Duration of Status Ends on 15 September — What Every F-1 Student Should Do in the Next Six Weeks

F-1 Visa New Rules For nearly fifty years, an F-1 student’s Form I-94 said two letters: D/S. Duration of status. It meant that as long as you were enrolled and following the rules, the clock did not run out on you.

On 15 September 2026, those two letters are replaced by a date.

The Department of Homeland Security published the final rule in the Federal Register on 17 July 2026, and it takes effect sixty days later. If you are already in the United States, if you are boarding a flight for the autumn intake, or if you are planning to file for OPT this year, the next six weeks decide which set of rules you live under — possibly for the rest of your time in America.

What are the new F-1 visa rules in 2026?

From 15 September 2026, F-1 students are no longer admitted for “duration of status.” Form I-94 will instead carry a fixed end date: the program end date on your Form I-20, capped at four years, plus a 30-day departure period. Staying beyond that date requires a formal extension of stay from USCIS.

That is the whole change in one paragraph. Everything else is detail — but the detail is where people lose their status.

First, the misunderstanding that is spreading fastest

Headlines have shortened this rule to “international students limited to four years.” Read carefully, that is not what the regulation does.

The four-year cap applies to a single period of admission, not to your total time in the United States. As university international offices including Yale’s have pointed out, a PhD candidate, a medical resident, or a student who finishes a degree and moves on to OPT can still lawfully exceed four years — they simply have to obtain more time through an extension of stay, or by travelling abroad and being readmitted, before the current period expires.

So the rule does not end long degrees. It ends automatic long degrees. Time you used to get by default now has to be applied for, paid for, and approved — and approvals are never guaranteed.

Who is affected, and how — the two groups

Everything depends on where you are on 15 September 2026.

Group 1: You are inside the US on 15 September, in valid status, admitted for D/S

You are in the transition group, and this is the better place to be.

You do not need to rush to Customs and Border Protection for a corrected I-94, and you do not need to file anything just because the rule exists. Your authorised stay runs to the program end date printed on the Form I-20 that is valid on the effective date, capped at four years from 15 September 2026, plus the 60-day departure period F students have always had.

In practice that gives the transition group an outside date of 14 November 2030. J-1 exchange visitors, whose departure period is 30 days, have an outside date of 15 October 2030.

There is one action that ends this protection instantly — see the travel warning below.

Group 2: You are admitted on or after 15 September 2026

You get a dated I-94 from your first entry.

Your situation	What your I-94 will say
Degree program	Program end date on Form I-20, maximum four years, plus 30 days
Program longer than four years	Capped at four years — file an extension of stay or depart and re-enter
Post-completion OPT approved	OPT EAD end date, plus 30 days
STEM OPT approved	STEM OPT EAD end date, plus 30 days
English language training program	Maximum 24 months, plus 30 days
Public high school	12 months in aggregate
F-2 dependants	Cannot extend beyond the principal F-1 student

Note the second change hiding in that table: the F-1 grace period after your program ends drops from 60 days to 30 days. Half the runway to change status, transfer, or leave.

The travel trap nobody is putting in the headline

This is the single most expensive detail in the rule, and it is the reason this article exists.

If you are in the transition group and you leave the United States and return on or after 15 September 2026, Customs and Border Protection will readmit you with a fixed date on your I-94. Your D/S protection is gone, permanently, and you inherit the 30-day grace period instead of 60.

Read that again if you were planning a December trip home.

Nothing in the rule stops you from travelling. But a two-week visit to family in Lahore, Lagos, Dhaka or Delhi over the winter break now has an immigration consequence it did not have last year. If your degree is long, if your program end date is uncertain, or if you expect to change academic level later, that trip should be a deliberate decision rather than an automatic one — and it should be discussed with your Designated School Official (DSO) before you buy the ticket, not after.

If you are arriving for the autumn 2026 intake: get in before 15 September

This is the cleanest piece of advice in the entire rule.

Students who enter the United States before 15 September 2026 are generally still admitted under duration of status, and — provided they are maintaining status on the effective date — fall into the transition group described above.

Most US autumn semesters begin in mid- to late August, and F-1 students may generally be admitted up to 30 days before their program start date. For the vast majority of the incoming class, arriving before the deadline is not a sacrifice; it is the normal calendar. But if you were planning a late arrival, a deferred start, or a delayed visa interview that pushes your entry into late September, understand exactly what you are giving up.

If your visa appointment or travel simply cannot happen before 15 September, you are not doomed. You will be admitted under the new framework with a dated I-94, which is manageable — it just requires you to track dates from day one

If you are on OPT or STEM OPT: circle 18 March 2027

Buried inside the guidance is a deadline that affects the group with the most at stake — students already working in the United States.

DHS has provided limited relief for the transition group: F-1 students who timely file Form I-765 for post-completion OPT or STEM OPT on or before 18 March 2027 do not also have to file a separate extension of stay application. File after that window, or fall outside it, and you may need to file the I-765 and an extension of stay — potentially at the same time.

