Optional Practical Training Under DHS’s Final Rule (Part I) and How Fixed Periods of Admission Change the Immigration Framework for F-1 Students

Optional Practical Training (OPT) is an important benefits available to F-1 students. Every year, tens of thousands of international students rely on OPT to obtain practical experience in their field of study, transition into the American workforce, and, for many, pursue H-1B status or employment-based permanent residence.

The Department of Homeland Security’s July 17, 2026 Final Rule, Establishing a Fixed Time Period of Admission and an Extension of Stay Procedure for Nonimmigrant Academic Students, Exchange Visitors, and Representatives of Foreign Information Media, 91 Fed. Reg. 44976 (July 17, 2026).,  does not eliminate OPT. Instead, it changes the immigration framework within which OPT operates. For more than forty years, most F-1 students remained in the United States under Duration of Status (D/S). Under the Final Rule, DHS replaces that system with fixed periods of admission and, in many cases, requires students to file applications to extend their stay with U.S. Citizenship and Immigration Services (USCIS).

For universities, Designated School Officials (DSOs), employers, immigration attorneys, and students, the key question is no longer simply “Is my OPT approved?” The new question is “Does my OPT fit within my authorized period of admission, or must I obtain an extension of stay?”

The Chicago immigration lawyers of Zneimer & Zneimer P.C. are carefully studying DHS’s July 17, 2026 Final Rule establishing fixed periods of admission and new extension procedures for F-1 students, J-1 exchange visitors, and I representatives of foreign information media. Throughout this series, we analyze the Final Rule section by section, explain DHS’s reasoning, and discuss the practical implications for students, universities, hospitals, employers, and immigration practitioners.

Before the Final Rule and How OPT Worked Under Duration of Status

To understand the significance of the Final Rule, it is important to understand how OPT has traditionally functioned.

Under the longstanding regulatory framework, an F-1 student admitted in Duration of Status (D/S) generally remained lawfully admitted for as long as the student:

• maintained valid F-1 status;
• pursued a full course of study unless otherwise authorized;
• complied with SEVIS reporting requirements;
• possessed a valid Form I-20;
• complied with employment restrictions; and
• timely obtained any required employment authorization.

When a student graduated and began post-completion OPT, the student’s lawful admission generally continued under the D/S framework. There was ordinarily no concern that the Form I-94 would expire during OPT because the admission itself was tied to the student’s status rather than to a fixed calendar date.

That framework has governed international education in the United States for decades.

DHS Did Not Eliminate OPT but It Changed the Immigration Structure Around It

The existing regulatory provisions authorizing:

• pre-completion OPT;
• post-completion OPT; and
• the 24-month STEM OPT extension

remain in place.

However, the DHS changed the admission mechanism.

The Final Rule separates two concepts that previously operated together:

1. Employment authorization, and
2. Authorized admission into the United States.

Those concepts frequently overlapped under Duration of Status.  Under the Final Rule, they may now expire on different dates. That distinction is likely to become one of the most important compliance issues facing international students.

What Actually Changes?

The Final Rule replaces admission in Duration of Status with a fixed period of admission.  Generally speaking, DHS provides an authorized period of admission that is tied to the student’s academic program, subject to the limits established in the regulation. For many students, that will result in an admission period of up to four years, while certain students—such as those falling within categories identified by the regulation – may receive a shorter admission period, generally up to two years. The exact period depends on the regulatory framework and the student’s circumstances rather than an automatic four-year grant in every case.

That distinction is critical.  Many discussions of the Final Rule incorrectly state that “all students receive four years.”That is not what the regulation provides. Instead, we must evaluate:

• the student’s program length;
• the applicable regulatory maximum;
• whether the student falls within a category receiving a shorter admission period; and
• any later extension or readmission.

The Five Dates Every OPT Student Must Monitor

Under the previous system, students often focused primarily on the expiration date of their Employment Authorization Document (EAD).The Final Rule requires students to monitor multiple independent deadlines, each serving a different legal purpose.

A student may possess a valid EAD while approaching the expiration of the authorized admission period.  Likewise, a student may have a valid Form I-20 but still require immigration action if the admission period expires before completion of OPT.  The Final Rule therefore requires students to view immigration compliance as a collection of related deadlines rather than a single expiration date.

Key Deadlines Under the Final Rule

The precise application of these deadlines depends on the student’s individual circumstances, but the following chart illustrates the framework established by the Final Rule.

Example 1: Traditional Four-Year Bachelor’s Degree

Consider the following example.

Student enters the United States: August 15, 2028

Bachelor’s program begins: August 20, 2028

Expected graduation: May 15, 2032

Post-completion OPT begins: May 16, 2032

Under the previous Duration of Status system, the student’s lawful admission generally continued while participating in authorized OPT.   Under the Final Rule, the analysis changes.

The student must determine:

• What is the expiration date shown on the Form I-94?
• Does OPT extend beyond that admission period?
• If so, when must an Extension of Stay application be filed?
• What happens if USCIS has not adjudicated the extension before the admission period expires?

Those questions simply did not arise for most students under Duration of Status.

Example 2: Ph.D. Student

Doctoral education demonstrates why the Final Rule has generated substantial discussion.  Assume a student begins a Ph.D. program expected to last five or six years. Research delays, dissertation revisions, laboratory work, grant funding, and publication requirements frequently extend the time necessary to complete the degree. Under the former framework, universities routinely extended the student’s program through SEVIS when academically justified. Under the Final Rule, the university’s academic approval may no longer be sufficient by itself.

If the student’s authorized admission expires before completion of the doctoral program or subsequent OPT, the student may also require an Extension of Stay from USCIS. For doctoral students, immigration planning should begin years and not months before anticipated completion.

Why DHS Adopted This Approach

The Final Rule explains that DHS believes fixed periods of admission provide greater opportunities for the government to verify continued eligibility, improve program oversight, reduce fraud, and strengthen immigration compliance.

The Department concluded that periodic review of an individual’s continued eligibility better serves the administration of the immigration laws than an open-ended admission based on Duration of Status.

Whether those policy judgments ultimately withstand judicial review remains to be seen. However, understanding DHS’s rationale is important because it explains why the agency chose to alter a system that had governed F-1 students for decades.

Practice Pointers

Students should calendar the expiration date on the Form I-94 as carefully as they monitor the expiration date on the EAD. Universities should revise OPT advising materials to emphasize that employment authorization and authorized admission are no longer synonymous. Employers should understand that a student’s immigration planning may involve additional filings unrelated to the validity of the Employment Authorization Document.

Immigration attorneys should review anticipated graduation dates years in advance for students enrolled in lengthy academic programs, particularly doctoral candidates and STEM students likely to pursue extended practical training.

Conclusion

The Department of Homeland Security did not eliminate Optional Practical Training. Instead, it fundamentally changed the immigration framework within which OPT operates. The shift from Duration of Status to fixed periods of admission means that students, universities, employers, and immigration attorneys must now evaluate multiple deadlines simultaneously and understand how authorized admission, employment authorization, and academic progress interact.

For many students, the most important question will no longer be whether OPT has been approved, but whether their authorized period of admission extends long enough to complete that practical training—or whether additional action with USCIS will be required.
