after their relocation, for example, af-
    ter which the state will re-evaluate whether they must con-
    tinue to register in Indiana based on their criminal histories.
    Indiana’s scheme is more like a fixed-point residency scheme,
    in the sense that had the plaintiffs all established residency in
    Indiana by 1994 and remained there continuously thereafter,
    they would have no obligation to register; but having instead
    relocated to Indiana at later dates, they do have to shoulder
    the burdens of registration. Cf. Soto-Lopez, 
    476 U.S. 898
    , 
    106 S. Ct. 2317
     (veteran must have resided in state at the time he
    entered military service in order to qualify for veterans’ civil
    service preference); Hooper, 
    472 U.S. 612
    , 
    105 S. Ct. 2862
     (vet-
    eran must have been a state resident by specified date in order
    to qualify for tax exemption). Even that analogy is imperfect
    because, as the majority reminds us, any Indiana resident can
    become subject to a registration obligation by commuting to
    another state that requires him to register there. (More on that
    aspect of Indiana’s scheme in a moment.)
    But what Indiana’s registration scheme has in common
    with Saenz in particular is that Indiana is looking to an indi-
    vidual’s treatment by his former state of residence as the de-
    terminant for how he will be treated by Indiana, and limiting

    his rights as an Indiana citizen based on the rules of his former
    domicile. Had Hope never left Indiana, he would by virtue of
    the Wallace decision be free of any obligation to register today.
    But because he left Indiana and for a time resided in Texas,
    whose own ex post facto clause did not preclude the imposition
    of a registration obligation upon him, he now occupies a dis-
    tinct tier of Indiana citizenship which requires him to register
    for life. In one respect, his case is like that of a veteran who
    did not yet live in New Mexico as of the qualifying eligibility
    date the state established for a special tax break for veterans.
    Hooper. In another, he is like a public aid recipient relocating
    to California, who is assigned a lesser set of benefits upon ar-
    rival from another state, Saenz, except that here the benefit in
    question is not public aid but one’s ability to invoke Indiana’s
    ex post facto protections, and instead of being temporary, the
    lesser benefit is permanent. Cf. Soto-Lopez, 
    476 U.S. at 909

    106 S. Ct. at 2324
     (plurality) (“a permanent deprivation of a sig-
    nificant benefit, based only on the fact of nonresidence at a
    past point in time, clearly operates to penalize appellees for
    exercising their right to migrate”).
    Certainly it is true that the Supreme Court has not ad-
    dressed the right to travel in this particular context. But what
    it has already said about a state’s obligation to treat newcom-
    ers on equal terms with longer-term residents applies with
    equal force here. With respect to the state’s ex post facto guar-
    antee, Indiana is treating each of the plaintiffs as a stranger
    rather than one of its own, relegating them to the more bur-
    densome status they held in their prior domiciles as offenders
    subject to punitive registration requirements. Cf. Mem. Hosp.,
    
    415 U.S. at
    261–62, 94 S. Ct. at 1084 (“Not unlike the admoni-
    tion of the Bible that, ‘Ye shall have one manner of law, as well
    for the stranger, as for your own country,’ Leviticus 24:22
    No. 19-2523                                                     51
    (King James version), the right of interstate travel must be
    seen as insuring new residents the same right to vital govern-
    ment benefits and privileges in the States to which they mi-
    grate as are enjoyed by other residents.”).

    But what of the fact that any citizen of Indiana, however
    long he has resided in the state, can incur a registration obli-
    gation simply by commuting to another state that requires
    him to register so long as he is present there? See, e.g., 730 Ill.
    Comp. Stat. 150/3(a-5) (“An out-of-state student or out-of-
    state employee shall, within 3 days after beginning school or
    employment in this State, register in person and provide ac-
    curate information as required by the Department of State Po-
    lice.”). Certainly this is another point of distinction between
    this case and the Supreme Court’s precedents, and as the ma-
    jority points out, this application of Indiana’s scheme shows
    that residency per se is not always the triggering factor for the
    obligation to register (although it is for the plaintiffs). But
    one’s travel certainly is the trigger, and as in the case of relo-
    cation to Indiana from another state, one’s travel for work or
    study to another state that requires registration while there
    again results in the permanent loss of rights vis-à-vis other
    Indiana citizens. Although the commuter scenario is not pre-
    sented in this case, it implicates the Supreme Court’s right-to-
    travel jurisprudence just as surely as the plaintiffs’ relocation
    scenario does.
    Consider what happens when a lifelong Indiana resident
    who was convicted of a sex offense pre-SORA commutes to
    another state—neighboring Illinois, for example—for work or
    study and must register there as a matter of Illinois law. Now
    he has been required to register in another jurisdiction, and

