OPT in the USA Explained 2026: Eligibility, STEM Extension and How to Apply

Optional Practical Training, known to every F-1 student simply as OPT, is the main way international graduates work in the United States after finishing a degree. It is temporary employment authorisation from US Citizenship and Immigration Services (USCIS) for work that is directly related to your major area of study. It is also a system of unforgiving deadlines. File too early and USCIS can reject the application. File too late and you lose the benefit entirely, with no appeal based on having misunderstood the window. Work one day before your authorisation starts, exceed your unemployment limit by one day, or fail to report a job on time, and you can fall out of F-1 status while holding an approval notice that looks perfectly valid. OPT rewards students who understand its rules early and punishes, quietly and automatically through the SEVIS record, those who learn them late.

This guide explains OPT as USCIS and the Department of Homeland Security’s Study in the States program define it: who is eligible, the difference between pre-completion and post-completion OPT, the exact filing windows for the standard twelve months and for the twenty-four-month STEM extension, how unemployment days are counted, what the STEM extension demands from you and your employer through E-Verify and Form I-983, and the reporting duties that continue for the whole of your training period. It is written for F-1 students approaching graduation in 2026 and for students choosing a US degree now who want to understand, before they commit their money, what the post-study work system will and will not do for them. Every rule stated here comes from the official USCIS pages on Optional Practical Training and the STEM OPT extension, or from the Study in the States STEM OPT Hub, both checked at the time of writing and listed in the Sources and Verification section. Where a fee or processing practice can change, this guide tells you to check the current USCIS page rather than quoting a figure that may be superseded by the time you file.

Two habits will protect you throughout. First, treat your Designated School Official (DSO) as part of the application, not as an adviser you consult afterwards, because no OPT application can be filed correctly without a DSO recommendation entered in SEVIS and printed on your Form I-20. Second, use planning tools to stay ahead of the calendar: the application deadline finder helps you map your program end date against the filing windows in this guide, and the document checklist helps you assemble the I-20, passport, I-94 record and photographs that a complete filing requires.

OPT at a Glance

Read the table with one warning in mind: the twelve months of OPT are a single bank of time at each degree level. Pre-completion OPT used during your studies is deducted from that bank, part-time pre-completion OPT at half the rate and full-time pre-completion OPT day for day, so most students who are free to choose preserve the full twelve months for after graduation. You cannot receive OPT twice at the same degree level, and completing a second degree at the same level, such as a second master’s, does not create a second twelve months. A genuinely higher degree level, a bachelor’s followed by a master’s, or a master’s followed by a doctorate, creates a new period of eligibility.

Who Is Eligible for OPT?

USCIS eligibility for OPT rests on a small number of conditions, all of which must be true at the same time. You must be in valid F-1 status. You must have been lawfully enrolled on a full-time basis for at least one full academic year at a school certified by the Student and Exchange Visitor Program (SEVP). The training must be directly related to your major area of study, a test that is applied job by job, not degree by degree in the abstract: a data role for a computer science graduate is straightforward, while the same graduate taking an unrelated sales role would not satisfy the requirement, and you should be able to explain the relationship in a sentence or two for every job you report. You must not have already used twelve months of OPT at the same degree level or a higher level. And you must not have been authorised for twelve months or more of full-time Curricular Practical Training (CPT) at the same degree level, because reaching that CPT threshold removes OPT eligibility at that level entirely. Part-time CPT does not have that effect, which is why students and DSOs track full-time CPT months so carefully during a degree.

You do not need a job offer to apply for post-completion OPT. This surprises many students, who assume the application works like a work visa sponsored by an employer. It does not. Post-completion OPT is your authorisation, granted on the basis of your degree, and you search for work inside the authorised period while your unemployment clock runs. That design cuts both ways. It lets you apply on a predictable academic calendar without an employer in hand, and it means the ninety-day unemployment limit begins whether or not the job market cooperates, which is why the choice of start date and the intensity of your final-year job search matter as much as the application itself.

Students sometimes ask whether OPT is available after every kind of program. The authorisation attaches to study at an SEVP-certified school in F-1 status, and the one-academic-year enrolment requirement excludes short programs that do not reach a full academic year of full-time enrolment. English language students in F-1 status do not qualify for OPT on the basis of language study. If you are comparing US programs partly for their OPT value, confirm with the school’s international office, before you enrol, that the program is SEVP-certified for F-1 students and long enough to establish eligibility, and compare institutions through the university directory as a starting point for that conversation.

