For years, most F-1 students and J-1 exchange visitors have been admitted to the United States for “duration of status,” usually written as D/S. It means you can stay as long as you keep following the rules of your program, without a fixed expiration date attached to your admission. A new government rule was about to change that. Then, one day before it was set to start, a federal court stepped in.
Here is the short version: the change did not take effect, and duration of status still applies today.
What “Duration of Status” Means Right Now
Under the current system, F-1 and J-1 admission does not come with a hard calendar deadline. Your Form I-94, the record of your admission, generally does not show an expiration date for F or J status. Instead, your stay is tied to your program and your compliance with it.
When you need more time, your school’s Designated School Official (DSO) or your program’s Responsible Officer (RO) can update your record in SEVIS and issue new program documents, within the applicable limits. There is no separate application to U.S. Citizenship and Immigration Services (USCIS) just to extend your stay. That is the framework still in place today.
What the New Rule Would Have Changed
The Department of Homeland Security (DHS) finalized a rule that would replace duration of status with a fixed end date, called an “admit until date” (AUD), printed on your Form I-94. Several parts of it would have reshaped day-to-day life for students and exchange visitors:
- A fixed admission period. For many F-1 and J-1 holders, admission would generally be limited by the program length and a four-year maximum, with exceptions depending on the category.
- A new USCIS filing to extend. To stay past your AUD, you would generally file Form I-539 with USCIS, rather than relying on your DSO or RO to update SEVIS. That step could carry a fee and additional processing.
- A shorter wrap-up window for F-1. The post-completion departure period for F-1 students would drop from 60 days to 30 days. J-1 exchange visitors generally already have a 30-day period.
- New limits on program changes and transfers. Changing your educational objective or transferring during your studies would face added requirements, with some exceptions.
- Employment during a pending extension. The rule would protect continued work for certain categories, under set conditions, for a limited time after a timely filing. It would not create a general extension of OPT or STEM OPT employment on its own.
The rule also included special provisions for certain programs and transition rules for people already in the country. Those details vary by situation, which is one reason a fixed-date system would require careful, individual review.
What the Court Did on September 14
The rule was scheduled to take effect on September 15, 2026. On September 14, the United States District Court for the District of Massachusetts postponed that effective date and blocked DHS from putting the rule into effect while the lawsuit continues. The case is Presidents’ Alliance on Higher Education and Immigration v. U.S. Department of Homeland Security.
The court did not cancel the rule or issue a final decision. It paused it. That distinction matters: the rule is on hold, not off the books, and its future is genuinely unsettled. The case could end in a final ruling, an appeal, a revised rule, a settlement, or further agency action.
What This Means for You Today
For now, nothing changes because of this rule:
- Duration of status still governs. You are not being switched to a four-year fixed date just because the rule was published.
- There is no new Form I-539 to file simply because of the rule.
- The shorter 30-day F-1 departure period and the new transfer restrictions are not in effect either. Their start date was postponed along with the rest of the rule.
- Your other obligations stay separate and unchanged. Reinstatements, changes of status, OPT, STEM OPT, CPT, and cap-gap all keep their own rules and deadlines.
Who Should Watch This Most Closely
Some situations would be more exposed than others if a fixed-date system eventually returns. Long programs are the clearest example: doctoral studies, research appointments, and medical training that run past a typical initial admission period. People on OPT or STEM OPT, and anyone planning travel while an application is pending, would also need to plan carefully. If that describes you, this is a good moment to get organized, not to worry.
What Students, Schools, and Employers Can Do Now
The most useful thing you can do is keep your records clean and current. Know your program end dates, your Form I-94, your SEVIS status, your work authorization, your travel history, and any filings you have pending.
It also helps to understand that your documents do different jobs. Your visa generally concerns travel and applying to enter the country. Your Form I-94 reflects your authorized period of admission. Your Form I-20 reflects your F-1 program details. Your Employment Authorization Document (EAD) concerns work. No single one of these answers every question about your status on its own.
Schools and exchange-program sponsors should keep complying with the current D/S framework and can plan operationally for what a fixed-date system would require, while recognizing it is not required today. Employers should keep doing ordinary work-authorization review, since the court’s order does not change how OPT, STEM OPT, CPT, or cap-gap protection work.
Conclusion
The fixed-admission rule did not take effect on September 15, 2026. Duration of status remains the governing framework for F-1 students and J-1 exchange visitors. The court paused the rule rather than striking it down, so whether and when it might return is still unresolved.
There is no reason to rush a filing because of this rule, and no current four-year admission deadline under it. The calmest and smartest move is the same one that helps in almost any immigration situation: keep accurate records, understand your documents, and review new developments before an immediate deadline arrives. We will continue to monitor the litigation and any related DHS or USCIS guidance as new information becomes available.
