For many international students, graduation day brings two feelings at once: pride in finishing, and a quiet worry about what happens next. The student visa that made everything possible is tied to being a student, so what are you supposed to do when the degree is done? For a large number of graduates, the answer is a program called Optional Practical Training, usually shortened to OPT.
OPT lets F-1 students work in the United States in a job related to their field of study, either during their program or after completing it. For students in certain science, technology, engineering and math fields, there’s an extension that can add up to two more years. It’s one of the most valuable features of the U.S. student visa system, and also one of the easiest to mishandle, because the rules are strict and the deadlines are unforgiving. This guide explains how OPT works, how to apply, how the STEM extension works and the mistakes that put students’ status at risk.
What OPT Is
Optional Practical Training is temporary employment authorization directly related to your major. It’s part of your F-1 status, which means you’re still a student in the eyes of immigration law while you’re on OPT. You can work for an employer, work for multiple employers, work as a contractor in some situations or start your own business, as long as the work is related to your degree and meets the program’s requirements.
OPT isn’t a separate visa. It doesn’t replace the F-1 status. It’s a benefit that you apply for, and approval is shown on a work permit card called an Employment Authorization Document.
Pre-Completion and Post-Completion OPT
There are two timing options. Pre-completion OPT is used while you’re still studying, usually part-time during the academic year or full-time during breaks. Post-completion OPT starts after you finish your degree requirements. Most students use post-completion OPT because it allows full-time work in their field.
The key rule is that you get a total of twelve months of OPT per education level. If you use part of it before graduation, the time is deducted from your post-completion allowance, with part-time pre-completion OPT counting at half the rate. Because every day counts, think carefully before using pre-completion OPT, especially if you want the maximum time after graduation. You can receive a new twelve-month period when you move up to a higher degree level, such as from a bachelor’s to a master’s degree.
Who Is Eligible
To qualify for OPT, you must be in valid F-1 status and have been enrolled full-time for at least one full academic year at a school authorized to recommend OPT. Your work must be directly related to your major field of study, and the authorization is tied to the degree level for which you’re applying. Certain circumstances, such as having completed a language training program rather than a degree, may limit eligibility.
The Application Process Step by Step
Step 1: Talk to your school’s international office
Your Designated School Official, or DSO, is a key partner in the process. They’ll explain your school’s procedures, deadlines and any forms. Start this conversation several months before your program ends.
Step 2: Get the recommendation in SEVIS
The DSO reviews your request and enters an OPT recommendation in the SEVIS system, then issues an updated Form I-20 showing the recommendation. You’ll sign it and keep it for your application.
Step 3: File Form I-765
You apply to USCIS for an Employment Authorization Document using Form I-765, along with the filing fee, the I-20 with the OPT recommendation, a copy of your passport, visa, I-94 record, passport-style photos if required and any other supporting documents specified in the instructions. Many applicants can file online.
Step 4: Wait for approval and your card
USCIS will send a receipt notice, and later your approval and the card. You can’t start working until you have the card in hand and the start date shown on it has arrived. Working before that date is a violation that can jeopardize your status.
Timing: The Rules That Catch People Out
The filing window is one of the most important details in the entire process. For post-completion OPT, you can generally file up to ninety days before your program end date and no later than sixty days after it. Applications filed outside this window are rejected or denied, and you can’t simply apply again later.
Processing times vary and can take several months. Students often file as early as allowed, because the start date of your OPT is generally set based on the dates you request and the dates of approval, and waiting for a card without being able to work can be financially stressful. Plan ahead for the possibility of a gap between graduation and the start of work, and don’t make plans that depend on starting on a specific day.
Finding a Job During OPT
You don’t need a job offer to apply for OPT, but you do need to find work within a limited time once your card is valid. While on post-completion OPT, you’re allowed no more than ninety days of unemployment in total. Days are counted from the start date of your OPT period, and they accumulate whenever you’re not working. Exceeding the limit can lead to termination of your status.
Start your job search early, using your school’s career center, alumni networks, internship connections and professional contacts. Employers are increasingly familiar with OPT, but some are not, so be prepared to explain it simply: you’re authorized to work for twelve months, or up to thirty-six months for eligible STEM degrees, without the employer needing to file anything on your behalf at that stage.
What Counts as Qualifying Work
Your work must be directly related to your degree, which means the job’s duties should connect to the knowledge you gained in your major. A computer science graduate working as a software developer is clearly related. The same graduate working as a restaurant server isn’t. Part-time work is allowed, though it must meet minimum weekly hour thresholds for the period to count as employment: generally at least twenty hours per week for OPT and a higher standard for STEM OPT. Self-employment and some forms of contract work can qualify if you can document the relationship to your degree and your active work, but be careful and ask your DSO before relying on them.