Pre-Completion vs Post-Completion OPT

Pre-completion OPT is training taken before you finish your program, once you have completed the required full academic year of enrolment. While school is in session it is limited to part-time work of no more than twenty hours per week; during official holidays it can be full time. You must keep studying full time alongside it, and every period of pre-completion OPT is deducted from your twelve-month total, with part-time periods counted at half the rate. Because Curricular Practical Training usually serves curriculum-required internships more simply, most students use little or no pre-completion OPT, reserving their authorisation for after graduation. Where pre-completion OPT does make sense is for a valuable off-campus opportunity that is not CPT-eligible, chosen with your DSO’s advice and with the deduction to your post-completion time priced in openly.

Post-completion OPT is the form almost every graduate uses: up to twelve months of full-time authorisation beginning after your program end date. You choose a requested start date that falls within the sixty days following your program end date. Choosing the earliest date gets you working soonest but starts your unemployment clock immediately; choosing a later date preserves time if you have no job lined up, at the cost of delaying when you can begin. You may not begin working, even for training or an unpaid start, until USCIS has approved the application, you have received your Employment Authorization Document, the card commonly called the EAD, and the start date printed on it has arrived. Working before that point is unauthorised employment, and no employer’s urgency changes the rule.

How to Apply for Post-Completion OPT, Step by Step

Step one is a conversation with your DSO, ideally early in your final term. You confirm your program end date, because that date, as recorded in SEVIS, anchors every deadline that follows, and you confirm you have not compromised eligibility through full-time CPT or a prior OPT at the same level. Step two is the DSO recommendation: the DSO enters the OPT recommendation in SEVIS and issues you a new Form I-20 showing it. Step three is filing Form I-765, Application for Employment Authorization, with USCIS, under the post-completion OPT category (c)(3)(B), either online through a USCIS account or by mail following the current form instructions. Your filing must include the OPT I-20, copies of your passport and prior immigration documents as the instructions require, photographs meeting the specification, and the correct current filing fee. USCIS filing fees for Form I-765 change over time and differ between online and paper filing, so take the amount from the USCIS Form I-765 page or the USCIS fee schedule on the day you file, never from an older guide, including this one.

The filing window has three edges, and all three must be satisfied. USCIS must receive your application no earlier than ninety days before your program end date. USCIS must receive it no later than sixty days after your program end date. And USCIS must receive it within thirty days of the date your DSO entered the OPT recommendation in SEVIS. The thirty-day rule is the one that catches students who collect their I-20 and then delay: an I-20 recommendation can go stale while the ninety-to-sixty-day window is still open, and a filing made on day thirty-one after the recommendation is late even if your program ended only last week. If your recommendation does age out, return to your DSO for a new one before filing, provided you are still inside the outer window. Step four is waiting: USCIS processes the application and, if it is approved, produces your EAD and mails it to the address on your application, so that address must be one where you can reliably receive government mail for months ahead, or you must follow USCIS instructions on mailing addresses precisely. Premium processing is available for OPT applications through Form I-907 for an additional fee; check the USCIS premium processing page for the current fee and the processing clock before deciding whether it is worth paying in your case.

Step five is starting correctly. When the EAD arrives, check every detail on it, your name, dates and category, and report errors to USCIS promptly. Give your employer the documents it needs for Form I-9 employment eligibility verification. Then report your employment to your DSO or through the SEVP Portal as soon as you start, and within ten days of any later change. Your sixty-day grace period after your program end date, during which many students are waiting for the EAD, is not work authorisation: presence is permitted while a timely application is pending inside its rules, but employment is not, until the EAD start date arrives.

Unemployment Days: The Clock That Ends OPT

During post-completion OPT you may be unemployed for a maximum of ninety days in total. The count is cumulative across the whole OPT period, not a fresh allowance per job, and it begins on the start date printed on your EAD, not on your graduation day and not on the day you start looking for work. Days spent outside the United States while unemployed still count, and days between jobs count in full. If you reach the limit, you are no longer maintaining the terms of your OPT, and you should speak to your DSO immediately about your options, which can include departing the United States within your grace period, transferring to a new program of study, or changing to another status if you are eligible, because simply continuing to look for work beyond the limit is not one of the options.

