The STEM OPT Extension Explained

The STEM OPT extension lets certain F-1 students with a qualifying science, technology, engineering, or math (STEM) degree work an extra 24 months beyond standard post-completion Optional Practical Training (OPT) — but only for an employer enrolled and actively participating in E-Verify, and only after both the student and employer file a formal training plan called Form I-983. That brings total OPT work authorization for eligible students to up to 36 months (12 months of standard OPT plus the 24-month STEM extension). Because eligibility rules, the list of qualifying degrees, and reporting mechanics can change, always confirm current details with your school's Designated School Official (DSO) and USCIS before you rely on anything below.

Who can apply

To qualify for the 24-month STEM OPT extension, a student generally must:

• Currently be in a valid period of post-completion OPT in F-1 status;
• Have earned a bachelor's, master's, or doctoral degree in a field on the Department of Homeland Security (DHS) STEM Designated Degree Program List, from a school that is accredited and certified by the Student and Exchange Visitor Program (SEVP);
• Have a job offer, or already be working, at least 20 hours per week for an employer that is enrolled in and actively using E-Verify; and
• Have work that is directly related to the STEM degree that qualifies the student for the extension.

A student can also sometimes qualify using an earlier STEM degree — for example, someone finishing a non-STEM master's degree may be able to use a prior STEM bachelor's degree — but that prior degree generally must have been earned within the last 10 years, from an accredited, SEVP-certified school, and must not already have been used for a previous STEM OPT extension.

A student may use the STEM OPT extension at most twice in a lifetime, and a second use must be based on a degree at a higher academic level than the one used the first time. Because the qualifying-fields list (organized by Department of Education CIP codes) is periodically updated, confirm that your specific major is currently listed on the DHS STEM Designated Degree Program List through your DSO or the ICE/Study in the States website before assuming you qualify.

The E-Verify employer requirement

This is one of the most common points of confusion — and of failed applications. The employer must be enrolled in E-Verify and actually using the system, not merely registered or "in the process" of enrolling. Before applying:

• Ask the employer's HR department for the company's E-Verify Company Identification Number, which is entered on Form I-983;
• Independently confirm the employer's status through USCIS's E-Verify employer search tool at e-verify.uscis.gov; and
• Be cautious with small companies, startups, or nonprofits that say they are "E-Verify employers" but turn out not to be actively enrolled — an application built around an ineligible employer can be denied.

If the employer is a staffing or consulting agency placing the student at a third-party worksite, additional rules apply about who signs the I-983 and how supervision and training are documented; ask the DSO about this specific situation.

Form I-983: the training plan

Form I-983, Training Plan for STEM OPT Students, is completed jointly by the student and the employer before the DSO can recommend the STEM extension in the school's system. The form must:

• Identify specific goals for the training opportunity — the knowledge, skills, or techniques the student will gain;
• Explain how those goals connect to the student's STEM degree and how the employer's work-based learning opportunity will achieve them;
• Describe how the employer will supervise and evaluate the student's performance; and
• Be signed by both the student and an authorized official of the employer, who is attesting that the information is accurate.

Employers cannot simply sign off on a boilerplate description of "the job." USCIS and SEVP have denied or terminated STEM OPT authorizations where the training plan did not genuinely connect to the STEM field or where the employer could not demonstrate real supervision and training. If there is a material change later — a new employer, a new work site, a reduction in hours, or a significant change in job duties — an amended Form I-983 generally must be filed, and the change reported to the DSO within the required window (see below).

How and when to file

The application to USCIS (currently Form I-765, Application for Employment Authorization, with the DSO's STEM OPT recommendation entered in the student's SEVIS record) must be filed within the final 90 days before the current post-completion OPT authorization expires. Filing outside that window is a common, costly mistake. Because filing procedures, required fees, and current form editions change, confirm the exact form, fee, and mailing or online-filing instructions directly on uscis.gov before submitting anything.

If the STEM OPT application is filed before the current OPT expires and remains pending, work authorization and F-1 status generally continue automatically under a limited extension while USCIS adjudicates the case — but the rules around this "bridge" period are technical. Confirm current status-maintenance rules with your DSO rather than assuming continued work authorization.

Reporting duties while on STEM OPT — mark these deadlines

STEM OPT comes with reporting obligations that are stricter than standard OPT, and missing them can lead to automatic termination of the student's SEVIS record.

• 10-day reporting: Students generally must report any change in legal name, home address, employer, or loss of employment to the DSO within 10 days of the change.
• Periodic validation reports: Students are typically required to confirm their employment and contact information at set points during the 24-month extension — commonly at the 6-, 12-, 18-, and 24-month marks — submitted through the SEVP Portal or to the DSO. Confirm the exact schedule and submission method with your DSO, since SEVIS reporting mechanics have changed over time.
• Self-evaluations under Form I-983: The student and employer typically complete an evaluation of the student's progress toward the training goals partway through the STEM OPT period, and a final evaluation at the end, both of which the DSO must receive.

Separately, unemployment while on OPT is capped. Standard post-completion OPT allows a limited number of unemployment days, and the STEM extension adds additional unemployment days on top of that limit, for a combined cap across the full OPT-plus-STEM period. The days are cumulative (not reset), counted from the start date on the Employment Authorization Document, and exceeding the limit can result in termination of F-1 status. Confirm the current cumulative limit with your DSO or on studyinthestates.dhs.gov, since the exact figures are policy details that can be updated.

What to do — step by step

1. Confirm your degree is currently on the DHS STEM Designated Degree Program List with your DSO.
2. Secure a qualifying job or job offer (at least 20 hours/week, directly related to your STEM field) with an employer you have independently confirmed is enrolled and active in E-Verify.
3. Complete Form I-983 jointly with the employer, with signatures from both sides.
4. Ask your DSO to recommend the STEM OPT extension in SEVIS and issue an updated Form I-20.
5. File the current USCIS application within the required window before your existing OPT authorization expires — verify the exact form, fee, and deadline on uscis.gov.
6. Calendar every reporting deadline (10-day change reports, periodic validation reports, and I-983 self-evaluations) as soon as your extension is approved.
7. If you change jobs, lose your job, or your duties materially change, report it within the required window and update Form I-983 as needed — do not wait.

For background on the F-1 student visa itself — admission, maintaining status, and the standard 12-month OPT period that precedes the STEM extension — see our overview of student visas. Reporting failures under STEM OPT can jeopardize F-1 status generally, so understanding the underlying student-status rules matters even after graduation.

Common mistakes to avoid

• Assuming an employer is "E-Verify eligible" without confirming actual, active enrollment through the official employer search.
• Treating Form I-983 as paperwork rather than a real training plan — vague or copy-pasted plans invite scrutiny.
• Missing the 90-day filing window before current OPT expires.
• Forgetting periodic validation reports or the 10-day change-reporting deadline, which can trigger automatic SEVIS termination.
• Not updating Form I-983 and notifying the DSO promptly after a job change, since the STEM extension is tied to the specific employer and training plan on file.

Beware of fraud

Only your school's DSO, USCIS, or a licensed immigration attorney or DOJ-accredited representative can give you reliable guidance on STEM OPT eligibility and filings. Be wary of anyone — including some unlicensed "consultants" or notarios — who promises guaranteed approval, offers to backdate or falsify a Form I-983, or claims they can get you around the E-Verify requirement. Submitting false information on an immigration form can result in denial, SEVIS termination, and future immigration consequences.
