Duration of Status (D/S) Changes for F1 Visa: Everything Pakistani Students Need to Know
For more than three decades, F1 students entered the United States under a simple promise: stay as long as you maintain your status. That promise has now changed. The Department of Homeland Security has replaced the old “Duration of Status” model with fixed admission periods, and every Pakistani student planning to study in the US needs to understand what this means before they book a flight.
This guide breaks down the new rule in plain language, regarding Duration of Status (D/S) Changes for F1 Visa — what changed, who it affects, key dates, and the practical steps you need to take to stay compliant.
What Was Duration of Status (D/S)?
Duration of Status allowed F-1 students to remain in the United States for as long as they stayed enrolled full-time and followed their program requirements, without a fixed expiration date stamped on their entry record. Their Form I-94 simply listed “D/S” instead of a specific date, and Study in the States confirms this framework let students pursue their full course of study or post-completion practical training without repeatedly filing for extensions.
That flexibility is gone.
What Changed: The New Fixed Admission Period Rule
On July 17, 2026, DHS published a final rule titled “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.” The rule eliminates D/S entirely for F, J, and I visa holders and replaces it with a specific expiration date tied to your program.
How the Fixed Period Is Calculated
Your new admission period is based on the program length listed on your Form I-20, capped at four years, plus a 30-day window to arrive in the US and another 30-day window to depart after your program ends. According to Study in the States, this fixed period becomes your official Admit Until Date (AUD), and it appears directly on your Form I-94 Arrival/Departure Record.
What About Exchange Visitors and Media Representatives?
J-1 exchange visitors receive the same treatment as F-1 students — a fixed period tied to their program length, capped at four years. I visa holders, who are foreign media representatives, receive a shorter window of up to 240 days per admission, with certain nationals facing additional restrictions.
When Does the Rule Take Effect?
The rule takes effect on September 15, 2026. It was classified as a “major rule” under the Congressional Review Act, which gives Congress a window to review it before it becomes fully binding. Several immigration law firms, including Mintz, have noted the rule carries retroactive impact — meaning students already inside the US under D/S will also transition onto a fixed period once the effective date arrives.
Why This Matters If You’re Already Studying in the US
If you’re a Pakistani student currently enrolled under D/S, you don’t get to keep your old open-ended status indefinitely. DHS has built in a transition period, but the requirements depend on your specific situation.
Students Filing for OPT or STEM OPT
If you are present in the United States 60 days before the rule takes effect, and you filed for post-completion OPT or STEM OPT by March 18, 2027, you generally will not need to file a separate Extension of Stay application, based on guidance from Study in the States.
Students Who Travel Before Filing OPT
If you travel outside the US before filing for OPT or STEM OPT, and you get readmitted under a fixed period of admission, you will need to file both an Extension of Stay application and your OPT application separately.
Students With a Pending Cap-Subject H-1B Petition
If you’re a beneficiary of a timely filed, cap-subject H-1B petition and qualify for a cap-gap extension, you generally won’t need a separate Extension of Stay application. You can typically remain in F-1 status until your H-1B petition is approved or a specified date arrives, whichever comes first.
Why the US Government Made This Change
DHS states the new fixed-period system exists to give immigration officers regular checkpoints for reviewing whether F, J, and I visa holders continue to meet eligibility and compliance requirements. According to Envoy Global, the agency intends this shift to strengthen oversight, reduce fraud, and improve national security screening across nonimmigrant categories.
Beyond the admission period itself, the rule also introduces two additional restrictions that Pakistani students should know about:
- Limits on changing academic programs. Both graduate and undergraduate students face new restrictions on switching programs of study once admitted.
- No second degree at the same level. Students who complete a US degree cannot pursue another degree program at the same academic level afterward.
What Happens If You Need More Time in the US?
Once your fixed admission period is set, you cannot simply continue attending class past your Admit Until Date. If your program legitimately requires more time — a longer thesis, a delayed graduation, or additional coursework — you must file an Extension of Stay (EOS) application directly with US Citizenship and Immigration Services (USCIS).
The EOS Process, Step by Step
1. Confirm Your Admit Until Date
Check your Form I-94 as soon as you enter the US under the new system. Your AUD tells you exactly when your authorized stay ends.
2. Coordinate With Your DSO Early
Talk to your school’s Designated School Official well before your program end date. Program-length calculations and documentation requirements can get complicated, especially for research-heavy or multi-year programs.
3. File Your EOS Application With USCIS
You must submit your extension request directly to USCIS, not to your school or SEVP. Expect to demonstrate continued eligibility for your program.
4. Complete Biometrics
The new process requires biometrics submission as part of the extension review, giving USCIS an additional identity verification checkpoint.
5. Track Processing Times Closely
Filing directly with USCIS means your extension is now subject to standard USCIS processing timelines, which can run longer than the old D/S renewal process ever did. Build in extra buffer time — don’t wait until the last month before your Admit Until Date.
