F-1 Visa Rules in 2026: Duration of Status Changes Explained

Last updated: August 8, 2026

The change F-1 students have been hearing about for years is no longer hypothetical. On July 17, 2026, DHS published a final rule establishing a fixed time period of admission and an extension of stay procedure for academic students, exchange visitors, and representatives of foreign information media. It takes effect September 15, 2026 and eliminates Duration of Status. This guide explains what actually changes, what stays the same, and the concrete steps to take before mid-September.

Key takeaways

• The rule is final, published July 17, 2026, and Duration of Status (D/S) is being eliminated.
• Effective date: September 15, 2026. Until that date, F students continue to be admitted for D/S — nothing changes for anyone before then.
• From the effective date, F students are admitted for a fixed period: the length of the program on Form I-20, not to exceed 4 years, plus up to 30 days before the program start and a departure grace period.
• The grace period is shortened from 60 days to 30 days for students subject to the new framework.
• Students already here on D/S and maintaining status on September 15, 2026 transition automatically to an end date based on their current I-20 or DS-2019, capped at 4 years from the effective date.
• To stay beyond the fixed period, you must file an Extension of Stay (EOS) directly with USCIS, including biometrics — no more automatic continuation under D/S.
• OPT carve-out: D/S students in the U.S. on September 15, 2026 who timely file for post-completion OPT or STEM OPT by March 18, 2027 do not need a separate EOS application. Cap-gap protection for timely filed cap-subject H-1B petitions continues.
• The rule is a "major rule" subject to Congressional Review Act review, so there is still a small chance Congress acts on it. Keep checking official sources.

What "Duration of Status" actually means

Duration of Status, abbreviated D/S, is the way F-1 (and J-1) nonimmigrants have historically been admitted to the United States. Instead of stamping a fixed end date on your Form I-94, U.S. Customs and Border Protection (CBP) marks the admit-until field as "D/S." That means you are allowed to remain in the U.S. as long as you:

• Maintain a full course of study at the school listed on your Form I-20,
• Follow the terms of your F-1 status (work authorization limits, reporting requirements, etc.), and
• Complete authorized post-completion practical training (OPT / STEM OPT) plus a short grace period.

The framework is explained by USCIS and Study in the States. See Study in the States — Students and the Form I-94 and USCIS — Duration of Status (D/S) notation.

What DHS finalized

DHS first proposed replacing D/S in 2020; that version was never finalized. A new Notice of Proposed Rulemaking followed in 2025, and on July 17, 2026 DHS published the final rule, "Establishing a Fixed Time Period of Admission and an Extension of Stay Procedure for Nonimmigrant Academic Students, Exchange Visitors, and Representatives of Foreign Information Media," in the Federal Register. The key facts:

• It is a final rule, not a proposal, and it eliminates D/S for F, J, and I nonimmigrants.
• Its effective date is September 15, 2026. D/S continues to apply to admissions before that date.
• F students will be admitted for the program length on Form I-20, up to a maximum of 4 years, plus a 30-day arrival buffer and a 30-day departure grace period.
• Staying beyond the authorized period requires an Extension of Stay application filed with USCIS, with biometrics.
• The rule includes transition provisions for students and scholars currently admitted for D/S.

Always check the primary source: search "fixed time period of admission" on federalregister.gov and follow updates on studyinthestates.dhs.gov. SEVP is holding a stakeholder webinar on August 31, 2026, and Study in the States and ICE.gov/SEVP content will be updated to reflect the rule on and after September 15, 2026.

Proposed rule vs. final rule vs. guidance vs. court decision

Immigration news often conflates four very different things. Use this cheat sheet:

• Proposed rule (NPRM): DHS's draft, opened for public comment. No legal effect on your status.
• Final rule: Published in the Federal Register with an effective date. This is what changes the law.
• USCIS policy guidance: The USCIS Policy Manual can update how existing rules are applied. Effective from the date USCIS says.
• Court decision: A federal court can block or delay a rule. Read the court's order — not a summary — for what actually applies.

Where this rule sits: it has now moved from proposed to final. It is published, dated, and carries a September 15, 2026 effective date — the second category above, not the first.

Who is affected

Now that the rule is final, it affects:

• New F-1 students entering the U.S. on or after September 15, 2026, who receive a fixed admit-until date,
• Current F-1 students who need to remain beyond their fixed admission period, who must file an Extension of Stay with USCIS,
• OPT and STEM OPT applicants, subject to the March 18, 2027 carve-out described below,
• Students transferring between SEVP-certified schools or changing degree level,
• J exchange visitors and I media representatives, who are covered by the same rule.

Transition for current D/S holders

F and J students and scholars who are properly maintaining status on September 15, 2026 and were previously admitted for D/S are authorized to remain until the program end date on the I-20 or DS-2019 valid on that date, not to exceed four years from the effective date, plus the applicable grace period. In most cases you do not need to have your I-94 corrected to a fixed date right away — but your D/S admission is now subject to that transition end date, so you need to know what it is.

