STEM OPT Extension: Eligibility, Application, and Rules
The STEM OPT Extension allows eligible F-1 international students with STEM degrees to work in the U.S. for an additional 24 months after their initial OPT period. This extension offers a crucial pathway to gain advanced practical experience and bridge toward H-1B or long-term status.
For international students in the U.S. on an F-1 visa, Optional Practical Training (OPT) offers a one-year opportunity to work in their field. But for STEM graduates, there's more time available.
The STEM OPT Extension adds 24 extra months of work authorization — making it a total of 36 months of on-the-job experience in the U.S. This time is often used to secure H-1B sponsorship or plan for a future green card.
To qualify, students must meet strict eligibility criteria, including a qualifying STEM degree and a U.S. employer enrolled in E-Verify. The process also requires a formal training plan and compliance with ongoing reporting rules.
If you're nearing the end of your initial OPT period, applying for the STEM extension on time is essential to maintain your work authorization and status.
What Is STEM OPT and Who Qualifies?
The STEM OPT Extension is a 24-month extension of post-completion OPT for F-1 students who earned a U.S. degree in an eligible STEM (Science, Technology, Engineering, or Math) field.
To qualify, students must be in valid F-1 status and currently on active post-completion OPT. They also need a qualifying STEM degree from a DHS-certified school and a job offer from an E-Verify–enrolled employer.
🔹 You may be eligible if:
Your degree is on the DHS STEM Designated Degree Program List
You're currently in your initial 12-month OPT period
Your employer is enrolled in the E-Verify system
You can submit a completed Form I-983 Training Plan
📌 Good to know:
You can apply based on your most recent STEM degree or a previously earned eligible STEM degree, as long as it’s from a U.S. institution.
For a full list of qualifying programs, refer to the DHS STEM degree list.
Eligibility Criteria for the 24-Month STEM OPT Extension
To qualify for the STEM OPT extension, F-1 students must meet all of USCIS’s specific requirements. Missing even one may lead to a denial or rejection.
🔹 Key Eligibility Requirements:
Must be in valid F-1 status with active post-completion OPT
Hold a degree in a DHS-approved STEM field (bachelor’s or higher)

🔸 Additional Conditions:
Work must be paid, full-time (20+ hours/week)
Employment must be directly related to your STEM degree
You cannot be self-employed or work for staffing agencies
📌 Tip:
If you previously earned a STEM degree (from a U.S. school) but are on OPT for a non-STEM degree, you may still qualify — this is known as the previous degree rule, but it has extra conditions.

What Kind of Work Is Allowed on STEM OPT?

Unpaid internships or volunteering
📌 Tip:
You must report all employment changes within 10 days through your school's SEVP Portal. If you're unemployed for more than 150 total days across OPT + STEM OPT, you may violate status.

🔸 Employer Compliance:

📌 Tip:

Conclusion: What to Keep in Mind After You Apply
The STEM OPT extension gives international students in technical fields a valuable 24-month opportunity to gain more U.S. work experience. But with that opportunity comes added responsibility and careful planning.
Be sure to apply on time, keep your employer and training plan compliant, and report any changes quickly. Always keep backup copies of your I-983, EAD card, and validation reports for future visa or green card filings.
If you plan to move to an H-1B visa or apply for a green card, the STEM OPT period can be a useful bridge — but you’ll need to start early and stay aware of travel, timing, and employer eligibility.
