F-1 Students and H-1B: What Has Actually Changed?

The fixed-period final rule, a nationwide pause, H-1B selection, and litigation over a high fee are moving at the same time. The most common mistake is not missing the news but treating a proposal as in force, or a pause as a permanent repeal.

1. Introduction

Over the preceding weeks, several F-1 student and H-1B developments were unfolding at once: a final rule approaching its effective date, a nationwide federal-court pause, a comment period opening for another proposed rule, and litigation over a high fee still on appeal. The easiest planning error is not missing a headline. It is treating a proposal as effective law, a temporary pause as permanent repeal, or an order from one federal district court as irrelevant outside that state.

This article provides a status snapshot and then examines the striking decision to pause the fixed-period-of-admission rule one day before it was due to take effect. The closing commentary does not replace advice from an attorney or a school’s designated school official (DSO) on an individual case.

2. Status snapshot as of September 18, 2026, Eastern Time

How to read the table: “Postponed nationwide” does not mean “repealed.” “USCIS is not currently collecting” does not mean “permanently canceled.” An NPRM does not mean implementation next week.

3. The fixed-period rule: a nationwide pause the night before implementation

3.1 The timeline

• July 17, 2026: DHS published a final rule in the Federal Register that would replace the decades-old duration-of-status framework with a fixed “Admit Until Date.” F and J admissions would generally be limited to about four years, with separate days around arrival and departure. Many people needing more time would have to file Form I-539. The rule also included limits on certain academic moves and a shorter departure grace period.
• Scheduled effective date: September 15, 2026. Universities, DSOs, students, and families were preparing for an imminent change. Official channels, including ICE Study in the States, had published transition guidance.
• September 14, 2026, one day before the effective date: A federal district court in Massachusetts issued a preliminary order. Under 5 U.S.C. §705 of the Administrative Procedure Act (APA), it postponed the rule’s effective date and preliminarily barred the defendants from implementing it until further court order or final resolution of the merits. At the same time, the court did not grant the plaintiffs’ request to vacate the rule itself, although that request could be renewed. The court pressed pause; it did not tear up the rule text on the spot.

As a result, when the scheduled effective date arrived, the duration-of-status framework remained in place nationwide. There was no general switch to a fixed admission period and no new universal obligation to file Form I-539 arising from this final rule itself.

3.2 The separation-of-powers reading

This episode should not be reduced either to “the executive can change the rule at will” or to “a court can casually veto policy.”

1. The executive branch can issue a final immigration-administration rule through APA rulemaking, subject to requirements including public comment, a reasoned explanation, and an adequate record.

2. In litigation, the judicial branch examines whether the rule complies with the APA—for example, whether it is arbitrary or capricious and whether the agency reasonably addressed important comments and costs. Section 705 permits a court to postpone a rule’s effective date during the case to prevent potentially irreparable harm.

3. Postponement is not vacatur. A postponement leaves the rule text in existence while its effect is paused. A decision on the merits, an appeal, remand, or new rulemaking could still follow.

4. The relief here was framed as covering the entire final rule and had practical nationwide effect. It is not simply protection for named plaintiffs, but it remains a temporary litigation posture, not a permanent act of Congress.

The same logic helps explain the other issues discussed below: the $100,000 requirement, whose implementation was vacated but which the government says it would revive if the order falls; the proposed approximately $103,265 surcharge; and the proposed elimination of the 60-day grace period. A headline announcement is not a final outcome. Court orders, appeals, and comment periods can repeatedly change which rules can be used today.

3.3 What an unfinished case means

• The government may seek an appeal or further relief.
• The plaintiffs may seek a stronger remedy, such as vacatur, later in the litigation.
• DHS could, in theory, address deficiencies in procedure or reasoning identified by the court through amendment, remand, or a new rulemaking.

“D/S still applies this week” was an actionable fact on the article date. “D/S will apply forever” was not a justified conclusion.

4. Immediate implications for three groups

Current F-1 and J-1 students

In the near term, maintenance of status still follows the existing D/S, SEVIS, and school-compliance framework. Students did not need to rush an I-539 filing on the September 15 “switch date” solely because of this paused final rule. If a joint degree, school transfer, or change of major had been altered in anticipation of the final rule’s restrictions, the student should check with the DSO whether the previous framework is available again under the injunction and whether the school has reversed any internal transition procedure.

Students using or preparing to seek OPT or STEM OPT

While the injunction remains effective, the fixed-period final rule does not impose a new general requirement to pair OPT with an extension-of-status filing. Existing transition mechanisms such as Cap-Gap should still be followed according to current USCIS and school guidance and legal advice. Some travel, reentry, and transition windows appeared in the final rule’s provisions for switching systems. With the rule postponed, those special switch-related calendars should not be assumed to apply by default; use current DSO and USCIS guidance.

Candidates entering the H-1B selection process

The FY2027 weighted-selection rule has already been used for one season. On the sponsorship-cost side, the $100,000 payment is not currently being collected, but the proposed cap surcharge of about $103,265 was still in its comment period. DHS also said it intended to resume the $100,000 collection path if the relevant order were overturned. The actionable near-term distinction is that the selection rule has changed while the question of which fee is currently payable is separate. Candidates should not base their only decision on an outdated fee assumption.

5. Commentary

What made planning harder in these weeks was not a single policy becoming “looser” or “tighter.” Along one immigration-status pathway, executive rules, court postponement or vacatur, appeals, and new proposals were operating simultaneously. When information is abundant, the rational first move is to label each measure in force, temporarily paused, or only proposed, and only then consider an individual timetable. A dramatic headline alone should not drive an irreversible choice.

6. Developments to watch

1. Presidents’ Alliance v. DHS: appeals, merits proceedings, any change to the §705 order, and procedural dates such as the next status conference reflected in the public docket.

2. California v. Mullin and the $100,000 requirement: the First Circuit merits appeal, any request for a stay or review by a higher court, and changes to USCIS’s H-1B FAQ on collection.

3. The approximately $103,265 NPRM: any final-rule timetable after the comment period expected to close around September 24, 2026.

4. The 60-day grace-period NPRM: comments expected through about November 10, 2026, and whether a final rule and effective date follow.

5. The next H-1B registration season: implementation details of wage-level-weighted selection and any changes to the evidence required after selection.

6. ICE Study in the States and SEVP: updates to fixed-period pages and operating guidance following the injunction. Transition instructions published before the court order may lag behind it.
