Duration of Status (D/S) and the Fixed-Stay Rule: What Is Published, What Is Blocked, What Applies Now

NEW Published 31 October 2026

A final rule would replace duration of status with fixed admission periods. A federal court postponed its effective date one day before it was due to start. Here is what the rule says, what the court ordered, and what applies to F-1 students today.

SECTION 01What Duration of Status Is

RULE — D/S means your admission lasts as long as your status does. Since 1978, F-1 students have been admitted not to a calendar date but "for duration of status". The regulation the system still runs on defines it as the time during which an F-1 student is pursuing a full course of study at an SEVP-certified institution, or engaging in authorised practical training following completion of studies, and is making normal progress towards completing the course of study. Your Form I-94 records this as "D/S" in place of an admit-until date. There is no fixed expiry to count down from: your stay is lawful while you maintain status, and your school's Designated School Official (DSO) and the SEVIS record are the machinery that evidences it.

RULE — Under D/S, extensions and programme changes are DSO actions, not USCIS filings. The same regulation states that an F-1 student admitted for duration of status "is not required to apply for extension of stay as long as the student is maintaining status". If you cannot finish by your programme end date, your DSO can extend your programme in SEVIS for compelling academic or medical reasons. Transfers to another certified school, and changes of educational level, likewise run through SEVIS procedures and a new Form I-20 — see our guide to SEVIS transfers and new programmes. Keep that baseline in mind: everything in the next section is a description of a system that, as of 31 October 2026, has never operated for a single day.

SECTION 02What the Final Rule Would Change

RULE (published, not in effect) — The rule's own terms. On 17 July 2026, the Department of Homeland Security published the final rule "Establishing a Fixed Time Period of Admission and an Extension of Stay Procedure for Nonimmigrant Academic Students, Exchange Visitors, and Representatives of Foreign Information Media" (91 FR 44976; RIN 1653-AA95). Its summary states that it changes "the admission period in the F, J, and I classifications from duration of status to an admission for a fixed time period". Its printed effective date was 15 September 2026. If it ever takes effect, its core terms for F-1 students are these:

Admission period. Instead of D/S, a fixed period of stay up to the programme end date on the Form I-20, not to exceed four years (with shorter caps the rule sets for English-language training, 24 months, and public high school, 12 months). Representatives of foreign information media (I status) would be admitted for up to 240 days.

Departure period. After the programme end date, an additional 30 days to depart or take other action — replacing the 60-day grace period F-1 students have today.

Extensions. Anyone needing more time — to finish a programme, begin a new programme, or undertake practical training — would have to apply to USCIS for an extension of stay "in the manner and on the form prescribed by USCIS", which in practice is Form I-539, with the fee, biometrics and the possibility of a discretionary, unappealable decision that the reviewing court described in its order. The rule also adds a transition provision (a new paragraph (m) in 8 CFR 214.1) for people already in D/S on the effective date, allowing them to continue to their programme end date or up to four years, whichever comes first.

Read those terms as a description of a published document, not of your obligations. None of them applied on 15 September 2026, and none applies today, for the reason in the next section.

SECTION 03The Lawsuit, and What the Court Actually Ordered

RULE — Who sued, and when. On 18 August 2026, a coalition led by the Presidents' Alliance on Higher Education and Immigration and NAFSA — with university associations and labour unions, including one representing journalists — sued the Department of Homeland Security in the U.S. District Court for the District of Massachusetts (No. 1:26-cv-13799), arguing the rule was adopted in violation of the Administrative Procedure Act (APA). A hearing was held on 3 September 2026.

RULE — The operative act is a postponement of the effective date, nationwide. On 14 September 2026, Judge F. Dennis Saylor IV issued a 48-page Memorandum and Order (Document 50 in the case). We have read the filed order itself. The court found that the plaintiffs "are likely to succeed on the merits of their claims" — that the rule is likely arbitrary and capricious under the APA — that immediate irreparable harm would follow if the rule took effect, and that the balance of equities and the public interest favoured relief. It then took, in its own words, "the more cautious approach of postponing the effective date of the Final Rule", rather than vacating the rule outright. Its conclusion reads:

"Plaintiffs' motion for APA § 705 relief, a preliminary injunction, or, in the alternative, summary judgment, is GRANTED to the extent that it seeks to postpone the effective date of the Final Rule pursuant to the Administrative Procedure Act, 5 U.S.C. § 705. To the extent that plaintiffs seek vacatur of the Final Rule, summary judgment, or other relief, the motion is DENIED without prejudice to its renewal."

