The F1 duration of status system is coming to an end under a new DHS rule that changes how international students remain in the United States.
For years, many F-1 students were admitted for “D/S,” or duration of status. That meant they could generally remain in the United States while they maintained valid F-1 status, followed their academic program, kept a valid I-20, and complied with student visa rules.
Now, DHS is moving to a fixed admission system.
Starting September 15, 2026, F-1 students will no longer rely on an open-ended D/S notation in the same way. Instead, their I-94 will include a fixed “admit until” date. That date will become a central part of every student’s immigration planning.
This is a major change for students, universities, exchange visitors, and foreign media representatives. But for F-1 students, the impact may be especially serious because school timelines, program changes, OPT, STEM OPT, travel, and extensions must now be managed with much tighter deadlines.
F1 duration of status: what DHS changed
Under the old system, F-1 students were usually admitted for the length of their academic program, as long as they continued to follow the rules of their status.
The new rule replaces that model with a fixed period of admission.
In many cases, the student’s authorized stay will be tied to the program end date listed on the I-20. However, the initial admission period is generally capped at a maximum of four years.
That means a student whose program takes longer than expected may need to take a formal immigration step before the I-94 expires.
This is where the change becomes practical. A university update alone may no longer be enough. Students may need to file an extension of stay with USCIS, usually through Form I-539, if they need additional time to complete their program or continue a lawful path.
Why the I-94 date now matters more
The I-94 controls how long a person is authorized to remain in the United States after admission.
Under the previous D/S system, many F-1 students focused mainly on the I-20, SEVIS record, full-time enrollment, and work authorization rules.
Now, students must also watch the I-94 expiration date carefully. If the I-94 expires before the student completes the program, starts OPT, continues STEM OPT, transfers schools, or changes status, the student may face serious immigration problems.
This can affect status compliance, future visa applications, work authorization, travel plans, and future immigration benefits. The practical message is clear: students cannot wait until the last moment to review their documents.
F1 grace period reduced from 60 to 30 days
Another major change involves the F1 grace period. Previously, many F-1 students had a 60-day grace period after completing their academic program or authorized post-completion practical training.
Under the new rule, the grace period is reduced to 30 days.
That gives students less time to make important decisions after graduation or the end of authorized training. They may need to depart the United States, transfer programs, change status, file another immigration application, or take another lawful step much faster than before.
This shorter timeline can create pressure, especially for students who are coordinating OPT, STEM OPT, H1B strategy, employment-based options, family-based options, or a future green card plan.
When students may need an F1 visa extension
Students may need an F1 visa extension strategy if their academic program, research, practical training, or immigration plan extends beyond the I-94 date.
This is especially important for:
- students in long graduate or doctoral programs;
- students whose program timeline changes;
- students who need more time to complete academic requirements;
- students planning OPT or STEM OPT;
- students considering a change of status;
- students who may travel internationally after the rule takes effect.
In these situations, timing matters. Filing late, traveling without understanding the consequences, or assuming the I-20 solves everything could create avoidable risk.
OPT, STEM OPT, and travel risks
The new rule also affects how students should think about OPT and STEM OPT.
Students should review whether their I-94 date covers the period they need for post-completion training. If the I-94 date does not align with the OPT or STEM OPT timeline, the student may need a coordinated plan before filing or before the current admission period expires.
Travel is another risk. A student who leaves the United States and reenters after the effective date may receive a new I-94 with a fixed expiration date. That date may affect the student’s timeline moving forward.
Before traveling, students should review their visa stamp, I-20, passport validity, SEVIS record, OPT or STEM OPT status, pending USCIS filings, and possible extension needs.
What used to feel routine may now require more careful planning.
What F1 students should review now
F-1 students should not panic, but they should prepare. Before September 15, 2026, students should review:
- their current I-20;
- their program end date;
- their I-94 record;
- their visa stamp;
- their passport validity;
- OPT or STEM OPT plans;
- school transfer plans;
- change of status plans;
- travel plans;
- any long-term immigration strategy after studying.
Students should also speak with their DSO and, when needed, an immigration attorney before making decisions that could affect status.
The new rule does not end F-1 student visas. But it does reduce flexibility and creates new risks for students who do not track their dates carefully.
Loigica’s takeaway
At Loigica, we see this rule as a major compliance and planning issue for international students.
The end of F1 duration of status means students must pay closer attention to fixed I-94 dates, extension deadlines, grace periods, school transfers, OPT, STEM OPT, travel, and future immigration options.
For many students, the safest step is to review the full timeline before the rule takes effect.
Do not assume that your I-20, your school record, or your prior understanding of F-1 status will be enough under the new system. The margin for error is smaller now.
