The Duration of Status Rule Ends Tuesday. Here’s What Changes

On 15 September the United States replaces “duration of status” with a fixed admission period for international students and exchange visitors. The duration of status rule has governed F and J visas for decades, and its removal is the largest structural change to the American student visa system in roughly fifty years.

The change comes from a Department of Homeland Security final rule published in the Federal Register on 17 July 2026.

What duration of status meant, and what replaces it

Under the old system, F and J holders were admitted for “D/S” — no fixed end date. As long as you were making normal progress in your programme or on authorised training, you remained in status. A PhD that ran seven years raised no immigration question.

From 15 September, new applicants are admitted for the length of their programme or four years, whichever is shorter, plus a 30-day departure grace period — reduced from 60 days for F visas.

Anyone needing longer must file an Extension of Stay with USCIS and demonstrate a compelling reason. A pending application carries an automatic 240-day extension.

The rules that will catch people out

Three provisions in the rule have less to do with time limits and more to do with academic freedom of movement:

• Upward moves only. A student finishing at one level may go on to a higher degree — not a lateral move, not a lower one.
• Graduate students cannot change educational objective at all. The rule defines that as educational level or major. Not in year one, not later.
• Undergraduates cannot change in their first year, absent specific extenuating circumstances.

Dependents fall under the same fixed-term structure and extension requirements as the primary visa holder.

If you are already in the US, read this part twice

Students and scholars physically present in the United States in F or J status on 15 September get transitional protection. They may remain without filing an Extension of Stay until the later of the programme end date on their I-20 or DS-2019, or the expiry of post-completion work authorisation — up to a maximum of four years from 15 September. The 60-day F grace period and 30-day J grace period are preserved for this group.

That protection has one condition, and it is the single most consequential sentence in the entire rule: if you leave the United States and re-enter after 15 September, the new rule applies on re-entry.

Harvard’s International Office, whose guidance page is among the most detailed published by any institution, recommends that F-1 and J-1 students and J-1 scholars registered in on-campus programmes for the autumn term try to be physically in the United States on the effective date.

The travel trap

Travel after 15 September will result in a date-certain admission on your Form I-94, matched to the programme end date on your I-20 or DS-2019, rather than the open-ended D/S notation.

That reshapes ordinary decisions. A winter break trip home, a conference abroad, a family emergency — each converts an open-ended admission into a fixed one, which then governs how future extensions and post-completion work authorisation are handled.

Universities are still working through the implications for dual and joint degree programmes, where the “no change of educational objective” language interacts awkwardly with programmes designed around movement between schools.

The litigation, and why it does not change your planning

On 18 August, the Presidents’ Alliance on Higher Education and Immigration, the Association of Independent Colleges and Universities in Massachusetts, and NAFSA filed suit in the US District Court in Boston seeking to invalidate the rule. They also sought an interim stay that would suspend it during proceedings. We covered the filing in our earlier report.

The filings have no immediate effect. The rule takes effect on 15 September unless a court orders otherwise, and no such order has issued. Plan for the rule as written.

Practical steps before Tuesday

• If you can be in the US on 15 September, be there.
• Check the programme end date on your I-20 or DS-2019 now — after the change it becomes the date that governs your stay.
• Postpone non-essential international travel until you have advice specific to your programme.
• If you are considering a change of major or degree level, speak to your international office before the rule takes effect, not after.
• Read the DHS FAQ for the government’s own reading of edge cases.

Answers for students and scholars

When does the duration of status rule end?

15 September 2026, per the DHS final rule published 17 July 2026.

How long will new students be admitted for?

The length of the programme or four years, whichever is shorter, plus a 30-day grace period for departure.

Does the rule affect students already in the US?

Those in F or J status and physically present on 15 September are covered by transitional provisions and can remain without filing an extension until their programme end date or the expiry of post-completion work authorisation, up to four years from that date.

What happens if I travel abroad after 15 September?

The new rule applies when you re-enter, and you will receive a date-certain I-94 matched to your programme end date rather than a duration-of-status admission.

Can I change my major under the new rule?

Graduate students cannot change educational level or major at any point. Undergraduates cannot in their first year, absent specific extenuating circumstances.

Will the lawsuit stop the rule?

It has not so far. The August filing sought an interim stay, but the filings have no immediate effect and the outcome is uncertain. The rule takes effect as scheduled.
