Supreme Court's Blanche v. Lau Ruling Impact

When a Green Card Isn't Enough: Blanche v. Lau's Border Trap

The Supreme Court's 6–3 Blanche v. Lau ruling lets border officers treat lawful permanent residents with pending or past criminal issues as new applicants — with no clear-and-convincing evidence needed.

Border officers no longer need "clear and convincing" evidence that a returning lawful permanent resident has committed a crime involving moral turpitude before treating that resident as an "applicant for admission." That is the holding of Blanche v. Lau, the Supreme Court's 6–3 ruling issued June 23, 2026. The decision converts what had, for a year, been an aggressive Trump-era enforcement posture toward returning green-card holders with old or unproven criminal records into settled statutory law — shifting the moment at which the government must prove its case from the port of entry to a later removal hearing, and stripping away the procedural cushion that had shielded long-resident immigrants from being detained on suspicion alone.

What the Court actually held

The petitioner, Muk Choi Lau, has been a lawful permanent resident since 2007. New Jersey charged him with third-degree trademark counterfeiting on May 7, 2012; while the charge was pending, he flew to China and returned through John F. Kennedy International Airport on June 15, 2012. A border officer refused to treat him as admitted, paroled him into the country under INA §212(d)(5), and — after his 2013 guilty plea — the government charged him as an inadmissible applicant for admission. Those facts come from the Supreme Court's syllabus, which the Legal Information Institute has posted in full.

The Second Circuit vacated Lau's removal order in March 2025, ruling in Muk Choi Lau v. Bondi, 130 F.4th 42 that "a pending criminal charge does not provide the clear and convincing evidence of a CIMT necessary for DHS to consider an LPR an applicant for admission at the time of reentry." Because that decision conflicted with the Fifth and Ninth Circuits, the Supreme Court granted certiorari on January 9, 2026, and heard oral argument on April 22.

Writing for a six-justice majority, Justice Clarence Thomas held that INA §1101(a)(13)(C)(v) "incorporates by reference" the offenses listed in §1182(a)(2) — "not its requirement of conviction." A lawful permanent resident who "has committed" a crime involving moral turpitude "can be regarded as seeking an admission" the moment he crosses the border, even if the conviction comes later. The government's burden, the Court reasoned, arises in removal proceedings before an immigration judge — not at the inspection booth.

Justice Ketanji Brown Jackson, joined by Justices Sonia Sotomayor and Elena Kagan, dissented sharply. "I worry that the Court has now handed the Government a massive blank check," Jackson wrote in dissent, warning that the majority leaves green-card holders in "immigration limbo" before they have been convicted of anything.

The procedural switch that changes everything

The stakes turn on a technical but decisive shift in the burden of proof.

Under long-standing Board of Immigration Appeals precedent — Matter of Rivens, 25 I. & N. Dec. 623 (BIA 2011) — the government must prove by clear and convincing evidence that a returning LPR falls within one of the six statutory exceptions to admitted status. The dispute in Blanche v. Lau was when that burden bites. In its merits response brief, Lau's counsel argued that the government must have the evidence "at the time the LPR reenters the country" — otherwise DHS lacks the authority to parole rather than admit.

Thomas's majority disposes of that sequence. Border officers may now parole an LPR on the basis of an arrest, a pending indictment, or an incident report — evidence that would not survive a criminal trial — and let a subsequent conviction retroactively validate the classification. The consequence, per the Supreme Court syllabus: once paroled rather than admitted, an LPR "can be turned away, detained, or conditionally let back into the country" — and the parole "often goes hand in hand with confiscation of the LPR's physical green card."

An amicus brief from the Asian American Legal Defense and Education Fund put the practical arithmetic plainly: under the government's "parole-and-see" approach, an officer could rely on "arrest records, incident reports, or their subjective suspicion alone" — a "dangerously low bar with no defined stopping point."

Why this ruling landed on top of an enforcement wave

Blanche v. Lau did not create a new border regime. It legalized one already in operation.

