Buried inside the fixed admission period rule that takes effect on 15 September 2026 is a change that will reach more people than the four-year admission cap: the F-1 post-completion grace period shortens from 60 days to 30, aligning it with the J-1 category.
Why 30 days is tighter than it sounds
The grace period is the window after a program ends in which a student can remain lawfully in the United States. It is when people decide whether to depart, transfer, change level, change status, or begin practical training. Halving it does not just compress travel planning. It compresses the decision itself, and every one of those options has its own filing requirements.
Who keeps 60 days, and for how long
The transition provisions are specific. F-1 students who were admitted for duration of status before 15 September 2026 generally continue to have the 60-day grace period. That continues until one of two things happens:
- they depart and are readmitted on or after 15 September 2026, or
- USCIS approves an extension of stay for them.
Either event produces a new Form I-94 with a date-specific Admit Until Date, and from that point the 30-day grace period applies. For J-1 holders the grace period remains 30 days regardless, because it already was.
The practical consequence is that a single international trip can change a student’s grace period from 60 days to 30. That is worth knowing before booking travel, not after.
What this means for OPT
DHS has published specific guidance on how practical training interacts with the transition.
Current F students who were admitted under duration of status, are present in the United States on 15 September 2026, and timely file for post-completion OPT or STEM OPT by 18 March 2027 do not need to file an extension of stay.
Students who travel before filing for OPT or STEM OPT, and are readmitted with a fixed period of admission, must file an extension of stay application together with their OPT application.
Students who are beneficiaries of a timely filed cap-subject H-1B petition and are eligible for a cap-gap extension do not need to file an extension of stay. They may remain in F-1 status until the H-1B petition is approved, or until 1 April of the fiscal year for which H-1B status is requested, whichever comes first.
The date to note
18 March 2027 is the filing deadline that decides whether many current students need a separate extension of stay application at all. It is six months out, and it is easy to miss in coverage focused on the September effective date.
