For decades, an F-1 student’s I-94 said something reassuring: D/S, duration of status. Stay as long as you are enrolled and following the rules. On September 15, 2026, that ends.
DHS published a final rule on July 17, 2026 replacing duration of status with a fixed admission period and a formal extension-of-stay process for F academic students, J exchange visitors, and I representatives of foreign media.
What the Rule Does
Beginning September 15, most F-1 students, J-1 exchange visitors, and their dependents will be admitted for a fixed period rather than an open-ended one. Instead of D/S, the Form I-94 will carry a specific admit-until date.
Under the rule, admission is granted for the length of the program, capped at four years. Anyone who needs more time must file an extension of stay with USCIS, submit biometrics, and demonstrate continued eligibility.
The Federal Register notice classifies the rule as a major rule subject to congressional review. Analyses from Ogletree, Mintz, and Nixon Peabody describe the same core mechanics, and university international offices, including those at Yale, Columbia, USC, and Pitt, have published guidance for affected students.

Why It Matters More Than It Sounds
Duration of status did more than simplify paperwork. Under D/S, a student who fell out of compliance did not begin accruing unlawful presence until a government finding said so. A fixed date changes that arithmetic. Once the admit-until date passes without an approved extension, the exposure becomes far more mechanical.
Unlawful presence of more than 180 days can trigger a three-year bar on reentry, and more than a year triggers a ten-year bar. That is the real cost of a missed filing deadline under the new structure.
The rule also introduces a filing burden that did not previously exist. Degrees run long for legitimate reasons: a failed course, a research delay, a medical leave, a dissertation that takes five years rather than four. Each of those now requires an application, a fee, biometrics, and processing time measured in months.
Who Is Affected
The rule reaches F-1 academic students and F-2 dependents, J-1 exchange visitors and J-2 dependents, including researchers, professors, and physicians, and I nonimmigrants working as representatives of foreign information media. Universities and designated school officials face new advising and tracking obligations.
Students already in the United States before September 15 should consult their designated school official about how the transition applies to them, because guidance has varied by institution.
What This Means for You
Find your admit-until date on your I-94 at the CBP I-94 website after September 15, and put it on a calendar.
File extensions early. Processing time is the risk, not eligibility, so build in months rather than weeks. Talk to your designated school official or responsible officer before making changes, because changing programs, levels, or schools now interacts with a hard date.
Keep status documents current. Your I-20 or DS-2019, transcripts, and funding evidence all support an extension request. Do not assume enrollment alone protects you, because under the new rule it does not.
Given the August 5 USCIS guidance allowing denials without a Request for Evidence, an extension application filed with incomplete documentation now carries real risk.