The practical defence against the clock is early, documented job searching combined with the breadth of what counts as employment on standard OPT. On the initial twelve months, employment can include multiple concurrent employers, work for hire, and, under Study in the States guidance, volunteer or unpaid work in your field of at least twenty hours per week, which can stop the unemployment count while you gain experience; every arrangement must be genuinely related to your major and must be reported. Keep evidence for everything: offer letters, contracts, payslips, volunteer agreements describing your duties and hours, and a log of start and end dates. If USCIS, your DSO, or a future visa officer asks you to demonstrate that you were employed and in status during OPT, this file is your answer. Students who cannot reconstruct their OPT employment history face problems in later applications that have nothing to do with the quality of their work.

The 24-Month STEM OPT Extension

If your qualifying degree is in a STEM field on the Department of Homeland Security’s STEM Designated Degree Program List, you may apply for a twenty-four-month extension of your post-completion OPT, giving thirty-six months of authorisation in total. USCIS sets the conditions, and they are stricter than for standard OPT in every dimension. You must currently be in a valid period of post-completion OPT. Your STEM degree must be a bachelor’s, master’s or doctoral degree from a school that is accredited by a US Department of Education-recognised accrediting agency and SEVP-certified at the time you submit the extension application, and the degree program must appear on the current DHS STEM list; check your exact program’s Classification of Instructional Programs code against that list with your DSO, because a degree that sounds like science or technology is not automatically a designated STEM program. The job must be directly related to that STEM degree, paid, and for at least twenty hours per week. Unpaid and volunteer work, which can count on standard OPT, does not count as employment on the STEM extension.

Two routes to the qualifying degree catch students out pleasantly and unpleasantly. Pleasantly, USCIS confirms you may base a STEM extension on a previously earned STEM degree, even if your current post-completion OPT rests on a later non-STEM degree, provided both degrees are from accredited, SEVP-certified institutions, you have not already had a STEM extension based on that earlier degree, and the training opportunity is directly related to the earlier STEM degree. Unpleasantly, the lifetime structure is capped: a further STEM extension is possible after a new qualifying STEM degree at a higher educational level, as USCIS illustrates with a bachelor’s-level extension followed later by a master’s-level extension, but you cannot repeat extensions at the same level. Plan degree choices with that architecture in mind rather than discovering it at graduation.

The Employer Requirements: E-Verify, EIN and the Bona Fide Relationship

On STEM OPT, your employer is regulated almost as much as you are. The employer must be enrolled in E-Verify and remain a participant in good standing, must have an Employer Identification Number (EIN) issued by the Internal Revenue Service, and your Form I-765 must state the employer’s name exactly as listed in E-Verify together with its E-Verify company identification number, or a valid E-Verify client company identification number where an employer agent is used. Confirm the employer’s E-Verify enrolment and number before you accept the offer as your STEM employer, and in writing, because an employer that is not enrolled when you file cannot support the extension, and an employer that leaves E-Verify puts your authorisation at risk. The employer must maintain a bona fide employer-employee relationship with you: the employer that signs your training plan must be the same entity that actually provides your training, it must have sufficient resources and trained supervisory personnel to deliver that training at the locations listed in the plan, you must not replace a US worker, and your duties, hours and compensation must be commensurate with those of similarly situated US workers. Self-employment cannot satisfy the extension, because you cannot supervise your own training. Staffing and consulting arrangements are examined closely, and only work where the signing employer genuinely directs and trains you can qualify. The Department of Homeland Security may conduct a site visit, with or without the notice arrangements described in the regulation, to verify that the training described in your plan is the training actually happening.

Form I-983: The Training Plan at the Centre of STEM OPT

Before your DSO can recommend the extension, you and your employer must complete Form I-983, Training Plan for STEM OPT Students, together. The form records your training goals, how the opportunity relates directly to your STEM degree, the employer’s training resources and supervision, and how your progress will be measured. It is submitted to your DSO, not to USCIS, but it is not a formality: USCIS and DHS can request it, your employer attests to its contents by signing it, and your actual job must match it for the whole extension. You must submit a self-evaluation of your training progress, signed by your employer, at the twelve-month point and a final evaluation at the end of the training period, with a final evaluation also due when employment with that employer ends earlier. Any material change, to your job duties, employer, worksite, hours, compensation or supervisor, requires an updated Form I-983 submitted to your DSO at the earliest opportunity, and your employer must report your termination or departure to your DSO within five business days. Think of the I-983 as a living compliance document you maintain for two years, not a form you file once and forget.

