What could change for F-1 students under the 2026 Duration of Status final rule?
The Department of Homeland Security published a final rule that would replace the longstanding Duration of Status, or D/S, admission framework for F-1 students with fixed periods of admission. If the rule takes effect as published, students admitted under the new system generally would receive a specific Admit Until Date on Form I-94 instead of the familiar “D/S” notation.
If implemented as published, the change would affect when an F-1 student may need an Extension of Stay, how post-completion OPT and STEM OPT interact with authorized stay, what can happen after international travel, and how certain transfers, educational objectives and additional degree programs are treated.
The short answer
If implemented as published, a new F-1 admission generally would extend through the program end date on Form I-20, but for no more than four years at one time, plus an additional 30-day period for departure or another permitted immigration step. A student who legitimately needs additional time may need both an updated Form I-20 and an Extension of Stay filed with USCIS. Students already maintaining F-1 status under D/S when the rule becomes effective would be covered by separate transition provisions.
Current status as of September 8, 2026
September 15, 2026 remains the effective date printed in the DHS final rule. The effective-date issue, however, remains unresolved.
On August 4, 2026, the U.S. Government Accountability Office concluded that the September 15 date does not provide the 60-day delay required for a major rule under the Congressional Review Act because the Senate received the rule on July 20. The final rule states that if congressional review changes the effective date, DHS will publish a document establishing the actual effective date or terminating the rule.
Separately, a coalition of higher-education organizations and unions is challenging the rule in federal court. The U.S. District Court for the District of Massachusetts heard oral argument on a request for preliminary relief on September 3, 2026. As of this September 8 update, the challenge remains pending. Before relying on the September 15 implementation date, students and institutions should check for a later court order or Federal Register notice.
How the 2026 final rule would change F-1 Duration of Status
Duration of Status — D/S
Under the traditional F-1 framework, Form I-94 commonly shows D/S. Authorized stay is tied to continued compliance with F-1 requirements while completing the approved course of study and authorized practical training rather than to one fixed calendar expiration date.
Fixed Admit Until Date
If the rule becomes effective as written, a student generally could be admitted for the period needed to complete the program shown on Form I-20, but for no more than four years at one time, followed by the additional departure period provided by the regulation.
The four-year maximum is an admission limit, not a four-year degree limit. A legitimate degree can last longer, but additional authorized time could require an Extension of Stay instead of continuing automatically under D/S.
Some F-1 categories would remain subject to shorter limits. Under the final text, students in English-language training programs are subject to a 24-month aggregate admission limit, while F-1 study at a public high school remains subject to the statutory aggregate limit of 12 months.
What would happen to F-1 students who already have D/S?
The final rule includes a transition provision for F and J nonimmigrants who were admitted for D/S and are properly maintaining status when the rule becomes effective. It does not simply convert every existing F-1 D/S record into an expiration on the rule's effective date.
Under the published transition text, a qualifying F-1 student generally could remain until the later of the applicable Employment Authorization Document expiration date or the program end date on the Form I-20 covered by the transition rule.
Transition period at a glance
- Applies to qualifying students already maintaining D/S.
- Uses applicable I-20 or EAD dates.
- Underlying transition admission is capped at four years from the effective date.
- The applicable 60-day F-1 departure period may follow.
A student whose current I-94 shows D/S should not treat September 15 as an automatic personal expiration date. The student's position depends on the rule becoming effective, continued maintenance of F-1 status and the applicable I-20 or EAD dates.
International travel, a new admission, a request for additional time, a new course of study or an OPT/STEM OPT filing can change the analysis.
How fixed F-1 I-94 dates and the four-year maximum would work
If fixed admission replaces D/S, Form I-94 becomes a direct calendar-control document. A student admitted under the new framework would need to monitor the Admit Until Date in addition to the program dates on Form I-20.
Two-year master's program
If Form I-20 reflects a two-year course of study, the admission generally could follow that shorter program period. The four-year limit would not automatically give every student four years.
Five-year PhD program
A five-year academic program could exceed the maximum period granted in one admission. A student who remains eligible and needs additional time for a qualifying reason could need a new Form I-20 and an Extension of Stay.
An extended I-20 would not automatically extend the I-94
Under the fixed-date framework, a DSO's extension of a program end date in SEVIS would not by itself change the student's immigration admission period. When the revised academic timeline extends beyond the authorized admission, a separate USCIS Extension of Stay could also be required.
What would the rule mean for F-2 dependents?
The final rule provides that an Extension of Stay granted to an F-2 dependent may not exceed the authorized admission period of the principal F-1 student. A spouse or child seeking additional F-2 time therefore must have dependent status addressed in connection with the principal student's authorized period.
When could an F-1 student need an Extension of Stay?
If the fixed-admission framework takes effect, a student who needs to remain beyond the authorized admission period could need an Extension of Stay from USCIS. The final rule generally uses Form I-539, or its successor form, for that process.
The final regulation identifies circumstances that can support additional time to complete the current program.
The student must continue to satisfy the applicable F-1 requirements. The DSO must make the appropriate SEVIS update and provide the properly endorsed Form I-20, while the USCIS filing must contain the required evidence, fee and any biometrics required by the governing procedures.
For filing mechanics, supporting documents and the distinction between extending and changing nonimmigrant status, see Form I-539: Extend or Change Your Nonimmigrant Status.
Filing during the 30-day departure period
Under the final text, an Extension of Stay can be timely if USCIS receives it before the authorized admission period expires, including the 30-day departure period provided by the new framework.
