US Student Visa 2026: The End of Duration of Status (D/S)
4/22/2026
As of April 2026, the US Department of Homeland Security (DHS) has implemented one of the most significant structural changes to the F-1 visa in decades. If you are planning to study in the US this year, you are no longer entering with an open-ended timeline; you are entering with a "hard" expiration date.
The Death of D/S: What is a "Fixed Term"?
Previously, your I-94 (arrival record) was marked with "D/S." In 2026, this has been replaced by a specific "Admit Until" date.
The 4-Year Cap: Most students are now admitted for a fixed period of four years or the length of their program, whichever is shorter.
The Extension Hurdle: If your PhD or specialized STEM degree takes longer than 4 years, you can no longer just get an I-20 extension from your school's DSO. You must now file a formal Extension of Stay (EOS) with USCIS, pay a fee, and undergo biometrics.
The 30-Day "Exit Grace Period."
This is the change causing the most anxiety in 2026. The traditional 60-day window to pack up or change status has been slashed.
The New Timeline: Once you complete your program or your OPT ends, you now have only 30 days to depart the United States.
No More "Wait and See": In the past, students often waited until day 45 or 50 of their grace period to apply for a new program or a different visa. In 2026, if you haven't filed your paperwork by Day 30, your SEVIS record is automatically terminated, and you are considered "out of status."
The "24-Month Aggregate" for English Language Training
For students starting with English as a Second Language (ESL) programs before their degree:
The Hard Limit: You are now restricted to a maximum of 24 months of English language study in total.
The 2026 Logic: The government is targeting "perpetual students" who use language schools to stay in the US without progressing to a degree. If you hit the 24-month mark without matriculating into a degree program, your stay cannot be extended.
Restricted Flexibility: No More "Easy" Transfers
The 2026 rules have placed "compliance locks" on program changes.
First-Year Lock: Undergraduate students are now largely prohibited from changing their major or transferring to a new school during their first year of study.
Graduate Level Freeze: Master’s and PhD students face even stricter scrutiny when trying to change "educational objectives" (moving from a Master's in Math to a Master's in Data Science, for example).

Why the Change? The 2026 "Integrity" Push
The US government argues that these changes are necessary to improve national security and oversight. By forcing students to reapply for extensions every few years, they can conduct updated background checks and social media vetting that wasn't possible under the old D/S system.
Conclusion
The transition to Fixed-Period Admission in April 2026 marks a shift toward a more transactional, highly monitored immigration system. While the "Duration of Status" model offered flexibility, the 2026 model demands extreme administrative proactiveness.
Students can no longer rely on their university's DSO to "fix" status issues after the fact. In this new era, your legal stay is tied to a calendar date, not just a classroom seat. To succeed, you must plan your graduation, OPT application, and potential departure with 30-day precision.