How and When to File the STEM Extension

The sequence mirrors standard OPT with tighter edges. First, complete Form I-983 with your prospective STEM employer. Second, give it to your DSO, who reviews it and issues a new Form I-20 with the STEM OPT recommendation, endorsed within the sixty days before you file. Third, file Form I-765 under the STEM category (c)(3)(C) with the correct current fee, your employer’s E-Verify details as above, the endorsed I-20, and a copy of your STEM degree. You may file up to ninety days before your current OPT authorisation expires, and USCIS must receive the application no later than that expiry date, and within sixty days of the date your DSO entered the recommendation in SEVIS. There is no sixty-days-after window for the STEM extension as there is for initial post-completion OPT: a STEM filing that arrives after your EAD has expired is too late, full stop. The protection for timely filers is the automatic extension: if you properly filed before expiry and your OPT period ends while the application is pending, USCIS automatically extends your employment authorisation for up to one hundred and eighty days while it decides, and your employer can reverify your Form I-9 using your existing EAD together with the endorsed I-20 and your filing receipt as the USCIS instructions describe.

Costs and Fees Table

Reporting Duties and Staying in Status on OPT

OPT is a reporting regime from start to finish. On standard post-completion OPT you must report your employment, any change of employer, and any change of address within ten days, through your DSO or the SEVP Portal, and you remain in F-1 status throughout, which means your SEVIS record, your I-20 and your actual activity must agree at all times. On STEM OPT the duties intensify: report changes to your legal name, residential or mailing address, email address, employer name and employer address to your DSO within ten days of the change; report to your DSO every six months to confirm your information even if nothing has changed; submit the twelve-month and final I-983 evaluations on schedule; and ensure material changes are captured in an updated I-983. Missing a six-month validation is not a minor lapse; SEVIS records can be terminated for failure to report, and a terminated record ends your status and your authorisation together. Set calendar reminders for every six-month validation on the day your STEM EAD starts, not when the first reminder email arrives.

Travel during OPT requires care rather than avoidance. Study in the States advises students on OPT who travel internationally to carry their passport, a valid F-1 visa, their I-20 endorsed for travel within the validity period your DSO specifies, their EAD, and evidence of employment such as an employer letter. Travel after your program ends but before OPT is approved, or while you are unemployed and accumulating days, carries additional risk, and the unemployment clock keeps running while you are abroad. Discuss any international trip with your DSO before booking, particularly during the STEM extension, and never let a trip delay a filing deadline, because the STEM deadline in particular cannot be rescued from overseas.

When OPT ends, you have a sixty-day grace period after your authorised end date to prepare to depart the United States, transfer to another SEVP-certified school, or change status if you are eligible and have filed appropriately. Students who are the beneficiaries of a timely filed H-1B petition requesting a change of status may qualify for cap-gap relief that extends F-1 status and, where the conditions are met, OPT work authorisation until the H-1B takes effect; cap-gap is automatic in SEVIS when its conditions are satisfied, but it depends on your employer filing correctly and on time, and you should confirm your cap-gap I-20 with your DSO. Nothing in the OPT system extends itself because your job is going well or your employer is willing: every continuation, the STEM extension, cap-gap, a new degree, a change of status, requires its own timely, correct filing. Students weighing that uncertainty against other countries’ post-study systems can compare the structure directly in the Germany vs USA comparison and plan a longer-term career map with the career path explorer.

