The admission framework that has governed F-1 students for decades ends in two weeks. DHS published a final rule in the Federal Register on July 17, 2026 establishing a fixed time period of admission and a formal extension of stay procedure for F academic students, J exchange visitors, and I representatives of foreign information media. It takes effect Sept. 15, 2026.
Until that date, F students continue to be admitted for “duration of status” (D/S) — an open-ended admission lasting as long as the student pursues a full course of study at an SEVP-certified school, plus authorized practical training. After Sept. 15, that ends. Under the final rule, an F student is admitted for a fixed period based on the program length listed on their Form I-20, not to exceed four years, plus a 30-day period for arrival and an additional 30-day period for departure. J-1 exchange visitors face a comparable cap of up to four years; I nonimmigrants are limited to up to 240 days.
The operational consequence is the part worth reading twice. Under the new rule, an F student must file an extension of stay (EOS) application with USCIS in order to take additional time to complete a program of study, to begin a new program of study, or to engage in post-completion OPT or STEM OPT. Practical training that previously flowed from the existing D/S admission now requires an affirmative filing that USCIS must adjudicate. That is a new fee, a new processing time, and a new denial risk sitting directly in the path between graduation and the first day of work — on the exact timeline where OPT start dates are already tight.
The forms follow the rule. USCIS will publish revised 09/15/26 editions of Form I-539 (Extend/Change Nonimmigrant Status) and Form I-765 (Employment Authorization) on Sept. 15, with no grace period, precisely because the revised editions are what allow the agency to apply the final rule. The prior editions are rejected if postmarked or submitted on or after that date, and the new editions cannot be filed before it.
Students already in the United States on a D/S admission are not exempt from the transition. DHS has directed those admitted before the effective date to calculate their status expiration date under the new framework rather than assuming their existing admission carries forward unchanged. Anyone currently on F, J, or I status should determine that date now, not at the point they need to travel or file.
DHS is running a live SEVP stakeholder webinar on the rule today, Monday, Aug. 31, 2026, from 2 to 3 p.m. EDT, aimed at students and designated school officials. The rule is also classified as a major rule subject to congressional review, which leaves a procedural path for change, but nothing about that changes the planning posture for the next two weeks.
For the many NIW and EB-1A applicants who begin in F-1 status and bridge to a green card through OPT and STEM OPT, this rule adds a USCIS adjudication to a stage that used to be automatic — one more reason to start the employment-based petition earlier rather than treating OPT as reliable runway.
