Duration of Status Is Ending on 15 September 2026: The Fixed Clock Every F-1 Student Now Lives On

By Team Maven  |  Published 4 September 2026  |  16 minute read

On 15 September 2026, the rule that has governed how long an international student may stay in the United States since 1978 stops applying. Duration of status is ending, and F-1 students admitted from that date will carry a fixed expiry date on their I-94 instead of an open-ended permission tied to being enrolled. If you are already in America, most of you do not have to do anything this month. If you are flying out for Fall 2027, this changes the shape of your entire degree.

For nearly fifty years, an F-1 student was admitted for “D/S” — duration of status. It meant your permission to remain lasted as long as you were doing what your visa said you would do: enrolled full time, making progress, following the employment rules. There was no date to watch. You could take an extra semester, switch from a master’s to a PhD, or add a STEM OPT extension, and your legal stay simply stretched to accommodate it.

That framework is gone. The Department of Homeland Security published the final rule ending duration of status on 17 July 2026, at 91 FR 44976, under DHS Docket No. ICEB-2025-0001. It takes effect on 15 September 2026. From that date, an F-1 student is admitted for the length of the programme shown on the Form I-20, capped at four years, plus thirty days to leave the country. When that date passes, the permission ends — whether or not you are still enrolled, still writing your thesis, or still waiting on a decision from a university committee.

India has more at stake in this than any other country. Open Doors 2025 counted 363,019 Indian students in the United States in 2024/25, roughly 31 per cent of all international students there. This rule lands on that population first.

Duration of Status Ending for F-1 Students: What Actually Changes on 15 September

Strip away the noise and the change is one sentence long. Your right to be in the United States used to be a condition. It is now a date.

Under duration of status, the “Admit Until Date” on your Form I-94 read D/S. There was nothing to expire. If you fell out of compliance, a school official or an immigration officer had to make a formal finding before your stay became unlawful, and there were procedures around that finding.

From 15 September 2026, the I-94 carries an actual date. Customs and Border Protection sets it when you enter. USCIS sets it when it approves an extension or a change of status. After that date passes, you are out of status automatically. No finding, no notice, no letter. The calendar does it.

The Four-Year Number Is a Ceiling, Not an Allowance

This is where almost every reel, WhatsApp forward and YouTube thumbnail has misled people over the last six weeks, and it is worth being precise about because the mistake runs in the wrong direction. Students are hearing “four years” and feeling reassured. Most of them are not getting four years.

The rule admits an F-1 student for the length of the programme listed on the Form I-20, not to exceed four years, plus a thirty-day departure period. The four years is an upper limit that only bites on long programmes. A two-year master’s gets roughly two years. A one-year master’s gets roughly one.

Read the PhD row and the bachelor’s row together and you can see who this rule was actually written for. It was not written to stop two-year master’s students. It was written to put a federal checkpoint in the middle of every long degree, and it catches everyone else on the way past.

The Date That Now Runs Your Life, and Why Your Visa Stamp Is Not It

Three documents, three different jobs, and confusing them is the most common way an otherwise careful student falls out of status.

• The visa stamp in your passport is permission to travel to a US port of entry and ask to be let in. Nothing else. It can expire while you are lawfully inside the country and that is completely normal.
• The Form I-20 is your school’s document. It records your programme, your funding and your programme end date. It is not a permission to stay.
• The Form I-94 is the record of your admission, and from 15 September 2026 its Admit Until Date is the date your lawful stay ends. This is now the single most important date in your American life.

Retrieve your I-94 from the CBP I-94 website after every single entry into the United States, print it, and check the date against your I-20. Officers make data-entry errors, and under duration of status a wrong entry was usually harmless because the field said D/S. Under a fixed date, a typo is the difference between lawful presence and an overstay you did not know you were accruing. If the date is wrong, take it to your international student office in the same week, not the same semester.

If You Are Already in America: The Transition Rule and the 14 November 2030 Outer Date

If you were admitted for duration of status before 15 September 2026, you are not thrown onto a fixed date overnight. DHS built a transition provision, and for most current Indian students it is generous. The official DHS FAQ on the final rule sets it out in full.

You may remain under your existing D/S admission until the earliest of: the programme end date on your Form I-20, the end date of your post-completion OPT, or the end date of your STEM OPT — and in no case beyond 14 November 2030, which is four years from the effective date plus a sixty-day departure period. You keep the sixty-day grace period, not the new thirty-day one. You do not need a corrected I-94 and you do not need to file anything.

That does not mean nobody should travel. It means travel becomes a decision with an immigration consequence attached, and it should be taken with your international student office rather than around them. For a student finishing in 2027 or 2028, converting to a fixed date is often harmless, because the fixed date will simply mirror your programme end date. For a PhD student in year two, or anyone whose completion date is genuinely uncertain, converting early costs you the cushion the transition rule was designed to give you.