Reporting Requirements
During OPT you must keep your school informed. You generally need to report changes such as your address, employer information and employment status to your DSO within ten days, usually through your school’s portal. This reporting is how the system tracks your compliance, and failing to report can cause problems. Keep records of your employment, including offer letters, pay stubs and job descriptions.
The STEM OPT Extension
Graduates with degrees in qualifying science, technology, engineering and math fields may apply for an additional twenty-four months of work authorization. The Department of Homeland Security maintains a list of designated STEM fields, identified by classification codes, and your degree must be on it. The extension is attractive because it nearly triples the time you can work after graduation, which can matter greatly for people who plan to apply for work visas or green cards later.
Key STEM OPT requirements
- Your degree must be in a designated STEM field, either from the degree you just completed or, in some cases, from a prior degree.
- Your employer must be enrolled in E-Verify, a government system for confirming work eligibility.
- You and your employer must complete a training plan, on Form I-983, describing how the job will provide practical training related to your degree, with learning objectives and supervision.
- The job must be at least twenty hours per week and the employer must provide compensation comparable to similar U.S. workers.
- The employer can’t be a placement company that merely supplies workers to other firms, and the training must happen under the employer’s supervision.
Applying for the extension
You file the STEM OPT application before your initial OPT expires, within a window that starts ninety days before the end date and must be submitted before the existing authorization ends. Your DSO issues a new I-20 with the STEM OPT recommendation, and you file Form I-765 with USCIS. In many cases, a timely filing allows you to continue working for a limited period while the application is pending, but the rules and conditions are technical, so confirm exactly how this works for your case with your DSO.
Ongoing obligations on STEM OPT
STEM OPT carries additional responsibilities. You must submit periodic evaluations, typically at the one-year mark and at the end, and you must report changes to your employment and training. The employer must also maintain the training plan and report certain changes. These steps are part of the program’s oversight, and neglecting them can create problems.
The Cap-Gap Extension for H-1B
Some graduates on OPT are selected for H-1B sponsorship. The cap-gap extension can help bridge the period between the end of your OPT and the October 1 start of H-1B status. If your employer files a timely and eligible H-1B petition requesting a change of status, your F-1 status and work authorization may be extended automatically until the H-1B takes effect, subject to the current rules. This is an important protection, but it depends on timing and eligibility, so work closely with your employer and DSO.
Traveling During OPT
Travel while on OPT requires planning. If you leave the U.S. and your OPT application is still pending, you may have trouble returning in some cases, and if you leave while on approved OPT you’ll generally need your valid passport, a valid F-1 visa stamp, your EAD card, your I-20 with a recent travel signature and, ideally, proof of employment or a job offer. If your visa stamp has expired, you’ll need to renew it abroad, and that can involve scrutiny and delays. Always consult your DSO before international travel.
Common Mistakes That Can End OPT
- Working before the card’s start date. Even a day early is a violation.
- Missing the filing window. Applications outside the ninety-days-before to sixty-days-after window are not accepted.
- Exceeding ninety days of unemployment. Track your days carefully.
- Taking unrelated work. Your job must be connected to your degree.
- Failing to report changes. Address, employer and status updates must be reported on time.
- Using pre-completion OPT without realizing the effect. It reduces your post-completion time.
- Ignoring STEM OPT requirements. The employer’s E-Verify enrollment and the training plan are mandatory.
- Relying on outdated advice. Rules and procedures change, so confirm current details.
Planning Beyond OPT
OPT is a bridge, not a permanent solution. Use the time to build experience, explore sponsorship options and plan your next steps. Possible paths include an H-1B petition from your employer, another degree program, an O-1 if you have extraordinary achievements, a transfer to an overseas office of a multinational employer followed by an L-1 later, or a self-petitioned green card route if you qualify. Because the H-1B lottery isn’t guaranteed, the more years you have on STEM OPT, the more chances you may get to participate. Think about your long-term plan early, and speak with your employer about their willingness to sponsor.
The Bottom Line
OPT is a rare chance to turn a degree into real American work experience, and the STEM extension makes it even more powerful. But its rules are precise: apply within the window, wait for your card, keep working in your field, stay within the unemployment limit and report every change. Build a close relationship with your school’s international office, keep your documents organized and treat each deadline as final. Handled carefully, OPT can be the launch pad for the career you came to the United States to build.
