Guide to the OPT for F-1 Students (2026)

TL;DR

• OPT is temporary work authorization for F-1 students that allows employment directly related to the major field of study. Standard post-completion OPT provides 12 months. STEM graduates may apply for a 24-month extension, for up to 36 months total.

• The application window for post-completion OPT is 90 days before to 60 days after the program end date. USCIS must receive the I-765 within 30 days of the DSO's SEVIS recommendation AND within this 90/60-day window. Missing either deadline results in denial and loss of the filing fee with no exceptions.

• Current I-765 processing times run approximately 3 to 5 months. Apply 90 days before graduation, not later. The EAD card lists the authorized start date; working even one day before that date is an immigration status violation.

• The unemployment limit is 90 cumulative days during standard 12-month OPT. During STEM OPT, the total unemployment limit across both periods combined is 150 days, not 150 additional days.

• All OPT employment must be directly related to the major field of study, at least 20 hours per week. Paid, unpaid, volunteer, and self-employment all count toward the 90-day unemployment clock if they meet those two conditions.

• STEM OPT requires an E-Verify enrolled employer, a completed Form I-983 Training Plan, and six-month self-evaluation reports. These are not optional compliance steps.

• A timely-filed STEM OPT I-765 automatically extends work authorization by 180 days while the application is pending.

• Using 12 or more months of full-time CPT at the same educational level eliminates OPT eligibility entirely at that level.

• As of December 12, 2025, USCIS no longer accepts self-submitted photos with the I-765. USCIS will schedule an Application Support Center biometrics appointment instead.

What OPT Is.

Optional Practical Training is a period of temporary employment authorization available to F-1 students. It allows work in positions directly related to the student's major field of study, either before graduation (pre-completion OPT) or after (post-completion OPT). OPT is not a separate visa. It is an employment benefit of F-1 status, authorized through Form I-765 and evidenced by an Employment Authorization Document (EAD).

OPT is available once per educational level completed in the United States. A student who uses 12-month OPT after a bachelor's degree and then earns a master's degree becomes eligible for a new 12-month OPT period at the master's level, plus STEM extension if applicable. There is no benefit in saving OPT from one level to combine with another; each level's OPT starts fresh, subject to the rules for that level.

Post-completion OPT is what most people mean when they say OPT. It begins after the student completes their degree requirements and is the foundation for the H-1B cap-gap extension and STEM OPT pathways. This guide focuses primarily on post-completion OPT and the STEM extension.

Post-Completion OPT

Eligibility

To be eligible for post-completion OPT, the F-1 student must:

• Have been enrolled full-time in a SEVP-certified school for at least one full academic year (two consecutive full semesters) in F-1 status.

• Be seeking or maintaining employment directly related to the major field of study listed on the I-20.

• Not have accumulated 12 or more months of full-time CPT at the same educational level. Full-time CPT from a previous school at the same degree level counts toward this total. CPT at a different degree level does not.

• Not have already used 12 months of post-completion OPT at the same degree level.

A job offer is not required to apply for OPT. Students may apply before securing employment. However, the 90-day unemployment clock begins running on the OPT start date regardless of whether a job has been found.

The Application Window and Filing Sequence

This is the most consequential timing element in the entire OPT process. The window is strict and has no exceptions.

The OPT application window opens 90 days before the program end date (the date on the I-20 by which the degree must be completed) and closes 60 days after the program end date. The I-765 must be received by USCIS within this window.

There is a second timing constraint: the I-765 must be filed within 30 days of the date the DSO enters the OPT recommendation into the student's SEVIS record and issues the updated I-20. If the I-765 is filed before the DSO recommendation or more than 30 days after it, USCIS will deny the application and the filing fee is not refunded.

The correct sequence:

• Step 1: The student requests an OPT recommendation from their Designated School Official (DSO) at the school's international student office. The student should initiate this at least 90 days before the program end date to allow for processing.

• Step 2: The DSO reviews eligibility, enters the OPT recommendation into the SEVIS record, and issues an updated Form I-20 reflecting the recommendation.

• Step 3: The student prepares and files Form I-765 with USCIS within 30 days of the I-20 issuance date and within the 90/60-day application window. The I-765 must include the DSO-endorsed I-20, the I-94 arrival record, a copy of the passport, and the filing fee.

• Step 4: USCIS adjudicates the application and mails the EAD card to the address on file.

• Step 5: The student may begin employment only on or after the start date printed on the EAD card, not before.

Processing Time and the Photo Change

Current USCIS processing times for the I-765 OPT application run approximately 3 to 5 months. This means that a student who applies 90 days before graduation will likely receive their EAD around or shortly after their program end date, depending on USCIS workload at the time.

