OPT Work Experience Requirements (Regulations & Rules)

What OPT Work Experience Requirements Actually Measure

Optional Practical Training (OPT) is not an open work authorization for any employment after graduation. The regulation — 8 CFR 214.2(f)(10)(ii)(C) — limits OPT to work that "directly relates" to the student's major field of study. That direct relationship is the core requirement, and it is measured through job duties documented in writing, not inferred from a job title, employer name, or the student's subjective judgment. A computer science graduate cannot approve their own employment at a tech company — USCIS can request evidence that the specific tasks performed in that position apply the classroom training the degree provided.

The F-1 student visa category exists to enable study in the United States, and OPT is a temporary extension that allows students to apply their education in a practical setting before returning home or transitioning to another visa status. The work-relevance test enforces the distinction between training and general employment. Students who file Form I-765 for OPT receive an Employment Authorization Document (EAD) valid for twelve months after degree completion (or longer for STEM OPT Extension). That period must be used for work that meets the regulatory standard — and if it is not, the student risks falling out of status.

Here's the honest answer: USCIS does not publish a list of approved job titles or industries for each degree. The relevance determination is case-specific, and the burden of documenting the connection is on the student and the employer. What matters is whether the day-to-day duties of the position require knowledge and skills the degree conferred, demonstrated through an offer letter, employment contract, or supervisor statement that details tasks, not through a resume that generalizes.

The Direct Relationship Test — What USCIS Evaluates

USCIS applies the direct relationship test through these factors, drawn from 8 CFR 214.2(f)(10)(ii)(C)(2):

• The duties of the position. The student must provide documentation stating what tasks the job requires — software development, data analysis, laboratory procedures, engineering calculations, financial modeling. General descriptions like "support company operations" or "contribute to team success" do not establish the connection.
• The degree field. The student's major area of study on Form I-20 is the baseline. A marketing major cannot claim relevance for a research scientist position, even if the employer hired them. The test is whether the coursework prepared the student for the specific duties they will perform.
• Whether the position advances the student's professional development. OPT must train the student in their field, not merely employ them. A position that uses zero skills from the degree — even if it is in a related industry — fails this test.

The regulation does not require full-time employment. Part-time work, multiple part-time positions, and contract work all qualify, as long as each position meets the direct relationship standard. What the regulation prohibits is unemployment beyond the allowed limits: students on post-completion OPT may not be unemployed for more than ninety days total during the twelve-month authorization period. Days of unemployment begin accumulating the day after OPT start date and count every day the student is not engaged in qualifying employment or unpaid training directly related to the major.

OPT Categories and Their Work Requirements

The bottom line: pre-completion OPT allows students to gain experience while still enrolled, but it is rarely the sole work authorization students rely on. Post-completion OPT is the primary period, and STEM OPT extends it by 24 months for students with degrees in science, technology, engineering, or mathematics fields designated on the STEM Designated Degree Program List maintained by the Department of Homeland Security. That extension carries stricter employment requirements — the employer must participate in E-Verify, and the student and employer must complete Form I-983, which documents a formal training plan reviewed every six months.

What Counts as Qualifying OPT Employment

Qualifying employment includes:

• Paid employment in a position directly related to the major, whether W-2 or 1099 (contractor status does not disqualify the work, but the duties still must meet the test)
• Unpaid training or internship with an established entity that provides practical experience in the field, documented through a formal agreement or letter — not self-declared volunteer work
• Self-employment or business ownership, if the student can document that the work performed applies their degree training and the business is actively operating (a registered LLC with no activity does not count)

What does not count:

• Work outside the major field, even if the student accepted it due to financial need
• Unemployment days while searching for a qualifying position
• Work that began before the OPT start date on the EAD card
• Positions held after the EAD expiration date, even if the student has filed for another status (unless a gap provision applies)

The practical consequence: students must track their own unemployment days and maintain evidence of employment throughout the OPT period. USCIS does not send reminders when the ninety-day limit approaches, and exceeding it places the student out of status — a violation that can affect future visa petitions and green card applications.

