US ends open-ended student stays: what the new DHS rule means for Pakistani F-1 students

Does this affect Pakistanis specifically, or everyone? This applies to all F-1 and J-1 visa holders worldwide — it is not a Pakistan-specific rule. It lands hardest on students in long programmes: PhDs, dual degrees, and anyone likely to need more than four years. If you are planning a US PhD (Segment 4), read this before you finalise your programme plan, not after. What is changing Until now, F-1 and J-1 students were admitted for "duration of status" (D/S) — you could stay as long as you remained enrolled and in good standing, with no fixed expiry date on your I-94. From 15 September 2026, that ends for new admissions. You will instead be admitted for a fixed period matching your programme length, capped at four years. If your programme runs longer — a typical PhD, for example — you will need to file an Extension of Stay (EOS) with USCIS before your admitted period runs out. Missing that deadline risks falling out of status. The post-completion grace period for F-1 students shrinks from 60 days to 30 days. Do not assume the same change applies identically to J-1; check your category against the final rule and your DS-2019. If you are already in the US on F-1/J-1 under D/S You are not cut off overnight on 15 September. Under the transition provisions, if you are properly maintaining status on the effective date and were admitted for D/S, you are generally authorised to remain until the later of your programme end date on the I-20/DS-2019 (or EAD end date, where applicable), not to exceed four years from 15 September 2026, plus the applicable departure period. Separately: if you leave the United States and re-enter on or after 15 September 2026, you will be admitted under the new fixed-date I-94 system. Plan travel with that conversion in mind — do not assume a short trip is administratively neutral. What to do now if you are planning a US PhD • Build EOS filing into your multi-year plan from day one — who tracks the I-94 end date, and when does Form I-539 need to be lodged? • Ask your future DSO / international student office how they will support EOS filings under the new rule; university practice will matter as much as the regulation text. • Do not treat a five- or six-year PhD offer as "open-ended stay" the way D/S used to feel. The programme can still be long; your authorised stay will not automatically match it without a timely extension. What this means if you are working with a consultant Ask them directly whether they know about this rule. A consultant who has not mentioned it either is not tracking US policy closely or has not updated their advice. If you are being sold a multi-year US PhD placement, ask specifically how EOS filing will be handled and who is responsible for tracking your admission expiry date. This is not something a consultant can "process" for a flat fee and forget — it now requires ongoing monitoring for the life of your programme. Questions to ask your consultant 1. Under the September 2026 rule, what fixed admission period should I expect on my first I-94 for this programme? 2. Who files the Extension of Stay if my PhD runs past four years — me, the university, or you — and who calendars the deadline? 3. If I travel internationally after 15 September 2026 while still on D/S transition status, how does re-entry change my authorised stay? 4. What happens to OPT / STEM OPT timing under the new fixed-period framework for my profile? Uncertainty / subject to change DHS and USCIS guidance on adjudication and filing practice is still developing ahead of the effective date. Litigation or Congressional Review Act action could still alter the timeline; until that happens, plan against 15 September 2026. We will update this post as implementation details land.
