For decades, F-1 students were admitted to the U.S. for "Duration of Status" (D/S) — no fixed end date on the I-94. As long as your DSO kept your SEVIS record active, you could finish a degree, start another, and extend your program without ever filing anything with USCIS.

That era is ending. DHS proposed replacing D/S in August 2025, received nearly 22,000 public comments, and adopted almost everything it proposed. 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" — was published in the Federal Register on July 17, 2026 and takes effect 60 days later, around September 15, 2026.

It applies to F (academic students), J (exchange visitors), and I (foreign media) classifications. This guide focuses on F-1 students.

Program extensions also get harder: delays caused by academic probation, suspension, or repeatedly failing to finish coursework are now generally unacceptable reasons to extend. Staying enrolled and in good standing matters more than ever.

The short answer: not much. DHS adopted the core of the August 2025 proposal without retreat. The final rule's changes are targeted clarifications and a handful of genuine softenings:

What DHS declined to do, despite thousands of comments: restore D/S, grandfather current students beyond the transition rules, extend the 4-year cap (even for PhDs), lengthen grace periods, add a grace period after an EOS denial, set adjudication deadlines, or change CPT — including Day 1 CPT, which DHS deemed outside the scope of this rulemaking.

If you're in the U.S. in D/S when the rule takes effect, you keep meaningful protections:

• You keep your current program end date — authorized through the end date on your current I-20, up to a maximum of 4 years from the effective date.
• You keep the old 60-day grace period after completion (transition students only).
• Travel converts your admission. Leave the U.S. and re-enter, and CBP admits you under the new fixed-date regime. Factor this into any travel plans.
• OPT reprieve: if you timely file for post-completion OPT or STEM OPT on or before ~March 18, 2027 (244 days after publication), you only file the Form I-765 — no separate EOS..
• Transition students may be eligible to file an EOS when their authorized period runs out.

There's a lot of misinformation circulating, so let's be precise about what the rule actually says.

The rule does NOT eliminate Day 1 CPT. DHS said this directly, responding to commenters who feared a ban: "These comments misinterpret the rule as the rule does not prohibit or eliminate Day-1 CPT... it does not make substantive changes to CPT." Day 1 CPT programs remain lawful exactly as they are today.

But the rule reshapes the landscape around Day 1 CPT in four ways:

1. The "second master's" pathway is closing. The classic route — OPT after one master's, then a second master's with Day 1 CPT — ends for anyone completing a program after ~September 15, 2026. The realistic next step becomes a doctorate (DBA, Ed.D., Ph.D.), many of which also offer Day 1 CPT. Because the ban is not retroactive, your current program's end date determines which side of the line you're on.
2. CPT must fit inside your fixed admission period. If your program runs past your I-94 date, you need an approved EOS. Timely filing protects you: you can keep studying and continue authorized CPT for up to 240 days while USCIS processes your application.
3. Program extensions get harder. Academic probation and repeated course failures are no longer acceptable reasons to extend — good standing is now a compliance issue, not just an academic one.
4. Timing your enrollment matters. Starting your next program — or completing a transfer — before the effective date means operating under today's simpler SEVIS process, with all degree levels still open.