Extension of Stay: Form I-539, What It Costs, and What USCIS Will Accept

If you need more time than your Admit Until Date allows, you file Form I-539, Application to Extend or Change Nonimmigrant Status, with USCIS. This is the single largest new burden the end of duration of status creates, and it is worth understanding before you need it rather than during the week you need it.

What counts as a good reason, and what does not

DHS did not leave the standard open. An extension may be approved for a compelling academic reason, a documented medical illness, or circumstances genuinely beyond the student’s control. The rule then names what will not work, and the language is blunt: a delay in completing the programme by the end date on the I-20, “including but not limited to delays caused by academic probation or suspension or a student’s repeated inability or unwillingness to complete his or her course of study,” is generally an unacceptable reason.

Translate that into the situations that actually occur. A supervisor leaving mid-thesis, a laboratory closure, a documented hospitalisation, a visa-related delay in returning from a family emergency — these are the shape of a fundable case, and each of them needs paperwork created at the time it happens, not reconstructed a year later. Two backlogs and a repeated semester are not. That is a new and permanent reason to take academic performance seriously in the first year, and it is the part of this rule Indian students most consistently underestimate.

What Happens to OPT and STEM OPT, and the 18 March 2027 Deadline

OPT survives. The rule does not shorten it, does not remove the twenty-four month STEM extension, and does not touch the cap-gap provision that carries a graduate from an expiring OPT into an H-1B start date. What it changes is the paperwork around it, and there is a dated window that current students should not miss.

The transition window. A student admitted for duration of status before 15 September 2026 who files Form I-765 for post-completion OPT or for the STEM OPT extension on or before 18 March 2027 — six months after the effective date — does not need to file a separate extension of stay. That is a real saving of a fee, a biometrics appointment and an unknown processing wait. It is forfeited if you travel abroad and re-enter on or after 15 September 2026, because you are no longer a D/S student when you come back.

After that window, and for everyone admitted under the new rule. An OPT application generally means two filings, not one: Form I-765 for the work authorisation and Form I-539 to extend the admission period to cover it. When it is approved, your authorised stay runs to the end date on your EAD plus thirty days.

The money is not the problem. The queue is. Every one of those filings is a decision you are waiting on, made by an agency that has published no processing time for student extensions at this volume, and each one is a point at which a request for evidence can arrive in your final semester.

The Quiet Clauses: Transfers, Level Changes and the Second Master’s That Just Closed

The headlines have been about four years. The provisions that will affect more Indian students in practice sit further down the rule and have barely been reported here.

• Undergraduates cannot transfer schools before completing the first academic year at the school that admitted them, absent an SEVP exception. The community-college-then-transfer route that a lot of families budget around now has a fixed floor under it.
• Graduate students cannot change their educational objective at any point in the programme, and cannot transfer schools during it, except in defined extenuating circumstances. Arriving for an MS in Computer Science and moving to Data Science after a semester is no longer an internal university matter.
• Progression is upward only. A student who has completed a degree at one level cannot then pursue the same or a lower level. A second master’s in the United States after a first one, an option a large number of Indian students have used to reset their OPT clock or change field, is closed off.
• English language training is capped at twenty-four months in aggregate, breaks and vacations included, across all enrolments.

If your plan involved starting somewhere affordable and moving up, or arriving undecided and choosing a specialisation once you had seen the department, that plan needs rebuilding before you apply. Under the new rule, the programme and the school you name on your first I-20 are close to final. Choose them as if they are.

Unlawful Presence: The Risk That Genuinely Changed

Everything above is administrative. This part is not, and it is the reason to take the rest seriously.

Unlawful presence is the count of days a person remains in the United States after their authorised stay ends. Accrue more than 180 days and depart, and you face a three-year bar on returning. Accrue a year or more, and the bar is ten years. Those bars are statutory and they apply to any future US visa, including a work visa, a business visa or a tourist visa fifteen years later.

Under duration of status this was, for most students, a remote risk. Because there was no end date on the I-94, unlawful presence generally began only when USCIS or an immigration judge formally found a status violation. A student who made a mistake usually had a chance to discover it and fix it.

With a fixed Admit Until Date, the count starts by itself on the day after that date. Nobody tells you. A student who misreads the I-94, whose extension is filed a week late, or who assumes the new I-20 from their department extended their stay, can be six months into a three-year bar before anyone notices. That is the single change in this rule with consequences that outlast the degree by a decade.

A Worked Example: A Two-Year Master’s Starting Fall 2027

Take a student flying to the United States for a two-year MS beginning 23 August 2027, with a programme end date of 15 May 2029 on the I-20. Every date below follows from the rule as it currently stands.

