University groups and labor unions have filed a lawsuit to block a new immigration rule limiting F-1 and J-1 international student and exchange visitor visas to fixed four-year periods. The lawsuit was filed in the U.S. District Court for the District of Massachusetts. The challenge could significantly delay or prevent the rule’s implementation, which is currently scheduled for September 15, 2026.
What changed
The rule, finalized in July 2026 and effective September 15, is part of the Trump administration’s broader immigration restrictions. On July 17, 2026, the Department of Homeland Security (DHS) issued a final rule amending its regulations to change the period of admission for F, J and I nonimmigrants from duration of status (D/S) to a fixed admission period.
The rule replaces the longstanding D/S framework with fixed admission periods of no more than four years and requires international students and exchange visitors to apply for extensions of stay. It also restricts students’ ability to change educational objectives, transfer institutions, or pursue additional programs of study.
The lawsuit centers on procedural and substantive challenges. The complaint argues that the final rule violates the Administrative Procedure Act because DHS failed to adequately assess its costs and benefits, meaningfully respond to public comments, consider less burdensome alternatives, or justify the rule based on its stated objectives. It also alleges that DHS provided an inadequate public comment period and exceeded its statutory authority.
Why it matters
This case directly affects how you advise F-1, J-1, and I nonimmigrant clients. The final rule limits how long students can study in the United States without obtaining new permission from the U.S. government by eliminating the previous policy known as “duration of status.” Under the old rule, students could remain in the U.S. to complete their program without seeking approval; under the new rule, they must file extension of stay applications before their fixed admission period expires or accrue unlawful presence.
These changes will create significant uncertainty and administrative burdens for international students and exchange visitors and the institutions that support them. The group filing the lawsuit asked for a preliminary injunction stopping the new rule before it is implemented. If the court grants the injunction, the rule would not take effect on September 15, and practitioners could continue advising under the duration of status framework.
Plaintiffs argue it is “arbitrary and capricious,” warning of severe economic and academic consequences, including reduced international student enrollment, weakened university finances and a loss of talent in critical fields. They contend the Department of Homeland Security’s justifications, such as national security, rely on weak anecdotes and that the agency disregarded significant public comments.
Way forward
-
Monitor the litigation closely. The D.C. District Court will decide whether to grant a preliminary injunction before September 15. Track the Presidents’ Alliance website and federal court dockets for updates on the motion schedule.
-
Prepare dual-track filing strategies now. Until the injunction decision is made, plan for both scenarios: continuing duration-of-status admissions if the rule is blocked, or filing timely extension-of-stay applications with USCIS if it takes effect.
-
Review client I-94s and program end dates. If the rule goes into effect, any F-1, J-1, or I nonimmigrant currently in the U.S. will need careful monitoring of their fixed admission period expiration date and timely extensions filed at least 45 days before expiration.
-
Document compliance measures. Advise schools and exchange program sponsors to implement systems now to track fixed admission periods and deadline-trigger alerts to avoid clients accruing unlawful presence by missing extension deadlines.
