The Supreme Court’s conservative majority handed the Trump administration a major immigration victory Tuesday, ruling that federal border officials have broader authority to treat some lawful permanent residents as applicants for admission when they return to the United States after travel abroad.
In a 6-3 decision, the Court sided with the administration in a case involving Muk Choi Lau, a lawful permanent resident who was placed on immigration parole after returning from a short trip to China in 2012 because he had been accused of a counterfeiting crime. Lau argued that the immigration officer overstepped by placing him on parole before the government established that he had committed a crime that could trigger immigration consequences. The Court rejected that argument.
“Border officers did not have the burden to establish by clear and convincing evidence that Lau had committed a crime involving moral turpitude,” Justice Clarence Thomas wrote for the majority.
The decision gives immigration officials more flexibility to classify some returning green card holders as if they are seeking admission into the country, rather than returning to a country where they already hold permanent legal status. That distinction can carry serious consequences. A lawful permanent resident treated as an applicant for admission may face detention, parole restrictions, or removal proceedings before guilt has been proven in criminal court.
The ruling was backed by Chief Justice John Roberts and Justices Clarence Thomas, Samuel Alito, Neil Gorsuch, Brett Kavanaugh, and Amy Coney Barrett. Justice Ketanji Brown Jackson dissented, joined by Justices Sonia Sotomayor and Elena Kagan.
The case began years before Trump returned to office, but the administration embraced it as part of a broader argument for expansive executive power over immigration. Federal attorneys argued that suspicion of a crime was enough to put a lawful permanent resident on immigration parole. The Court’s conservative majority agreed with the government’s broader reading of border authority.
For immigrant rights advocates, the ruling threatens to weaken one of the central promises of permanent residence: that a green card holder has a stable legal home in the United States. Lawful permanent residents are not tourists or temporary visa holders. Many have lived in the country for years or decades, raising families, working, paying taxes, buying homes, and building communities. The dissent warned that the majority’s decision places that security at risk.
Jackson wrote that lawful permanent residents “are as close to citizenship as one can get absent naturalization,” and said they are allowed to “travel in and out of the United States” with more ease than other non-citizens. In her view, the ruling undermines “the benefits and security that come with having a green card” by letting the government first treat permanent residents as “seeking admission” and justify the decision later.
That sequence, the dissent argued, matters. Under the Court’s ruling, immigration officials may act first, placing a green card holder into a precarious immigration status based on an accusation, while the person later fights to prove that the government lacked the basis to do so. Jackson warned that this could leave permanent residents trapped for years in legal uncertainty or detention.
“I worry that the Court has now handed the Government a massive blank check,” Jackson wrote.
The facts of Lau’s case illustrate the stakes. Lau was returning from a short trip to China when he was placed on immigration parole because he had been accused of counterfeiting. He later pleaded guilty to selling counterfeit clothes in New Jersey, and the Department of Homeland Security moved swiftly toward deportation proceedings. Lau challenged the initial parole decision, arguing that the government could not treat him that way without first meeting a higher evidentiary standard. The Supreme Court disagreed.
The decision does not mean every green card holder can be denied reentry or automatically deported. But it does make it easier for the government to use accusations of certain crimes to place returning lawful permanent residents into a more vulnerable category. For permanent residents with pending charges, unresolved allegations, or prior criminal issues, the ruling could make international travel far riskier.
The case also fits into a larger immigration agenda now before the Supreme Court. The justices are considering Trump’s push to end birthright citizenship, an attempt to revive a restrictive asylum policy, and efforts to terminate temporary legal protections for migrants fleeing war and natural disasters. Together, the cases could reshape the legal architecture of immigration and citizenship in the United States.
The birthright citizenship case carries especially sweeping implications. The United States has recognized birthright citizenship since ratification of the 14th Amendment in 1868. Trump’s effort seeks to narrow who is recognized as a citizen at birth, a move that would mark a major break from more than a century and a half of constitutional practice.
Tuesday’s green card ruling also came the same day the Supreme Court narrowed the ability of non-U.S. citizens to bring lawsuits over human rights violations committed abroad. In that case, the Court ruled that members of the Falun Gong religious movement could not sue Cisco Systems, a U.S. technology company, over allegations that the company helped facilitate detention and torture by the Chinese state.
Sotomayor criticized that decision, saying it throws out “two decades of settled precedent” and closes the Court’s doors “to virtually every future litigant seeking redress for a violation of international law” under the Alien Tort Statute. That law, passed in 1789, has long provided a path for non-U.S. citizens to bring certain international law claims in U.S. courts.
Taken together, the two rulings signal a Court increasingly willing to narrow legal protections and courtroom access for non-citizens, while expanding government authority in immigration enforcement. For the Trump administration, the Lau decision adds another tool to an already aggressive immigration crackdown. For lawful permanent residents, it raises a more basic question: how secure is permanent status if an accusation at the border can begin the process of detention and removal?
The decision is likely to shape how immigration attorneys advise green card holders with any pending or past criminal allegations. Some may be warned to avoid international travel. Others may face more scrutiny at airports and ports of entry. Families could be left navigating sudden detention or deportation proceedings after a routine trip abroad.
The ruling also intensifies concerns about due process in immigration law, where civil proceedings can carry life-altering consequences. Deportation can separate families, end employment, destabilize housing, and exile people from the communities they have long called home. When those consequences begin before guilt is proven, the dissent argued, the protections attached to permanent residence become far weaker.
For the Court’s majority, the decision rests on border authority and the statutory power of immigration officials. For the dissent, it represents a dangerous erosion of Congress’s protections for green card holders and a major shift in the relationship between permanent residents and the government.