Beginning in February 2025, U.S. Customs and Border Protection began sweeping up returning green-card holders whose criminal records had, for years, been treated as immigration-irrelevant. NPR reported the case of Lewelyn Dixon, a 64-year-old Filipina LPR of 50 years, detained at Sea-Tac Airport over a 2001 embezzlement conviction of roughly $6,500 and held in ICE custody for nearly three months. Fabian Schmidt, a German-born electrical engineer, was detained at Boston Logan over a decade-old California marijuana misdemeanor that had been dismissed. Immigration attorney Benjamin Osorio told NPR he had not seen such cases in 12 years of practice before February 2025, and had picked up three more in months — an anecdotal signal that CBP's discretion at the border had shifted before any court blessed it.

CBP framed the shift as routine. "The Trump administration is enforcing immigration laws, something the previous administration failed to do," the agency told NPR. Reporter Martin Kaste noted that only "a fraction of 1% of the 13 million green card holders" had been refused reentry this way — a small share, but one that now sits atop a statute the Court has read to permit far more.

The Vartelas baseline the majority overrode matters here. In Vartelas v. Holder, 566 U.S. 257 (2012), the Court had suggested in a footnote that treatment as an applicant for admission required a conviction. Thomas's opinion dismisses that reading as "dictum," clearing the doctrinal underbrush.

Who wins, who loses

The winners are unambiguous. DHS gains latitude it had lost in the Second Circuit and hoped to keep in the Fifth and Ninth. Border officers can now act on suspicion without documenting the record that would once have been required to justify paroling a resident. The Trump administration, which argued in its briefs that suspicion of a crime is sufficient to reclassify an LPR at the border, now has the Court's imprimatur for that theory of §1101(a)(13)(C)(v).

The losers are more specific than "green-card holders" writ large. They are:

• LPRs with pending state charges — even non-violent, non-final ones — who travel abroad.
• LPRs with old convictions for offenses that could plausibly be classed as crimes involving moral turpitude: theft, fraud, embezzlement, some drug offenses. The State Department's FY2024 Visa Office statistics show 1,861 CIMT ineligibilities issued to visa applicants before waivers — a metric of how routinely the ground is invoked.
• LPRs with arrest records but no conviction: precisely the fact pattern the Second Circuit thought insufficient, and the Supreme Court has now said is not necessarily disqualifying for border action.

There is also a structural loser: the naturalization pipeline. U.S. Citizenship and Immigration Services data released in April 2026 shows citizenship approvals dropped from more than 70,000 in October 2025 to fewer than 33,000 by January 2026, with total processing plummeting from 78,379 completions in September 2025 to 37,832 four months later, NPR reported. The obvious hedge against Blanche v. Lau — file for naturalization — is now moving through a slower and more selective agency.

What the ruling does not do

Three limits deserve emphasis, because immigration lawyers are already fielding panicked calls that overstate the decision.

First, the majority explicitly did not decide whether Lau's trademark-counterfeiting offense was itself a crime involving moral turpitude. It vacated the Second Circuit and remanded for further proceedings on that question, per the syllabus.

Second, the government still concedes that in removal proceedings before an immigration judge, it must prove the CIMT by clear and convincing evidence. The petitioner's brief states this expressly: "At most, the INA requires the government to establish the LPR's commission of that offense by clear and convincing evidence in removal proceedings before an immigration judge."

Third, only immigration judges can revoke lawful permanent resident status. What Blanche v. Lau changes is not the endgame — it changes who bears the risk of delay, detention, and confiscation of the green card in the interim. That interim is the point.

The Bottom Line

The bottom line: Blanche v. Lau is a burden-shifting decision dressed as statutory interpretation, and its real effect is to move the moment of adjudication for LPRs with criminal issues from the port of entry to the detention facility. For the roughly 13 million U.S. green-card holders, the practical rule is now this: if you have a pending charge, a decades-old plea, or an arrest that never went anywhere, the safest citizenship strategy is to file for naturalization before you board a plane — and, if you can help it, not to leave at all until you do.

What to watch

• Lau's remand. The Second Circuit must now decide whether third-degree trademark counterfeiting under New Jersey law is a "crime involving moral turpitude." A ruling either way will guide how narrowly or broadly the CIMT category is drawn in a post-Blanche world.
• DHS/CBP field guidance. CBP has issued no public post-decision parole standards as of July 9, 2026; an updated directive or ICE memorandum would be the first concrete signal of how broadly the agency intends to use its new authority.
• Naturalization backlog. USCIS approval numbers for the second quarter of 2026 will show whether the drop that hit 32,862 approvals in January 2026 has continued — the single most important metric for whether the naturalization hedge is available to the LPRs who need it most.
