The Department of Homeland Security has finalized one of the most significant overhauls to F-1 student regulations in more than three decades. The final rule, published in the Federal Register on July 17, 2026 (91 FR 44976), eliminates “duration of status” (D/S) — the flexible admission framework that has governed international students since 1991 — and replaces it with a fixed admission period tied to a specific expiration date on Form I-94.
The rule takes effect September 15, 2026, 60 days after publication, unless Congress or the courts intervene first.
Under the current system, F-1 students are admitted for as long as they remain enrolled and in status, with no fixed departure date stamped on their paperwork. That ends under the new rule. Going forward, F-1 students (and their F-2 dependents) will receive an “Admit Until Date” (AUD) on their I-94 — a hard deadline based on the program end date listed on their Form I-20, capped at four years, plus a grace period.
Anyone who needs more time — because a degree runs long, a program changes, or additional training is needed — will have to file a formal Form I-539 extension of stay application with U.S. Citizenship and Immigration Services, complete with a fee, biometrics, and the possibility of an interview, before their AUD expires.
Four Changes Schools and Students Need to Track
1. Fixed admission periods. The AUD equals the I-20 program end date, capped at four years, plus a 30-day grace period. Programs genuinely longer than four years will require an extension filing partway through, even for students who are on schedule and made no errors.
2. Shorter grace period. F-1 students lose half their post-completion cushion — the grace period drops from 60 days to 30.
3. A 24-month lifetime cap on ESL study. English language training students are limited to 24 months in the aggregate, counting school breaks, with no extra time granted for illness, disability, or other extenuating circumstances. DHS has confirmed this is a lifetime limit, though study completed before September 15, 2026 won’t count against it.
4. New restrictions on transfers and changing majors or levels. DHS has created a formal concept of “educational objectives” (major or educational level). Undergraduate and below: no transfers or changes within the first academic year, absent a narrow SEVP-approved exception. Graduate level: no changes of educational objective at any point in the program, and transfers are barred outright unless SEVP grants an “extenuating circumstances” exception — a bar DHS added late, in response to comments about students following faculty advisers to new institutions. Separately, students who complete a program on or after the effective date are barred from starting a new program at the same or a lower educational level.
F-1 students already admitted under D/S and physically in the U.S. on September 15, 2026 don’t need to scramble for a new I-94 immediately. But they still must apply for an extension before the earlier of their current program end date or four years from the effective date, and they’ll be subject to the new academic-mobility restrictions to varying degrees. A master’s student whose I-20 lists a program end date of June 2028 must file for an extension before June 2028 if more time is needed — the program end date is the earlier trigger. A PhD student whose I-20 lists a program end date of 2032 must file for an extension before September 15, 2030 — the four-year cap is the earlier trigger, even though the I-20 says the program runs two years longer.
Two triggers move them into the new fixed-date system early: leaving and re-entering the country, or filing for an extension — both of which convert their grace period from 60 days down to 30.
DHS itself estimates $93.3 million in sector-wide training and adaptation costs in year one, and has acknowledged — in unusually blunt language for a rule preamble — that it cannot predict how many prospective students the added friction will deter from choosing the U.S. Schools should expect more advising volume, more USCIS filing deadlines to track per student, and higher legal exposure if extensions are filed late or program end dates are set unrealistically.
