DHS Published the Final D/S Rule on July 17. Duration of Status Ends September 15, and the Final Version Also Restricts School Transfers and Academic Progression.

Why July 17 is different from what came before

In May 2026, when DHS submitted this rule to the White House Office of Management and Budget for pre-publication review, the timeline was speculative. OMB review typically runs 30 to 90 days. The rule could have been modified. A legal challenge before publication could have paused it. None of that happened.

On July 17, 2026, DHS published the final rule in the Federal Register — document 2026-14439. The rule is now binding. It does not require additional notice-and-comment. The effective date is September 15, 2026. That is 52 days from the date this article is being written.

The rule applies to F-1 academic students, J-1 exchange visitors, and I visa holders representing foreign media. All three categories currently use Duration of Status — the framework that allows admission for the length of a compliant program rather than until a specific I-94 date. That framework ends on September 15 for all three. The rule covering D/S that most people in those categories have never thought twice about is going away in eight weeks.

The transition provision — and the travel trap

DHS built transition rules for people currently in D/S status. The specific provision: if you are an F or J nonimmigrant properly maintaining status on September 15, 2026, and you were previously admitted for D/S, you are authorized to remain in the United States until the program end date on your current I-20 or DS-2019, or four years from September 15, 2026 — that is, September 15, 2030 — whichever comes first. You do not need to file a Form I-539 to benefit from this transition.

That sounds workable. The trap is travel. If you leave the United States after September 15, 2026 and return, you lose the transition protection. On reentry, CBP will admit you under the new fixed-period rules — meaning you will receive a specific Admit Until Date on your I-94, not D/S. That date will reflect your current program end date on your I-20 or DS-2019, capped at four years from reentry. If your program is expected to run six years and you reenter in October 2026, your I-94 caps at October 2030 regardless.

The practical effect: students with programs longer than four years, doctoral students in particular, who have international travel planned after September 15 should think carefully before leaving. Reentry after September 15 ends your D/S transition and starts the fixed-period clock from the reentry date. That is not automatically catastrophic — the I-94 still reflects your current program end date up to four years — but it eliminates the transition cushion and can create a gap between your program timeline and your authorized stay.

Academic mobility restrictions the original proposal didn't have

This is the part of the final rule that received the least attention before July 17, in part because the full scope wasn't available in the earlier framing. The final rule imposes restrictions on what the rule calls academic mobility — what F-1 students can and cannot do in terms of school changes, program changes, and degree-level progression.

First: F-1 students must complete their first academic year before transferring to a different school. Under current rules, a student can transfer mid-year with DSO approval through SEVIS. Under the final rule, the student must have completed one full academic year at their current school before a transfer will be recognized. Narrow exceptions approved directly by DHS exist but are not the default path.

Second: graduate students face strict limits on changing educational objectives — meaning their field of study or degree program. Changing majors or program focus at the graduate level requires formal approval and is subject to narrow exceptions. The rule treats the educational objective stated on your I-20 as a fixed element of your authorized program, not something that can be updated freely through your DSO.

Third: students may not pursue another degree at the same educational level or a lower level while remaining in F-1 status. You can go from a bachelor's to a master's. You can go from a master's to a doctorate. What you generally cannot do is pursue a second bachelor's, a second master's in a different field, or a certificate at a level below your existing credentials — not while staying in F-1 status under this rule. DHS acknowledged that implementing these academic mobility restrictions requires significant SEVIS system updates. Because of that, the agency reserved the right to delay implementation of the transfer and educational level provisions until as late as September 14, 2028. The end of D/S itself — the fixed I-94 date — takes effect September 15, 2026 regardless. But the school transfer restrictions and level-change restrictions may not be enforced in SEVIS until 2028.

OPT, STEM OPT, and the March 18 deadline

DHS created a specific carve-out for current D/S students planning to use Optional Practical Training or STEM OPT. The rule: if you are present in the United States on September 15, 2026, and you timely file Form I-765 for post-completion OPT or STEM OPT by March 18, 2027, you do not need to file a separate Extension of Stay for that OPT or STEM OPT period. March 18, 2027 is 244 days from July 17, 2026 — that is the calculation DHS uses.

The carve-out goes away if you travel internationally after September 15, 2026. If you leave and reenter, you'll be readmitted under the new fixed-period rules. In that case, when you eventually file for OPT, you will need to submit both the I-765 for work authorization and an Extension of Stay application if your fixed I-94 date does not cover the period through your OPT end date.

For employers who hire OPT and STEM OPT workers: employees admitted under the new fixed-period rules whose I-94 Admit Until Date expires during their STEM OPT period will need a USCIS-approved Extension of Stay to keep working. USCIS processing times for standalone applications in some categories currently run over fifteen months. An employment authorization gap caused by processing backlogs is not a theoretical scenario — it is what happens when the I-94 expires before USCIS acts on the EOS application. Employers hiring OPT workers should start tracking their employees' I-94 dates alongside the EAD expiration dates, because those are now two distinct deadlines that can diverge.

Grace period and the unlawful presence clock

The final rule cuts the F-1 post-completion grace period from 60 days to 30 days. J-1 exchange visitors already had a 30-day grace period — that stays the same. The 60-day window that F-1 students had to wrap up affairs after completing their program, apply for OPT, or arrange departure is cut in half. For a student who completes in May and had intended to use the summer months to apply for jobs while OPT was pending, 30 days is a meaningful compression.

Under the current D/S system, the unlawful presence rules for F and J students are technically complex. A student who falls out of status in the D/S system does not automatically begin accruing unlawful presence — a formal administrative or judicial finding of a status violation is typically required first. The three-year and ten-year reentry bars triggered by unlawful presence have not applied to D/S students in a straightforward automatic way.

Under the fixed-period framework, that complexity disappears and the rules become stricter. Unlawful presence begins accruing the day after the Admit Until Date on the I-94 if no timely extension, OPT application, or departure has occurred. At 180 days of accumulated unlawful presence, reentry complications arise. At one year, a ten-year bar on reentry applies. The fixed-period framework removes the D/S structural protection that kept students from automatically triggering these bars through program-related status gaps.

What to do in the next eight weeks

If your program end date is more than four years away: the transition provision gives you until your current program end date or September 15, 2030, whichever comes first. No I-539 is needed for the transition period itself. But you need to identify that date now and understand when an EOS will eventually be required. For doctoral students five or six years into a seven-year program, the transition cushion gets you almost to the end — but not quite.

If you plan to travel internationally after September 15: talk to your DSO before you go. Reentry after September 15 puts you under the new fixed-period rules, which may create a gap between your new I-94 date and your actual program completion timeline if your program is longer than four years from your reentry date. Understand the math before you travel.

If you are finishing your program soon and planning OPT: file your I-765 as early as eligible — 90 days before program completion. If you are present in the US on September 15 and file before March 18, 2027, you are inside the carve-out and do not need to file a separate EOS. If you travel internationally and reenter after September 15, that carve-out is gone.

If you are a doctoral student in year two or three: find your current I-20 program end date, confirm it accurately reflects your expected completion, and work with your DSO to ensure it is current. If your expected completion date is beyond September 15, 2030, start understanding now what a USCIS Extension of Stay would require and what processing times look like.