Applying late, even by a few weeks, compresses this window significantly. A student who applies 50 days before graduation, rather than 90 days, may wait for their EAD well into the period when the 90-day unemployment clock is already running, losing weeks or months of usable work authorization to processing delay.

As of December 12, 2025, USCIS updated its photo policy. I-765 applicants no longer submit self-taken passport photos with the application. Instead, USCIS will send a notice scheduling a biometrics appointment at an Application Support Center (ASC) where fingerprints and a photo are collected. Students should factor this additional step into their planning and monitor for the ASC appointment notice after filing.

Choosing the OPT Start Date

The student selects an OPT start date when filing the I-765. The selected start date must fall within 60 days after the program end date. Two considerations govern this choice.

• Earlier start date: Work authorization begins sooner, but the 12-month clock starts immediately, leaving less time to find a job if the job search takes longer than anticipated. If the student is unable to find work for several weeks after the early start date, those weeks begin counting against the 90-day unemployment limit.

• Later start date: Provides more buffer time for the job search before the unemployment clock starts. For students without a confirmed job offer, selecting a date 30 to 45 days after graduation gives additional runway without risking unnecessary unemployment accrual.

The EAD will list whichever start date was selected. The student cannot work before that date even if the EAD card arrives early. The end date of the 12-month OPT is exactly 12 months from the start date listed on the EAD, not 12 months from the program end date.

Employment Rules During OPT

Field of Study Requirement

All OPT employment must be directly related to the major field of study on the I-20. The connection must be genuine and demonstrable. A computer science graduate writing code qualifies. A computer science graduate working as a sales assistant does not, regardless of whether the employer is in the technology sector.

USCIS and SEVP do not provide a comprehensive list of what qualifies for each degree field. The student and their DSO must evaluate each position. When in doubt, ask the DSO before accepting a position.

Employment Types That Count

Paid employment in a directly related position is the most common form of OPT employment.

Unpaid internships and volunteer positions count as employment for OPT purposes, provided the work is directly related to the field of study, the arrangement does not violate any labor laws, and the student is working at least 20 hours per week. If the unpaid work is fewer than 20 hours per week, those days count as unemployment toward the 90-day limit.

Multiple employers are permitted simultaneously. A student may hold two or three part-time positions at the same time, as long as each is related to the field of study and the combined hours reach at least 20 per week.

Self-employment is permitted during standard 12-month OPT. The student must be the employer of record, the work must be in the field of study, and the arrangement must constitute genuine employment activity rather than a paper structure. Self-employment is not available during STEM OPT, which requires a formal employer-employee relationship with a specific E-Verify enrolled employer.

The 90-Day Unemployment Limit

During standard post-completion OPT, a student may not accumulate more than 90 cumulative days of unemployment. The clock begins on the OPT start date printed on the EAD, not on graduation day or the program end date.

Days count as unemployment when the student is not engaged in at least 20 hours per week of employment directly related to their field of study. Approved vacation time from an employer, paid holidays, and medical leave from an active employer generally do not count as unemployment if the employment relationship is ongoing and documented. 

Days between positions, periods of unrelated work, and weeks with fewer than 20 hours of qualifying employment all count.

At 90 cumulative days, the student is in violation of F-1 status. The consequence is termination of the SEVIS record, which ends F-1 status immediately. There is no grace period after the 90th day of unemployment. The student is expected to depart the United States, transfer to a new school, or change to another nonimmigrant status before reaching that limit.

Tracking unemployment days is the student's responsibility. The DSO can see unemployment accrual in SEVIS but is not required to proactively alert every student approaching the limit. Students should maintain their own log.

Reporting Requirements

Every employment change must be reported to the DSO through the school's portal (often the SEVP Portal) within 10 days of the change. This includes starting a new job, ending a job, changing employers, changing a work address, or changing the nature of employment. 

Unreported employment changes do not pause the unemployment clock; the system will treat unreported periods as unemployment accrual.

The STEM OPT Extension

Overview

F-1 students who have completed a bachelor's, master's, or doctoral degree in a field on the DHS STEM Designated Degree Program List may apply for a 24-month extension of their post-completion OPT. The STEM extension must be applied for before the initial 12-month OPT EAD expires. It may not be applied for during the 60-day grace period that follows OPT expiration.

The STEM extension adds 24 months of work authorization, for a total of 36 months of combined OPT. Within that 36-month window, STEM-eligible students can enter the H-1B cap lottery up to three times.

STEM OPT Application Window

The I-765 for the STEM extension may be filed up to 90 days before the current OPT EAD expires and must be received by USCIS no later than the EAD expiration date. There is also the 60-day post-DSO-recommendation window that applies as with standard OPT. The I-765 must be filed within 60 days of the DSO recommending the STEM extension in SEVIS.

