DHS Ends F-1 Duration of Status: New 4-Year Limit

Duration of status let your school define your timeline. Your Form I-20 set a program end date, but your admission had no hard expiration, so as long as you stayed enrolled and made progress, your status held. DHS first proposed ending it in 2020, withdrew that proposal in 2021, and has now finalized it.

The final rule moves the clock onto your I-94. From September 15, 2026, a new F-1 student gets an admit-until date, the same date-specific stamp that H-1B workers and visitors already receive. Your admission runs to the program end date on your I-20 or four years, whichever is shorter, plus a 30-day grace period. That four-year ceiling covers everything, including your OPT.

You file an extension of stay with USCIS before your admit-until date expires. Plenty of programs run past four years, and most PhDs do, so a step that never existed before now sits in the middle of the degree: Form I-539, with a filing fee, a biometrics appointment, background and fraud screening, a processing wait, and a decision that can come back with a request for evidence.

You can no longer rely on your school to extend you the way a Designated School Official could update an I-20. The decision belongs to USCIS now. The agency itself expects roughly 414,000 additional I-539 filings a year, so plan for the queue rather than against it, and file early.

The grace period after your program ends drops from 60 days to 30. That is half the window to depart, transfer, change status, or start your OPT paperwork, so the calendar gets tighter the moment you finish.

English-language training now caps at 24 months total, measured from your program start and counting school breaks. If you are studying English before a degree program, that ceiling is firm.

The change that turns a missed deadline into a lasting problem is unlawful presence. Until now, an F-1 student started accruing unlawful presence only after USCIS or an immigration judge made a formal finding of a status violation. Under the new rule, it begins the day your admission period expires, on its own.

Cross 180 days and you face a three-year bar on reentry. Cross a full year and it becomes ten. A late extension is no longer a quiet paperwork fix. It can close the door on coming back, which is why the new dates deserve real attention.

The rule also tightens how you move inside the system. As an undergraduate, you cannot change your major or education level, or transfer schools, during your first academic year, unless SEVP grants an exception for something like a school closure. As a graduate student, you cannot change your educational objective at any point, and a transfer needs an SEVP exception.

You also cannot step down into a program at the same or a lower level after finishing one. DHS may delay these mobility limits until September 14, 2028 if the rollout proves unworkable.

If you are in the US on duration of status, you do not need to rush to USCIS on September 15. A transition rule lets you keep your status until the program end date on your current Form I-20, or your OPT work-permit end date if that is later, up to four years from the effective date, which lands on September 15, 2030. To stay past that, you file an extension like everyone else. During the transition you keep your old 60-day grace period, not the new 30-day one, until the first time you travel and reenter or file an extension, and either of those switches you to the shorter 30-day grace.

Two dates matter for this group. First, travel: if you leave and reenter on or after September 15, 2026, CBP admits you with a fixed date on a new I-94 and the shorter 30-day grace, so a single trip moves you onto the new system. Second, OPT: if you file for OPT or STEM OPT on time, by March 18, 2027, you do not need a separate I-539 for that training period.

The planning picture is what really shifts. Program end dates, OPT start and end, conference travel, a summer trip home, a switch from a master's to a PhD, all of it now runs against a date on your I-94 instead of an open-ended status. Know your admit-until date the moment you get it, and if your program will pass four years, map your I-539 filing months ahead rather than in the final weeks.

The same clock applies to what comes after study. If you are weighing your next step after F-1 and OPT, whether that is the H-1B, the O-1, or an employment-based green card, start that plan early, because the runway is now measured rather than assumed. If that is you, our eligibility check maps which paths fit your profile in a few minutes.

The rule takes effect September 15, 2026, but it may not arrive untouched. It is a "major rule" subject to congressional review, and it will draw legal challenges. NAFSA, the main association for international educators, called it "misguided and unnecessary," and immigration attorneys widely expect suits arguing the rule is arbitrary under the Administrative Procedure Act.

A court could pause or push the date. None of that is certain, so the sound approach is to plan around the rule as written and adjust if the courts move it. Watch the SEVP and USCIS pages for implementation guidance as September approaches.
