The F-1 four-year rule is a DHS final rule that replaces open-ended “duration of status” admission with a fixed period of stay — the length of the program, capped at four years — for F, J and I visa holders, effective September 15, 2026.
What happened
The Department of Homeland Security published a final rule in the Federal Register on July 17, 2026, one day after announcing it. The rule ends admission for “duration of status” (the D/S you see on the I-94) for three nonimmigrant categories: F (academic students), J (exchange visitors) and I (foreign media). The effective date is September 15, 2026, and the rule text itself notes that the date can move after congressional review.
Under the new framework, an F-1 student is admitted for the length of the academic program, up to a maximum of four years. If the program runs longer than the authorized period, staying legally is no longer automatic — it requires an extension of stay filed with USCIS.
What changes for you
Three concrete changes:
- Your I-94 gets a date. The arrival record used to read “D/S.” It now carries an end date. Staying past that date without an approved extension puts you out of status.
- Extensions become a filing. To stay beyond the authorized period, the route is Form I-539 (Application to Extend/Change Nonimmigrant Status), filed with USCIS. That means supporting documents, processing time, and planning months ahead — the decision does not come back the same week.
- The grace period is cut in half. The window to wrap up and depart after finishing the program (or OPT) drops from 60 days to 30 days.
If you are a PhD candidate, a student stacking a bachelor's into a master's, or anyone whose program plus practical training realistically runs past four years, this is a calendar problem before it is anything else. The same is true if you have dependents in F-2 status, whose authorized stay tracks yours.
None of this changes what you are allowed to study or where you can work. It changes the timeline — and in immigration, the timeline is what quietly breaks when nobody is watching it.
In practice
- Once the rule takes effect on September 15, pull your I-94 record at i94.cbp.dhs.gov and read the admit-until date. It is free.
- If your program will run past four years, start assembling the I-539 package months out, not weeks out.
- Plan around a 30-day grace period, not 60. Decide your next step before the program ends, not after.
