Final Oral Exam Impact on I-20 Program End Date

For graduate students with a final oral exam, your I-20 Program End Date is determined by:

  • The term in which your final oral exam is scheduled

AND

  • The final term in which you were required to enroll

 

By default, your I-20 Program End Date will end on the last day of your final semester of required enrollment. Your I-20 Program End Date is important, as it determines your eligibility for:

  • On-campus employment authorization
  • Curricular Practical Training (CPT) authorization
  • When you become eligible to apply for or start Optional Practical Training (OPT)
  • How long you can remain in the United States before departing after program completion.

 

Please note: Your I-20 Program End Date may be different than your graduation term with the university. The Graduate College establishes separate deadline for applying for graduation.

Defense Date Examples

Defense Date in Middle of Semester

It is most common that your defense date is in the middle of an academic semester. In that case, your I-20 Program End Date will be the final day of that term.

  • Spring 2026: If your defense is scheduled between January 20 - May 15 - your I-20 Program End Date would be May 15, 2026
  • Summer 2026: If your defense is scheduled for May 18 - August 7 - your I-20 Program End Date would be August 7, 2026
  • Fall 2026: If your defense is scheduled for August 24 - December 18 - your I-20 Program End Date would be December 18, 2026

Defense Date in Interim Period between Two Terms

If your defense is scheduled during "interim" period between two terms, when no classes are in session - then your I-20 Program End Date will be shortened to the end of the previous term.

  • Summer 2026: If your defense is scheduled between August 10-21 - your I-20 Program End Date would be August 7, 2026
  • Fall 2026: If your defense is scheduled between December 21 - January 15 - your I-20 Program End Date would be December 18, 2026

Exception: Defense on First Day of Fall/Spring or First Week of Summer

Based on Graduate College enrollment policy, exceptions may exist for defense dates that occur on the first day of the fall/spring semester, or during the first week of summer. In these scenarios, the student has the following choice:

  • The student can choose to enroll that semester, and their I-20 Program End Date can extend through the end of that term.
  • The student can choose to not enroll in that semester, and their I-20 Program End Date will be shortened to the end of the previous term.

 

You can also select to have your I-20 program end date end on your oral defense date, as long as the defense will take place during the semester. You can request your I-20 end on your defense date when completing the Optional Practical Training form in CyStart. Your oral defense date needs to be listed in AccessPlus.

I-20 Program End Date Shortened to Exact Date of Defense

A student has the option of shortening their I-20 Program End Date to the exact date of their defense, only if it falls within a spring, summer, or fall term.

  • This is typically only done when a student wants their Optional Practical Training (OPT) authorization to start in the middle of the semester.
  • The student's on-campus employment authorization or any CPT authorization will also be shortened to the exact date of their defense.
  • For a student with a graduate assistantship appointment, they will want to consult their assistantship provider to determine if shortening their position will impact their eligibility for assistantship benefits (tuition scholarship, health insurance coverage, etc.).

Impacts of I-20 Program End Date

On-Campus Employment End Date

All on-campus employment must end on or before your I-20 Program End Date. If your I-20 Program End Date is shortened, your on-campus job supervisor will be notified that your position must be shortened in Workday.

CPT Authorization End Date

All CPT authorization(s) must end on or before your I-20 Program End Date. If your I-20 Program End Date is shortened, you must inform your CPT employers of your amended work authorization dates.

OPT Authorization Start Date

A Post-Completion OPT authorization can only begin after a student's I-20 Program End Date. A student planning to apply for OPT will want to consider this timeline carefully. The OPT application process can take 2-4 months, so students are encouraged to start their application with ISSO as soon as they are able (up to 90 days before their I-20 Program End Date).

University Graduation

Iowa State University's policies and deadlines around graduation are administrative and do not impact your F-1 status. You cannot extend your immigration status in the United States for the sole reason of attending a graduation ceremony. Please review this Graduate College Important Deadlines resource that outlines Academic Plan, defense, and graduation deadlines. Further Graduate College policies can be found in the Graduate College Handbook.

Options After Program Completion

After your I-20 Program End Date, you have a 60-day grace period to determine your next course of action. By the end of the grace period, you must have either: 

  • Extended your F-1 immigration status by:
  • Ended your F-1 immigration status by:
    • Departing the United States
    • Working with an immigration attorney to otherwise apply to change your immigration status within the U.S.

Cancelling Defense

If you have cancelled or rescheduled your defense date to a future term, please contact ISSO or your assigned International Student Advisor about your I-20 Program End Date options.
