A Four-Year Clock, a Courtroom Defeat, and the Shrinking Welcome for Student Immigrants

For nearly fifty years, the United States told foreign students something simple: stay as long as your studies take. This month, that promise ended twice over — once by regulation, and once by court order.

On July 16, 2026, the Department of Homeland Security finalized a rule scrapping "duration of status," the policy in place since 1978 that let international students remain in the country until they finished their programs. Under the new rule, F and J visa holders are admitted for the length of their program up to a maximum of four years, and must apply for extensions beyond that. The rule also restricts students from changing majors or transferring institutions once they arrive, and takes effect 60 days after publication in the Federal Register.

The government’s case rests on oversight. Homeland Security Secretary Markwayne Mullin said the change lets the country reclaim "its ability to properly screen, vet, and monitor individuals within our borders." DHS pointed to more than 2,100 students who first entered between 2000 and 2010 and still held active F visas as of April 2025 — the "forever students" the agency says exploit an open-ended system.

The scale of that problem invites scrutiny. Over 1.6 million people entered on F visas in 2024 alone, which makes 2,100 a rounding error. The four-year clock also sits awkwardly against how long degrees actually take: bachelor’s degrees average roughly 4.3 years and doctorates 5.7. NAFSA, the leading association of international educators, called the rule "a solution in search of a problem," and a coalition of more than 60 higher education groups warned the limit would simply not work for most students. A doctoral candidate could be asked to leave in the middle of a dissertation.

Nine days later, the pressure arrived from a different direction. On July 24, a federal judge in the Southern District of Illinois ruled that the state’s in-state tuition policy, its RISE Act, and its DREAM Act are unconstitutional as applied to undocumented students, granting the Justice Department summary judgment. The order is paused for 14 days so Illinois can appeal.

The legal logic is narrow. Federal law bars states from granting residence-based college benefits to undocumented immigrants unless the same benefit is offered to every U.S. citizen, wherever they live. The U.S. Attorney said the decision "enforces the statute Congress wrote." Illinois has maintained that "all Illinoisans deserve a fair shot to obtain an education." The students affected generally graduated from an Illinois high school, attended school in the state for at least three years, and pledged to seek permanent residency when eligible. Similar rulings have already landed in Texas, Kentucky, Oklahoma and Nebraska, with cases pending in roughly a dozen states.

Both decisions are legally defensible, and both rest on a real principle: immigration law is written by Congress, not by universities or state legislatures. But they share an assumption worth questioning — that tighter rules cost nothing. Students choose countries years in advance, and uncertainty is its own kind of deterrent.

The honest answer is that a country can enforce its own statutes and still lose something in the process. The right response is not to treat every restriction as a victory, but to keep asking what the enforcement is actually buying.
