DHS Ends "Duration of Status" for F-1 Students: What the New Fixed-Period and Extension-of-Stay Rule Means for OPT and STEM OPT

On July 17, 2026, DHS published a final rule in the Federal Register titled "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." It eliminates the decades-old "duration of status" (D/S) framework for F (academic students), J (exchange visitors), and I (foreign media representatives) nonimmigrants, replacing it with a fixed admission period and a new extension-of-stay process. The rule takes effect September 15, 2026 — and it reaches directly into post-completion OPT and STEM OPT, which is why every F-1 student and recent OPT grad should understand it now, not after their SEVIS record changes underneath them.

"DHS is amending its regulations to change the admission period in the F, J, and I classifications from duration of status to an admission for a fixed time period, and additional changes to admission and extension requirements." — DHS, Federal Register, 91 FR 44976 (July 17, 2026)Federal Register, Document 2026-14439

What "duration of status" was, and what replaces it

Under the old rule, F-1 students were admitted for "duration of status" — an open-ended period tied to actively pursuing a full course of study (and, afterward, authorized practical training), with no fixed expiration stamped on entry. That flexibility is gone. Under the final rule, F students are instead admitted for a fixed period tied to the program length on their Form I-20, and anyone needing more time — to finish a program, start a new one, or begin post-completion OPT or STEM OPT — must proactively apply to extend it.

How long the new fixed period lasts

• Standard F students: admitted for the length of the program of study on the Form I-20, not to exceed 4 years, plus a 30-day period to arrive before the program start date and a 30-day period to depart afterward.
• English language training programs: capped at a 24-month admission period, plus a 30-day departure period.
• Public high school students (including charter or other taxpayer-funded schools): limited to an aggregate of 12 months to complete the course of study.
• Border commuter students: continue to be admitted with a fixed date of admission, unchanged in mechanism.
• J-1 exchange visitors: also move from duration of status to a fixed admission period.
• I nonimmigrants (representatives of foreign information media): admitted for up to 240 days.

The new Extension of Stay requirement — including for OPT and STEM OPT

This is the change that reaches every OPT and STEM OPT applicant going forward: needing more time to complete a program, start a new one, or begin post-completion OPT or STEM OPT now requires filing Form I-539, "Application to Extend/Change Nonimmigrant Status," with USCIS — including the required fee and biometrics — before the fixed admission period expires. This is an entirely new step layered on top of the existing OPT application (Form I-765); filing OPT alone is no longer automatically sufficient to establish lawful presence past the fixed admission date in every scenario (see the cap-gap exception below).

The post-completion departure window got shorter

F students now have 30 days to depart the U.S. after completing their program or their post-completion OPT/STEM OPT — down from the previous 60-day period. Worth flagging precisely because it is easy to conflate: this 30-day SEVP departure window is a different regulation from the discretionary 60-day grace period for H-1B, L-1, O-1, TN, and similar nonimmigrant workers under 8 CFR 214.1(l)(2) — the one DHS separately proposed eliminating in RIN 1615-AD22 (see our earlier article). Both changes point the same direction — less post-status runway — but they sit in different parts of the CFR and affect different visa categories.

New restrictions on changing major, level, or transferring schools

• Below graduate level: cannot change educational level or major, or transfer schools, during the first year of the program, absent an SEVP-authorized exception for extenuating circumstances.
• Graduate level and above: cannot change educational level, change major, or transfer schools at any point during the program (transfers may still get an SEVP exception; level and major changes do not have that carve-out in the rule).
• After completing a program: students cannot move to a program at a lower educational level, or to another program at the same educational level.

Transition period: if you are already in the U.S. on a D/S admission

• Present in the U.S. on September 15, 2026 (the effective date): you may remain without filing an EOS until your Form I-20 Program End Date, or the end of your post-completion OPT/STEM OPT valid on that date — capped at November 14, 2030 (four years plus a 60-day departure period).
• You travel and re-enter after the effective date: you are readmitted with a new fixed period based on your I-20 Program End Date, up to a 4-year maximum plus a 30-day departure period.
• You are in the U.S. on September 15, 2026 and timely filed for post-completion OPT or STEM OPT by March 18, 2027: no separate EOS filing is required.
• You travel before filing for OPT and are readmitted with a new fixed period: you must file both an EOS application and the OPT/STEM OPT application.

What this means for the OPT-to-H-1B cap-gap

For students who are the beneficiary of a timely filed cap-subject H-1B petition and are eligible for a cap-gap extension, DHS built in an explicit carve-out: no EOS application is required. Cap-gap students may remain in F-1 status until their H-1B petition is approved or April 1 of the relevant fiscal year, whichever comes first. If you are mid-OPT and already have an H-1B petition filed on your behalf, this rule does not add a new filing burden on top of cap-gap — but confirm your specific dates with your DSO, since the interaction between a fixed admission period and cap-gap status is new territory operationally, even where the rule itself preserves the existing protection.

Bottom line

If you are on F-1 status — especially on post-completion OPT or STEM OPT, or about to apply for it — the open-ended "duration of status" you may be used to is going away on September 15, 2026. Check your SEVIS record and I-20 Program End Date, talk to your DSO about whether you fall under the transition-period carve-outs above, and if you need more time beyond your fixed admission period, plan to file Form I-539 for an Extension of Stay well before that date arrives. Missing it is no longer a paperwork inconvenience — it is the difference between lawful and unlawful presence.
