What Is Optional Practical Training (OPT)? A Guide for F-1 Students
Optional Practical Training (OPT) is temporary U.S. work authorization that lets eligible F-1 international students gain practical experience related to their major. It can take place before or after graduation, but students generally need approval from U.S. Citizenship and Immigration Services (USCIS) before starting work. Understanding the application timeline, job rules, unemployment limits, and possible STEM extension can help students protect their immigration status and plan a smoother transition from school to work.
What Is Optional Practical Training?
OPT is a form of employment authorization for certain students in F-1 nonimmigrant status. It allows them to work in a job directly related to their field of study, using knowledge gained in their academic program. OPT is not a separate visa or a change in immigration status: the student generally remains in F-1 status while participating.
USCIS adjudicates OPT applications and issues an Employment Authorization Document (EAD) when an application is approved. A student must have the EAD and may work only during the authorization dates printed on it. A recommendation from a school official is an important application step, but it is not itself permission to work.
OPT rules are governed by federal immigration regulations and administered through the student’s designated school official (DSO), USCIS, and the Student and Exchange Visitor Program (SEVP). Individual circumstances can affect eligibility and timing, so students should confirm their plans with their DSO and consult official government guidance.
Types of OPT
There are two main types of OPT: pre-completion OPT, used before the student completes the academic program, and post-completion OPT, used after completion. Eligible graduates in certain science, technology, engineering, and mathematics (STEM) fields may also apply for a 24-month STEM OPT extension.
| Type | When It Is Used | General Limits |
|---|---|---|
| Pre-completion OPT | Before completing the program | Part-time during the academic term; full-time may be possible during official school breaks or when coursework is complete and only a thesis or equivalent remains |
| Post-completion OPT | After completing the program | Usually up to 12 months of authorization for each higher education level, subject to eligibility and prior OPT use |
| STEM OPT extension | After an eligible period of post-completion OPT | An additional 24 months may be available for qualifying STEM graduates who meet program and employer requirements |
Part-time pre-completion OPT generally counts at half the rate of full-time OPT toward the available 12-month period. For example, a semester of authorized part-time OPT typically uses less of the limit than a semester of full-time OPT. A DSO can explain how a student’s previous authorizations affect the remaining eligibility.
Who Is Eligible for OPT?
In general, an applicant must be in valid F-1 status, have completed at least one full academic year of study at a U.S. college, university, conservatory, or seminary, and seek work related to the major area of study. Some programs may have specific requirements about when the academic year is completed. Students should ask their DSO to review their records before submitting an application.
OPT is generally available for one period of up to 12 months at each higher educational level. A student who completes a higher degree may qualify for a new period, subject to the rules. Previous full-time curricular practical training (CPT) totaling 12 months or more can make a student ineligible for OPT at that educational level. Part-time CPT does not have the same disqualifying effect, though all CPT history should be reviewed with the DSO.
Eligibility is not based only on having a job offer. A student may generally apply for post-completion OPT without an offer, but must still meet the filing deadlines and other requirements. Work performed during OPT must be directly related to the student’s major; a position that is unrelated, even if paid or prestigious, may not satisfy the rule.
How to Apply for OPT
- Discuss timing with the DSO. The DSO reviews eligibility, explains school procedures, and may recommend OPT in the Student and Exchange Visitor Information System (SEVIS).
- Receive an updated Form I-20. The student must obtain the OPT-recommended Form I-20 from the DSO and sign it as instructed.
- File Form I-765 with USCIS. The student applies for employment authorization, pays the required fee, and submits the requested supporting documents. USCIS instructions and fees can change, so applicants should use the current form edition and official filing guidance.
- Wait for USCIS authorization. A student should not begin working merely because the application has been filed or the DSO has made a recommendation.
- Start only when permitted. Work may begin only after the EAD is issued and the authorization start date has arrived, subject to any applicable regulatory exception.
For post-completion OPT, the application window generally opens up to 90 days before the program end date and closes 60 days after it. USCIS must receive Form I-765 no later than 30 days after the DSO enters the OPT recommendation in SEVIS, and the filing must also fall within the overall application window. These deadlines are separate; filing within one window does not automatically satisfy the others.
Because processing takes time and start dates are constrained, students should begin planning well before graduation. A late or incorrectly prepared application can reduce the time available to work or result in denial. The student’s DSO can provide school-specific steps, while USCIS’s Form I-765 page provides current filing instructions.
OPT Start Dates and Work Authorization
For post-completion OPT, a student selects a requested start date within the permitted period after the program end date. The date cannot be earlier than program completion, and it generally must fall within the 60-day grace period following completion. The requested date does not guarantee that authorization will begin then: the student must wait for USCIS approval and the EAD’s start date.
