F-1 Rule Challenged in Court: Will It Take Effect on September 15? Litigation Updates and PI Analysis
The Department of Homeland Security’s (DHS) upcoming F-1 rule is now facing a federal lawsuit. Many international students are asking whether the lawsuit could stop the rule and whether it will still take effect on September 15.
The answer is not yet clear, but the case is moving quickly. The next few weeks will be critical.
Why Is the F-1 Rule Being Challenged?
On August 18, 2026, a coalition of education organizations and labor unions, including NAFSA, the Presidents’ Alliance, and the AFT, filed a lawsuit against DHS in the U.S. District Court for the District of Massachusetts. The lawsuit challenges the F-1, J-1, and related status rule scheduled to take effect on September 15, 2026.
One of the most significant changes in the rule is the elimination of the long-standing Duration of Status (D/S) framework. Under the proposed system, students would instead receive fixed admission and authorized stay periods. The rule also introduces restrictions involving F-1 school transfers, program changes, degree programs, and grace periods.
The plaintiffs argue that the rule will have serious consequences for international students and educational institutions, and they are asking the court to set it aside. Along with the complaint, the plaintiffs filed a motion for a Preliminary Injunction (PI). They also requested temporary relief under Section 705 of the Administrative Procedure Act (APA), asking the court to pause the rule before the case is finally decided so that it does not take effect on September 15.
Current Case Timeline
The schedule is very tight:
August 18: Lawsuit filed and PI motion submitted
August 31: Government response due
September 3: Court hearing on the PI motion
September 15: Scheduled effective date of the rule
The September 3 PI hearing is one of the most important upcoming milestones. However, the court is not required to issue a decision on the same day and may release a written ruling later.
If the PI Is Granted, Does That Mean the Rule Is Cancelled?
No. If the court grants a PI, it would generally temporarily prevent the rule from taking effect while the lawsuit is pending. It would not mean that the plaintiffs have already won the case.
Likewise, if the PI is denied, that would not necessarily mean the plaintiffs have lost. The lawsuit could still proceed to further review and a final decision.
How Likely Is It That the F-1 Rule Will Be Paused?
Based on the currently available filings, the PI motion appears to have a meaningful chance of success. This is not a lawsuit brought by only a few individual students. It was filed by a coalition of education organizations and unions, supported by declarations from multiple universities and educational institutions explaining the practical effects the rule may have on students and schools.
The plaintiffs have also raised specific challenges under the APA, including concerns about how the government addressed public comments, policy costs, and burdens on educational institutions during the rulemaking process. These issues may be important factors in the court’s review.
At the same time, DHS has broad administrative authority over the admission, authorized stay, and F-1 status management of foreign students. The government will likely raise legal arguments in support of the rule. For now, there is no certainty that the court will pause the rule.
What Should F-1 Students Do Now?
At this time, the F-1 rule is still scheduled to take effect on September 15, 2026. Unless and until the court issues an order pausing implementation, students should prepare based on the possibility that the rule will take effect.
Students who are already in the United States and properly maintaining F-1 status do not need to immediately change their current academic plans because of the lawsuit. However, they should review their I-94 records, I-20 Program End Dates, and OPT or STEM OPT timelines in advance.
Students who may soon travel internationally, apply for OPT, transfer schools, begin a new degree program, or extend an I-20 should confirm the relevant arrangements with their school’s international student office. They should also closely follow the September 3 hearing and any court order issued afterward.
There is no need to panic, but students should not assume that the rule will definitely be stopped. Ding Babb Law Group will continue to monitor developments in the F-1 rule litigation.
