A federal judge has blocked a Department of Homeland Security (DHS) rule that would have ended the long-standing "duration of status" framework for international students in the United States.

The decision halts, for now, one of the most consequential changes to the US student visa system in decades. Under the current framework, students and exchange visitors admitted with "duration of status" — marked as "D/S" on their admission records — may remain in the country for as long as they maintain valid student status and continue making normal progress toward completing their course of study. The DHS rule sought to replace that open-ended arrangement with fixed time limits.

What the rule would have changed

The blocked DHS rule would have eliminated duration of status and instead imposed fixed maximum periods of admission for F, M and J visa holders. Students would have needed to apply for extensions before reaching those limits, rather than simply maintaining their status while enrolled. The change would have applied to hundreds of thousands of international students studying at US universities, colleges and vocational institutions.

The rule's opponents argued that replacing duration of status with fixed admission periods would create new bureaucratic hurdles, add processing backlogs and make the United States a less attractive destination for foreign students compared with competing study destinations such as Canada, Australia and the United Kingdom.

What the court decision means

With the judge's order blocking the rule, the existing duration of status framework remains in place. International students on F, M and J visas do not, at this time, need to comply with the fixed-duration admission limits the DHS rule would have introduced. The court's action stops the rule from taking effect while the underlying litigation proceeds.

The ruling does not change other core obligations that already apply to student visa holders. Students must still maintain full-time enrolment, comply with the conditions of their visa category and keep their Student and Exchange Visitor Information System (SEVIS) records current through their designated school officials.

Who is affected

The decision directly affects:

• Current F-1 academic students and F-2 dependants
• M-1 vocational students
• J-1 exchange visitors and their J-2 dependants
• Prospective students preparing to apply for US study visas

Universities and exchange programme sponsors, which argued against the rule, also avoid — for now — the administrative burden of tracking fixed admission deadlines for every enrolled international student.

What comes next

Litigation over the rule continues. The judge's blocking order preserves the status quo during the court proceedings, and the DHS could appeal or pursue revised rulemaking. Students and sponsors should track announcements from US Citizenship and Immigration Services (USCIS), the Department of Homeland Security and the Student and Exchange Visitor Program (SEVP) for any further changes to admission rules or compliance requirements.

Readers should rely on official DHS and USCIS channels for authoritative guidance on how the litigation and any future rule changes affect individual circumstances.
