F-1 Visa Hard Deadline: What Students Must Know

DHS ends F-1 duration of status on September 15, 2026. What every international student must know about the 4-year cap, OPT filings, and how to extend.

By Jorbi TeamAugust 4, 2026

For nearly fifty years, the I-94 card in every international student's passport was stamped with two letters: "D/S." Duration of status. It meant you could stay in the United States as long as you were enrolled, following the rules, and maintaining your F-1 status. No expiration date. No countdown. On September 15, 2026, that framework disappears. A final rule published in the Federal Register on July 17 (Docket No. 2026-14439) replaces D/S with a hard four-year admission cap for F-1 students and J-1 exchange visitors. The rule takes effect in six weeks, and the majority of the 1.18 million F and J visa holders currently in the United States don't yet understand what it means for their specific situation.

This post breaks down the mechanics, the deadlines, and exactly what you need to do before September 15.

One important caveat upfront: the rule has been classified as a major rule subject to Congressional Review Act oversight, which means Congress could theoretically delay or overturn it. As of August 4, 2026, no such action has occurred, and the September 15 date remains firm. Prepare as if it is.

What "Duration of Status" Actually Was (and Why Losing It Matters)

The D/S system, in place since 1978, was built on a simple idea: your legal stay in the U.S. should track your academic program, not a fixed calendar date. Your I-94 had no expiration. Your lawful presence lasted as long as your enrollment did. Transfer to a new school? Your DSO (Designated School Official) updated your SEVIS record. Take a medical leave? Same process. The government delegated most oversight to universities through the SEVIS tracking system, and you rarely had to interact directly with USCIS just to maintain status.

September 15 ends that arrangement entirely. The American Immigration Council calls this the biggest structural change to student visas in a generation, and they've earned that characterization. What replaces D/S is a fixed "Admit Until Date" tied to your program end date, capped at four years. Need more time? You petition the federal government for it.

The Four-Year Cap: What Actually Changes on September 15

Starting September 15, F-1 students arriving in the U.S. will receive a specific date on their I-94 (called an "Admit Until Date" or AUD) rather than the D/S notation. That date will be whichever comes first: your program end date as listed on Form I-20, or four years from your program start date. The clock starts at your program start date on Form I-20, not the day you physically enter the country, per Duane Morris's analysis of the rule.

Four mechanical details that matter immediately:

The 30-day pre-arrival grace period (before your program starts) does not count against your four years.
The post-completion grace period has been cut from 60 days to 30 days.
Those 30 post-completion days don't count toward the cap either.
If your program end date precedes your four-year mark, your AUD is set to the earlier date.

If you're currently in the U.S. maintaining valid F-1 status under D/S, you don't need to do anything immediately. Per Ohio State University's Office of International Affairs, current students won't be assigned a new I-94 with a fixed date right away, but will need to apply for an extension of stay if they plan to remain beyond their program end date or November 14, 2030, whichever comes first. That outer date is four years plus sixty days from September 15, 2026.

The travel trap. If you leave the United States on or after September 15, 2026 and re-enter, you will be admitted under the new rules with a fixed end date, full stop. Immigration attorneys who have analyzed this rule closely flag it as one of the most dangerous surprises buried in the entire text. A Thanksgiving trip home, a winter break visit to family, a conference abroad: re-entry through U.S. customs after September 15 converts your status to the new fixed-term system regardless of when you originally arrived. Plan any international travel after that date only after you know exactly what your new AUD will be.

How Extensions Work Under the New System: The I-539

Under D/S, your university's DSO handled most of your status maintenance through SEVIS updates. Under the new system, anyone who needs to stay beyond their AUD must file Form I-539 (Application to Extend/Change Nonimmigrant Status) directly with USCIS, pay a filing fee, and attend a biometrics appointment for fingerprinting and background checks.

The DHS press release frames this as returning oversight from university staff to federal authorities. Critics, including more than 60 higher education associations who submitted formal opposition comments, call it an administratively unworkable burden layered on top of already complex student timelines. Both characterizations hold up.

The I-539 process, step by step:

Request an updated Form I-20 from your DSO recommending the extension in SEVIS.
File Form I-539 with USCIS before your AUD expires.
Pay the filing fee: $420 online or $470 by paper (as of spring 2026; verify against the current USCIS fee schedule before filing).
Attend a biometrics appointment at a USCIS Application Support Center.
Submit evidence of sufficient funding and continued enrollment.
Wait for a USCIS decision, which may include a Request for Evidence or an interview.

That wait is where things get genuinely concerning. Standard I-539 processing for F and J status currently runs 6 to 14 months, per immigration attorneys tracking the USCIS backlog. Premium processing (Form I-907, an additional $2,075) brings the window down to 30 business days after your biometrics are completed, but even that won't feel fast when your AUD is approaching.

Attorneys advising on this specific rule are recommending you file 6 to 8 months before your AUD expires. If you wait until 45 days out (USCIS's own minimum recommendation), you're rolling the dice on a processing queue that was already slow before 1.18 million students started adding extension petitions to it.

The critical protection: if you file before your AUD expires, you're in a period of authorized stay while the application is pending. Your status doesn't lapse during that window. If your AUD passes and you haven't filed, you're out of status, and what follows is a much more complicated reinstatement process. File early.

OPT and STEM OPT: The New Filing Sequence

The rule layers in ways that most students, and most employers, haven't fully processed yet.

Under the old system, graduating F-1 students filed one form with USCIS (Form I-765) to get OPT work authorization. Under the new rule, your admission period ends at the earlier of your program end date, your four-year cap, or the expiration date on your OPT or STEM OPT Employment Authorization Document (EAD). Ogletree Deakins' detailed breakdown of the rule confirms that if your OPT or STEM OPT period extends beyond your four-year cap, you need to file both an I-765 and an I-539, two separate forms moving through two separate processing queues.

