You finished your degree, your Optional Practical Training was approved, and you are working for a U.S. employer who wants to keep you. Under the rules that have governed F-1 students for more than forty years, the clock in your passport did not really tick — your Form I-94 said “D/S,” and as long as you kept studying or working within the terms of your status, no fixed date hung over you. A 2026 rule would change that, but a federal court has put it on hold. The Department of Homeland Security has adopted a rule that replaces “duration of status” with a fixed admission date. If it takes effect, then for the students and recent graduates we most often meet — those on OPT or STEM OPT, and the employers who hire them — the shift is not a technicality. It changes when you fall out of status, when unlawful presence starts, and how far ahead you have to plan.
This article explains where the rule stands, what it would change, and the specific steps that F-1 students, OPT and STEM OPT workers, their employers, and students in more difficult situations should be thinking about now.
First, what has actually happened — and what has not
It is worth being precise here, because a lot of the coverage is not. DHS published a Notice of Proposed Rulemaking on August 28, 2025, proposing to end duration of status for F (academic students), J (exchange visitors), and I (foreign media) nonimmigrants. The public comment period closed on September 29, 2025. DHS then published the final rule on July 17, 2026 (91 FR 44976), with an effective date of September 15, 2026.
The rule is not in effect. On September 14, 2026, one day before the effective date, a federal court in Massachusetts postponed that date nationwide while a challenge to the rule proceeds (Presidents’ Alliance v. DHS, No. 26-cv-13799 (D. Mass.)). As of October 4, 2026, the postponement still stands. The government filed a notice of appeal on September 30, 2026 (First Circuit No. 26-2112), but no request to stay the postponement appears on either docket; the district court held a status conference on October 2, 2026, and the parties’ proposed schedule is due October 9. Until that changes, F-1 students are still admitted for duration of status under the older rule, with 60 days after finishing a program or practical training to prepare to leave or transfer (8 CFR 214.2(f)(5), as in force before the rule). The online eCFR already displays the postponed text as “current,” so do not rely on that version for this point.
The rule’s future is less certain than it was in July. But it is published and complete, and it could take effect quickly if the court’s order is lifted. So everything below describes the final rule: what it will change if and when it takes effect. If you are an F-1 student or you employ one, plan around it rather than wait to be surprised by it.
How duration of status works today
Most nonimmigrants are admitted until a specific date. A visitor gets six months; an H-1B worker gets the dates on the approval notice. Those dates print on the Form I-94 admission record, which is the document that actually controls how long you may stay — not the visa stamp in your passport.
F-1 students have been the exception. Since 1978, students have been admitted for “duration of status,” or D/S. Instead of a date, the I-94 simply reads “D/S.” You maintain status by staying enrolled full-time, keeping your Form I-20 valid, and following the rules — full course load, timely program extensions through your Designated School Official, authorized employment only. There is no annual check-in with the government and no fixed date by which you must act. That flexibility is exactly what has let students move from a bachelor’s to a master’s, change majors, transfer schools, or move into practical training without re-applying for a new period of stay each time.
DHS’s core complaint is that D/S gives immigration officers few built-in moments to verify that a student is still doing what the visa allows, and that a small number of people have used open-ended status to remain in the country far longer than a temporary program should require. The final rule’s fix is to give F-1 status an end date.
The new framework: a fixed period of admission
Under the final rule, once it takes effect, an F-1 student would no longer be admitted for D/S. Instead, you would be admitted for a fixed period: the time needed to complete the program listed on your Form I-20, capped at four years, plus 30 days after your program ends. Your I-94 would carry a real “admit until” date, the same as almost every other nonimmigrant.
If your program runs longer than the authorized period — a common situation for PhD candidates, students who change levels, and anyone whose research or training extends past the original end date — you would have to file an application to extend your stay directly with U.S. Citizenship and Immigration Services on Form I-539, with a fee and biometrics, before your admission period runs out. This is the single biggest structural change: what your DSO used to handle inside SEVIS with a program extension now becomes a formal benefit application to USCIS, with USCIS processing times, USCIS discretion, and the risk of a Request for Evidence or a denial.
