Effective 15 September 2026, the United States will end the long‑standing “duration of status” framework for F‑1 international students and introduce fixed admission periods based on the programme length shown on Form I‑20, with a maximum of four years.

Under the previous system, students could remain in the country as long as they maintained enrolment and authorised training, followed by a 60‑day grace period after graduation.

The revised rules allow entry up to 30 days before the programme start date, but the post‑study grace period is reduced from 60 to 30 days.

Specific limits for certain programmes

Students who require more time must apply for an Extension of Stay (EOS) through USCIS, submitting an updated Form I‑20, Form I‑539, paying fees and completing biometrics.

Alternatively, holders of valid visas may leave the US and seek a new admission period upon return, subject to review by US Customs and Border Protection.

Transition provisions and compliance

A transition provision applies to students already in the US when the rule starts; those who file timely applications for post‑completion Optional Practical Training or STEM OPT by 18 March 2027 will be exempt from filing an EOS under the transition.

The new framework requires students to monitor their authorised stay, programme dates and any extension applications more closely, as the open‑ended period is replaced by defined timelines and added compliance steps.