A student whose EAD arrives after the requested start date may lose some potential OPT time, because the authorization period is not simply extended to make up for processing delays. Students should consider this risk when choosing a start date and should avoid making employment commitments that depend on working before authorization begins.
Students with a timely filed STEM OPT extension application may have a temporary automatic extension of work authorization while USCIS processes the application, if they meet the applicable requirements. The rules and duration for this extension should be checked against current USCIS guidance; it does not apply automatically to every OPT application.
What Jobs Qualify During OPT?
OPT employment must be directly related to the student’s major field of study. The student should be able to explain the relationship between the duties and the academic program. For example, a computer science graduate might work in software development, while a biology graduate might work in a laboratory or a related research role. Job titles alone do not establish that a position qualifies.
During standard post-completion OPT, qualifying work can include paid employment, multiple employers, work for a staffing agency or consulting firm, self-employment, or an unpaid internship or volunteer position when the arrangement complies with applicable labor laws. A student should keep evidence of the work, its dates, hours, duties, and connection to the major. Unpaid work cannot be used to bypass minimum-wage or other employment protections.
Post-completion OPT generally requires at least 20 hours of qualifying work per week to count as employment under SEVP guidance. A student may have more than one qualifying job, but should ensure the combined work meets the requirement and remains related to the major. Pre-completion OPT has different hour limits during academic terms and breaks.
Unemployment Limits and Reporting
Students on post-completion OPT may accrue no more than 90 days of unemployment during the initial OPT period. Students approved for the 24-month STEM extension may accrue no more than 150 days of unemployment across the combined initial OPT and STEM extension periods. These are cumulative limits, not allowances that restart when a student changes jobs.
Periods without qualifying work can count as unemployment, including gaps between jobs. Students should track employment dates carefully, report changes as instructed, and contact the DSO promptly if a job ends or work details change. Exceeding the applicable limit can put F-1 status at risk.
Students are generally required to report employment and certain personal or employer information changes through the school or the SEVP Portal, according to the applicable rules and deadlines. The DSO can explain which reporting method applies. Keeping a dated record of employer details, work address, hours, job duties, and supervisor information can make reporting and later verification easier.
How the STEM OPT Extension Works
A student may be eligible for a 24-month STEM OPT extension after post-completion OPT if the degree is on the current DHS STEM Designated Degree Program List and the student meets other requirements. The degree must generally come from an appropriately accredited and SEVP-certified school. The student must also have qualifying employment with an employer enrolled in E-Verify.
STEM OPT has additional oversight requirements. The student and employer must complete and sign Form I-983, the Training Plan for STEM OPT Students, which describes learning objectives, supervision, and evaluation. The student must work at least 20 hours per week for each qualifying employer, and the position must be directly related to the STEM degree. The employer must provide genuine training and supervision rather than simply placing the student in a job without an appropriate plan.
Students generally apply for the extension during the 90 days before their current post-completion OPT EAD expires. The DSO must recommend the extension in SEVIS before the student files Form I-765. The application must reach USCIS before the current EAD expires. Students should confirm the exact requirements and deadlines with their DSO and review the ICE practical training guidance.
Travel, Status, and Common Risks
Travel outside the United States while an OPT application is pending or after approval can involve immigration risks. The documents needed for reentry may include a valid passport, valid F-1 visa (unless an exception applies), current Form I-20 with a recent travel signature, and an EAD. A student traveling while an application is pending should seek advice from the DSO before departure, because circumstances and reentry decisions vary.
An EAD does not guarantee admission to the United States, and it does not replace the F-1 visa or Form I-20. Students should also consider how a job gap, expired travel document, pending application, or change in school records could affect their situation. For case-specific travel or status questions, a qualified immigration attorney can provide advice that a general article cannot.
Common mistakes include starting work before the EAD start date, treating any job as related to the major, missing the DSO recommendation deadline, failing to report employment changes, and assuming a pending STEM extension application has been approved. Careful recordkeeping and early communication with the DSO can reduce these risks.
OPT, Taxes, and Employment Rights
OPT workers are generally subject to U.S. income tax rules. Federal, state, and local tax obligations depend on the individual’s circumstances, including tax residency and income. Some F-1 students who are nonresident aliens for tax purposes may be exempt from Social Security and Medicare taxes on authorized F-1 employment, but exceptions apply. Employers and students can consult IRS guidance or a tax professional for individual tax questions.
F-1 status does not remove workplace protections. Employers must follow applicable federal, state, and local labor laws, including rules on wages, workplace safety, and discrimination. An unpaid internship or volunteer arrangement must meet relevant legal standards; calling a position “unpaid” does not by itself make it lawful.
