DHS Ends "Duration of Status" for F-1 Students — What Changes Before September 15

What DHS just changed

On July 17, 2026, DHS published a final rule ending “Duration of Status” (D/S) admission for F (academic student), J (exchange visitor), and I (foreign media representative) nonimmigrants. Under D/S, an F-1 student’s I-94 carried no fixed expiration date, and status continued automatically as long as the student stayed actively enrolled and made normal academic progress. That framework has governed F-1 admission for decades, and it ends on September 15, 2026.

In its place, F-1 students will be admitted for a fixed period: up to the length of the program listed on Form I-20, capped at four years, plus 30 days to arrive before the program starts and a 30-day grace period afterward, half the 60-day window D/S students have relied on. Most I visa holders, foreign media representatives, get an even tighter cap of 240 days total.

The Extension of Stay process replaces automatic continuation

Under D/S, a student who needed more time, to finish a longer thesis, start a new program, or begin practical training, generally didn’t need USCIS’s permission. Status just continued on its own. Under the fixed-period framework, anyone who needs time beyond their admitted period has to affirmatively request it, by timely filing Form I-539, “Application to Extend/Change Nonimmigrant Status,” before the admitted period (the “Admit Until Date”) expires, including before the 30-day departure grace period even begins.

A student who files an Extension of Stay application before the deadline can continue on-campus employment, off-campus employment tied to severe economic hardship, and Curricular Practical Training for up to 240 days while the application is pending. A student who misses the filing window has no such bridge. In practice, that means “I’ll deal with it later” is no longer viable for anyone approaching the end of their admitted period. The filing has to happen before the clock runs out, not after.

New restrictions on changing programs

The rule also narrows a student’s ability to switch programs, majors, or degree levels mid-course. First-year undergraduates are barred from changing programs, majors, or education levels within their first year, absent an SEVP-approved exception for extenuating circumstances. Graduate students are barred from changing programs, majors, or educational levels entirely, though transfers may still be permitted where extenuating circumstances apply. For a student who previously used a program change as a way to buy time while sorting out next steps, that option is now largely closed.

The OPT transition window

DHS built in a narrow bridge for students currently on a D/S-based I-94, detailed in the agency’s own Quick Facts summary. A student in that position who timely files Form I-765 for post-completion OPT or STEM OPT on or before March 18, 2027 does not need to separately file a Form I-539 Extension of Stay for that OPT period, because the I-765 filing itself carries the necessary status extension. Students filing after that date, or whose I-94 already reflects a fixed admission period, must go through the formal Extension of Stay process to cover OPT time. March 18, 2027 is a hard transition marker for the OPT and STEM OPT filing mechanic specifically, not a general grace period that applies to every deadline under the new rule.

Why this matters for the O-1A and EB-1A transition

None of this changes O-1A or EB-1A eligibility, but it does change the runway. A student building a record toward a self-petitioned EB-1A or an employer- or agent-filed O-1A used to have the practical cushion of D/S while assembling evidence, securing expert letters, and timing the filing. A fixed admission date removes that cushion: the window to file, get approved, or file a timely Extension of Stay while a petition is pending is now bounded by a specific date on the I-94, not by continued enrollment.

This raises the stakes on exactly the sequencing question our F-1 to O-1A and F-1 to EB-1A pathway guides address: knowing well in advance of the admitted period’s end date whether the record supports O-1A, EB-1A, or both, and building the filing timeline backward from that date rather than backward from graduation. A graduate student who previously might have used a program change to extend a runway while a petition was assembled now needs to plan around a bar on that option entirely.

What stays the same

The underlying academic-progress requirements for F-1 status are unchanged, and the rule does not affect CPT authorized during an active program in the ordinary course. It also does not change O-1A or EB-1A’s substantive eligibility standards in any way; a strong record still qualifies under the same criteria it did before September 15, 2026. What changes is the margin for error: a status framework that used to run on program completion now runs on a calendar date, and an extension process that used to be automatic now has to be filed for, on time, every time.