Two pieces of good news for this group, both confirmed in the rule:

• Cap-gap is untouched. If you are the beneficiary of a properly filed cap-subject H-1B petition requesting a change of status while your OPT is still valid, cap-gap continues to bridge you exactly as before.
• The 180-day automatic extension for STEM OPT filings survives. Filing your STEM OPT extension before your OPT expires still buys you the automatic 180 days of continued work authorisation.

The academic restrictions most coverage skipped

The rule is not only about dates. It also narrows what you can change once you are here.

Undergraduates may not change university, major, or education level during their first academic year, unless the Student and Exchange Visitor Program (SEVP) authorises an exception. DHS gives examples such as a school closure or a natural disaster that stops in-person instruction. After a full academic year, standard approval rules return.

Graduate students face tighter limits still, with changes generally requiring exceptional circumstances authorised by SEVP.

Second degrees at the same level are barred. An F-1 student who completes a program after 15 September 2026 cannot enrol in another F-1 program at the same or a lower academic level. A finished US master’s no longer opens the door to a second US master’s — which, as immigration lawyers have noted, effectively closes the popular “day-one CPT” master’s route for people who already hold one.

That last point deserves emphasis for readers using education as a bridge to employment. If your plan was to stack a second master’s while job-hunting, that plan needs replacing now, not in 2027.

The risk that has actually changed: unlawful presence

Under duration of status, unlawful presence generally did not start accruing unless USCIS or an immigration judge formally found that you had fallen out of status. That safety net is gone.

With a fixed date on your I-94, staying beyond it without a timely filed extension of stay means unlawful presence begins accruing. Under Section 212(a)(9)(B) of the Immigration and Nationality Act, more than 180 days triggers a three-year bar on returning to the United States; more than a year triggers a ten-year bar.

This is why “check your I-94” has stopped being routine advice. From 15 September, your I-94 admit-until date is arguably the most important immigration document you own — more important than the expiry date printed on your visa sticker, which governs entry, not stay.

What this means if your goal is a sponsored job in the US

Most readers of this site are not studying for its own sake. The degree is a route to work.

Three practical consequences:

1. Your sponsorship timeline compresses. With fixed dates and a 30-day grace period instead of 60, the window between graduation and an employer’s H-1B filing is tighter. Start sponsorship conversations earlier in the degree, not in the final semester.
2. Extension processing time is now your risk. USCIS backlogs used to be an employer’s problem. Now a slow extension of stay can sit between you and your own status. Build buffer months into every plan.
3. The “study a bit longer while I look” strategy is closing. Between the same-level degree ban and the tighter change-of-level rules, staying enrolled as a holding pattern is no longer reliably available.

Could the rule still change before 15 September?

Honest answer: possibly, but do not plan around it.

The regulation is classified as a major rule subject to congressional review, and DHS has said it will publish a further Federal Register notice if the review process changes the effective date or terminates the rule. Several university international offices have also noted, in their public guidance, that litigation could affect implementation. Critics quoted in coverage by Forbes and analysts at the Brookings Institution have argued the change will deter global talent and that four years does not match academic reality for many doctoral and research programs.

None of that is a plan. As of today, the effective date stands, and SEVP is running a public stakeholder webinar on 31 August 2026 to walk through implementation. Prepare for the rule as written; adjust if it changes.

Your six-week checklist

• This week: Pull up your current I-94 record and your Form I-20. Write down your program end date.
• Before 15 September: If you are entering for the autumn intake, enter.
• Before 15 September: If you were considering a short trip abroad, reconsider the timing with your DSO.
• 31 August: Watch or read a summary of the SEVP stakeholder webinar.
• Ongoing: Keep your SEVIS record accurate and your DSO informed of any change of address, program length, or funding.
• If you are on OPT or STEM OPT: Diary 18 March 2027 and file your I-765 well before it.
• If you expect your degree to run past your I-20 end date: Ask your DSO about an extension of stay now, and budget for the USCIS filing fee and a biometrics appointment.

Key Takeaways

• Duration of status ends for F-1, J-1 and I visa holders on 15 September 2026; the final rule was published on 17 July 2026.
• New admissions get a fixed I-94 date: program end date, maximum four years, plus a 30-day grace period (down from 60).
• The four-year cap limits one admission period, not your total time studying in the US.
• Students inside the US and in status on 15 September keep D/S under transition rules, with an outside date of 14 November 2030 — until they travel abroad and return.
• Extensions run through USCIS on Form I-539, with a fee, biometrics, and possible interview.
• OPT and STEM OPT filers in the transition group who file Form I-765 by 18 March 2027 avoid a separate extension filing.
• Cap-gap and the 180-day STEM OPT automatic extension are unchanged.
• Completing a program after the effective date bars a second F-1 program at the same or lower level.
• Overstaying a fixed I-94 date now accrues unlawful presence, with 3-year and 10-year bars in play.