If USCIS receives the Extension of Stay during those final 30 days, the student may continue a full course of study while the application is pending, but may not continue or begin practical training or other employment merely because the Extension of Stay is pending.
How would the 2026 final rule affect OPT and STEM OPT?
The final rule would not abolish post-completion Optional Practical Training or the 24-month STEM OPT extension. Instead, it would change how employment authorization and the student's authorized period of F-1 stay work together.
Qualifying D/S transition cases
A qualifying F-1 student recommended for post-completion OPT who timely files Form I-765 on or before March 18, 2027 would not be required to file Form I-539 solely for the requested period of post-completion OPT.
Comparable temporary relief applies to qualifying STEM OPT applicants who meet the transition filing conditions. DHS reserved authority to extend this temporary I-539 exemption in six-month increments through a Federal Register notice.
Outside the transition exemption
The final regulatory text requires an F-1 student recommended for post-completion OPT to apply for employment authorization and either apply for an Extension of Stay with USCIS or seek a new admission through CBP after travel abroad.
The student may not engage in post-completion OPT unless the employment authorization is granted.
The new framework therefore would create two separate immigration requirements to track: authorization to work and authorization to remain in F-1 status for the requested practical-training period.
The D/S final rule does not replace the separate OPT unemployment limits. Post-completion OPT retains its 90-day aggregate unemployment limit, while regular OPT plus STEM OPT has a 150-day aggregate unemployment limit. See OPT and STEM OPT Unemployment Days: the 90/150-Day Rule.
How could international travel change an F-1 student's position?
If the final rule is implemented, a student protected by the D/S transition provisions could leave the United States and return through CBP under the fixed-admission framework. A new admission could therefore produce an I-94 with a specific expiration date even though the student's earlier I-94 showed D/S.
If a student covered by the D/S transition leaves the United States before filing a post-completion OPT or STEM OPT application and is then admitted with a fixed period of admission, the final rule requires the student to file both:
- Form I-765 for employment authorization; and
- Form I-539, or its successor form, for the applicable Extension of Stay.
After every admission, retrieve the new electronic I-94 and verify both the class of admission and the Admit Until Date. Under a fixed-period framework, an incorrect I-94 date can create a concrete immigration deadline.
How would the final rule affect transfers, majors and additional degrees?
The 2026 final rule contains changes that go beyond admission dates. It also includes restrictions involving school transfers, educational objectives and progression between academic levels.
Below graduate level
Under the published text, an F-1 student below the graduate degree level generally could not transfer schools or change educational objectives during the first academic year unless SEVP authorizes an exception for qualifying extenuating circumstances.
Graduate level and above
An F-1 student at the graduate degree level or above may not change educational objectives at any point during the program of study.
A graduate student also generally may not transfer during the program, although SEVP may authorize an exception to the transfer restriction for qualifying extenuating circumstances.
Programs at the same or a lower educational level
Under the published text, a student who completes a U.S. F-1 program after September 15, 2026 at one educational level generally may not maintain, obtain or be admitted in F-1 status for another program at the same or a lower educational level. Progression to a higher educational level remains possible if the student otherwise satisfies the F-1 requirements.
Implementation caveat: until September 14, 2028, DHS may delay or suspend implementation of specified provisions governing school transfers, educational objectives and educational levels if DHS determines implementation is infeasible. Any such action must be announced through the Federal Register and SEVP channels.
What should F-1 students check now?
Because the final rule is not yet in effect as of September 8, students should focus on document review and timeline planning rather than file Form I-539 automatically.
Download the current I-94. Confirm whether it shows D/S or a calendar Admit Until Date.
Check Form I-20. Verify the actual program end date on the immigration document.
Identify transition eligibility. A current D/S student is not in the same position as a student seeking a new admission.
Map OPT/STEM OPT dates. March 18, 2027 is important for qualifying transition cases under the published rule.
Review travel before departure. Re-entry could create a new fixed-date I-94 and alter filing requirements.
Plan program extensions early. An updated I-20 may be necessary but may not be sufficient by itself.
Recheck academic changes. Transfers, majors and additional degrees may be affected by separate provisions.
Check for new legal developments. Review later court orders and Federal Register notices before acting.
F-1 Duration of Status 2026: FAQ
Does my current F-1 status automatically expire on September 15, 2026?
No. Under the published final rule, qualifying students admitted for D/S who are properly maintaining F-1 status when the rule becomes effective would be covered by transition provisions. Their existing D/S admission would not simply turn into a September 15 expiration date.
Does the four-year rule mean I must finish my degree within four years?
No. Four years is generally the maximum fixed admission period that could be granted at one time. A legitimate academic program can last longer, but additional authorized time could require an Extension of Stay.
Would every F-1 student on OPT need Form I-539?
No. The final rule contains temporary transition relief for certain students already maintaining D/S. Outside that transition exemption, a student recommended for post-completion OPT must apply for employment authorization and either file for an Extension of Stay with USCIS or seek a new admission through CBP after travel abroad.
Would the F-1 departure period change from 60 days to 30 days?
Generally yes for students admitted under the new fixed-period framework if the rule is implemented as published. Qualifying F-1 students covered by the D/S transition provision would retain the 60-day period specified in the transition rule.
Could international travel change my D/S transition position?
Yes. If the final rule becomes operative, re-entry can result in a fixed-date admission. The regulation specifically provides that a transition student who leaves before filing for post-completion OPT or STEM OPT and then returns with a fixed admission must file both Form I-765 and Form I-539 for the applicable practical-training period.
