If you study in the United States on an F-1 visa, you already track plenty of dates.
You may be watching your program end date, travel plans, OPT window, and immigration documents. Starting this September, the end of your authorized stay may become even more important.
For years, many F-1 students entered the United States under Duration of Status, or D/S. This system allowed students to remain while they maintained valid status and continued an authorized program or practical training.
Starting September 15, 2026, DHS will replace that system for F, J, and I nonimmigrants with fixed periods of admission.
USCIS will also introduce new editions of Form I-539 and Form I-765 on the same date. The agency will not provide a grace period for older editions.
If you are approaching graduation, planning OPT, extending your program, or traveling abroad, this change deserves attention.
What changes for F-1 students on September 15?
Under the current D/S system, many F-1 students do not receive a specific end date for their stay.
Instead, they can generally remain in the country while they maintain status and follow the rules of their program.
The new framework changes that approach.
For new F and J admissions, DHS will generally tie the authorized stay to the program end date. The maximum admission period will usually be four years.
If your academic program lasts longer, you may need to request more time from USCIS.
This makes the issue commonly searched as an F1 visa extension much more important.
Technically, students request an extension of F-1 status or stay. They do not extend the visa stamp itself.
That distinction matters because your visa, I-94, and I-20 serve different purposes.
When could an F1 visa extension require Form I-539?
Form I-539, Application to Extend/Change Nonimmigrant Status, will play a larger role under the new system.
An F-1 student may need additional time for several reasons.
For example:
- A degree takes longer than expected.
- Research continues beyond the original program date.
- An academic change extends the program.
- Another valid circumstance requires more time in F-1 status.
DHS allows eligible students to request an extension before their authorized stay expires.
Students who know they need more time should prepare early. In some cases, they may file up to 180 days before the expiration date.
A timely filing may also allow the student to remain in an authorized period while USCIS reviews the request.
The practical takeaway is important: review your I-94, I-20, and USCIS filing timeline together.
Do not wait until graduation week to discover that your immigration timeline needs attention.
If your program may continue beyond your authorized stay, Loigica can help you review your dates and immigration options before the deadline gets too close.
USCIS is also changing Forms I-539 and I-765
USCIS will publish new editions of both forms on September 15, 2026.
The agency will use the revised forms to support the new fixed-period system.
There will be no grace period for older editions.
For Form I-539:
- Applicants may use the 08/28/24 edition before September 15.
- USCIS will reject that edition if filed on or after September 15.
- Starting that day, applicants must use the new 09/15/26 edition.
For Form I-765:
- Applicants may use the 08/21/25 edition before September 15.
- USCIS will reject that edition if filed on or after September 15.
- Starting September 15, applicants must use the new 09/15/26 edition.
USCIS has published preview versions for preparation purposes.
However, applicants should not file the new editions before September 15.
This hard cutoff matters. A filing prepared correctly today could face rejection if someone submits the wrong edition after the transition date.
How do the changes affect OPT and Form I-765?
The new system also affects students planning Optional Practical Training (OPT) or STEM OPT.
The final rule includes transition protections for certain F-1 students who already hold D/S status.
Some qualifying students can file Form I-765 for post-completion OPT or a STEM OPT extension on or before March 18, 2027 without filing a separate I-539 for that period.
Travel may change the situation.
A student who leaves the United States and returns after the new rule begins may receive a fixed admission period.
That new admission can affect which transition rules apply. After the transition period, some students may need to coordinate Form I-539 and Form I-765. That adds another deadline to an already time-sensitive process.
OPT planning often involves graduation, employment, travel, and EAD timing. Students should now add their authorized stay to that checklist.
What happens to students who already have D/S?
If you already maintain F-1 or J-1 status under D/S, the new rule does not treat you exactly like a new arrival.
DHS created transition rules for people who properly maintain status when the rule takes effect.
For many students, the transition period will connect their stay to the program end date on the existing I-20 or DS-2019.
The rule also includes a transitional four-year limit.
Certain F-1 students in this group will keep the existing 60-day departure period during the transition.
Under the new fixed-period framework, F-1 students will generally receive a 30-day departure period.
Travel can again affect this protection. Two students in the same program may therefore have different immigration timelines.Their entry dates, D/S status, travel history, and future filings can all matter.
What should F-1 and J-1 students review now?
You do not need to panic about September 15. You do need to know which dates apply to you:
- Your most recent Form I-94.
- The program end date on your Form I-20 or DS-2019.
- Whether you expect to need additional time to complete the program.
- Any planned international travel after September 15.
- Upcoming OPT or STEM OPT filing dates.
- The correct edition of Form I-539 or I-765 before submission.
- Whether dependents in F-2 or J-2 status also need coordinated filings.
Students should also avoid relying on old filing habits. A process that worked under D/S may require different planning under a fixed admission period.
The rule is scheduled to take effect on September 15, 2026. DHS has also noted that it may publish an update if congressional review affects that date.
For an international student, these deadlines can shape much more than paperwork. They may affect graduation, research, employment, travel, and plans built over several years. Knowing your dates early gives you more time to make informed decisions.
If you are an F-1 or J-1 student and are unsure how the new rules affect your extension, OPT filing, or travel plans, contact Loigica to review your immigration timeline and next steps.