USCIS must receive the I-765 before the current EAD expires. Do not wait until the last day. DSO processing times vary, international offices at large universities often have multi-week queues, and the student cannot file until the DSO has issued the updated I-20 with the STEM recommendation.

If the STEM OPT I-765 is timely filed (received by USCIS before the OPT EAD expires), work authorization is automatically extended for up to 180 days while USCIS adjudicates the application. 

The USCIS receipt notice serves as evidence of this extended work authorization for I-9 purposes. If USCIS denies the extension, work authorization ends immediately and the student enters the 60-day grace period.

Employer Requirements for STEM OPT

The employer must be enrolled in and maintaining good standing with the USCIS E-Verify employment eligibility verification program. An employer that is not E-Verify enrolled cannot sponsor STEM OPT. The student must verify E-Verify enrollment with the employer before filing.

The employer must provide the student with formal training that is related to the qualifying STEM degree and must document this through Form I-983, Training Plan for STEM OPT Students. The I-983 is completed jointly by the student and the employer and submitted to the DSO before the DSO can recommend the STEM extension. The I-983 must describe specific learning objectives, training activities, and how the training relates to the STEM degree.

A bona fide employer-employee relationship must exist. Staffing arrangements where the student formally works for one entity but performs work supervised by a different entity can raise compliance issues. The employer that signs the Form I-983 must be the entity that directly provides and supervises the training experience.

Self-employment is not permitted during STEM OPT.

Reporting Requirements During STEM OPT

STEM OPT carries substantially more compliance reporting than standard OPT.

Every six months, the student must complete a self-evaluation of their training progress and submit it to the DSO. At the 12-month mark, the student submits a formal training progress report. At the 24-month mark, the student submits a final assessment. These are filed through the DSO and must be co-signed by the employer.

The employer must report to the DSO within five business days whenever the student leaves employment, whether through resignation, termination, or other separation.

The student must report address changes and employment changes to the DSO within 10 days.

SEVP may conduct site visits to verify that the training plan is being implemented as described. USCIS may issue Requests for Evidence or initiate compliance reviews.

The STEM OPT Unemployment Limit

The 150-day cumulative unemployment limit across both OPT periods is a specific, bounded total, not an addition of 60 new days on top of a fresh 90-day clock.

The math works as follows: during standard OPT, the maximum allowed unemployment is 90 days. During the combined OPT period (standard plus STEM), the maximum allowed is 150 days total. The 60 additional days are not a fresh allocation for the STEM period alone.

If a student accrues 30 days of unemployment during standard OPT, they have 120 days remaining for the STEM period (150 minus 30). If a student uses all 90 days of unemployment during standard OPT, they have only 60 days remaining for the 24-month STEM period. A student who hits 90 days during standard OPT becomes ineligible for the STEM extension at all, because exceeding the 90-day limit during standard OPT is itself a status violation.

The CPT Warning & Differences

Curricular Practical Training is a separate employment authorization for F-1 students during their degree program, tied to specific course curriculum. CPT and OPT interact in one critical way: a student who accumulates 12 or more months of full-time CPT (20 or more hours per week) at the same educational level loses eligibility for post-completion OPT at that level entirely.

Full-time CPT from a prior institution at the same degree level counts toward this total. Part-time CPT (fewer than 20 hours per week) does not affect OPT eligibility.

This rule matters most for students who use CPT heavily during master's programs to fund tuition or for students who switch schools and carry CPT time from a prior institution. Before accepting any CPT position, the student should calculate their running total and evaluate whether it will cross the 12-month threshold.

The rule also has implications for Day 1 CPT programs, which advertise CPT authorization from the first day of enrollment before any coursework has been completed. SEVP has been actively scrutinizing programs that offer Day 1 CPT, and several have lost SEVP certification. 

A student enrolled in a program that loses SEVP certification loses their immigration status simultaneously. Anyone considering a program primarily for Day 1 CPT should consult with an immigration attorney and independently verify the program's SEVP certification status and accreditation standing before enrolling.

Travel Restrictions & Preparations During OPT

Standard Post-Completion OPT

Travel outside the United States during OPT is permitted but requires careful preparation. To re-enter in F-1 status while on OPT, the student must have:

A valid, unexpired F-1 visa stamp in their passport. The F-1 visa stamp must not be expired. If it is, the student must obtain a new F-1 stamp at a U.S. consulate abroad before returning, which requires an interview and may involve extended wait times at some posts.

A valid EAD card showing an active OPT period.

An I-20 with a travel signature from the DSO dated within the last six months. The travel signature is the endorsement on page 2 of the I-20 confirming the student is in good standing and the international office approves the travel.

Evidence of employment, such as an offer letter, recent pay stubs, or an employer letter confirming the ongoing position. CBP officers at ports of entry may ask why the student is returning and what employment they hold.

