A US federal judge has blocked a Trump administration rule that would have changed how long many foreign students could remain in the United States under their student visas. The ruling, issued on September 14, 2026, temporarily prevents the administration from implementing the proposed change while the legal challenge continues. The rule would have replaced the long-standing “duration of status” system with fixed periods of admission. Under the proposed system, F student visas and J exchange visitor visas would generally have been limited to four years, meaning some students and exchange visitors would have needed to apply for extensions if their programmes lasted longer. The rule was scheduled to take effect on September 15. US District Judge F. Dennis Saylor in Boston blocked the policy, according to Reuters, finding that the Department of Homeland Security had not provided sufficient justification for the change. The ruling means the existing system remains in place for now while the legal dispute continues. The case is significant for international students because the proposed policy could have affected students whose academic programmes extend beyond four years or whose circumstances require additional time. Universities and international education organisations have closely followed the dispute because changes to student visa rules can affect admissions, academic planning and international recruitment. However, students should be careful not to interpret the court ruling as a permanent cancellation of the proposed policy. The legal case could continue, and immigration rules can change through further court decisions or government action. International students currently studying in the United States or preparing to apply should therefore continue following official guidance from US immigration authorities and their universities. For students planning long academic programmes, keeping up with immigration developments remains particularly important.
