Trump administration hits double legal blow over immigration agenda

On September 15, 2026, the Trump administration found itself wrestling with two separate legal setbacks that could reshape its immigration blueprint. First, a Boston federal judge put the brakes on a Department of Homeland Security (DHS) regulation that would have imposed strict time limits on several non‑immigrant visas.

U.S. District Judge F. Dennis Saylor IV, appointed by George W. Bush, granted an injunction at the request of a coalition of trade unions and higher‑education advocacy groups. The proposed rule would have capped F‑student visas at four years, limited J‑exchange visas to the same period, and slashed the maximum stay for I‑visas—used by foreign journalists—to just 240 days. Saylor called the administration’s security rationale “exceptionally weak,” warning that the move could cripple research labs, tech startups, and the broader economy that relies on the contributions of roughly 1.6 million international students and half a million exchange visitors.

“We have built a nation on the ideas of scholars and the stories of reporters from abroad,” the judge noted, adding that the damage to higher education and innovation would be “catastrophic.” The injunction halted the rule just hours before it was slated to take effect on Tuesday.

While the visa caps were frozen, a separate legal battle erupted in Manhattan. A coalition of 22 Democratic‑led states and the District of Columbia, led by New York, California and Illinois, filed a suit to block a new DHS regulation set to launch on Friday. The regulation broadens the definition of “public charge,” allowing immigration officers to deny green‑cards to applicants who have ever used non‑cash public benefits—such as food stamps or Medicaid—for themselves or their families.

Under the prior Biden administration, cash assistance could factor into the public‑charge test, but non‑cash aid was off‑limits. Trump’s rule seeks to roll back that protection, reviving an earlier policy that many critics say punishes immigrants for seeking help they’re legally entitled to.

A DHS spokesperson dismissed the plaintiffs as “left‑wing leaders” scared of losing federal funds, suggesting that hundreds of thousands of undocumented people might quit welfare programs if the rule stands. New York City Mayor Zohran Mamdani retorted that the policy “pushes immigrant families away from the programs that have kept people fed and healthy for decades.”

The lawsuits argue that the administration overstepped its authority by bypassing Congress, which alone can set the criteria for permanent residency. By penalising lawful use of public benefits, the plaintiffs contend the rule conflicts with existing federal statutes.

Both legal challenges underscore the growing friction between the Trump administration’s immigration agenda and a broad coalition of states, cities, and advocacy groups. With the visa caps on hold and the public‑charge rule under fire, the administration’s next steps remain uncertain.
