OPT for F-1 Students: Timeline, STEM Extension and Common Mistakes

OPT is temporary employment that must be directly related to your major area of study. There are two types. Pre-completion OPT happens while you are still in school: part-time (up to 20 hours per week) while classes are in session, or full-time during official breaks. Post-completion OPT happens after you finish your program, and it can be part-time or full-time.

You can receive up to 12 months of OPT for each higher level of education. For example, you may get 12 months after a bachelor's degree and another 12 months after a master's degree. If you use pre-completion OPT, that time is deducted from the 12 months you have for post-completion OPT.

Here is the key point: OPT is authorized by USCIS through an Employment Authorization Document (EADEADEmployment Authorization Document: the card USCIS issues when work authorization like OPT is approved.), a card that proves you can work. Being an F-1 student does not give you OPT by itself. If you want the bigger picture of on-campus jobs, CPTCPTCurricular Practical Training: work that is an integral part of your curriculum, authorized by your DSO during the program. and OPT, read our guide on whether F-1 students can work in the U.S..

To qualify, you generally must have been lawfully enrolled full-time for one full academic year. USCIS explains that this year does not always need to be in F-1 status, because time in other nonimmigrant statuses can count. You also need to be maintaining your F-1 status and have a job or job plan related to your major.

There is one rule that surprises many students. If you received 12 months or more of full-time Curricular Practical Training (CPT) at the same education level, you are not eligible for post-completion OPT at that level. Part-time CPT does not count against you in this way. If your program uses CPT, plan it carefully and read our CPT guide for F-1 students before you accept a full-time schedule.

This is also why the school and program you choose matter so much. When we help with school placement, we look at whether practical training fits your goals from day one, not only at tuition and location.

The process starts at your school. First, you ask your Designated School Official (DSODSODesignated School Official: the school employee who manages your SEVIS record.), the person at your school who manages F-1 records, to recommend OPT. The DSO enters the recommendation in SEVISSEVISStudent and Exchange Visitor Information System: the government database that tracks F-1 students and their schools. (the government system that tracks F-1 students) and gives you an updated Form I-20I-20Certificate of Eligibility for Nonimmigrant Student Status. An SEVP-certified school issues it, and you need it to apply for the F-1 visa..

Next, you file Form I-765, Application for Employment Authorization, with USCIS. For post-completion OPT, you may file up to 90 days before your program end date and no later than 60 days after it. You must also file within 30 days after your DSO enters the recommendation in SEVIS. Miss either deadline and USCIS can deny your application.

When you apply for post-completion OPT, you request a start date. It must be on or after your program end date and no more than 60 days after it. About the fee: USCIS updates its fee schedule from time to time, so check the current Form I-765 fee on the official USCIS fee page before you file.

Finally, wait for the EAD. You cannot start working, not even one day, before USCIS approves your application and the start date on your EAD arrives. A job offer is not permission to work. Only the EAD is.

Once your post-completion OPT begins, the clock matters. You may not accumulate more than 90 days of unemployment during your initial 12 months of OPT. If you later get the STEM extension, you receive 60 more days, for a total of 150 days across the whole OPT period. SEVIS counts these days based on the employment information in your record.

You also have reporting duties. Report changes to your name, address, employer or employment to your DSO, or through the SEVPSEVPStudent and Exchange Visitor Program: the ICE program that certifies schools to enroll F-1 students. Portal when available, within 10 days. Many students lose track of unemployment days simply because they never reported a new job. Keep your record up to date, and keep copies of offer letters and pay stubs.

If your degree is in science, technology, engineering or math, you may qualify for a 24-month STEM OPT extension. Your degree must appear on the DHS STEM Designated Degree Program List and come from an accredited, SEVP-certified school. Your employer must be enrolled in and using E-Verify, and you and your employer must complete Form I-983, a training plan that explains what you will learn on the job.

You file a new Form I-765 up to 90 days before your current OPT EAD expires, and within 60 days after your DSO enters the STEM recommendation in SEVIS. Do not wait until the last week. If you file on time and your OPT expires while the extension is pending, USCIS automatically extends your work authorization for 180 days. STEM students must also confirm their information with their DSO every 6 months.

Some students who plan to move to an H-1B work visa may also benefit from the cap-gap extension, which can extend F-1 status and work authorization in certain cases while a timely H-1B petition is pending. Eligibility is specific, so confirm it with your DSO and an immigration attorney.

These are some of the most common mistakes. First, filing too late: missing the 30-day window after the DSO recommendation, or the 60-day window after the program end date. Second, writing the wrong mailing address on Form I-765, so the EAD card never arrives. Third, starting work before the EAD start date. Fourth, going over the unemployment limit, often because jobs were not reported. Fifth, accepting a job that is not directly related to your major. Sixth, forgetting to report changes within 10 days.

Rules are also changing, so read recent official updates. DHS published a final rule on July 17, 2026 that replaces "duration of status" with a fixed period of admission for F-1 students, effective September 15, 2026. According to Study in the States, students who need extra time for post-completion OPT or STEM OPT beyond their admission period may need to apply for an extension of stay with USCIS, and the departure period after OPT becomes 30 days instead of 60. Transition rules apply to students admitted before that date. There has also been public discussion about other changes to OPT. As of September 2026, check Study in the States and uscis.gov for the latest before you make plans.

The best time to think about OPT is before you choose a school. We help you find SEVP-certified programs where practical training is part of the plan, and in some programs, depending on the school, CPT or OPT may be available to eligible students. Our OPT and CPT guidance helps you understand the timeline so nothing takes you by surprise.