For STEM OPT seekers, the full required sequence now looks like this:

Form I-765 — standard 12-month OPT application
Form I-539 — required if your OPT period extends past your four-year cap
Form I-983 — Training Plan submitted with your employer
Form I-765 (again) — 24-month STEM OPT extension application
Form I-539 (again) — required if your STEM OPT extension also runs past your cap

That's up to five federal filings to accomplish what previously required one.

DHS did build in one meaningful reprieve. Students who file their I-765 OPT application on or before March 15, 2027 (six months after the rule's effective date) are temporarily exempt from needing a simultaneous I-539. Per the American Immigration Council's analysis, that reprieve expires on March 18, 2027, after which every OPT and STEM OPT applicant whose work authorization would push past their cap must file both forms.

One catch that trips people up: the reprieve doesn't apply if you travel internationally after September 15 and re-enter the U.S. before filing your I-765. Re-entry makes you subject to the full new rules regardless of timing.

If You're in a PhD or Any Program Longer Than Four Years

The math is simply broken for long-form programs. The Peterson Institute for International Economics makes this plain: doctoral programs average 5.7 years to complete, STEM OPT adds up to three more years of post-degree training, and the four-year cap covers neither. Even the average bachelor's degree takes 4.3 years, meaning most undergraduates will hit the cap before finishing.

A concrete example: a student who started a STEM PhD in September 2022 and is currently in the U.S. under D/S will hit their transition deadline on November 14, 2030. If their dissertation defense is scheduled for spring 2031 (a completely normal STEM PhD timeline), they need to file an I-539 well before November 2030, survive a 6 to 14-month processing period, and receive approval before their status lapses. Students who haven't filed their I-539 before their OPT I-765 goes in may be out of status at the exact moment they try to apply for OPT, which automatically disqualifies them.

The Brookings Institution also flags restrictions that haven't gotten nearly enough attention: undergraduate students can't transfer schools or change majors in their first year, graduate students can't change programs at any point without a formal USCIS petition, and no F-1 student can pursue a second degree at the same or lower level after completing a program.

If you're in year three or four of a PhD program right now, schedule a meeting with an immigration attorney this week. Not next month.

Five Actions to Take Before September 15

NAFSA estimates that Designated School Officials will need roughly 67 hours of rule familiarization in year one alone. Your DSO's office is about to get very busy, very fast. Get in front of the queue now.

Pull your I-94 record at i94.cbp.dhs.gov and confirm your current status notation and any admission date on file. If it still shows D/S, that changes the moment you re-enter after September 15.

Compare your Form I-20 program end date against September 15, 2030. If your program runs past that date, you will need an I-539 extension. Build your filing timeline with your DSO now, not when the deadline is two months out.

Cancel or postpone any international travel after September 15 until you understand your new AUD. Re-entry converts you to the new fixed-term rules immediately. If travel is unavoidable, consult your international student office before you book anything.

If you plan to pursue OPT, get your I-765 filed before March 15, 2027. That deadline qualifies you for the six-month reprieve and spares you from filing both the I-765 and the I-539 simultaneously. Miss it and you're doing both.

If you're a PhD student in year three or four, or in any program that structurally exceeds four years, consult a private immigration attorney in addition to your DSO. Institutional advising will be stretched thin this fall. The stakes are too high to rely on one overburdened office.

On legal challenges: a similar DHS attempt to end D/S in 2018 was blocked in federal court and ultimately withdrawn. Advocates and higher education coalitions have signaled they are preparing legal arguments that this rule is "arbitrary and capricious." As of August 4, 2026, no injunction has been filed, and no court has paused the September 15 effective date. Keep monitoring for updates, and prepare for the rule to take effect exactly as scheduled.

Frequently Asked Questions

Does the four-year cap apply to students already in the United States?

Yes, but with a transition period. If you're currently in the U.S. under F-1 D/S status, you won't be immediately assigned a new I-94 with a fixed date. Per Ohio State's OIA guidance, you will need to file for an extension of stay with USCIS if you plan to remain beyond your program end date or November 14, 2030, whichever comes first. If you travel internationally after September 15 and re-enter the U.S., you will be subject to the new fixed-term rules from that point forward, full stop.

What does filing Form I-539 actually cost?

Filing online costs $420; filing by paper costs $470. Biometrics are included in those fees as of recent USCIS schedules. If you want faster processing (30 business days rather than 6 to 14 months), premium processing through Form I-907 costs an additional $2,075. Verify current amounts against the live USCIS fee schedule before filing, since USCIS adjusts fees periodically.

If I'm applying for OPT after graduation, do I also need to file an I-539?

It depends on timing. If you file your I-765 OPT application on or before March 15, 2027, you qualify for the six-month reprieve and don't need to file an I-539 simultaneously. After March 18, 2027, all OPT applicants whose OPT period would extend past their four-year cap must file both forms. Per NPR's reporting on the rule, fall 2026 enrollees are already covered by the new framework from the moment they arrive.

Can I lose my F-1 status while my I-539 is pending?

No, as long as you file before your AUD expires. Students who submit an I-539 before their admission period ends are in a period of authorized stay while USCIS processes the application. If your AUD passes and you haven't filed, you're out of status, which triggers a much more complicated reinstatement process. File early, and file with time to spare.

What happens if Congress uses the Congressional Review Act to block the rule?

If Congress acts, DHS is required to publish a notice in the Federal Register announcing a new effective date or terminating the rule entirely. As of August 4, 2026, no such action has occurred. Monitor the Federal Register and your university's international student office for updates between now and September 15, but plan your timeline around the rule taking effect as written.
