F-1 Duration of Status Is Ending: What International Students Need to Know About the New DHS Rule

Written July 31, 2026

TLDR:

• Starting September 15, 2026, F-1 international students will no longer be admitted for “duration of status” (D/S). Instead, they’ll get a fixed admission date, capped at four years, tied to the program end date on their Form I-20.
• Students who need more time to finish a Ph.D., transfer schools, change majors, or continue OPT will now have to file a formal extension application (and fee) with USCIS instead of simply working with their school’s international student office.
• The F-1 grace period is shrinking from 60 days to 30 days, and there are new restrictions on “lateral” moves between programs.
• If this affects you or your institution, now is the time to review your program timeline and talk to an immigration attorney before the rule takes effect.

A Nearly 50-Year-Old Policy Is Going Away

If you’re an international student in the U.S., or you work at an institution that sponsors them, you’ve probably never had to think much about the phrase “duration of status.” That’s kind of the point. Since 1978, F-1 students have been admitted to the U.S. for as long as it takes to complete their program, as tracked by their school’s designated school official (DSO) through the federal SEVIS database. No countdown clock. No renewal application. Just steady compliance with the rules of your student status.

That changes on September 15, 2026. On July 17, 2026, the Department of Homeland Security (DHS) published a final rule that eliminates duration of status for F-1 students (as well as J-1 exchange visitors and I visa holders) and replaces it with a fixed period of admission. This new rule has a hard end date, with a maximum of four years, printed right on your immigration record. If this sounds like a technical, in-the-weeds change, that’s because it is, but it has real consequences for anyone planning to study, train, or work in the U.S. on an F-1 visa.

What Changed About F-1 D/S, Exactly?

Under the old system, an F-1 student’s Form I-94 simply said “D/S”, duration of status. As long as the student stayed enrolled and followed the rules, they didn’t need to reapply for permission to remain in the country, even if their degree took longer than expected.

Under the new rule:

• F-1 students will be admitted for a fixed period tied to their program length, as listed on their Form I-20, capped at four years, even if their program (like many Ph.D. programs) typically takes longer.
• Anyone who needs more time than their fixed admission period must file an Application to Extend/Change Nonimmigrant Status (Form I-539) with USCIS, along with the filing fee, before their status expires.
• The grace period to leave the U.S. (or transition to a new status) after finishing a program is shrinking from 60 days to 30 days.
• New restrictions limit certain “lateral” or “reverse” moves. For example, completing one degree and starting a new program at the same or a lower academic level.
• DHS has said it will grant extensions only for specific reasons, such as a “compelling” academic or medical need, though the rule doesn’t spell out clear standards for how those requests will be evaluated.

DHS has framed the change as closing a loophole that allowed some students to remain in the U.S. indefinitely without routine government review, and Secretary Markwayne Mullin has described the prior system as having “compromised national security” over the decades it was in place. Critics — including higher education associations, immigration attorneys, and members of Congress from both parties — have pushed back, arguing that international students are already closely tracked through SEVIS and that the new process mainly adds paperwork and delay rather than security.

Who This Affects

Current and incoming F-1 students. If you’re already in the U.S. on F-1 status and properly maintaining it as of September 15, 2026, you’ll transition to a fixed end date based on your I-20 program end date; not an immediate deadline, but a real one to plan around. If you’re admitted after the effective date, you’ll start with a fixed period from day one.

Students in longer programs. The four-year cap doesn’t map well onto academic reality. Many bachelor’s degrees run past four years, and the typical Ph.D. takes closer to six. Students in these programs, and international medical graduates completing multi-year residencies or fellowships, are the most likely to need an extension application partway through their studies.

Students who transfer, change majors, or add a degree. Moving from a community college to a four-year university, switching from an English-language program into a degree program, or picking up a second degree will now typically require USCIS approval rather than a simple SEVIS transfer handled by your school.

Students relying on OPT. Optional Practical Training (the post-graduation work authorization many F-1 students use to gain U.S. work experience) intersects with this rule in ways still being clarified. Students planning to use OPT or STEM OPT should watch this closely and coordinate timing with their DSO.

Schools and employers. Universities, colleges, and the employers who hire F-1 graduates will feel this too, through a likely surge in extension filings, more administrative coordination, and added uncertainty for students deciding whether to enroll in the U.S. at all.

What You Should Do Next

This rule creates real deadlines where none existed before, and USCIS is already dealing with significant processing backlogs, so timing matters more than ever.

• Know your fixed admission date. Once the rule takes effect, check your I-94 and I-20 to understand exactly when your authorized stay ends.
• Plan extension filings early. If your program is likely to run past your fixed admission period, an extension application typically needs to be filed before your status expires. Waiting until the last minute is riskier under this system than it was under D/S.
• Talk to your DSO and consider talking to an attorney, too. Your school’s international student office will be a first line of information, but for anything involving a Ph.D. timeline, a transfer, a change of major, or an OPT plan, an immigration attorney can help you build a timeline that avoids gaps in status.
• Employers should get ahead of OPT and cap-gap planning. If you sponsor F-1 employees on OPT or STEM OPT, review expiration dates now and coordinate with your immigration counsel on extension and H-1B timing.

Planning Ahead in a Fixed-Deadline World

Immigration status shouldn’t come down to a paperwork deadline nobody warned you about. This rule adds a layer of complexity, and a real risk of falling out of status through no fault of your own, to a process that used to run quietly in the background. Whether you’re a student trying to finish a degree, a physician completing training, or a school trying to support your international community, this is exactly the kind of change worth getting ahead of rather than reacting to.

Nobody should navigate immigration alone, and that’s especially true right now. If you have questions about how this rule affects your specific timeline, Berardi Immigration Law is here to help you sort through it. Click here to book a consultation today.

Frequently Asked Questions

Q: I’m currently an F-1 student admitted for “duration of status.” Do I need to do anything right now?

Not immediately, but you should find out your program end date on your Form I-20 and understand how the transition provisions apply to you. If you’re maintaining status properly when the rule takes effect on September 15, 2026, you’ll generally keep your current program end date as your new fixed admission date, capped at four years from the effective date, but it’s worth confirming your specific situation with your DSO or an attorney rather than assuming.

Q: What happens if my program takes longer than my fixed admission period?

You’ll need to file an extension of stay application with USCIS before your authorized period ends, along with the required fee and supporting documentation showing your continued eligibility. Because USCIS processing times can run well beyond the transitional protection period the rule provides, filing as early as possible is strongly advised.

Q: Does this affect Optional Practical Training (OPT)?

It can. Because OPT timing is now tied to your fixed admission period rather than an open-ended D/S window, students should coordinate the timing of any OPT or STEM OPT application closely with their DSO, and be aware that separate policy discussions are underway about the future scope of OPT itself. If you’re unsure how this affects your specific OPT plans, it’s worth a conversation with an immigration attorney.
