F-1 Duration of Status Rule Blocked: What International Students Need to Know
A federal court order has postponed DHS’s fixed-admission-period rule for F-1 students, J-1 exchange visitors, and I nonimmigrants. USCIS says it will keep using the previous rules for now and is not accepting the 09/15/26 editions of Forms I-539 and I-765.
A federal court order has postponed DHS's 2026 rule that would have replaced "duration of status" with fixed admission periods for F-1 students, J-1 exchange visitors, and I nonimmigrants. USCIS now says DHS is preliminarily enjoined from implementing the final rule, the effective date is postponed, and USCIS will proceed under the previous regulatory provisions until the court order changes or the case is resolved.
That means this page has been refreshed from the earlier "rule takes effect Sept. 15" version. The practical message is simple: do not rely on old headlines or saved form links. Check the current USCIS Form I-539 and Form I-765 pages before filing.
What changed
DHS published the final rule, Establishing a Fixed Time Period of Admission and an Extension of Stay Procedure for Nonimmigrant Academic Students, Exchange Visitors, and Representatives of Foreign Information Media, in the Federal Register on July 17, 2026. The rule was scheduled to take effect on Sept. 15, 2026.
On Sept. 14, 2026, the U.S. District Court for the District of Massachusetts issued an order postponing the effective date in Presidents' Alliance on Higher Education and Immigration, et al. v. DHS, case number 26-cv-13799. USCIS says DHS is preliminarily enjoined from taking further action to implement the rule while the order remains in place.
What USCIS says to use now
USCIS says it will proceed under the previous regulatory provisions for now. It also says:
- USCIS continues to accept the 08/28/24 edition of Form I-539.
- USCIS continues to accept the 08/21/25 edition of Form I-765.
- USCIS is not accepting the 09/15/26 editions of Forms I-539 and I-765.
What this means for F-1 students right now
If you are in F-1 status, this update does not mean the whole policy fight is over. It means the fixed-admission-period rule is blocked for now and USCIS says it is following the previous rules while litigation continues.
For most students, the safest next steps are:
- Check your current I-94, I-20, and school records.
- Ask your DSO before making filing or travel decisions.
- Use the current USCIS Form I-539 and Form I-765 pages, not screenshots or old PDFs.
- Watch for future court or DHS updates, because USCIS says DHS disagrees with the order and may implement the rule if the order is lifted.
What this means for OPT and STEM OPT
The court order does not erase the normal OPT and STEM OPT rules. If you are applying for employment authorization, the key immediate issue is the form edition and filing instructions on USCIS's Form I-765 page.

What this means for J-1 exchange visitors and I nonimmigrants
The blocked DHS rule also covered J-1 exchange visitors and representatives of foreign information media in I status. If you are in one of those categories, check your program sponsor, responsible officer, attorney, or employer before assuming a fixed-date admission rule applies to you today.