The final rule also tightens several related rules that will matter to specific students:
- The grace period shrinks from 60 days to 30 days. After you complete your program or your authorized post-completion practical training, you would have 30 days — not 60 — to depart or to take steps to stay in status, such as filing an extension or a change of status. You may file an extension during those 30 days, but you may not work or train while it is pending. That is half the runway families have counted on, and it is easy to burn through while waiting on a decision. Students already here in D/S status when the rule takes effect keep a 60-day period under the transition rule, described below.
- Transfers and changes of study are restricted. Below the graduate level, an F-1 student generally could not transfer schools or change majors or educational level during the first academic year of a program. At the graduate level, a student could not change educational objective at any point, and could not transfer at any point either. In extenuating circumstances, such as a school closing, SEVP can allow an exception to the transfer limits. DHS kept the option to delay these limits until September 14, 2028.
- You can move up, not sideways or down. Once you finish a program in F-1 status after the rule’s start date, you could begin a new F-1 program only at a higher educational level. A new program at the same or a lower level would not qualify for F-1 status.
- Delays are not a guaranteed extension. A delay in finishing by your I-20 end date — including one caused by academic probation, suspension, or repeatedly not completing coursework — generally would not be an acceptable reason for an extension. That is a meaningful trap for students who hit academic trouble.
The change that matters most: unlawful presence starts on its own
This is the provision practitioners are most worried about, and it is the one to understand even if you skip everything else.
Under current policy, because an F-1 student is admitted for D/S with no date on the I-94, “unlawful presence” — the specific clock that triggers the three- and ten-year bars to re-entry under INA § 212(a)(9)(B) — generally does not begin to run until USCIS or an immigration judge makes a formal finding that you violated your status. In practice, that has given students who slipped out of status a margin: the bars usually were not accruing silently in the background.
The final rule would remove that margin once it takes effect. Once you are admitted to a date-certain, the day after that date passes without an approved extension or change of status, you are an overstay — and unlawful presence begins to accrue automatically, the same way it does for a visitor or a worker who blows past their I-94 date. Reach 180 days of unlawful presence and depart, and you face a three-year bar. Reach one year and depart, and it is a ten-year bar. No one has to catch you first. The date does the work.
There is an important piece of protection built into the system, and it is the reason timing becomes everything: if you file your extension of stay on time, before your admission period expires, you are generally in a period of authorized stay while the application is pending, and unlawful presence does not accrue during that time even if your original I-94 date passes. File late, and you lose that shelter. Under a fixed-date regime, “file early” stops being good advice and becomes the whole ballgame.
OPT and STEM OPT: the group most exposed
Most of the F-1 students we work with, we meet at the end — at graduation, when practical training is approved and an employer wants to bring them on. Post-completion OPT gives up to 12 months of work authorization; the STEM extension adds another 24 months. Helping a graduate move from OPT into STEM OPT, and then into a longer-term work visa or a green card, is bread-and-butter work in our practice. The final rule, if it takes effect, lands directly on this group.
Here is the problem. OPT and STEM OPT are benefits tied to F-1 status, and your work authorization can run past your fixed admission date. Today, D/S stretches to cover your authorized practical training. Under the final rule, your admission would end 30 days after the program end date on your I-20, so post-completion OPT would generally take more than a work permit. You would file the OPT work-permit application (Form I-765) and also either an extension of stay or, after travel abroad, a new admission through CBP (8 CFR 214.2(f)(10)(ii)(D) in the final rule). STEM OPT that would run past your “admit until” date needs that time granted too. Miss the extension, and your status — and the work authorization that depends on it — is in jeopardy even though your EAD card still shows a later date. Students already here when the rule takes effect get a transition break on OPT, described below.
And here is the trap that is easy to miss, because it does not work the way the H-1B world works. When an H-1B worker’s employer files a timely extension, the worker keeps working for up to 240 days while it is pending. The final rule does not give F-1 students an equivalent automatic 240-day work extension for OPT. The automatic extension it does offer while a timely extension of stay is pending covers only on-campus employment, curricular practical training, and severe-economic-hardship employment — not OPT or STEM OPT. And an extension filed during the 30 days after your program ends carries no work authorization at all while it is pending. In plain terms: filing your extension on time protects your status and stops unlawful presence from accruing, but it may not keep your OPT paycheck flowing while USCIS adjudicates. That gap between “still in status” and “still authorized to work” is exactly where people get hurt, and it is the first thing we would screen for.
