- International students currently maintain lawful status through the flexible Duration of Status (D/S) system.
- Graduates benefit from a 60-day grace period to depart, transfer, or change their immigration status.
- A 2025 proposal could replace D/S with fixed dates and reduce the grace period to 30 days.
(UNITED STATES) International students on F-1 visas are still governed by the long-standing duration of status (D/S) system, which lets them remain in the United States as long as they keep full-time student status and follow the rules. They also get a 60-day grace period after finishing a program or authorized training, giving them time to leave, change status, or move to another school.
That framework remains in place for now. A Department of Homeland Security proposal released in August 2025 would replace D/S with fixed admission periods, cut the grace period to 30 days, and tighten extension rules, but the plan is still only proposed as of March 2026.
Current rules keep stay tied to student status
Under today’s system, an F-1 student’s I-94 does not carry a fixed end date for lawful stay. Instead, the stay lasts so long as the student keeps valid status. The school’s Designated School Official records the program end date on Form I-20, but the student can remain beyond that date if the academic work continues and the school approves it.
This is why D/S matters so much. It gives students room to finish research, respond to academic delays, or shift course loads without filing for a USCIS extension every time the calendar changes. For many students, that flexibility is the difference between staying on track and falling out of status.
To keep that protection, students must stay enrolled full-time, make normal academic progress, and report required changes to the school. Address updates must go to the DSO within 10 days. Drops below full-time without approval, unauthorized breaks, or unreported changes can end lawful stay and trigger unlawful presence.
The post-program grace period still gives students breathing room
After a program ends, or after post-completion Optional Practical Training or STEM OPT ends, F-1 students receive a 60-day grace period. During that time, they may depart the country, transfer to another school, begin a new program, or change status, such as to H-1B.
That window does not allow work unless the student has separate authorization. It is a transition period, not an employment benefit. Once it ends, remaining in the country without another valid status creates unlawful presence the next day.
For a student who finishes a bachelor’s degree in May, the grace period usually runs into July. That extra time often matters for graduation paperwork, job searches, and visa planning. The official USCIS page on F-1 students and employment authorization remains the clearest federal reference for status rules and work categories.
OPT and STEM OPT extend time through work
Optional Practical Training gives F-1 students up to 12 months of work in their field. STEM OPT adds 24 more months for qualifying science, technology, engineering, and math degrees. Both depend on school recommendation and USCIS approval through an Employment Authorization Document.
The rules are strict. Standard OPT is generally available once per degree level. STEM OPT requires an E-Verify employer and a training plan. Students must also report employment changes to the DSO within 10 days.
If the EAD expires, the 60-day grace period starts at the end of OPT or STEM OPT. VisaVerge.com reports that students and employers continue to treat this window as one of the most closely watched parts of the F-1 system because job timing often determines whether a graduate can stay in the country.
Travel, visas, and reentry are not the same as status
Many students confuse visa expiration with status expiration. They are different. The visa stamp in the passport is only for entry into the United States. The D/S notation on the I-94 controls lawful stay inside the country.
That means an expired visa does not end student status. It only affects reentry after travel abroad. A student who leaves the country with an expired visa must renew it before returning.
Travel timing still matters. Students should return before the I-20 program end date, avoid risky trips while OPT is pending, and confirm their documents with the DSO before leaving. Reentry after the grace period or after status has ended can lead to denial at the border.
The proposed DHS rule would change the system sharply
DHS published a proposal in August 2025 that would rewrite the F-1 system. The biggest shift would end D/S and replace it with fixed admission periods of up to 4 years, or 24 months for language training. Students who need more time would have to file for extensions with USCIS.
The plan would also cut the grace period from 60 days to 30 days, impose tighter limits on program changes, and require more documentation for extensions. Under the proposal, some extensions would be allowed only for academic necessity, illness, or exceptional circumstances.
Graduate students would face tighter movement between programs. First-year students would face school-lock-in rules. The plan also contemplates biometrics and more financial proof for extension requests. Public comments closed on September 29, 2025, but the rule has not been finalized.
What current students are watching most closely
Current F-1 students remain under D/S until any new rule takes effect. That is the practical reality for now. Students already in the country would not suddenly lose status simply because the proposal exists.
Still, the direction of travel is clear. Long programs, especially doctoral research, would be hardest hit if fixed stay limits become law. Students in those programs often depend on D/S because timelines shift with labs, dissertations, and fieldwork.
The proposed transition would let current students stay until the end date on their I-20 or four years from the rule’s effective date, whichever comes first. Timely OPT and STEM OPT filings would still preserve stay through EAD plus the grace period.
Work limits still shape daily student life
F-1 rules also limit employment during study. On-campus work is capped at 20 hours a week during the term and may be full-time during breaks. Off-campus work generally must fit CPT, severe economic hardship rules, or OPT and STEM OPT.
These limits matter because many students rely on lawful work to pay rent, build experience, or support families. A misstep can end status quickly. Unauthorized work, excess unemployment during OPT, or dropping below full-time enrollment without approval all carry serious consequences.
What the current framework means in practice
For now, the main rule is simple: stay enrolled, keep your I-20 current, and respect the grace period. The current system still gives students room to finish studies, apply for OPT, and move into work or a new degree without a fixed visa clock cutting them off.
A student who keeps full-time status and follows school reporting rules can remain in the United States through the full academic program and authorized training. A student who loses status, by contrast, can begin accruing unlawful presence quickly, with possible 3-year or 10-year reentry bars.
That contrast is why the debate over D/S has drawn such attention. Supporters of the current model value flexibility. Critics of change want tighter control. For international students, the stakes are immediate: the length of lawful stay, the timing of work, and the ability to plan a future in the United States all depend on how F-1 visas are treated next.