Notice what the example does not contain: a crisis. A student who finishes on time, files early and checks the I-94 goes through this without a single emergency. The end of duration of status does not make a well-run degree impossible. It removes the margin for a badly run one, and it converts every academic slip into a federal application.

Notice also what sits at the end of it. Those four lottery attempts run straight into the H-1B system as it now works, which we covered separately in our piece on the proposed $103,265 cap-subject H-1B fee and the wage-weighted lottery. The admission clock and the sponsorship arithmetic are the same decision viewed from two ends.

One Thing That Could Still Change All of This: The Lawsuit

On 18 August 2026 a coalition filed suit in the United States District Court for the District of Massachusetts seeking to stop the rule before it takes effect. The plaintiffs include NAFSA: Association of International Educators, the Presidents’ Alliance on Higher Education and Immigration, the Association of Independent Colleges and Universities in Massachusetts, the American Federation of Teachers, the United Auto Workers and the NewsGuild-CWA. The case is before Judge F. Dennis Saylor IV.

The claims are made under the Administrative Procedure Act: that DHS failed to assess the rule’s costs and benefits adequately, did not meaningfully respond to public comments, did not consider less burdensome alternatives, allowed an inadequate comment period, and exceeded its statutory authority. DHS itself put the annualised cost of the rule at roughly $443 to $449 million.

A motion for a preliminary injunction was heard on 3 September 2026, twelve days before the rule is due to take effect. As this article goes live no decision has been published. There are three possible outcomes and it is worth holding all three: the rule is blocked before 15 September and nothing below changes for now; it is allowed to take effect while the case continues; or it takes effect and is set aside later, which would leave a cohort of students who were admitted under it in an unclear position. The Presidents’ Alliance litigation tracker is the fastest public source for what the court actually does.

What to Do Now, by Situation

If you are already in the United States on an F-1

1. Do nothing hasty. Your duration of status admission continues until your programme, OPT or STEM OPT end date, and not past 14 November 2030.
2. Do not travel internationally between now and the end of your programme without speaking to your international student office first. One re-entry converts you to a fixed date and cuts your grace period from sixty days to thirty.
3. If you will apply for OPT or the STEM OPT extension anyway, look hard at whether you can file the Form I-765 on or before 18 March 2027. Filing inside that window avoids a separate extension of stay entirely.
4. If your graduation date is likely to slip, tell your department this semester and get the documentation created now. A compelling academic reason recorded in real time is a different application from one reconstructed afterwards.

If you are flying out for Spring or Fall 2027

1. Make sure the programme end date on your I-20 is realistic before you accept it. It is now the date your legal stay is built on, not an estimate.
2. Download your I-94 on the day you land and check the Admit Until Date against your I-20. Repeat after every entry.
3. Budget for the new filings — roughly $890 for OPT and again for STEM OPT — as part of your cost of attendance, not as a surprise in your final semester. Our Fall 2027 pre-departure checklist sets out the rest of the six-month runway.
4. Choose your programme and your university as final choices. Graduate-level transfers and changes of educational objective are now restricted, and a second master’s at the same level is not an available fallback.

If you are still deciding on a country for 2027

1. Do not let duration of status ending alone decide it. A well-run two-year master’s finished on time is barely touched by it.
2. Do let it change how you weigh a long or uncertain programme. A PhD, a five-year track, or a course with a high repeat rate now carries an administrative cost that did not exist before.
3. Compare honestly against the routes where post-study permission is granted rather than applied for — the UK Graduate Route, Canada’s PGWP, Germany’s eighteen-month job-seeker permission and Ireland’s Stamp 1G — and price the difference in certainty, not only in fees. We have run that arithmetic in USA vs Canada for Indian students and in UK vs Ireland for Indian students.

Frequently Asked Questions About Duration of Status Ending

The Bottom Line on Duration of Status Ending

Duration of status ending for F-1 students is not the catastrophe it has been sold as, and it is not the non-event that a few reassuring posts have made it out to be. It is a structural change in who controls the clock. For fifty years, a student and their university managed the length of a degree between them. From 15 September 2026, USCIS does, one application at a time.

For a student who finishes a two-year master’s on schedule, downloads the I-94 after every entry, and files OPT on time, the practical effect this decade is a couple of extra forms and about $890 in fees. For a PhD student, a student who repeats a year, a student who wanted to transfer, or a student who assumed a second master’s was available as a fallback, this rule removes options that were quietly load-bearing in a lot of plans.

And for everyone, the risk profile has shifted in a way that is worth stating plainly one more time. Under duration of status, a mistake was usually recoverable. Under a fixed date, an unnoticed overstay of 180 days is a three-year bar on returning to the United States for anything at all. The four minutes it takes to read your I-94 is now the highest-return administrative habit in international education.
