Since 15 September, international students in the United States no longer stay for the "duration of status". They are admitted until a fixed date, capped at four years, and must apply to US Citizenship and Immigration Services to stay longer. The Department of Homeland Security says this will reduce overstays and fraud.

For undergraduates on a four-year degree, little changes. For doctoral students, it changes a great deal.

Doctorates do not fit in four years

Most American PhD programmes take longer than four years. Under the new rule, almost every international doctoral student will need at least one extension, often in the middle of research, teaching or a job search. Each extension depends on USCIS processing times. A delayed decision can leave a student unsure whether they can travel to a conference, accept a teaching contract or finish a thesis on time.

These are not marginal students. International doctoral candidates make up a large share of the researchers in American laboratories, especially in science and engineering. Many stay after graduating and build companies and careers in the country.

Competitors are watching

Other destinations are tightening their rules too: Australia manages numbers through a planning level, Canada through permit caps, England through a levy. But each of those systems still lets a doctoral student plan a full degree. A student weighing offers will notice which country makes them reapply partway through.

A simple fix

DHS could keep fixed admission periods for most students while admitting doctoral students for the full expected length of their programme, as stated by their university. Extensions would then be the exception, not the rule. Oversight would be preserved, and the country would stop discouraging exactly the people it spends years and research budgets training.