Documentation OPT Participants Must Maintain

The student is responsible for proving that OPT employment met the requirements if USCIS requests evidence. Recommended documentation includes:

• Offer letters or employment contracts that describe job duties in specific terms
• Pay stubs, tax forms (W-2 or 1099), or bank statements showing regular payment for work performed
• Supervisor letters confirming the student's role, the tasks performed, and the relevance to the degree field
• For self-employment: business registration, client contracts, invoices, project descriptions, proof the business is operational
• For unpaid training: a signed agreement with the host organization describing the training plan, hours, and supervisor
• Start and end dates for every position held during the OPT period, plus records of any gap between positions

Students must also report changes to their Designated School Official (DSO) within ten days: change of employer, change of address, legal name change. Failure to report can result in SEVIS termination, which ends work authorization immediately.

STEM OPT Extension — Additional Requirements

Students with degrees on the STEM Designated Degree Program List may extend post-completion OPT by 24 months. This extension is not automatic; it requires:

• Filing Form I-765 with the "STEM OPT Extension" eligibility category before the initial twelve-month OPT period expires
• An employer that participates in E-Verify and signs Form I-983 (Training Plan for STEM OPT Students)
• A position that averages at least twenty hours per week (part-time positions below this threshold do not qualify for STEM extension)
• Reporting every six months to the DSO on whether the training plan objectives are being met

Form I-983 is submitted to the school, not to USCIS, but the student must retain a copy. The form details specific learning objectives tied to the degree field, formal training and evaluation methods, and supervisor oversight. USCIS may request the training plan during any review, and if the plan was not followed or the position no longer qualifies, the extension can be revoked. As of 2026, USCIS charges a filing fee for Form I-765; confirm the current amount on the USCIS fee schedule at uscis.gov/forms before submitting the extension application.

What If the Job Duties Change During OPT?

If the student's employer assigns new duties that no longer directly relate to the major, the position stops qualifying as OPT employment. The student does not lose their EAD, but the days spent in that role count as unemployment days toward the ninety-day limit. The student must either return to qualifying work or leave the position.

If the change in duties still relates to the major but in a different capacity — for example, a chemistry graduate moves from laboratory analysis to quality control in the same company — the work continues to qualify. The test is whether the new tasks still apply the degree training. The student should obtain a letter from the employer documenting the updated duties and keep it with their OPT records.

What If the Student Runs Out of Unemployment Days?

Exceeding the ninety-day unemployment limit (or 150 days total for STEM OPT) places the student out of status. There is no grace period and no process to restore the lost days. The student's SEVIS record is terminated, and they are no longer authorized to work or remain in the United States under F-1 status.

Options at that point are limited. The student may:

• Depart the United States immediately before the status violation accrues additional consequences
• File for reinstatement to F-1 status if they can prove the violation was due to circumstances beyond their control and they have not been out of status for more than five months — this is a narrow exception with no guarantee of approval
• Apply for a change of status to another visa category (such as H-1B if an employer sponsors them), but the status violation will appear in the record and can complicate adjudication

Prevention is the only reliable strategy. Students should begin the job search well before the OPT start date, accept temporary or contract work if permanent positions are not immediately available, and document employment continuously.

What If the Student Works for a Startup or Small Company?

OPT does not require the employer to be a large corporation or a household name. Startups, small businesses, and newly formed companies all qualify, as long as the position meets the direct relationship test. The student must be able to prove the business is legitimate and operational — state business registration, a physical or virtual office, client or customer records, and an employer who can provide verification of employment.

Self-employment through a startup the student founded also qualifies, provided the student documents that the business is actively engaged in work related to their major. A computer science graduate who builds software for clients and maintains records of contracts, invoices, and deliverables meets the requirement. A business administration graduate who registers an LLC but performs no actual business activity does not.

How OPT Fits Into Broader Immigration Planning

OPT is a bridge, not a permanent solution. Most students use the twelve-month (or 36-month with STEM extension) period to gain U.S. work experience, establish professional relationships, and position themselves for employer sponsorship of an H-1B visa or another long-term status. The OPT period is also when students typically begin consulting immigration attorneys about green card pathways, particularly employment-based categories like EB-2 or EB-3.

The H-1B visa has an annual cap, and the registration window opens in March each year for positions starting in October. Students on OPT who intend to stay in the United States long-term should plan around that timeline. If the H-1B petition is approved, the student can transition directly from OPT to H-1B status without leaving the country. If the petition is denied or not selected in the lottery, the student must either depart when OPT expires or find another qualifying status.

For students from countries with long green card backlogs (India and China for employment-based categories), OPT may be the first step in a decade-long process. Starting that process with accurate documentation and clean status history is critical. A $250 consultation can clarify what the regulatory requirements mean for your specific degree, job offer, and long-term goals.