Traveling before the EAD is approved is high risk. If a student departs the United States before receiving the EAD and re-enters after their program end date but before the OPT is approved, they may have difficulty demonstrating they are in authorized status for the purposes of re-entry.

Traveling without a job is riskier than traveling while employed. A student between positions who departs the United States is not guaranteed re-entry. CBP has discretion to admit or deny based on whether the officer believes the student maintains a nonimmigrant intent and has reason to return to the United States. An offer letter and signed employment agreement substantially reduce this risk.

Days spent outside the United States during OPT do not pause the 90-day unemployment clock if the student does not have a qualifying position during those days.

STEM OPT Travel

Travel rules during STEM OPT are similar to standard OPT: valid F-1 visa, valid STEM OPT EAD, updated I-20 with travel signature, and evidence of employment. Students on STEM OPT should additionally carry a copy of the approved STEM OPT EAD and, if the previous EAD was recently renewed, both the prior and current EAD.

The OPT to H-1B Bridge

How the Transition Works

The H-1B cap-subject lottery runs each March. If an employer registers the student and the registration is selected, the employer files Form I-129 with a requested start date of October 1. The H-1B starts October 1.

If the student's OPT EAD expires between June and September 30, there is a gap between OPT ending and H-1B beginning. The cap-gap provision automatically extends F-1 status and OPT work authorization for students whose H-1B petition was timely filed with a request for change of status through October 1.

The cap-gap extension applies only if the H-1B registration was selected, the petition was filed with a change of status request (not consular processing), and the petition was received by USCIS before the OPT expired or during the 60-day grace period following OPT.

If the H-1B petition is denied or withdrawn, the cap-gap extension terminates immediately and the student enters the 60-day grace period. If the H-1B petition is pending on October 1 (rare but possible in complicated cases), work authorization ends until the petition is approved.

If Not Selected in the Lottery

Students not selected in the H-1B lottery should evaluate:

• STEM OPT extension, if not yet filed. This provides up to 24 more months and allows participation in the next two lottery cycles.

• Cap-exempt H-1B employment at universities, nonprofit research organizations, or affiliated institutions. These employers can file H-1B petitions at any time without lottery participation.

• O-1A for those with qualifying records of extraordinary ability.

• TN for Canadian or Mexican nationals in qualifying USMCA occupations.

A lottery non-selection does not affect F-1 or OPT status. The 90-day unemployment clock continues running during any period without qualifying employment, including after a lottery result.

Key Rules and Common Mistakes

Rules That Cannot Be Overlooked

• The 30-day I-765 filing window after DSO recommendation: many students receive the updated I-20 and then wait several weeks to file, not realizing there is a hard 30-day limit from the I-20 issuance date.

• Employment before the EAD start date: the start date on the EAD card is when work authorization begins, not when the card arrives in the mail. A card that arrives 10 days early does not authorize starting 10 days early.

• Field of study requirement applies to all employment: every position held during OPT must be demonstrably related to the degree. An unrelated side job, even one hour per week, creates a compliance issue.

• Reporting within 10 days: failure to report employer changes within 10 days means days without a current employer in SEVIS are counted as unemployment regardless of actual work activity.

Part-time work below 20 hours per week in a related position counts as unemployment for the 90-day limit, even if the student is working and earning money.

Frequently Asked Questions

Do I need a job offer to apply for OPT?

No. A job offer is not required to apply for post-completion OPT. However, the 90-day unemployment clock begins on the OPT start date regardless of whether employment has been secured. Students who apply without a job offer should select a later start date to maximize the time available before the unemployment clock becomes a concern.

Can I work for multiple employers on OPT?

Yes. Multiple simultaneous positions are allowed, as long as each is directly related to the field of study and the combined hours total at least 20 per week. Each employer must be reported to the DSO within 10 days of starting.

Can I do my own freelance or consulting work on OPT?

Yes, during the standard 12-month OPT. Self-employment is permitted if the student is the employer of record and the work is related to the field of study. Self-employment is not available during STEM OPT, which requires a formal employer-employee relationship with a specific E-Verify enrolled company.

Does my OPT time reset if I earn a new degree?

OPT is available once per educational level. A student who completed OPT after a bachelor's degree and then earns a master's degree is eligible for a new 12-month OPT period (and STEM extension if applicable) at the master's level.

What happens if USCIS has not adjudicated my STEM OPT application when my current OPT EAD expires?

If the STEM OPT I-765 was received by USCIS before the OPT EAD expired, work authorization is automatically extended for up to 180 days from the EAD expiration date while the application is pending.

The USCIS receipt notice (Form I-797) serves as the evidence of this extended authorization. If the application is still pending after 180 days, work authorization ends until USCIS issues a decision.
