OPT vs. the STEM OPT Extension: What Changes After the First Year

By /

Last reviewed September 2026

Overview: The STEM extension adds up to 24 additional months of employment authorization on top of standard 12-month OPT, but requires a qualifying STEM degree, an E-Verify-enrolled employer, and a formal training plan (Form I-983) with ongoing reporting. As of September 2026, it also sits inside the new fixed admission period framework, which changed how the extension gets filed but not the 24-month length itself or the underlying eligibility criteria.

Standard OPT recap

Standard post-completion OPT provides up to 12 months of employment authorization tied to the student's field of study, applied for through Form I-765 around the time of graduation.

STEM degree eligibility for the extension

The 24-month STEM extension is available to students whose qualifying degree falls on the Department of Homeland Security's STEM Classification of Instructional Programs (CIP) code list. This list is reviewed periodically and can change, so a degree that qualified in a prior year should be checked against the current list rather than assumed.

Employer requirements, including E-Verify

The employer sponsoring STEM OPT must be enrolled in E-Verify, and the position must be directly related to the STEM degree and involve a genuine employer-employee relationship with practical training obligations, not simply nominal employment.

The I-983 training plan and reporting obligations

STEM OPT requires Form I-983, a formal training plan describing goals, supervision, and self-assessments, signed by both the student and the employer, and periodically evaluated. Employers and students share reporting obligations to the school's designated school official, including notifying the school of material changes to employment.

What changed with the fixed admission period rule

The DHS rule ending duration of status, effective September 15, 2026, did not eliminate the STEM OPT extension or shorten its length. What it changed is the filing mechanics: after a transition window running through March 18, 2027, a student applying for STEM OPT generally needs to file Form I-539 for an extension of stay alongside Form I-765 for the STEM OPT employment authorization itself, rather than relying on an approved STEM OPT application to implicitly extend lawful status the way duration of status previously allowed. Existing 180-day automatic employment authorization extensions for timely filed STEM OPT extensions continue to apply, and DHS has said it may extend the March 18, 2027 transition deadline in six-month increments if needed.

Timing the extension application

STEM OPT extension applications must generally be filed while the standard 12-month OPT authorization is still valid, before it expires. Students should now also confirm their I-94 expiration date and whether an I-539 extension of stay is required alongside the I-765, rather than assuming continued status automatically follows an approved application.

What happens if the employer or job changes during STEM OPT

A change of employer during STEM OPT generally requires a new Form I-983 training plan with the new employer and prompt notification to the school. An employer that is not enrolled in E-Verify, or a role that no longer genuinely relates to the STEM field, can jeopardize continued eligibility regardless of how much time remains on the extension.