    Indiana can cite that Illinois registration requirement as the
    basis for requiring him to register in Indiana. As a result of his
    travel, this individual has now effectively lost the benefit of
    Indiana’s ex post facto clause and the Wallace decision. His
    criminal history is precisely the same as it was before. He has
    not violated the terms of supervision or a protective order, or
    taken some other action that suggests he poses an increased
    risk of recidivism or danger to others. Nothing about his back-
    ground has changed except for the fact that he traveled to an-
    other jurisdiction that required him to register as a matter of
    its own law (including its own ex post facto jurisprudence), so
    long as he was present in that other state. Without ever sur-
    rendering his Indiana citizenship, he leaves Indiana with one
    set of rights and obligations and returns with another, simply
    because he traveled to another state with a different set of
    rules.
    From the earliest days of this country, the right to travel
    freely among the states has been recognized as an essential
    right of national citizenship. See Articles of Confederation, art.
    IV, § 1 (1778) (recognizing a right of “free ingress and regress
    to and from any other State” and affording to the free inhab-
    itants of each state “all privileges and immunities of free citi-
    zens in the several states”); U.S. Const., art. IV, § 2, cl. 1 (“[t]he
    citizens of each state shall be entitled to all Privileges and Im-
    munities of Citizens in the several States”); id., amend. XIV,
    § 1 (“All persons born or naturalized in the United States, and
    subject to the jurisdiction thereof, are citizens of the United
    States and of the State wherein they reside. No State shall
    make or enforce any law that shall abridge the privileges or
    immunities of citizens of the United States[.]”); Corfield v.
    Coryell, 6 Fed. Cas. 546, 552 (Cir. Ct. E.D. Pa. 1823) (Bushrod
    Washington, Circuit Justice) (“The right of a citizen of one

    members of the same community, must have the right to pass

    freely as in our own States.”); Edwards,

    hold squarely that it is a privilege of citizenship of the United
    States, protected from state abridgment, to enter any state of
    the Union, either for temporary sojourn or for the establish-
    ment of permanent residence therein and for gaining result-
    ant citizenship thereof. If national citizenship means less than
    this, it means nothing.”); Shapiro, 
    394 U.S. at 629
    , 
    89 S. Ct. at 1329
     (“This Court long ago recognized that the nature of our
    Federal Union and our constitutional precepts of personal lib-
    erty unite to require that all citizens be free to travel through-
    out the length and breadth of our land uninhibited by stat-
    utes, rules, or regulations which unreasonably burden this
    movement.”).
    Traveling from one state to another at the cost of surren-
    dering the rights one otherwise enjoys as the bona fide resi-
    dent of one’s home state is not free travel. Indiana cannot, I
    submit, tell one of its citizens, “You have all the rights of a
    Hoosier today, but if you travel to another state that accords
    54                                                   No. 19-2523
    you lesser rights, you return with only so many rights as that
    state gave you.” To do so may implicate the first as well as the
    third aspect of the right to travel, see ante at 11 (outlining the
    three aspects), but it certainly violates the central teaching of
    the Supreme Court’s right-to-travel precedents, which is that
    a state cannot invidiously classify its residents, and afford
    them differential rights, based on when and whence they
    have come to the state.

    States can and do reach different conclusions about what
    crimes should require registration. They also can and do reach
    different conclusions about whether registration obligations
    are punitive, such that they implicate their own ex post facto
    provisions. What they cannot do, having settled these ques-
    tions in a particular way, is to apply a different set of rules to
    a citizen who has relocated from a jurisdiction that answered
    the questions differently. In terms of his rights as a state citi-
    zen, an Indiana citizen newly relocated from Texas is not a
    former Texan, he is a Hoosier, period, and he must be treated
    as such.
    Indiana decided to require registration for the particular
    offenses that the plaintiffs committed, but only after the plain-
    tiffs committed those crimes. And because Indiana’s Supreme
    Court has decided that the state’s registration obligations are
    punitive, Indiana’s ex post facto provision bars the state from
    requiring registration of all six plaintiffs based on their crimi-
    nal histories. The state cannot pick and choose which of its
    residents can claim the benefit of that provision, but that is in
    effect what Indiana is doing. By placing its reliance on the fact
    that an offender relocated from another state that imposed a
    registration obligation as a matter of its own laws (including
    No. 19-2523                                                    55
    its ex post facto jurisprudence) as the basis for requiring the
    offender to register in Indiana, it is precluding the offender
    from claiming the benefit of the Indiana ex post facto clause
    that another citizen of Indiana would be entitled to claim. It is
    saying to plaintiff Hope, “Yes, you had a right to be free from
    registration when you previously lived in Indiana and com-
    mitted your offense, but you lost that right when you moved
    to Texas, which interpreted its own legal provisions so as to
    require you to register.”
    None of the six plaintiffs in this case has done a single
    thing to distinguish himself from a similarly-situated Indiana
    offender who, by virtue of the timing of his residency in Indi-
    ana, cannot be required to register under Wallace—except re-
    locate (i.e., travel) from another state that had different regis-
    tration rules. The right to travel, as conceived and applied by
    the Supreme Court, forbids such inconsistent and discrimina-
    tory treatment of Indiana’s citizens. The express logic, if not
    the fact-specific holdings, of the Supreme Court’s right-to-
    travel precedents, call upon us to affirm the district court’s
    decision to grant the plaintiffs declaratory and injunctive re-
    lief on this point.
    For the foregoing reasons, and the additional reasons set
    forth in the panel’s now-vacated majority opinion, 
    984 F.3d 532
    , I respectfully dissent as to this aspect of the court’s deci-
    sion.
