The Supreme Court handed the Trump administration a pair of significant victories on immigration this week, ruling that asylum seekers at the U.S.-Mexico border do not acquire legal presence in the United States until they physically enter the country, and separately upholding the administration's authority to terminate Temporary Protected Status (TPS) for nationals of Haiti and Syria.

In the asylum case, the Court held that migrants waiting in Mexico under the administration's border enforcement policies cannot claim legal protections that apply only to those who have entered U.S. territory. The ruling clears a major legal obstacle for the administration's efforts to restrict asylum processing at the southern border and is expected to affect tens of thousands of people currently awaiting hearings under various border enforcement programs.

In the TPS case, often referred to by the plaintiff names Mullin v. Doe and related to Miot, the Court ruled that the administration had the authority to revoke TPS designations for Haitian and Syrian nationals. TPS is a humanitarian status granted to people from countries experiencing ongoing armed conflict, environmental disasters, or other extraordinary conditions, shielding them from deportation and allowing them to work legally. The decisions affect an estimated several hundred thousand individuals currently living and working in the United States under those protections.

Legal advocates warned the rulings would expose large numbers of long-term U.S. residents to deportation and create significant uncertainty for immigrant communities. The Biden administration had extended TPS for both Haiti and Syria, but the Trump administration moved to end those designations after taking office in January 2025.

The decisions were among the most consequential immigration rulings in years and are expected to reshape asylum policy and humanitarian protections for the foreseeable future. Immigration attorneys and advocacy groups said they would assess options for further legal challenges, though the Court's definitive rulings leave limited avenues for appeal on the central questions decided.