What employers need to plan for
Most of our student matters actually start with an employer. A company hires a graduate on OPT, wants to keep them, and comes to us to build the bridge — STEM OPT, then an H-1B or another work category, and often a permanent residence strategy after that. If you employ F-1 workers, the final rule, once in effect, would add a new dependency you did not have before.
Under D/S, your OPT and STEM OPT employees carried their own status quietly in the background. Under a fixed-date regime, any of them whose admission period expires mid-employment now depends on a USCIS extension of stay being filed on time and adjudicated — a process with real processing times and real denial risk. The practical steps for employers are straightforward but need to start now: know each F-1 employee’s admission “admit until” date, not just their EAD expiration; calendar the extension-of-stay deadline months ahead; and get the longer-term visa or green-card strategy moving earlier than you used to, because the buffer that D/S provided is gone. The H-1B cap-gap timing and OPT end dates become something to manage deliberately, not assume.
Students in more difficult situations: the enforcement edge
The rule’s automatic-unlawful-presence provision falls hardest on students who are already in a fragile spot, and these are people we do see.
We help students who need to file for asylum, and students who run into trouble and drop out of school. Under the current D/S framework, a student who stopped attending did not necessarily start accruing unlawful presence until there was a formal finding. Under the final rule, once it takes effect, a fixed admission date means the clock can start on its own — and a student who has left school, lost status, and taken no action can accrue the unlawful presence that triggers the reentry bars without ever receiving a notice. For someone with a pending asylum claim, the interaction between a lapsed F-1 admission date and the asylum timeline needs to be thought through carefully, not left to chance.
It is also worth being candid: students who fall out of status are squarely within current immigration-enforcement priorities. That raises the stakes on every one of the timing questions above. If you are a student whose enrollment has lapsed, or who is weighing an asylum filing, this rule is a reason to get advice sooner rather than later — while options like a change of status, reinstatement, or another form of relief are still on the table.
Current students versus incoming students
The rule draws a line between students already here and those admitted after it takes effect. Under its transition rule, a student admitted for D/S who is properly maintaining F-1 status on the day the rule takes effect may stay until the later of the program end date on the Form I-20 or the expiration date on the work permit (EAD), for no more than four years, plus 60 days. The rule’s text sets that outer limit at November 14, 2030, because it was written for a September 15, 2026 start (8 CFR 214.1(m)(1) in the final rule). A student in that group who needs more time, or wants to start a new program, would file an extension of stay with USCIS. There is one break for recent graduates: a transition student who files for post-completion OPT or STEM OPT by March 18, 2027 does not also need an extension of stay for that training period. Students admitted after the rule takes effect enter the fixed-date system from day one. If the court’s order is lifted and the rule takes effect later than planned, watch for DHS to say how these dates apply.
What to do now
Nothing has to be filed under the new rule while it is on hold, but you can get ahead of it. A few things are worth doing whether or not it takes effect.
Know your dates. Find out what your program end date is on your I-20 and understand that, once the rule is effective, a real “admit until” date will govern your stay. If you are on OPT or STEM OPT, know how your EAD dates line up against that admission period — the mismatch is where the risk lives. If you employ F-1 workers, build that same calendar for every one of them.
Do not travel casually once you have an extension or change of status pending. Departing the United States while a Form I-539 change-of-status application is pending is treated as abandoning it, and travel while an extension is pending carries its own risks. Under a system where a single missed date starts the unlawful-presence clock, an ill-timed trip abroad can be expensive.
Above all, file early and get advice before you are up against a deadline. The protection this system offers — no unlawful presence while a timely-filed extension is pending — only works if the application goes in before your admission period ends. The students who will have the hardest time are the ones who wait until something has already gone wrong. If your situation is at all complicated — a program running long, an academic problem, a pending asylum claim, a lapse in enrollment, or an OPT window that will outlast your admission date — that is worth a conversation now, while the options are widest.
We work with students, recent graduates on OPT and STEM OPT, and the employers who hire them across Montana, North Dakota, Wyoming, Utah, Idaho, and Colorado. If the end of duration of status affects you or someone on your team, contact our office and we will help you map the timing before it maps you.
