Federal Court Postpones the "Duration of Status" Rule One Day Before It Was Set to Take Effect

On September 14, 2026 — one day before DHS's final rule eliminating "duration of status" (D/S) for F, J, and I nonimmigrants was scheduled to take effect — a federal judge in Massachusetts postponed the rule nationwide. The order came in a lawsuit filed by a coalition of higher-education associations and labor unions, and it means the fixed-admission-period and Extension of Stay framework we covered when the rule published in July (see our earlier article) does not take effect as scheduled. Duration of status remains in place for F-1 students, including those on OPT and STEM OPT, while the case proceeds.

What we know from the court record

• Case: Presidents' Alliance on Higher Education and Immigration, et al. v. U.S. Department of Homeland Security, et al., No. 1:26-cv-13799
• Court: U.S. District Court for the District of Massachusetts
• Judge: F. Dennis Saylor IV
• Complaint and preliminary-injunction motion filed: August 18, 2026
• Motion hearing: September 3, 2026
• Order: Memorandum and order dated September 14, 2026, postponing the rule's effective date
• Legal basis for relief: 5 U.S.C. § 705 (the Administrative Procedure Act's provision letting a reviewing court postpone an agency rule's effective date pending review) — not a traditional Rule 65 preliminary injunction, though it has the same practical effect
• Scope: nationwide, not limited to the named plaintiffs
• Rule being challenged: DHS 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," RIN 1653-AA95, 91 FR 44976, published July 17, 2026, originally effective September 15, 2026

Accordingly, the Final Rule will be postponed pending final resolution of this matter on the merits.Judge F. Dennis Saylor IV, Memorandum and Order, Presidents' Alliance v. DHS, No. 1:26-cv-13799 (D. Mass., September 14, 2026)

Who brought the case

The plaintiffs are NAFSA: Association of International Educators; the Presidents' Alliance on Higher Education and Immigration; the Association of Independent Colleges and Universities in Massachusetts (AICUM); the American Federation of Teachers (AFT); the Graduate Labor Organization, AFT Local 6516; the International Union, United Automobile, Aerospace and Agricultural Implement Workers of America (UAW) and UAW Local 2322; and The NewsGuild-CWA. Their core claim is that the rule is arbitrary and capricious under the Administrative Procedure Act — arguing DHS leaned on thin anecdotal support for its stated national-security rationale and did not meaningfully grapple with the substantial public comments the rule drew before it was finalized.

What is postponed, specifically

Everything the July 17 final rule was set to change on September 15 is now on hold nationwide: F, J, and I nonimmigrants keep their existing "duration of status" admission rather than being switched to a fixed admission period; the new requirement to file Form I-539 for an Extension of Stay before that fixed period expired does not kick in; the shortened 30-day post-completion departure window (down from 60 days) does not take effect; and the new restrictions on changing major, degree level, or transferring schools mid-program do not apply. The pre-existing framework — the one that has governed F-1 status, including post-completion OPT and STEM OPT, for decades — continues to control while the litigation is pending.

What this does not mean

• This is not a final ruling on the merits. The court found the plaintiffs likely to succeed and likely to suffer irreparable harm without relief — that is the standard for this kind of preliminary order, not a final judgment that the rule is unlawful.
• DHS has not withdrawn or rescinded the rule. It remains on the books, published in the Federal Register, simply with its effective date postponed while the case is litigated.
• The order is being described in press coverage as a "preliminary injunction," but the court's own mechanism was a postponement of the effective date under APA § 705 — a technical distinction, but one worth knowing since it shapes what a future appeal actually reviews.
• This ruling does not touch any of DHS's other pending actions covered elsewhere on this site — the proposed elimination of the 60-day grace period (RIN 1615-AD22), the proposed $103,265 H-1B cap-subject fee, or the CPT broadcast-message guidance — all of which sit on entirely separate legal and regulatory tracks.

Why this is not necessarily over

Immigration counsel tracking the case expect DHS to appeal quickly to the U.S. Court of Appeals for the First Circuit, and are cautioning schools, employers, and F-1 students not to treat this as a permanent reprieve. If the First Circuit stays or reverses the district court's order, the fixed-admission-period rule could take effect on short notice, potentially with little advance warning beyond what already exists in the July final rule. The safest posture for anyone who was preparing to file an Extension of Stay application or adjust travel plans around the September 15 deadline is to keep that preparation on hand rather than discarding it, while not treating a new filing as urgent while the postponement holds.

What to do right now

• If you are an F-1 student, including on post-completion OPT or STEM OPT: your status is governed by the pre-existing duration-of-status framework today, not the fixed-period rule — you do not need to file Form I-539 for an Extension of Stay because of the rule that was supposed to take effect September 15.
• If you already filed an EOS application in anticipation of the rule, talk to your DSO or counsel about whether to withdraw it, let it sit, or proceed — the answer depends on your specific SEVIS record and is not the same for everyone.
• Watch for a DHS appeal to the First Circuit; a stay of the district court's order there could revive the fixed-period rule with little notice.
• Keep any transition-period planning you already did (I-20 Program End Dates, cap-gap timing) on file rather than discarding it — this litigation is ongoing, not resolved.

Bottom line

As of September 15, 2026, "duration of status" is still how F-1, J-1, and I admission works — the rule that was supposed to end it has been postponed nationwide by a federal court, one day before it would have taken effect. That is a real, court-ordered pause, not a policy reversal by DHS, and it is very likely to be appealed. Treat this as good news that buys time, not as the final word on whether fixed admission periods for F-1 students are coming.