Common Mistakes

The costliest mistake is missing a filing window: filing post-completion OPT more than thirty days after the DSO recommendation, filing the STEM extension after the EAD expiry date, or assuming the sixty-days-after window for initial OPT also exists for STEM. It does not. The second mistake is working too early, starting a role, a training week, or even unpaid onboarding before the EAD start date, or continuing to work after authorisation ends while an extension that was filed late is pending. The third is losing count of unemployment days, especially by choosing the earliest possible start date with no job arranged and then searching slowly; ninety days passes faster than graduates expect. The fourth is a STEM-specific cluster: accepting a job with an employer that is not in E-Verify, treating Form I-983 as paperwork that need not match the real job, missing the twelve-month evaluation, or forgetting a six-month validation because nothing changed, when the rule requires validation precisely even when nothing changed. The fifth is burning OPT accidentally, by accumulating twelve months of full-time CPT at the same degree level during the degree and discovering at graduation that OPT eligibility is gone. The sixth is relying on an old filing fee, an old form edition, or a mailing address you are about to leave; USCIS rejects filings for incorrect fees and superseded forms, and a rejection notice that reaches an old address can consume the very window you need to refile.

Practical Tips

Work backwards from your program end date and put every date in this guide on one page: the ninety-day opening of your filing window, the day you will request your DSO recommendation, your chosen requested start date, and the sixtieth day after your program ends as the absolute last filing day. Request the recommendation only when you are ready to file within thirty days of it. Start your job search in your final year, not your final month, aiming to begin employment as close to your EAD start date as the market allows, and keep a written unemployment-day tally from day one. Photograph or scan every document you file and every notice you receive, and keep the EAD itself safe, since replacing it requires a new application and fee. For STEM students, interview your employer as carefully as it interviews you: ask for its exact E-Verify company name and identification number, ask who will supervise your training and sign your evaluations, and walk away from any arrangement where the employer signing the I-983 will not be the employer directing your work. Students still preparing for the earlier stages of the US journey, including the visa interview that precedes any of this, can prepare with the F-1 visa interview guide.

Frequently Asked Questions

Do I need a job offer before I apply for OPT?

No. For post-completion OPT you apply on the basis of your completed degree and your DSO’s recommendation, without an employer. You search for work during the authorised period. The trade-off is that your ninety-day unemployment limit starts on your EAD start date whether or not you have found a job, so apply with a job search already under way.

When exactly can I file for post-completion OPT?

USCIS must receive your Form I-765 no earlier than ninety days before your program end date and no later than sixty days after it, and within thirty days of the date your DSO entered the OPT recommendation in SEVIS. All three conditions must be met. You also choose a requested start date within the sixty days after your program end date.

How many days can I be unemployed on OPT?

Ninety days in total during post-completion OPT. If you receive the twenty-four-month STEM extension, you receive sixty additional days, for a combined maximum of one hundred and fifty days across both periods. The count is cumulative, starts on your EAD start date, and includes days between jobs and days abroad while unemployed.

What makes a degree count as STEM for the extension?

The degree must be a bachelor’s, master’s or doctoral degree in a field on the Department of Homeland Security’s STEM Designated Degree Program List, earned from an accredited, SEVP-certified school. Your DSO can confirm whether your program’s classification code appears on the current list. A degree that sounds technical is not enough if its program is not on the list.

What are E-Verify and Form I-983, and why do they matter?

E-Verify is the federal system employers use to confirm employment eligibility; your STEM OPT employer must be enrolled in it, in good standing, and its E-Verify name and company identification number go on your Form I-765. Form I-983 is the training plan you and your employer complete and sign before your DSO recommends the extension. It defines your training goals, supervision and evaluation, is kept by your DSO rather than sent to USCIS, and your real job must match it, with evaluations due at twelve months and at the end of training.

Can I be self-employed or volunteer on OPT?

On standard post-completion OPT, volunteer or unpaid work in your field of at least twenty hours per week can count as employment for maintaining status, and multiple employers are permitted, provided everything is directly related to your major and reported. On the STEM extension the rules are stricter: employment must be paid, at least twenty hours per week, for an E-Verify employer with a bona fide employer-employee relationship, and self-employment does not qualify because you cannot supervise your own training.

What happens if my OPT expires while my STEM extension is pending?

If you filed the STEM extension properly and on time, before your OPT authorisation expired, USCIS automatically extends your employment authorisation for up to one hundred and eighty days while the application is pending. This protection depends entirely on timely filing; an application received after your EAD expiry date receives no automatic extension and is too late.

Can my spouse work while I am on OPT?

No. A spouse in F-2 status, which is the dependant status that accompanies F-1 students including during OPT, is not permitted to work in the United States. Households budgeting for a period of study followed by OPT should plan on that basis and not assume any dependant work income.
