DHS Duration of Status Rule Blocked: Key Update for Day 1 CPT Students

1. What Was the DHS Duration of Status Final Rule?

To understand why the court decision matters, it helps to understand what was supposed to change. DHS published its Final Rule on July 17, 2026, with an effective date of September 15, 2026. The regulation would have changed F, J, and I nonimmigrants from Duration of Status to fixed periods of admission.

Under the traditional D/S system, most F-1 students do not receive one fixed date by which they must finish their studies. Instead, they can generally remain in the United States while properly maintaining F-1 status and making appropriate academic progress.

The new rule would have replaced that framework with fixed admission periods.

Among the changes were:

• A fixed period of admission tied to the student's academic program.
• A general maximum admission period of four years.
• A new Extension of Stay process for students needing additional authorized time.
• A shorter post-completion departure period.
• New restrictions affecting certain changes in educational objectives, schools, and subsequent programs.

The Federal Register described the purpose as giving DHS additional oversight and opportunities to evaluate whether F, J, and I nonimmigrants continued maintaining status.

What Happened on September 14?

Several higher-education and labor organizations challenged the Final Rule in federal court.

The plaintiffs include the Presidents' Alliance on Higher Education and Immigration, NAFSA: Association of International Educators, Association of Independent Colleges and Universities in Massachusetts, American Federation of Teachers, UAW organizations, and The NewsGuild-CWA. The lawsuit was filed in the U.S. District Court for the District of Massachusetts in August. 

Then, on September 14—one day before implementation—Judge Saylor granted nationwide preliminary relief.

The court postponed the effective date and prohibited DHS and ICE from implementing the rule while the litigation proceeds. That means the September 15 transition never occurred.

2. Does This Mean the DHS Rule Is Permanently Cancelled?

No. This is the most important distinction for students to understand.

The court did not permanently repeal the Final Rule.

Instead, implementation has been blocked while the legal challenge continues. Brown University's international student office describes the effective date as postponed to a still-indefinite future date pending further court action.

The government may also appeal. So statements such as:

"The four-year F-1 rule has been permanently cancelled."

or

"Duration of Status is permanently safe."

would go beyond what the September 14 ruling establishes.

A more accurate way to describe the situation is:

The DHS Final Rule did not take effect on September 15, 2026. The current Duration of Status framework remains in place while the case continues.

What Does This Mean for Day 1 CPT Students?

For Day 1 CPT students, the immediate impact is significant because many students had been preparing for a completely different immigration framework beginning September 15.

For now, continue following the existing F-1 rules. The court order means the Final Rule's fixed-admission system and associated new restrictions do not currently govern your status.

That means students do not suddenly need to reorganize their academic plans around the new four-year maximum that was scheduled to begin.

However, the ruling does not make CPT requirements disappear.

Students using CPT must still:

• Maintain valid F-1 status.
• Remain properly enrolled.
• Follow their school's academic requirements.
• Receive CPT authorization from their DSO before beginning CPT employment.
• Ensure the practical training is properly related to their curriculum and field of study.
• Follow the CPT dates and employer information listed on their Form I-20.

The court ruling concerns the Duration of Status Final Rule, not the fundamental requirements for maintaining F-1 status or obtaining CPT authorization.

3. Does the Four-Year F-1 Limit Still Apply?

Not currently. One of the biggest concerns surrounding the Final Rule was its fixed admission period.

Had the rule taken effect as planned, F-1 students would generally have received an admission period tied to their academic program but limited to no more than four years at a time. Students requiring additional authorized time could have faced a new Extension of Stay process.

That framework is now postponed.

The University of California, Riverside confirmed after the ruling that the Final Rule's effective date has been postponed and that students and scholars can continue under the existing framework while the court order remains in place.

This is particularly relevant for students pursuing longer programs such as:

• Doctoral degrees
• DBA programs
• PhD programs
• Research-intensive programs
• Master's programs requiring additional completion time

4. Do F-1 Students Need to File an I-539 Extension of Stay Now?

Not simply because September 15 arrived. This is another major change from what students had been preparing for.

Under the blocked Final Rule, some students would eventually have needed to file for an Extension of Stay (EOS) to remain in the United States beyond their fixed admission period.

Because the fixed-admission system did not take effect, students are not currently required to enter that new EOS system merely because the calendar passed September 15.

Yale's Office of International Students and Scholars specifically states that students do not currently need to apply for an Extension of Stay under the fixed-admission-period system the Final Rule would have created. 

That distinction is particularly important if you had been preparing Form I-539 solely because of the new Final Rule. Students who need Form I-539 for some other existing immigration reason should not assume this court decision eliminates that requirement.

However, to help yourself be prepared for future change and alternatives in the future, you may visit Extension of Stay for immigration resources and guidance.

5. What If You're Already Enrolled in Day 1 CPT?

If you're already attending a Day 1 CPT university, don't make unnecessary changes solely because September 15 has passed.

Your immediate priorities remain:

• Maintain your F-1 status. Continue complying with your program's enrollment, attendance, academic, and CPT requirements.
• Follow your current I-20. Do not assume that the blocked rule creates new dates or automatically changes information already associated with your SEVIS record.
• Keep your CPT authorization current. Continue following the employment, employer, and authorization dates provided by your DSO.
• Stay in contact with your DSO. Universities are monitoring this litigation closely, and your school's international student office should remain an important source for program-specific guidance.

Most importantly, do not file something solely because you were told months ago that September 15 would trigger a new requirement. Verify whether that requirement still exists under the current rules.

What If You're Planning to Start Day 1 CPT Soon?

You have more breathing room—but you should still plan carefully.