Three precision points follow from the order's own text. First, the mechanism is section 705 of the APA, which empowers a reviewing court "to postpone the effective date of an agency action" — the rule's 15 September 2026 effective date is postponed "pending final resolution of this matter on the merits", so the rule has never acquired an operative effective date. Secondly, the relief is expressly nationwide: the court reasoned that section 705 permits relief beyond the parties, that the plaintiffs represent almost 600 institutions out of more than 5,000, and that party-limited relief "would require maintaining parallel regulatory regimes" and "generate chaos and confusion". It held it had "the statutory authority to stay the Final Rule in its entirety". Thirdly, the rule was not cancelled: the request to vacate it was denied without prejudice, which is why this story has a next chapter (Section 06). Descriptions of the order as also "prohibiting DHS and ICE from implementing the rule" — the plaintiffs' own summary — are accurate as a practical consequence: an agency cannot implement a rule whose effective date a court has postponed. But the postponement is the act the court performed, and it is the postponement that any later court would have to lift.

SECTION 04What Applies to You Today

RULE — Your I-94 should still say D/S, and the 60-day grace period stands. Because the admission framework never changed, nothing about your documents was due to change on 15 September 2026 or since. DHS's own student guidance, live today, states the current position in terms: "Once you complete your program of study and any authorized period of practical training, F students have 60 days after completion of your program (the program end date on your Form I-20) to leave the United States." Thirty days is the blocked rule's figure; sixty is the law in force. For the full map of the periods that follow different kinds of status endings, see our guide to end-of-status grace periods, and for staying in status day to day, our guide to maintaining F-1 status.

RULE — Travel runs on the ordinary rules. The question circulating most — "is it safe to travel to India after September 15?" — assumes the fixed-stay system began on that date. It did not: the rule is not in effect, so the normal travel and re-entry rules are the ones that apply, unchanged — a valid passport and visa, a current Form I-20 with a travel signature, and re-entry in F-1 status for D/S. That is a statement about which legal framework governs, not a guarantee about any individual's inspection; prepare exactly as our F-1 travel and re-entry guide sets out, and talk to your DSO before you book, as DHS's guidance itself advises.

RULE — Starting a new programme does not require an I-539 today. The second circulating claim — put to students whose STEM OPT ends in early 2027 and who plan to start a PhD or another programme — is that they "must file an Extension of Stay (Form I-539)" for the new programme. That filing exists only inside the blocked rule. Under the law in force, DHS's student guidance lists exactly three DSO routes for extending a stay after a programme: "Transfer to another school. Change your education level (e.g. bachelor's to master's). Apply to change status to another visa status." Changing level or school is a SEVIS action your new school's DSO performs; no new USCIS extension-of-stay procedure has been created, because the rule that would have created it is postponed.

ADVICE — A practical tell you can check yourself. If the fixed-stay system were operating, USCIS would be issuing the new editions of the forms the rule depends on. It is not. As of 31 October 2026, USCIS's own form pages still list Form I-539 at edition date 08/28/24 and Form I-765 at edition date 08/21/25 — the pre-rule editions. Form editions are a small thing, but they are the kind of small thing that is hard to fake: the paperwork of the new system does not exist because the new system is not running.

SECTION 05Why the Regulation Text May Look Different

RULE — eCFR already displays the new wording. If you open the current Code of Federal Regulations — we checked the official eCFR text, current through its 29 October 2026 issue date — you will find that 8 CFR 214.2(f)(5) is now headed "Period of stay" and reads: "An F-1 student is admitted for a fixed period of time, which is the period necessary to complete the course of study indicated on the Form I-20, or successor form, not to exceed a period of 4 years", with a further 30 days to depart. Paragraph (f)(7) is now an extension-of-stay procedure run by USCIS, and 8 CFR 214.1 contains the rule's paragraph (m) transition provisions, printed with their 15 September 2026 dates. Neither section carries any note about the lawsuit or the postponement; the only editorial note in section 214.1 is the standard pointer to the List of CFR Sections Affected. A reader who stops there — as some university and law-firm pages published in the summer apparently did — will describe the fixed-stay system as current law.

