A federal court has postponed the implementation of the Department of Homeland Security’s 2026 rule that would have ended the longstanding Duration of Status (D/S) framework for F-1 and J-1 students.
The U.S. District Court for the District of Massachusetts issued preliminary relief on September 14, 2026, one day before the rule was scheduled to take effect. The court postponed the rule’s effective date nationwide while the underlying lawsuit continues.
For F-1 students, the immediate practical point is straightforward: the existing D/S framework remains in effect for now. The new fixed-admission system has not taken effect.
What happened to the 2026 D/S rule?
DHS published its final rule on July 17, 2026. The rule was designed to replace D/S admissions with fixed periods of admission and introduce related extension-of-stay procedures and other changes affecting F, J and I nonimmigrants. Its scheduled effective date was September 15, 2026.
A coalition of higher-education, immigration and labor organizations challenged the rule in federal court in Massachusetts.
On September 14, Judge F. Dennis Saylor IV granted preliminary relief postponing the rule’s effective date under Section 705 of the Administrative Procedure Act.
Is the D/S rule cancelled?
No. This distinction matters.
The September 14 order is not a final decision on the entire lawsuit. The judge postponed the effective date but did not vacate the final rule. The order expressly states that the request for vacatur and summary judgment was denied without prejudice to being renewed later.
So the most accurate description is:
The D/S final rule has been postponed nationwide, not permanently eliminated.
What does the injunction mean for F-1 students right now?
Current guidance from university international offices following the ruling states that the existing D/S framework remains in place while the litigation continues.
That means students are not currently subject to the new fixed-admission framework simply because September 15, 2026 has passed.
The new rule’s proposed changes included fixed admission periods, extension-of-stay procedures and additional restrictions affecting educational changes and transfers. Those changes are not currently operative while the effective date remains postponed.
Why was the rule challenged?
The court’s preliminary ruling focused heavily on the Administrative Procedure Act.
The judge found that DHS had not adequately explained several important aspects of the rulemaking. The decision identifies four principal concerns: DHS did not conduct a sufficiently reasoned calculation of benefits and costs, did not meaningfully consider alternatives, did not adequately respond to significant comments, and did not establish a rational connection between the final rule and its stated objectives.
The court ultimately concluded that the plaintiffs had demonstrated a substantial likelihood of success on their APA claims.
These are findings made at the preliminary-injunction stage, rather than a final merits judgment.
What changes were supposed to happen under the new rule?
The final rule would have moved F and J nonimmigrants away from the traditional D/S framework toward fixed admission periods and extension-of-stay procedures.
Among the rule’s provisions were limits generally tied to a program’s length, with an admission period not exceeding four years. The rule also included changes affecting F-1 transfers and changes in educational objectives.
For students, that would have created a substantially different administrative framework involving fixed admission periods and, in relevant circumstances, USCIS extension-of-stay filings.
Those changes are postponed for now.
Does this mean F-1 students can ignore their immigration requirements?
No. The injunction does not remove the normal requirements for maintaining F-1 status.
Students should continue to follow the terms of their F-1 program, communicate with their Designated School Official when necessary, maintain required enrollment and follow applicable rules for employment, travel and program changes.
The court’s order postpones the new D/S rule. It does not suspend the broader F-1 immigration framework.
Does the injunction change CPT or OPT rules?
The injunction itself is not a new CPT or OPT authorization.
Students should not treat the D/S ruling as permission to work outside the normal requirements governing CPT or OPT.
The importance for students is primarily that the new fixed-admission system has not taken effect. Current university guidance also states that there are no immediate changes to the existing OPT process as a result of the September 14 injunction.
CPT and OPT eligibility should continue to be evaluated under the applicable regulations, school procedures and DSO guidance.
Should F-1 students still monitor their I-20 and immigration documents?
Yes. Students should continue monitoring their Form I-20, Form I-94, passport, visa and other immigration documents and should contact their DSO when a situation involves a transfer, program change, employment authorization, travel or status issue.
The fact that the D/S framework remains in place does not mean students should stop monitoring regulatory developments.
What happens next?
The litigation is continuing. Current institutional and international-education updates identify October 2, 2026 as the next court date. It is better understood as a further step in the litigation rather than a date on which the current injunction automatically expires.
The government is also expected to continue challenging the injunction. Because the case remains active, the legal position could change.
Students should therefore rely on current official guidance rather than older explanations of what the September 15 rule would have done.
What should F-1 students do now?
For most students, the practical response is to continue following their existing F-1 requirements and stay informed about changes.
For matters involving a transfer, change of educational objective, OPT, CPT, travel, reinstatement or a potential status issue, students should speak with their DSO and use the current USCIS instructions applicable to their filing.
USCIS continues to publish the instructions and editions for its immigration forms, and those instructions can change.
