Federal Court Blocks DHS Final Rule Ending Duration of Status for F-1, J-1, and I Nonimmigrants
September 15, 2026
On September 14, 2026, the U.S. District Court for the District of Massachusetts blocked the Department of Homeland Security’s new Final Rule governing F, J, and I nonimmigrants—just one day before the rule was scheduled to take effect. In Presidents’ Alliance on Higher Education and Immigration, et al. v. U.S. Department of Homeland Security, et al., Civil Action No. 26-13799-FDS, U.S. District Judge F. Dennis Saylor IV granted preliminary relief under § 705 of the Administrative Procedure Act (“APA”) and postponed the effective date of the Final Rule while the litigation proceeds.
As a result, the Final Rule did not take effect on September 15, 2026. The existing Duration of Status (D/S) framework remains in place for now.
The Rule That Was Scheduled to Take Effect September 15
As discussed in my earlier analysis, DHS published the Final Rule on July 17, 2026. It would have replaced the longstanding Duration of Status system for F-1 students and J-1 exchange visitors with fixed periods of admission, generally limited to the length of the program and no more than four years.
The rule also would have imposed fixed admission periods on I visa foreign media representatives, created a USCIS Extension of Stay process, and introduced significant new restrictions affecting academic progression, school transfers, changes in educational objectives, grace periods, and other aspects of F-1 status.
The September 14 decision does not merely affect one provision of that regulatory scheme. The court postponed the effective date of the Final Rule itself.
Why the Court Blocked the Rule
The central issue before the court was not whether DHS had authority to regulate immigration generally. Rather, the court examined whether DHS complied with the Administrative Procedure Act when adopting this particular rule.
Under the APA, an agency must reasonably explain its decision, consider relevant evidence, respond meaningfully to significant comments, and establish a rational connection between the facts before the agency and the regulatory action it chooses.
The court concluded that the plaintiffs were likely to succeed in showing that DHS failed to meet those requirements.
Judge Saylor identified four principal deficiencies in DHS’s rulemaking:
DHS failed to conduct a reasoned calculation of the costs and benefits of the Final Rule;
DHS failed to meaningfully consider less burdensome alternatives;
DHS failed to adequately respond to significant comments raising substantial concerns; and
DHS failed to demonstrate a rational connection between the Final Rule and its stated objectives.
These findings are particularly significant because DHS had defended the new system primarily as a measure designed to strengthen national-security screening, prevent fraud and abuse, and reduce overstays.
The court found the connection between those objectives and the fixed-period system insufficiently supported.
For example, with respect to individuals who remain in the United States beyond their authorized stay, the court reasoned that a person willing to overstay unlawfully under the Duration of Status framework could also overstay unlawfully after receiving a fixed expiration date. The court ultimately concluded that DHS’s stated objectives did not bear a reasonable connection to the Final Rule.
The Court Also Found Irreparable Harm
The court separately concluded that implementation of the rule was likely to cause irreparable harm.
One major concern was the uncertainty created by the new Extension of Stay process. Under the Final Rule, students whose programs required additional time could become dependent on discretionary USCIS adjudications, with no administrative appeal from a denial.
According to the record before the court, the effects were not merely theoretical. The court cited evidence that international students had already withdrawn from programs and that one university reported a substantial decrease in international applications.
The court also considered the broader consequences for universities, research, employers, communities, and the U.S. healthcare system. The record included evidence that approximately 16,000 medical residents and fellows were in J-1 status in 2024 and that such physicians frequently serve rural and medically underserved communities.
The Relief Is Nationwide
An important part of the September 14 decision concerns the scope of relief.
The plaintiff organizations represent almost 600 public and private educational institutions, but more than 5,000 higher-education institutions operate across the United States.
The court concluded that applying the existing D/S system to some institutions while imposing the new fixed-period system on others would require parallel regulatory regimes and create substantial confusion—particularly because students may transfer between institutions or pursue joint degrees.
The court therefore postponed the effective date of the Final Rule nationwide.
What Does This Mean for F-1 and J-1 Students Right Now?
The immediate practical consequence is important:
The September 15, 2026 regulatory change has been stopped.
F-1 students and J-1 exchange visitors are not presently being moved into the new fixed-period admission framework described in the Final Rule solely because September 15 has arrived.
The existing Duration of Status framework remains operative while the court's order is in effect.
That also means that the numerous September 15 implementation provisions discussed in my earlier analysis—including the new fixed admission periods and associated Extension of Stay framework—are not presently taking effect as scheduled.
The Final Rule Has Not Been Permanently Vacated
The procedural posture of the case is equally important.
The court did not enter a final judgment permanently invalidating the DHS rule.
The plaintiffs requested, among other things, vacatur under 5 U.S.C. § 706. The court declined to grant that broader relief at this stage. Instead, it took what it described as the more cautious approach of postponing the rule’s effective date under § 705 while the case proceeds.
The court expressly denied the request for vacatur, summary judgment, and other relief without prejudice to renewal.
Accordingly, the litigation is not over. DHS may continue defending the rule, further proceedings will occur in the District Court, and appellate litigation may follow.
For International Students: Do Not Rely on the September 15 Rule
Anyone who reviewed the DHS Final Rule in preparation for September 15 should recognize that the legal situation has now changed.
The Final Rule described in my earlier article remains important because it explains the regulatory framework DHS attempted to implement. But that framework is presently postponed by federal court order and is not in effect as scheduled.
Students and exchange visitors should continue complying with the rules governing their existing F or J status and should not assume that the new fixed-period system applies simply because the original September 15 effective date has passed.
Because this litigation is ongoing, the status of the rule should be checked before making immigration, academic, employment, transfer, OPT, or travel decisions that could depend on it.
Case: Presidents’ Alliance on Higher Education and Immigration, et al. v. U.S. Department of Homeland Security, et al., Civil Action No. 26-13799-FDS (D. Mass.).
Order: September 14, 2026.
Status as of September 15, 2026: Effective date of the DHS Final Rule postponed nationwide under 5 U.S.C. § 705.