Students previously choosing programs based on the expected September 15 changes can now evaluate their options under the existing D/S framework.

When comparing Day 1 CPT universities, consider:

• Whether the degree logically follows your previous education.
• Whether the major aligns with your employment.
• CPT eligibility and authorization requirements.
• On-site attendance frequency.
• Tuition and scholarships.
• Program length.
• Location and travel requirements.
• Academic workload.
• University accreditation.
• Career relevance.

The court decision should not change the fundamental principle behind choosing a Day 1 CPT program: Choose a legitimate academic program that supports your education and career—not simply the program that appears easiest for maintaining employment.

What If You're on OPT or STEM OPT?

Students currently on OPT or STEM OPT should also continue following the existing requirements applicable to their employment authorization.

If you were planning your next academic program because OPT/STEM OPT is approaching its end, you should still plan ahead. But your decision should no longer assume that the fixed-period Final Rule automatically took effect September 15.

For example, you may still be evaluating:

OPT/STEM OPT → new academic program → CPT → future H-1B attempt

That pathway requires careful planning regardless of the court case. The difference is that the new fixed-admission framework is not currently part of the equation.

What If Your H-1B Was Not Selected?

Students whose H-1B registration was not selected may have been paying especially close attention to September 15.

The court ruling does not create a new H-1B benefit or extend OPT. You still need to maintain a valid immigration basis for remaining in the United States.

Depending on your circumstances, options may include remaining on valid OPT/STEM OPT, pursuing another appropriate academic program, considering CPT if eligible, exploring another immigration classification, pursuing a future H-1B opportunity, or departing the United States.

But the blocked Final Rule means you do not currently need to incorporate its new fixed-admission and EOS system into that decision.

6. Should You Still Choose a DBA Instead of a Second Master's?

For some students, yes—but for academic and career reasons rather than because the September 15 rule took effect.

Before the injunction, doctoral programs received increased attention because students were considering how the Final Rule's educational-level restrictions could affect subsequent degrees. Those restrictions are not currently operative.

However, students who already hold a master's degree may still find that moving to a Doctor of Business Administration (DBA) provides stronger academic progression than completing another similar master's degree.

A DBA can also support career goals in:

• Executive leadership
• Business analytics
• Information systems
• Healthcare administration
• Consulting
• Strategy
• Technology management
• Entrepreneurship

Our university partners currently offer multiple DBA options for international students.

7. Before vs. Now: What Changed After the Court Decision?

The situation can change again as litigation proceeds, so this table describes the status as of September 16, 2026. 

What Should Day 1 CPT Students Do Now?

The best response to the court decision isn't to ignore the Final Rule completely.

It's to stop treating September 15 as an immediate filing deadline while remaining prepared for future developments.

Students should:

1. Continue following the existing F-1/D/S framework.
2. Maintain enrollment and CPT compliance.
3. Check your I-20 and SEVIS information for accuracy.
4. Talk to your DSO before making major transfers or program changes.
5. Do not assume you need an EOS solely because the Final Rule had been scheduled to take effect.
6. Keep records of your academic progress and CPT authorization.
7. Monitor the court case, DHS, ICE/SEVP, and university announcements.

Students considering travel should be especially cautious about relying on old guidance prepared under the assumption that the rule would become effective September 15. USC's international student office is currently advising students to consult an international student advisor before making significant travel or immigration decisions while the litigation continues.

8. Frequently Asked Questions

Was the DHS Duration of Status rule blocked?

Yes. On September 14, 2026, a federal judge granted nationwide preliminary relief preventing DHS and ICE from implementing the Final Rule while the lawsuit continues.

Did the new D/S rule take effect on September 15?

No. The scheduled September 15 effective date was postponed by the court order. 

Is Duration of Status still in effect for F-1 students?

Yes, for now. The existing D/S framework remains in place while the preliminary relief is effective.

Is the four-year F-1 rule cancelled permanently?

No. It is currently blocked from taking effect, but the litigation is ongoing. The government may appeal, and future court action could change the rule's status. 

Do Day 1 CPT students need to file I-539 because of the new rule?

Not simply because September 15 passed. The new fixed-admission/EOS framework is not currently operative. Students may still need Form I-539 for other immigration reasons depending on their individual circumstances. 

Can students still transfer Day 1 CPT universities?

The Final Rule's new transfer restrictions did not take effect. However, existing SEVIS transfer, F-1, enrollment, and CPT requirements continue to apply.

Can I still pursue a second master's degree?

The Final Rule's new educational-level restrictions are not currently operative. That does not mean every second master's is automatically appropriate; students should still evaluate academic progression and comply with existing F-1 requirements.

Should I still prepare for the Final Rule?

It is reasonable to remain informed because the litigation isn't finished. However, students should make current immigration decisions based on the rules actually in effect today, not on requirements that were postponed.

9. Final Thoughts: The Rule Is Paused, Not Gone

For international students, the September 14 court decision provides an important period of stability The DHS Duration of Status Final Rule did not take effect on September 15, 2026, meaning F-1 students continue under the existing D/S framework for now. The proposed fixed admission periods, four-year framework, new Extension of Stay system, and associated educational restrictions are not currently operative.

For Day 1 CPT students, this means there is no need to make sudden academic or immigration changes solely because September 15 arrived. Continue maintaining F-1 status, follow your school's CPT requirements, keep your academic and employment records current, and work closely with your DSO.

But don't delete the Final Rule from your planning folder just yet.

The court's action is preliminary, the underlying lawsuit continues, and the government could appeal. Students planning transfers, new degrees, OPT/STEM OPT transitions, Day 1 CPT, or longer doctoral programs should continue monitoring developments carefully.
