Green Card, an Old Conviction, and a Trip Coming Up? The Supreme Court Raised the Stakes. Here Is How to Travel Prepared.

For most green card holders, coming home from a trip abroad is the easy part. You hand the officer your card, you answer a question or two, and you are waved through. A recent Supreme Court decision means that, for a smaller group of permanent residents, that moment now deserves more thought and a little preparation. The good news is that preparation is very much within your control.

On June 23, 2026, the Court decided Blanche v. Lau, No. 25-429. The case involved a lawful permanent resident who had a criminal matter in his past, left the country for a short trip, and was treated as an applicant for admission when he tried to return. The question was how much the government has to prove, and when, before it can treat a returning resident that way. Let us explain what the Court said, who it actually affects, and the concrete steps that keep you in control of your own travel.

The protection most green card holders still have

Start with the reassuring part, because it is true for the large majority of permanent residents. Under the law at 8 U.S.C. section 1101(a)(13)(C), a green card holder returning from a trip is generally not treated as seeking admission at all. You are regarded as someone who already belongs here, and a brief trip does not put your status on the table. If you have no criminal history, this decision does not change your life.

The statute, however, lists specific exceptions. One of them applies to a resident who has committed certain offenses, including a crime involving moral turpitude. For that narrower group, the trip abroad can reopen the question of admission. Blanche v. Lau is about how that exception works in practice.

What the Court actually decided

Here is the heart of it, in plain terms. The government's process for treating a returning resident as an applicant for admission has two steps. At the first step, the government only needs to show that the person committed a qualifying offense in order to treat them as seeking admission. At the second step, a conviction or a formal admission of the crime is what is required to actually find the person inadmissible.

The fight in Lau was about the first step. The lower court had said the government needed clear and convincing evidence that the resident really committed the crime before it could even start treating him as an applicant for admission. The Supreme Court disagreed. It held that the law does not require that higher level of proof at step one. In practical terms, the door to questioning a returning resident with a criminal history now opens more easily than some courts had assumed.

We can be honest that this is not the result we would have wanted. But notice what the decision does not say. It does not say that every green card holder is suddenly at risk. It does not erase the strong protection that returning residents generally enjoy. And it does not take away your ability to prepare, to challenge a wrongful detention, or to fix an underlying problem before you travel.

Who should pay close attention

If you are a permanent resident and you have any arrest or conviction in your history, anywhere, at any time, this decision is a signal to plan ahead before international travel. That is true even if the case felt minor, even if it was dismissed, even if it happened decades ago, and even if you have traveled since without a problem. Immigration law treats criminal history in its own surprising way. Offenses that sound small can count as crimes involving moral turpitude, and offenses that sound serious sometimes do not. You cannot tell from the name of the charge alone.

The competition for your attention here is the voice that says you have traveled before and nothing happened, so why worry now. That voice is comforting and it is exactly the wrong guide after Lau. The landscape shifted. What was safe last year deserves a second look this year.

How to travel prepared, not afraid

This is the part you control, so let us be specific. Before you book any international trip, have an immigration lawyer review your complete criminal history, including the actual court records, not just your memory of what happened. The precise statute you were charged under, and the final disposition, decide everything. A good review can often tell you that your offense does not trigger the exception at all, which means you can travel with real peace of mind.

If your offense might qualify, there are often moves to make first. Sometimes the right step is post-conviction relief that changes or vacates the old conviction. Sometimes it is applying for a waiver before you go. Sometimes it is gathering documentation and a legal memo to carry with you, so that if you are questioned, your lawyer's analysis is in your hand and not just in your head. And if you are ever held at the airport, say clearly that you want to speak to a lawyer, do not sign anything giving up your green card, and remember that being treated as an applicant for admission is the start of a process, not the end of your status.

Let us look before you leave

The theme of Blanche v. Lau is not that the door slammed shut. It is that the margin for error got thinner for a specific group of people, and that planning ahead matters more than it used to. That is a problem we know how to solve. For twenty years we have helped permanent residents understand exactly where they stand before they travel, and we have stood beside the ones who got stopped anyway.

If you have a green card and any criminal history, do not let a vacation turn into a fight to come home. Let us review your record while there is time to act on what we find.
