Under federal immigration regulations (8 CFR § 214.2(f)(10)(ii)(C)), international students holding an F-1 visa who graduate with a designated Science, Technology, Engineering, or Math (STEM) degree from an accredited U.S. institution are eligible to apply for a 24-month STEM OPT extension. Combined with the initial 12 months of standard post-completion Optional Practical Training (OPT), this policy provides a total of 36 continuous months (3 full years) of lawful full-time employment authorization in the United States without requiring immediate H-1B visa lottery sponsorship.

Key Takeaways from the AcademicZed Immigration Compliance Desk
- CIP Code Verification: Eligibility is determined entirely by the 6-digit Classification of Instructional Programs (CIP) code printed on page 1 of your Form I-20, which must match the official DHS STEM Designated Degree Program List.
- Mandatory E-Verify Employer: Unlike initial OPT where any legitimate US employer qualifies, STEM OPT employers must be enrolled in the federal E-Verify program and possess an active E-Verify company ID number.
- Form I-983 Formal Training Plan: The student and employer must execute a formal, comprehensive Form I-983 establishing specific training objectives, performance evaluations, and direct supervisor oversight.
- 180-Day Automatic Work Authorization Extension: As long as USCIS receives your Form I-765 before your initial 12-month OPT EAD card expires, your work authorization is automatically extended for up to 180 days while your STEM application is pending adjudication.
Comparison Matrix: Standard 12-Month OPT vs. 24-Month STEM OPT Extension
The table below summarizes the key legal, employment, and reporting differences between both stages of practical training:
| Dimension | Standard Initial OPT (12 Months) | STEM OPT Extension (24 Months) |
|---|---|---|
| Eligible Majors | All accredited academic degrees | Strictly DHS STEM CIP Codes |
| Employer Requirements | Any legitimate employer; E-Verify optional | Must be enrolled in federal E-Verify |
| Unemployment Days Allowed | Up to 90 cumulative days | 60 additional days (150 days total) |
| Training Plan Form | Not required | Mandatory Form I-983 with 12 & 24 mo. reviews |
| Minimum Weekly Hours | At least 20 hours per week | At least 20 hours per week (paid role only) |
Step-by-Step STEM OPT Application Timeline
- 90 Days Before Expiration: The application window opens exactly 90 days before the expiration date printed on your current initial OPT EAD card.
- Execute Form I-983: Complete all sections of the formal training plan alongside your supervisor and corporate HR department.
- Request STEM OPT I-20: Submit Form I-983 to your university Designated School Official (DSO) to receive an updated Form I-20 recommending the STEM extension.
- File Form I-765 Online: Submit your application via your USCIS online account within 60 days of the DSO recommendation date, uploading your passport, visa, STEM I-20, degree diploma, and paying the $470 filing fee.
Frequently Asked Questions (FAQs)
Can I work while my STEM OPT application is pending with USCIS?
Yes. If your Form I-765 is timely filed before your initial 12-month OPT EAD expires, 8 CFR § 274a.12(b)(6)(iv) grants an automatic 180-day extension of your employment authorization while USCIS processes your application.
Can I qualify for STEM OPT based on a prior U.S. degree?
Yes. If you currently hold a non-STEM master’s degree (e.g. an MBA) but previously earned a STEM bachelor’s degree from an accredited U.S. institution within the past 10 years, you may apply for STEM OPT based on that prior degree, provided your job directly relates to that STEM field.
Can self-employed or freelance workers qualify for STEM OPT?
No. Unlike initial OPT, STEM OPT explicitly prohibits self-employment, volunteer work, and standard 1099 independent contractor arrangements. You must have a bona fide employer-employee relationship with an E-Verify enrolled company that signs your Form I-983.
How many total days of unemployment are allowed across the 3 years?
Students receive 90 days of allowed unemployment during the initial 12-month OPT period, plus an additional 60 days upon approval of the STEM extension, giving a cumulative total of 150 allowable unemployment days over the entire 36 months.
How many times can an international student use STEM OPT in their lifetime?
An individual may receive a maximum of two STEM OPT extensions during their lifetime, provided that each extension is completed at a higher educational degree level (e.g. one after a Bachelor’s degree and a second after a Master’s or PhD).
