International students planning to study or continue their education in the United States received an important update on September 14, 2026.
A federal judge in Massachusetts postponed the effective date of the Department of Homeland Security’s 2026 Duration of Status (D/S) final rule, which had been scheduled to take effect on September 15.
The order means the new fixed-admission system is not currently in effect. Existing Duration of Status treatment for F-1 students remains in place while the litigation continues.
What is the D/S rule?
Duration of Status, commonly written as D/S, has historically allowed qualifying F-1 students to remain in the United States while they maintain the requirements of their student status and complete their authorized program and related activities.
DHS’s 2026 final rule proposed replacing that framework with fixed periods of admission for F, J and I nonimmigrants, together with additional extension-of-stay procedures.
What happened on September 14, 2026?
The U.S. District Court for the District of Massachusetts issued a preliminary injunction postponing the effective date of the final rule.
The rule had been scheduled to become effective on September 15, 2026. The court acted one day earlier.
The relief applies nationwide. The court explained that nationwide relief would avoid maintaining parallel regulatory systems and reduce confusion for students and institutions, particularly because students can transfer between institutions or pursue joint degrees.
Does the court decision mean the D/S rule is gone?
No. This is a key distinction for international students.
The court’s ruling is a preliminary injunction, not a final decision on the merits of the lawsuit. The judge postponed the rule’s effective date but did not vacate the rule. That means future court action could affect what happens next.
For students making education plans, the safest approach is to distinguish between:
What was proposed under the new rule and What is actually in effect today. At present, the new fixed-admission system is postponed.
What does this mean for students applying to U.S. universities?
For prospective F-1 students, the September 14 ruling does not cancel university admission requirements, visa requirements or normal F-1 compliance requirements.
Students should still plan around the academic program they intend to pursue, maintain the required immigration documentation and follow the instructions provided by their university’s international student office.
The injunction primarily means that the new fixed-period D/S framework scheduled for September 15 is currently not operative.
What about international students already in the USA?
Current international-office guidance states that students already maintaining F-1 status remain under the existing Duration of Status framework for now.
That is especially relevant to students considering:
- university transfers
- continuing into another academic program
- completing their current degree
- planning OPT
- managing a change in educational objective
The new restrictions that were part of the fixed-admission rule are not currently operative while the effective date is postponed.
What changes were included in the DHS rule?
The final rule would have changed several aspects of the F-1 system.
DHS proposed fixed admission periods generally tied to the program length, subject to a four-year limit, and created procedures for requesting an extension of stay. The rule also included restrictions involving F-1 transfers and changes to educational objectives.
Because those changes are currently postponed, students should not assume those September 15 requirements are already part of the active F-1 system.
Does this affect university transfers?
The proposed rule included new restrictions involving transfers and changes in educational objectives, including additional requirements for some students at the graduate level.
Those provisions were part of the rule that was scheduled to take effect on September 15 and are therefore currently postponed along with the rest of the rule.
For a student considering a transfer, however, the existing transfer procedures and DSO process still matter.
The injunction should not be interpreted as eliminating the need to coordinate a transfer with the relevant school.
Does it affect OPT?
The September 14 injunction does not itself create a new OPT benefit or remove existing OPT requirements.
Current university guidance following the court order says there are no immediate changes to the current OPT application process as a result of the injunction.
Students should continue checking current USCIS guidance and working with their school’s international student office.
What about Form I-539 and Form I-765?
The original September 14 newsletter advised some applicants to consider waiting before filing because USCIS had been preparing form changes associated with the D/S rule.
This point needs caution.
The court postponed the rule before its scheduled effective date, and USCIS’s currently indexed I-539 instructions still show the 08/28/24 edition.
Students should therefore avoid relying on an old announcement about a future form edition. Before filing, they should check the current USCIS form page, edition date and filing instructions that apply to their particular application.
A blanket instruction to “wait to file” can be problematic when an individual’s filing deadline or immigration circumstances are different.
Why did the judge postpone the rule?
The court’s preliminary decision said the plaintiffs demonstrated a substantial likelihood of success on their argument that the rulemaking was arbitrary and capricious under the Administrative Procedure Act.
The judge identified concerns with DHS’s cost-benefit analysis, alternative approaches, treatment of significant public comments and the relationship between the final rule and its stated objectives.
Again, these are findings supporting preliminary relief, not a final determination ending the litigation.
What should international students do now?
Students planning to study in the United States should continue using current university and government guidance rather than planning around the postponed September 15 framework.
For prospective students, that means continuing to evaluate programs, admission requirements, tuition, location, start dates and university transfer considerations based on current information.
For students already in F-1 status, it means continuing to comply with the existing requirements and coordinating changes with the DSO.
The legal situation remains active, so major immigration decisions should be checked against the latest official information.
What happens next?
The litigation continues, with current international-education updates identifying October 2, 2026 as the next court date/status conference.
The government is expected to continue challenging the injunction, so international students should treat the situation as an evolving legal matter rather than a permanently resolved policy change.