Duration of Status vs. Fixed Admission Period: A Quick Comparison
Understanding the practical difference between the old and new systems makes the stakes clearer.
| Factor | Old System (D/S) | New System (Fixed Period) |
|---|---|---|
| Entry record | “D/S” on Form I-94, no fixed date | Specific Admit Until Date on Form I-94 |
| Maximum stay | Open-ended, tied to enrollment status | Up to 4 years for F-1/J-1; up to 240 days for I visa holders |
| Extra time needed | Continued enrollment sufficed in most cases | Must file Extension of Stay with USCIS |
| Compliance checkpoints | Ongoing, informal | Formal review at each extension filing |
| Biometrics | Not typically required for continued stay | Required as part of EOS applications |
| Program switching | More flexible | Additional restrictions apply |
| Second US degree at same level | Generally permitted | Restricted after completing a US degree |
This table makes one thing obvious: the new system shifts responsibility onto the student to track dates and file paperwork proactively, rather than relying on continuous enrollment alone.
What Happens If You Overstay Your Fixed Admission Period?
Overstaying your Admit Until Date is far more serious under the new rule than it was under D/S. Since your status now has a defined expiration date instead of an open-ended compliance standard, failing to file an Extension of Stay before that date can trigger unlawful presence.
Unlawful presence carries long-term consequences for Pakistani students specifically:
- Future visa applications become harder. Accumulating unlawful presence can lead to multi-year bars on re-entering the United States.
- OPT and STEM OPT eligibility can be affected. A lapse in status disrupts your ability to work legally after graduation.
- Green card and future visa sponsorship gets complicated. Employers sponsoring F-1 graduates for H-1B or other visas will scrutinize any gaps in lawful status.
This is exactly why proactive planning — not last-minute scrambling — matters more under the new rule than it ever did under D/S.
How This Rule Affects Your F1 Visa Interview
Even though the fixed admission period applies after you enter the US, it changes what consular officers expect to see during your F1 visa interview in Pakistan. Officers are increasingly likely to ask direct questions about your program length, your planned graduation date, and your understanding of how long you’re authorized to stay.
Walking into your interview with a clear, confident answer about your program timeline — and proof that your I-20 dates are accurate — signals to the officer that you understand your obligations as a nonimmigrant student. Vague or inconsistent answers about your program length can raise red flags at a time when US immigration authorities are already tightening scrutiny across F, J, and I categories.
Why This Matters More for Pakistani Students Specifically
Pakistani applicants already face longer administrative processing at several US consulates compared to some other regions, and F1 visa slots during peak intake season fill up fast. Layering a hard expiration date and a separate USCIS extension process onto that reality means small planning mistakes now carry bigger consequences.
A missed Extension of Stay filing doesn’t just risk a paperwork delay — it can result in unlawful presence, which affects future US visa eligibility altogether. Employers of F-1 students on OPT or STEM OPT are also being advised to monitor I-94 expiration dates closely, according to Ogletree Deakins, which signals how seriously US employers and universities are treating this shift.
How to Prepare Before You Even Leave Pakistan

Build Buffer Time Into Your Planning
Don’t assume you can extend your stay quickly if your thesis or research runs long. Plan your program length conservatively and talk to your DSO about EOS timing well in advance.
Get Full Visa File Support
Errors on your I-20, mismatched dates, or unclear program timelines can complicate your fixed admission period before you even land in the US. Our visa file guidance service reviews every document for accuracy before you submit anything.
Stay Updated on Post-Departure Requirements
Since the fixed-period rule changes how OPT, STEM OPT, and program extensions work, our pre-departure briefing and post-visa support services now include guidance on tracking your Admit Until Date and filing extensions correctly once you’re already studying in the US.
Frequently Asked Questions
What is the Duration of Status (D/S) rule change? It’s a July 2026 DHS final rule that replaces open-ended D/S admission for F, J, and I visa holders with a fixed expiration date tied to program length, capped at four years for F-1 and J-1 visa holders.
When does the new rule take effect? September 15, 2026, subject to Congressional Review Act procedures that could still affect the timeline.
Does this rule affect students already studying in the US? Yes. The rule has retroactive impact, and students currently under D/S will transition to a fixed admission period, though DHS has outlined specific transition provisions depending on individual circumstances.
What is an Admit Until Date (AUD)? It’s the specific expiration date of your authorized stay in the US, reflected on your Form I-94 once the fixed-period rule applies to you.
What happens if my program runs longer than expected? You need to file an Extension of Stay (EOS) application directly with USCIS before your Admit Until Date expires, along with biometrics and proof of continued eligibility.
Can I still pursue OPT or STEM OPT under the new rule? Yes, but the process now interacts with your fixed admission period. Students who file for OPT or STEM OPT before certain deadlines may avoid filing a separate EOS application, depending on their situation.
Can I switch my degree program after I arrive in the US? The new rule adds restrictions on changing academic programs for both graduate and undergraduate students, so switching programs is more limited than it was under the old system.
