If you’re an F-1 student finishing a STEM degree, the 24-month STEM OPT extension is what turns a single year of US work authorization into up to three — and it’s also one of the most document-heavy processes in the F-1 system. Miss the I-983 or the filing window and you can lose work authorization entirely. Here’s exactly what’s required in 2026.
What the STEM OPT extension is
Standard Optional Practical Training (OPT) gives F-1 graduates 12 months of work authorization in their field of study. Students who completed a qualifying STEM (science, technology, engineering, or mathematics) degree can apply for an additional 24-month extension, adjudicated by U.S. Citizenship and Immigration Services (USCIS), bringing total practical training to up to 36 months (USCIS Policy Manual, Volume 2, Part F, Chapter 5). This is a different track from Curricular Practical Training (CPT) — see our OPT vs CPT guide if you’re not sure which applies to you.
Who qualifies
- Your degree — the one on which you’re basing the extension — must be on the DHS STEM Designated Degree Program List (this can be your current degree or a prior eligible STEM degree from the same institution, in some cases).
- You must currently be on a valid period of standard post-completion OPT.
- Your prospective employer must be enrolled in E-Verify.
- The job must be a real, paid, bona fide employer-employee relationship — at least 20 hours per week — directly related to your STEM field of study.
The E-Verify requirement
Your employer must be enrolled in E-Verify and must provide their E-Verify Company Identification Number on your Form I-983. This is a hard eligibility gate: if your employer isn’t enrolled and won’t enroll, you cannot use that job offer to support a STEM OPT extension, no matter how relevant the role is to your degree.
Form I-983: the Training Plan
Form I-983 is what distinguishes STEM OPT from ordinary OPT. It is completed and signed jointly by you and your employer, and — importantly — it is submitted to your school’s Designated School Official (DSO), not to USCIS. In it, your employer attests that:
- They have adequate resources and trained personnel to properly train you;
- You will not be displacing a full-time, part-time, temporary, or permanent US worker; and
- The role will genuinely help you meet the learning objectives you and your employer define.
You must have your DSO issue a STEM-recommended Form I-20 reflecting the I-983 before you file your extension application with USCIS.
Filing timeline
- File at least 90 days before your current OPT EAD expires. Filing as early as possible within that window reduces the risk of a work-authorization gap.
- The 180-day automatic extension. If you file on time and your current EAD expires while the extension is still pending, you receive an automatic 180-day extension of work authorization while USCIS adjudicates the case.
- Processing times in 2026. Standard processing commonly runs 3–5 months depending on service center backlogs; premium processing (where available for this category) targets a much faster turnaround, but check current USCIS processing time data for your service center before assuming either figure applies to your case.
Ongoing reporting obligations — don’t skip these
STEM OPT comes with compliance requirements that standard OPT doesn’t:
- 12-month and 24-month evaluations, completed jointly by you and your employer, assessing progress against the I-983 learning objectives.
- Self-evaluations at the same intervals (and at the end of the STEM OPT period).
- All of these go to your DSO, not USCIS, and are kept in your school’s SEVIS record — but missing them can jeopardize your status, so calendar the deadlines the moment your extension is approved.
- Material changes — a new employer, a significant change in job duties, or an interruption of more than 5 months of unemployment during the STEM OPT period — must be reported to your DSO promptly.
Common mistakes that cost students their extension
- Filing after the 90-day window closes, leaving no runway if USCIS requests more evidence.
- Using an employer not enrolled in E-Verify, discovered only after an offer is signed.
- Vague or copy-pasted I-983 learning objectives that don’t genuinely tie to the STEM degree.
- Missing the 12-month evaluation deadline, which can be treated as a status violation.
- Exceeding 150 cumulative days of unemployment across the full OPT + STEM OPT period (the standard OPT unemployment cap carries through the extension).
FAQ
Can I start a new job before my STEM OPT extension is approved? No — you must wait for approval (or rely on the 180-day automatic extension only if your prior EAD was still valid and the extension was filed on time) before beginning employment under the new authorization.
Does STEM OPT count toward the H-1B cap-gap? Yes — students transitioning to an H-1B can use cap-gap protection if their H-1B petition is filed while OPT/STEM OPT is still valid, extending work authorization until the H-1B start date.
Can I change employers during STEM OPT? Yes, but the new employer must also be E-Verify enrolled, and a new I-983 must be completed and submitted to your DSO for the new employer.
What happens if my STEM degree isn’t on the DHS list? You aren’t eligible for the extension based on that degree — check the current DHS STEM Designated Degree Program List, as it’s updated periodically and may include degrees not obviously coded as “STEM.”