What to check on your documents

Form I-20

• Your program end date in the "Program of Study" section is your controlling academic deadline.
• The DSO signature for travel is generally valid for one year (six months if you are on OPT).
• Your funding and dependent information should match your actual situation.
• Check that your program end date works within the four-year maximum admission period. Longer programs (many PhDs, for example) will need an Extension of Stay before the four years run out.

F-1 visa stamp

The date on your F-1 visa is the last date you may use it to enter the U.S. It does not control how long you can stay. An expired visa is fine while you remain in the U.S. in status.

Form I-94

Retrieve your most recent I-94 at i94.cbp.dhs.gov. Before September 15, 2026, F-1 students should see "D/S" in the admit-until field; if it shows a specific date instead, contact your DSO. On or after September 15, 2026, expect a fixed admission date rather than D/S on any new entry — check it against your I-20 program end date and the four-year cap, and raise any mismatch with your DSO right away. Re-check your I-94 after every trip abroad.

Impact on OPT, STEM OPT, extensions, transfers, and change of degree

• OPT: Up to 12 months of post-completion work authorization, filed with USCIS on Form I-765. Rules remain those in USCIS — OPT for F-1 Students.
• STEM OPT extension: Additional 24 months for eligible STEM degrees, filed with an I-983 training plan and an E-Verify employer. See USCIS — STEM OPT.
• Program extension: Requested through your DSO in SEVIS before your I-20 end date if you need more time for academic reasons.
• Transfer: DSOs at both schools coordinate a SEVIS transfer. You must begin classes at the new school within the required timeframe.
• Change of degree level: A new I-20 is issued when you move from, say, a bachelor's to a master's program.

What the final rule changes for these processes:

• OPT / STEM OPT carve-out: If you were admitted for D/S, are in the U.S. on September 15, 2026, and timely file for post-completion OPT or STEM OPT by March 18, 2027, you do not need to file a separate Extension of Stay application.
• Cap-gap: Students with a timely filed cap-subject H-1B petition remain eligible for the existing cap-gap protection.
• Extensions of stay: Continuing past your fixed admission period generally now requires a direct filing with USCIS, including biometrics, instead of simply continuing under D/S with a DSO-updated I-20.
• Graduate students: The rule imposes stricter limitations on changing programs or majors, so discuss any planned switch with your DSO — and ideally an attorney — before committing to it.

USCIS and SEVP are publishing implementation instructions as the effective date approaches; check uscis.gov and Study in the States for the current filing procedures before you submit anything.

Congressional Review Act status

The rule is classified as a "major rule" under the Congressional Review Act, which means Congress has a review window and could, in principle, act on it. That possibility is real but limited, and DHS has said it will publish an update if Congress changes or blocks the rule. The practical approach: plan as though the rule takes effect on September 15, 2026, while checking studyinthestates.dhs.gov and federalregister.gov for any change.

Practical steps to take now

1. Put September 15, 2026 on your calendar. That is the effective date, and the reference point for every transition provision.
2. Ask your DSO about your specific transition timeline — your I-20 program end date, the resulting fixed admission end date, and whether you will need an Extension of Stay.
3. If you are filing OPT or STEM OPT, note the March 18, 2027 deadline for the no-separate-EOS carve-out and file timely.
4. Verify your documents. Confirm your I-20 end date, visa stamp, and I-94 status.
5. Stay in touch with your DSO. Your DSO is your primary source of accurate school-specific guidance.
6. Track official sources only. USCIS.gov, Study in the States, ICE.gov/SEVP (including the August 31, 2026 stakeholder webinar), and the Federal Register.
7. Save copies of everything. Keep digital copies of your I-20s, I-94s, EADs, and payment receipts.
8. Plan travel carefully. Confirm your I-20 travel signature is valid before leaving the U.S.
9. Consider consulting a licensed immigration attorney if you have a status gap, prior denial, or a complex OPT case.

How AbroadHub can help

The single biggest mistake F-1 students are making now is the opposite of last year's: not realizing the rule is already final and assuming D/S simply continues indefinitely. It does not — it ends September 15, 2026. Verify against USCIS and Study in the States directly, get your transition end date from your DSO, and plan OPT and STEM OPT filings around the March 18, 2027 carve-out. AbroadHub helps with the parts around your studies — OPT-friendly and cap-exempt roles in the Jobs feed, housing near campus, and a community of other international students working through the same transition. Download the app to keep it all in one place.

Conclusion

The rule is final. Duration of Status continues only until September 15, 2026; after that, F students are admitted for a fixed period of up to four years and must file an Extension of Stay with USCIS to remain longer. None of this is retroactive to your current stay, and current students transition on their existing I-20 dates. Confirm your own dates with your DSO, track official sources rather than social media, and get legal advice if your case is complicated.
