Form I-9 for OPT and STEM OPT: An Employer Checklist

Hiring an international graduate can leave HR with several documents and a practical question: What do we need to complete Form I-9 for an employee on OPT?

For many F-1 students working through Optional Practical Training, an unexpired Employment Authorization Document establishes both identity and employment authorization. But pending applications, STEM OPT extensions, and separate training-program obligations require additional attention.

The key is to separate three decisions: whether the person is authorized to start work, how to document that authorization on Form I-9, and what ongoing obligations apply to the employer.

Understand OPT before reviewing documents

OPT allows eligible F-1 students to obtain temporary employment directly related to their major area of study. It generally provides up to 12 months of authorization, subject to eligibility and program rules.

Eligible graduates in science, technology, engineering, or mathematics may qualify for a 24-month STEM OPT extension. That extension comes with additional employer requirements.

For onboarding purposes, distinguish these situations:

• Initial OPT: The student has applied for or received employment authorization from USCIS.
• STEM OPT extension: The student is seeking or has received an extension of qualifying post-completion OPT.
• Curricular Practical Training: CPT is a different authorization framework. Do not apply the OPT document workflow to every F-1 student.

An F-1 visa or student status alone does not establish authorization for an ordinary off-campus job. Likewise, a school recommendation for OPT is not the same as USCIS approval of an initial OPT application.

Complete Form I-9 using the normal deadlines

OPT employees follow the same basic Form I-9 completion deadlines as other employees.

The employee generally completes Section 1 no later than the first day of employment for pay. The employer generally completes Section 2 within three business days after that first day. For employment lasting fewer than three business days, Section 2 must be completed no later than the first day.

Do not treat the Section 2 completion window as permission to work without authorization. A student cannot start an OPT job merely because an application is pending or because HR plans to inspect documents later.

Review acceptable documents without demanding a specific one

An unexpired Employment Authorization Document, Form I-766, is a List A document. When presented and accepted, it establishes both identity and employment authorization; the employer should not also demand List B or List C documents.

Employees choose which acceptable documents to present. Do not make a particular document mandatory because someone is an international student or is perceived to be a noncitizen.

Review documents through an authorized examination method and determine whether they reasonably appear genuine and relate to the employee. Record the required information accurately, including the document expiration date.

A Social Security number is not, by itself, evidence of current employment authorization. Similarly, an initial OPT application receipt generally does not substitute for an approved EAD.

Separate I-9 evidence from OPT program records

Form I-9 compliance and participation in a student training program are related, but they are not interchangeable.

For example, accepting an unexpired EAD for Form I-9 does not independently establish that a particular job satisfies OPT's requirement that employment relate to the student's field of study.

Where additional information is needed for a legitimate program requirement, explain that purpose clearly. Do not characterize every supporting record as a required Form I-9 document.

A useful internal division is:

• HR or onboarding: Form I-9 completion and document review.
• Hiring manager: Job duties, supervision, and training commitments.
• Immigration program owner: Coordination on applicable OPT or STEM OPT requirements.
• Payroll: Accurate employment and payroll records.

For high-volume employers, Trak's Clear I-9 service can support a consistent verification workflow while the employer manages its separate training-program responsibilities.

Know when STEM OPT requires E-Verify

An employer does not have to enroll in E-Verify solely because it hires someone on ordinary OPT. Other federal, state, or contractual requirements may still apply.

STEM OPT is different: A participating employer must be enrolled in E-Verify and remain in good standing. The employer and student must also complete Form I-983, Training Plan for STEM OPT Students, and meet applicable program requirements.

Before committing to a STEM OPT arrangement, confirm:

• The employing entity meets the E-Verify requirement.
• The employer can provide the required training and supervision.
• The proposed position meets applicable STEM OPT conditions.
• Someone owns Form I-983 updates, evaluations, and required reporting.

An E-Verify case does not replace Form I-983, and a signed training plan does not replace Form I-9. Avoid assigning all three responsibilities to a manager who has not been trained on their differences.

Handle pending STEM OPT extensions carefully

A timely filed STEM OPT extension application can automatically extend employment authorization for up to 180 days while the application is pending. This is a specific rule—not a blanket extension for anyone who has filed an immigration application.

For Form I-9 purposes, USCIS provides a process involving the expired OPT EAD and a Form I-20 endorsed for the STEM OPT extension. HR should follow the current USCIS instructions for evaluating and recording that document combination.

Before relying on an extension:

1. Confirm that the circumstances qualify under the applicable rule.
2. Review the required supporting documents.
3. Calculate the extension period using current guidance.
4. Record the information as instructed.
5. Track the application outcome and the applicable authorization end date.

Do not automatically apply extension periods used for other EAD categories to an OPT employee. Other provisions, such as an applicable H-1B cap-gap extension, have their own eligibility and documentation rules.

Track reverification without over-requesting documents

OPT work authorization is temporary, so HR needs a reliable follow-up process. Set reminders early enough to resolve questions before the applicable authorization period ends.

When reverification is required, use Supplement B according to current Form I-9 instructions. The employee may present any acceptable List A or List C document establishing continued employment authorization; do not insist on another EAD simply because that was the original document.

Also distinguish an EAD's printed expiration date from a properly documented extension. An expired card does not necessarily mean authorization has ended, but a pending application does not necessarily mean authorization continues.

For the broader process, see our guide to when I-9 reverification is required.

Build a repeatable OPT onboarding process

A practical workflow should identify the authorization type, confirm the permissible start date, complete Form I-9, address any STEM OPT obligations, and assign follow-up ownership.

Before handling an unfamiliar extension or document combination, consult the current USCIS I-9 Central guidance and DHS resources at Study in the States. Requirements and agency instructions can change. Escalate uncertain cases to qualified immigration counsel rather than guessing or rejecting unfamiliar documents automatically.
