✓ The short version

The rule that would have ended duration of status (D/S) for F, J, and I nonimmigrants did not take effect. A federal court blocked it on September 14, 2026, the day before it was scheduled to begin. For now, F-1 students and J-1 exchange visitors continue to be admitted for duration of status — keep maintaining your program and status as usual, and watch for further developments.

Key Facts

What was scheduled — a DHS final rule would have replaced open-ended duration of status with fixed periods of admission for F (students), J (exchange visitors), and I (foreign media) nonimmigrants, starting September 15, 2026. What happened — on September 14, 2026, the U.S. District Court for the District of Massachusetts issued a preliminary injunction in Presidents’ Alliance on Higher Education and Immigration v. DHS, blocking the rule before it took effect. Where things stand — duration of status remains in place; the court found the plaintiffs likely to succeed on their Administrative Procedure Act claims. What’s next — this is preliminary relief, not a final decision; the government may appeal, so continue to monitor.

1. What the Rule Would Have Changed

For decades, F-1 students and J-1 exchange visitors have been admitted for “duration of status” (often written D/S) — meaning they may remain in the United States as long as they maintain their program and comply with the terms of their status, rather than to a fixed calendar date.

The DHS final rule, scheduled to take effect September 15, 2026, would have ended that framework and instead admitted F, J, and I nonimmigrants for fixed periods of admission. Broadly, it would have:

Because the rule is enjoined, none of these changes are currently in effect.

2. What Actually Happened: The Court Blocked It

On September 14, 2026 — the evening before the rule was set to begin — the U.S. District Court for the District of Massachusetts issued a preliminary injunction in Presidents’ Alliance on Higher Education and Immigration v. DHS. A coalition led by higher-education and international-educator organizations had challenged the rule.

The court postponed the rule’s effective date and preliminarily enjoined DHS and U.S. Immigration and Customs Enforcement (ICE) from taking further steps to implement it while the litigation continues. In granting relief, the court concluded that the plaintiffs were likely to succeed on their claims under the Administrative Procedure Act (APA).

The practical effect: the rule did not take effect on September 15, 2026, and the current duration-of-status framework stays in place for now.

3. What It Means for You Now

Question Under the blocked rule Current reality
How long are you admitted? A fixed period, with an end date Duration of status as long as you comply
Must you file an extension of stay? Generally yes, to continue Not under this rule
F-1: change objective / transfer / add a program? New limits would apply Those limits are not in effect
F-2 / J-2 dependents Same fixed-period framework Continue under D/S with the primary

In short, if you are an F-1 student or J-1 exchange visitor in valid status, the day-to-day rules have not changed because of this rule: you continue on duration of status, you are not required to file an extension of stay to comply with the blocked framework, and the new F-1 limits on changing programs or transferring are not in force. As always, you must continue to maintain your status — a full course of study, a valid I-20 or DS-2019, timely reporting through your school or sponsor, and lawful employment only where authorized.

5. Frequently Asked Questions

Did duration of status end on September 15, 2026?+
No. On September 14, 2026, a federal court preliminarily enjoined the DHS rule that would have replaced duration of status with fixed periods of admission for F, J, and I nonimmigrants. Because the rule was blocked before it took effect, duration of status remains in place for now, and F-1 students and J-1 exchange visitors continue to be admitted for D/S as long as they comply with their program.
As an F-1 student, do I need to apply for an extension of stay now?+
Not under the blocked rule. The fixed-admission-period system that would have required extension-of-stay applications did not take effect. You continue on duration of status as long as you maintain your program and status. If your specific situation involves a separate need (for example, a program end date, OPT, or a change of status), confirm what applies to you with an attorney or your DSO.
What would the rule have changed if it had taken effect?+
The DHS final rule would have replaced open-ended duration of status with fixed periods of admission for F (students), J (exchange visitors), and I (foreign media) nonimmigrants, generally requiring them to apply for extensions of stay to continue, and it would have added new limits on F-1 students changing their educational objective, transferring schools, or pursuing additional programs. Because the rule is enjoined, none of those changes are in effect.
Is this decision final, or can the government appeal?+
It is a preliminary injunction, not a final ruling. The court found the plaintiffs were likely to succeed on their Administrative Procedure Act claims and blocked the rule while the case proceeds. The government may appeal or continue to litigate, so the situation can change. Watch for further developments and confirm current status before making decisions.
Does the injunction affect my F-2 or J-2 dependents?+
The rule that was blocked would have applied to F, J, and I nonimmigrants and their dependents. With the rule enjoined, dependents in F-2 and J-2 status continue under the existing duration-of-status framework alongside the primary F-1 or J-1, subject to the usual requirement to maintain status.
I already started preparing an extension application based on the new rule. What should I do?+
Because the fixed-period rule is not in effect, an extension application filed solely to comply with it may be unnecessary. Do not abandon or change any pending immigration filing based on news alone, however — whether you still need a particular application depends on your individual circumstances. Confirm with an immigration attorney or your school's international office before acting.
