WASHINGTON — The Supreme Court on Thursday handed the Trump administration two of its most sweeping immigration victories yet — eliminating meaningful court oversight of Temporary Protected Status terminations and allowing border officials to physically block asylum seekers from ever setting foot on U.S. soil.
The decisions, both written by Justice Samuel Alito and decided 6–3 along ideological lines, reshape the legal architecture of humanitarian protection in America. Taken together, they leave an estimated 356,000 Haitians and Syrians facing imminent loss of their legal status — and open the door to stripping TPS from up to one million people more.
What the Court Did — and What It Means
In Mullin v. Doe and Trump v. Miot, the Court ruled that a 1990 statutory review bar blocks virtually all non-constitutional court challenges to TPS terminations. Haitian TPS holders had argued the termination was driven by racial animus — pointing to statements by President Trump and DHS Secretary Kristi Noem about Haitians and other non-white migrants. The Court, applying the Arlington Heights framework, concluded the plaintiffs were unlikely to prevail, citing the administration’s across-the-board policy of ending TPS designations as a facially race-neutral rationale.
Justice Kagan, writing in dissent joined by Justices Sotomayor and Jackson, warned that under the majority’s logic, TPS communities that have lived legally in the United States for decades can have their status revoked through flawed or pretextual processes with no meaningful judicial check.
In the metering case, Mullin v. Al Otro Lado, the Court held that asylum seekers physically standing in Mexico at a port of entry have not “arrived in the United States” under the Immigration and Nationality Act — and therefore have no statutory right to request asylum. Border officials may now indefinitely prevent migrants from stepping onto U.S. soil, eliminating the legal trigger for asylum processing altogether.
Justice Sotomayor read her dissent aloud from the bench — a signal reserved for decisions the dissenters consider most consequential. She invoked the St. Louis, the ship carrying Jewish refugees turned away before World War II, and accused the majority of allowing agents to evade Congress’s intent by the simple act of physically blocking a human being from crossing a line.
The Numbers Behind the Ruling
Roughly 350,000 Haitians hold TPS, many of them in the United States for more than a decade following the catastrophic 2010 earthquake. Approximately 6,000 Syrians received TPS amid civil war and the Assad regime’s repression. Both groups had seen their designations repeatedly extended — until the Trump administration, under Executive Order 14159, moved to terminate them in 2025 as part of a sweeping crackdown on humanitarian programs.
Advocates warn the logic extends far beyond Haiti and Syria. Venezuela, Nicaragua, Honduras, El Salvador, Somalia, and Ethiopia all have long-standing TPS populations. The total exposure: roughly one million people.
The Border Door Closes
The metering ruling revives and expands a policy first formalized under Trump, briefly used under Obama, and rescinded by Biden in 2021. Under the ruling, Customs and Border Protection officers can station themselves at ports of entry — on bridges, in inspection lanes — and simply refuse entry. No step on U.S. soil, no asylum claim. No asylum claim, no protection.
In practice, that means asylum seekers wait in Mexican border cities — Juárez, Tijuana, Matamoros — in encampments long documented for kidnapping, extortion, and cartel violence. The wait is now potentially indefinite. The protection, legally, now nonexistent.
Advocacy groups including the American Immigration Council condemned the ruling as delivering a direct blow to rights Congress wrote into the INA. Lawyers are already signaling they will pivot to non-refoulement arguments, conditions in Mexican camps, and international law — threads the majority left unaddressed.
What Comes Next
DHS can now move ahead with TPS termination notices already published in the Federal Register for both Syria and Haiti. For the southern border, expect Trump’s DHS to formally reinstate and scale physical turnback operations at ports of entry — and watch for guidance from CBP field leadership in the coming days.
On Capitol Hill, advocates are pressing for a congressional fix that would clarify the asylum statute to include people seeking inspection at ports of entry. That fight starts Thursday — and it starts losing.
Justice Sotomayor’s bench statement closed with a question the majority never answered: what happens to the people turned back? The Court, having redrawn the line, offered nothing on what waits on the other side of it.
The Court ruled. The clock is running. Migrant Insider will be in the halls of Congress this week asking the questions these opinions leave unanswered — because someone has to. Paid subscribers are what make that possible. If this story matters to you, make sure we can keep reporting it.
