Blanche v. Lau: Supreme Court eases evidence step in green-card re-entry

On June 23, 2026, the U.S. Supreme Court ruled in Blanche v. Lau that immigration officers do not have to prove—using a “clear and convincing evidence” standard—that a lawful permanent resident committed a qualifying crime before treating them as “seeking admission” after travel. The decision reshapes how early-stage border decisions can be challenged and how courts may review the step that comes before removal proceedings.

This is informational context, not legal advice.

Background: why some green-card holders can be treated like “applicants” at the border i

Lawful permanent residents (LPRs) are generally treated as already admitted when they return from short trips abroad. But federal immigration law includes an exception: when an LPR has “committed” certain offenses identified in the law, officials may treat the person as “seeking admission,” meaning they are processed under the framework used for people trying to enter rather than people already admitted.

The Supreme Court’s ruling: no “clear and convincing” border-proof step i

The case involved Muk Choi Lau, an LPR who left the United States while criminal charges were pending, then attempted to reenter. A border officer did not treat him as already admitted and instead allowed entry under parole while the criminal matter was resolved. After Lau later pleaded guilty, the government pursued removal based on inadmissibility.

The Second Circuit had required border officers to have “clear and convincing” evidence about the underlying crime before treating a returning LPR as “seeking admission.” The Supreme Court vacated that approach.

In plain terms, the Court said the Immigration and Nationality Act does not add that heightened evidence-burden at the border step. The Court also emphasized that—under the statutory exception—officials may treat an LPR as “seeking admission” based on the commission of a covered offense, and the statute incorporates the relevant crime categories without requiring that the later conviction be what triggers the “seeking admission” label.

What this changes in practice during re-entry screening i

Sequencing at the border: After Blanche v. Lau, the government is not required to meet a “clear and convincing” standard at the specific moment officials decide whether the “seeking admission” exception applies. That can affect the way officers document the decision to parole or otherwise condition entry when a qualifying-crime issue is at stake.

Still fact-dependent: The decision does not erase disputes over what actually happened. It also does not mean every case ends the same way—because later proceedings can still address whether the charged or alleged offense fits the law’s definition and whether the government can prove the necessary elements in the removal framework.

Case posture matters: The Supreme Court did not decide whether Lau’s particular crime was one involving “moral turpitude,” and it sent the case back for further proceedings.

How federal court litigation may shift next i

Because the Supreme Court rejected the “clear and convincing evidence” border-proof requirement, future arguments may focus more on (1) what officials used as the basis for treating a returning LPR as “seeking admission,” and (2) how courts evaluate the government’s evidentiary showing at later stages of the case.

Lower courts may also revisit which stage—border versus removal proceedings—should carry heightened evidentiary burdens when plaintiffs challenge whether the “seeking admission” exception was properly triggered.

Who could be affected, and what remains uncertain i

The decision primarily affects LPR re-entry situations where officials treat a person as “seeking admission” under the “committed” offense exception. That can include cases involving pending allegations or resolved criminal matters that the government says fall within the statute’s qualifying-crime categories.

What’s still uncertain: how DHS/CBP will operationalize documentation of border determinations across different fact patterns, and whether additional disputes arise over how Blanche applies to contested “qualification” issues (including whether the underlying conduct matches the statute’s categories).

What to watch next i

• Further lower-court rulings applying Blanche v. Lau to decide what evidence standards apply at the “seeking admission” step.
• Whether future cases turn on contested facts about the alleged offense, and how courts handle sequencing challenges when the government proceeds on inadmissibility grounds.
• Remand developments in Blanche itself, including the remaining question about whether the covered legal definition was satisfied on the specific record.
