For many international students studying science or technology in the United States, the STEM OPT extension is one of the most important opportunities to build a long-term career. After completing their degree and the standard work authorization period, students often ask: What is STEM OPT? What is STEM OPT extension, and how can they use it to continue working in the U.S.?
The Optional Practical Training (OPT) program already allows international graduates to work in the U.S. for a limited period. But for STEM graduates—students with degrees in science, technology, engineering, or mathematics—the government offers an additional extension that significantly increases their work authorization.
According to the U.S. Department of Homeland Security, the 24-month STEM OPT extension allows qualified graduates to remain employed in the United States for up to 36 months total, combining the standard OPT period with the extension.

This extended work authorization helps students gain valuable industry experience and increases their chances of obtaining long-term employment or an H-1B work visa.
1. What Is STEM OPT and What Does the STEM OPT Extension Mean?
STEM OPT refers to a 24-month extension of Optional Practical Training (OPT) available to international students with qualifying STEM degrees who want to continue working in the United States after completing their standard OPT period.
The F1 visa OPT program allows students with F-1 visas to gain work experience in the United States after graduation. Standard OPT lasts 12 months. However, STEM graduates can extend this work authorization.
Relationship Between OPT and STEM OPT
The STEM OPT extension is not a separate program. Instead, it builds on the standard OPT period. Work authorization timeline typically looks like this: post-completion OPT – 12 months; STEM OPT extension – additional 24 months. Total possible work authorization: Up to 36 months.
Comparison Table: CPT vs. OPT vs. STEM OPT
| Feature | CPT (Curricular Practical Training) | OPT (Optional Practical Training) | STEM OPT Extension |
|---|---|---|---|
| Timing | During the degree program | Before (Pre-completion) or After (Post-completion) graduation | After completion of the 12-month Post-completion OPT |
| Eligibility | Required by the curriculum or for academic credit | All majors related to the field of study | Specific STEM majors on the DHS list |
| Max Duration | No set limit, but 12+ months full-time CPT cancels OPT eligibility | 12 months total per degree level | Additional 24 months (36 months total with initial OPT) |
| Approval By | University DSO (Designated School Official) | USCIS (requires EAD card) | USCIS |
| Job Offer | Required to apply | Not required at time of application | Required; must be an E-Verify employer |
| Fees | None | $410–$520 (varies by filing method) | Same as standard OPT |
| Unemployment | Not applicable | 90-day limit (post-completion) | 150-day cumulative limit |
2. What Is STEM OPT Extension and How Does It Work?
The STEM OPT extension allows eligible students to extend their U.S. work authorization by 24 months beyond standard OPT. Students first complete the standard Optional Practical Training (OPT) period. Before the 12-month OPT expires, eligible STEM graduates can apply for the extension. If approved, they receive an additional two years of work authorization.
Employer Participation Requirements
A major rule of the extension is the E-Verify employer requirement. Employers must participate in the E-Verify system, which confirms employee work eligibility. Without this participation, students cannot apply for the extension.
Training Plan Requirement
Students must complete Form I-983, which outlines: Training goals, Job responsibilities, Skill development plans. This ensures the job provides educational value.
3. STEM OPT Extension Eligibility Requirements
Not all international students qualify for the STEM OPT extension. Several eligibility requirements must be met.
- F-1 Visa Status: Applicants must hold a valid F-1 student status.
- STEM Degree Requirement: The student must graduate from a program listed in the STEM-designated degree program list (e.g., Computer science, Mechanical engineering, Mathematics, Data analytics).
- Employer Requirements: Employers must participate in E-Verify and provide structured training through Form I-983.
- Job Relation to Degree: The job must directly relate to the student's field of study.
- Application Timing: Students must apply before their initial OPT period expires (typically within 90 days before OPT expiration).
4. STEM OPT Extension Application Process
Applying for the STEM OPT extension requires careful planning.
- Step 1: Speak With Your Designated School Official — The DSO verifies eligibility and updates the student's SEVIS record.
- Step 2: Complete the Training Plan — Students and employers jointly complete Form I-983.

- Step 5: Receive the Employment Authorization Document — If approved, students receive an updated EAD card.
- Step 6: Continue Working While the Application Is Pending — Students can often continue working while their extension application is being processed.
5. What Happens If STEM OPT Is Denied?
If a STEM OPT extension is denied, the student typically loses the opportunity to extend their work authorization beyond the original OPT period. Understanding what happens if STEM OPT is denied is important for international students.
Common Reasons for Denial
- Employer Not Eligible: If the employer does not meet the E-Verify requirement, the application may be rejected.
- Incomplete Documentation: Missing documents or incorrect forms may result in denial.
- Job Not Related to Degree: Students must demonstrate that their job relates to their STEM degree.
- Application Timing Errors: Submitting the application after OPT expiration can lead to rejection.
Consequences of STEM OPT Denial
If the extension is denied, students may lose work authorization. They may need to: Leave the United States, Change visa status, Enroll in another academic program. After OPT expiration, students usually have a 60-day grace period to plan their next steps.

- Late Filing (Missing the 60-Day Window): You must file your I-765 with USCIS within 60 days of your DSO recommending the extension in SEVIS.
- Unclear Job-Degree Connection: You must be able to explain exactly how your job duties relate to your STEM degree.
- Missed 6-Month Reporting: Once approved, you must "check in" with your DSO every 6 months to confirm your address and employment.
