A US federal judge on Monday, 15 September 2025, temporarily blocked the Trump administration's proposed four-year cap on international student visas, halting a rule that would have upended academic pathways for hundreds of thousands of foreign students and researchers — including thousands from India. The ruling came just one day before the Department of Homeland Security (DHS) regulation was set to take effect.

The Court's Ruling

Judge F. Dennis Saylor IV of the US District Court in Boston issued a nationwide preliminary injunction, preserving the longstanding 'duration of status' system under which international students may remain in the United States for as long as they are enrolled in an authorised academic programme. Under the blocked regulation, students requiring more than four years — including virtually all doctoral candidates — would have had to seek formal extensions from immigration authorities.

Judge Saylor described the government's justification for the rule as 'exceptionally weak', writing that the existing system had contributed to 'groundbreaking research in science, medicine, and technology, substantial economic growth.' He warned that if implemented, the restrictions could cause damage to the economy and higher-education institutions that 'is likely to be catastrophic.'

What the Blocked Rule Would Have Done

Beyond the four-year cap, the regulation would have restricted students' ability to change programmes, transfer universities, or pursue another degree at the same level without prior government approval. Visiting scholars and foreign journalists would also have been affected. The rule drew particular concern for doctoral students: data from the National Science Foundation cited in court proceedings showed that doctoral programmes take a median of 5.7 years to complete — well beyond the proposed cap.

Judge Saylor also raised concerns about the concentration of power the rule would have granted to immigration officials over academic decisions, warning it was 'not difficult to imagine how that system might be abused to punish those whose viewpoints or research are disfavored by the officials making the decision — or, indeed, punish disfavored institutions.'

Who Challenged the Rule

The legal challenge was brought by a coalition of higher-education organisations and labour unions, including the Presidents' Alliance on Higher Education and Immigration, NAFSA: Association of International Educators, and the Association of Independent Colleges and Universities in Massachusetts. The plaintiffs argued that the four-year deadline was arbitrary and would severely damage universities' ability to attract international talent and conduct advanced research.

Nearly 22,000 public comments were submitted during the rule-making process, with the majority expressing opposition. The DHS had defended its policy after the lawsuit was filed, with a department spokesperson saying: 'Where was the outrage when foreign nationals were abusing the system, violating the terms of their student visas, and making a mockery of our immigration laws?' The government maintained the existing system was outdated and needed to be reformed to 'safeguard national security' — a characterisation Judge Saylor dismissed, writing that the claim 'borders on the absurd.'

Impact on Indian and International Students

India is among the largest sources of international students in the United States, with a significant concentration in doctoral programmes in STEM fields — precisely the cohort most exposed to the proposed cap. The broader chilling effect on enrolment had already begun to manifest: according to figures cited by NAFSA, international applications through the Common Application fell 10% during the latest admissions cycle, while doctoral applications declined 21%.

The preliminary injunction does not permanently invalidate the regulation. It preserves the existing system while the court considers the full merits of the case. The Trump administration may appeal the ruling, and the next court hearing is scheduled for 2 October 2025.
