Last week’s US Supreme Court decision in Mullin v. Doe has cleared the way for the Trump administration to revoke Temporary Protected Status (TPS) for hundreds of thousands of Haitian and Syrian nationals, removing a key judicial barrier that had delayed termination. The ruling, which held that lower federal courts lack authority to block the Department of Homeland Security from ending designations, arrives as Homeland Security Secretary Mark Mullin warns beneficiaries they must “seek permanent residence or leave the country,” and offers assistance with repatriation.

Viewed from Washington, the administration frames the decision as a restoration of executive authority over a programme whose “temporary” nature was stretched by successive renewals. Mullin told CNN’s “State of the Union” that TPS is “not permanent status,” and his department has already moved to revoke protections for nationals of 13 of the 17 countries currently covered, including Afghanistan, Venezuela and Nepal. The Supreme Court’s majority implicitly validated the administration’s argument that the designation is a discretionary, time‑limited measure, not a right conferring indefinite residency.

From Ohio, a Republican governor has broken ranks. Mike DeWine, whose state hosts a significant Haitian workforce, argued that returning migrants to Haiti would be unsafe and economically damaging, noting many work in healthcare. In New York, Mayor Zohran Mamdani declared the ruling “not something we will ever accept,” raising the spectre of non‑compliance that Democratic Senator John Fetterman called a “constitutional crisis.” The American Immigration Lawyers Association described the judgment as “a catastrophic loss,” and civil‑society organisations warn that affected families—in some cases residing in the US for over a decade—will now face swift uncertainty over work permits and protection from deportation.

The ruling’s effects extend beyond Haitian and Syrian communities: it weakens the ability of immigrants to challenge TPS terminations in court, and analysts in London note it may accelerate the administration’s effort to wind down what critics brand “permanent temporary” status. In parallel, the Supreme Court also curtailed asylum access for migrants turned away at the border, reinforcing a broader immigration crackdown. The domestic political fallout is still unfolding, with some congressional Republicans expressing unease over the local economic impact. For now, no national timetable exists for the mass expiry of protections, but Mullin’s statement—combined with the ruling—has shifted the onus onto TPS holders to find an alternative path or face the prospect of departure.