RULE — Why the displayed text is not the operative law. The explanation is mechanical, and it matters. The amendments were published as a final rule, and the codified text was updated to display them. What the District Court postponed was the amendments' effective date — the legal switch that makes displayed text into binding law. Under the court's order, that switch has never been thrown: the pre-amendment provisions (duration of status under the former paragraph (f)(5), DSO programme extensions, the 60-day period) remain the operative law, which is why the court's own order quotes and applies them, and why DHS's live student guidance still teaches the 60-day period and the DSO routes. We state this as the position the documents compel, with one honesty limit: eCFR does not annotate this litigation anywhere in the affected sections, so nothing on the eCFR page itself will tell you any of this. For this rule, the Federal Register document and the court order — not the CFR display — are where the current position is found.

SECTION 06What Happens Next

RULE — The appeal does not lift the block. On 30 September 2026, the government filed a notice of appeal to the U.S. Court of Appeals for the First Circuit. Filing an appeal does not itself change the district court's order, and as of 31 October 2026 no stay of the postponement has been granted; the plaintiffs' litigation page, checked today, states the current status as: "The D/S final rule remains blocked nationwide while the litigation continues." At an October status conference the government said it plans to ask the First Circuit to expedite the appeal — a request for speed, which is a different thing from a stay that would switch the rule on. Treat any report that "the appeal reinstated the rule" as wrong unless a court order says so.

ADVICE — The dates to watch (as reported by the plaintiffs' litigation tracker, a party source). In the First Circuit, the government's opening brief is due 9 November 2026 and the plaintiffs' response brief 9 December 2026, with a government reply to follow. In the district court, cross-motions for summary judgment were due on 30 October 2026, with replies due 2 November; as of the evening of 31 October 2026, no ruling on those motions has been reported. A final judgment in the district court, or a First Circuit decision reversing the postponement, could change the position — and if the block were ever lifted, the rule could take effect on a new effective date set after the litigation, potentially on relatively short notice. That is the honest urgency of this story: not that anything is required of you now, but that the position is stable only while the postponement stands. We will update this page when there is a ruling or a stay decision to report.

SECTION 07One Separate Action This Order Does Not Touch: CPT Guidance

RULE — Do not conflate the two. SEVP separately issued guidance to DSOs about Curricular Practical Training in August 2026 (broadcast messages dated 12 and 24 August 2026, as reported by universities and education press). That guidance is a different agency action from the fixed-stay rule: it is not mentioned in, and is not affected by, the District Court's postponement order, and nothing in this article describes or evaluates its terms. If your plans involve CPT, the order discussed here changes nothing about it — speak to your DSO, and see our guide to on-campus work and CPT for the framework that guidance sits within.

Verified on 31 October 2026 against: the final rule as published in the Federal Register (91 FR 44976, document 2026-14439, RIN 1653-AA95), read in full text, including its summary, its printed effective date of 15 September 2026 and its core terms; the filed Memorandum and Order in Presidents' Alliance on Higher Education and Immigration v. U.S. Department of Homeland Security, No. 1:26-cv-13799 (D. Mass., Document 50, filed 14 September 2026), read in full — the order grants postponement of the rule's effective date under 5 U.S.C. § 705, nationwide, and denies vacatur without prejudice; the current eCFR text of 8 CFR 214.1 and 214.2 (issue date 29 October 2026), which displays the amendments with no litigation annotation; DHS's Study in the States "Maintaining Status" page, live today, for the 60-day period and DSO routes; and USCIS's Form I-539 and Form I-765 pages, live today, for the form-edition check. Two items rest on weaker footing and are flagged where used: the litigation schedule and the "no stay" position rest on the plaintiffs' litigation tracker (a party source, checked 31 October 2026) and secondary docket reporting — no stay of the postponement has been reported anywhere as of that date, and the PACER docket itself was not read directly. The August 2026 SEVP CPT broadcast messages are DSO-distributed documents; no official ICE page for them could be read, so this article records only their existence and separateness, not their terms. A Federal Register search on 31 October 2026 found no later DHS document postponing, correcting or withdrawing this rule — the only postponement is the court's.
