What Is STEM OPT? 24-Month Extension Explained

The Short Answer

STEM OPT is a 24-month extension of the standard 12-month Optional Practical Training (OPT) period available to F-1 students who earned a degree in a qualifying science, technology, engineering, or mathematics (STEM) field. It is administered by the Department of Homeland Security through USCIS and the Student and Exchange Visitor Program (SEVP), and it allows STEM graduates to work in their field of study for up to 36 months total (12 months of standard OPT plus 24 months of STEM OPT) after graduation. STEM OPT exists because U.S. policymakers have decided that STEM graduates trained at U.S. universities add enough value to justify a longer work authorization period than other F-1 graduates receive.

STEM OPT has strict eligibility rules, additional employer obligations, and a detailed training plan requirement that distinguish it from standard post-completion OPT. Understanding these rules is essential for both F-1 students and their employers.

Who Qualifies for STEM OPT?

To be eligible for STEM OPT, an F-1 student must meet several requirements:

1. Currently on approved standard post-completion OPT. The student must be in their first 12-month OPT period based on a U.S. degree.
2. Degree in a qualifying STEM field. The degree must be on the current DHS STEM designated degree list, which is maintained and updated periodically. The list includes specific CIP codes — not every scientific or technical degree qualifies, so students must verify their specific degree's CIP code against the current list at ice.gov/sevis/stemlist.
3. Degree from an accredited U.S. school. The school must be accredited by an entity recognized by the U.S. Department of Education and must be SEVP-certified.
4. Employer enrolled in E-Verify. The employer offering STEM OPT employment must be enrolled in E-Verify, the government's employment eligibility verification system.
5. Job relates to the STEM degree. The STEM OPT work must be directly related to the student's STEM degree — not just tangentially related.
6. Formal training plan. The student and employer must complete Form I-983, Training Plan for STEM OPT Students, describing the practical training the student will receive.

The Training Plan: Form I-983

Form I-983 is a key distinguishing feature of STEM OPT. It is a detailed document signed by the student and an authorized representative of the employer, laying out:

• The student's role and job duties.
• How the role relates to the STEM degree.
• The learning objectives the student will achieve during STEM OPT.
• How the student will be supervised and evaluated.
• The student's salary and hours.
• The employer's commitment to provide meaningful work.

The training plan is submitted to the student's Designated School Official (DSO) at the school where they earned their degree. The DSO updates the student's SEVIS record to reflect the STEM OPT status. Form I-983 is not submitted directly to USCIS with the I-765 application, but the student should retain a copy and be prepared to produce it on request.

How to Apply: Form I-765

STEM OPT is requested on Form I-765, Application for Employment Authorization, with eligibility category (c)(3)(C) — the code specific to STEM OPT. The application must be filed while the student is still in their standard OPT period and within 60 days of the DSO recommending STEM OPT in SEVIS. The basic steps:

1. Work with the DSO to request STEM OPT recommendation in SEVIS. The DSO updates the student's I-20 with the STEM OPT recommendation.
2. Complete the I-983 training plan with the employer.
3. File Form I-765 with USCIS, including the updated I-20, evidence of the STEM degree, and the I-765 filing fee.
4. Wait for USCIS adjudication. Processing times vary; check USCIS current processing times at egov.uscis.gov/processing-times.
5. Receive the new EAD. If approved, USCIS mails a new Employment Authorization Document showing the STEM OPT period.

The STEM OPT EAD authorizes work for the specific employer listed in the training plan. Changing employers during STEM OPT requires filing a new I-983 and updating SEVIS.

Employer Obligations Under STEM OPT

STEM OPT imposes obligations on employers beyond what ordinary OPT requires:

• E-Verify enrollment. The employer must be enrolled in and using E-Verify.
• Training plan commitment. The employer signs Form I-983 committing to provide the specific training described.
• Reporting changes. The employer must notify the student's DSO of material changes like termination, resignation, reduction in hours, or significant changes in duties.
• Self-evaluation forms. The student must submit a self-evaluation at 12 months and a final self-evaluation at the end of STEM OPT, both requiring employer acknowledgment.
• Wage and work conditions. STEM OPT employment must be paid employment that is commensurate with the terms and conditions for similar U.S. workers. Unpaid internships do not qualify.
• Site visits. DHS may conduct site visits at the employer's location to verify that the STEM OPT training is being provided as described.

Unemployment Limits

F-1 students on standard OPT may have up to 90 days of unemployment during the 12-month OPT period without losing status. STEM OPT students have an additional 60 days of unemployment during the 24-month STEM OPT period, for a cumulative total of 150 days of unemployment across the full 36 months. Exceeding the unemployment limit causes loss of F-1 status.

"Unemployment" during OPT means any day on which the student is not authorized to work, not working, and not making progress toward approved work. Students must track their unemployment days carefully.

Reporting Requirements

STEM OPT students have ongoing reporting requirements that must be met to maintain status:

• Address updates within 10 days of any change.
• Employer updates within 10 days of any change in employment.
• 12-month evaluation — self-evaluation submitted through the school.
• 24-month final evaluation — final self-evaluation at the end of STEM OPT.
• Validation reports every six months confirming the student's name, address, employer information, and continued STEM OPT status.

Failing to file these reports can result in loss of F-1 status.

STEM OPT and H-1B Transition

Many STEM OPT students use the extended OPT period to pursue H-1B sponsorship through an employer. The 36-month total OPT window (12 months of regular OPT plus 24 months of STEM OPT) provides flexibility to participate in two or three H-1B lotteries before the work authorization expires. If the student is selected in the H-1B lottery, the "cap gap" provision automatically extends F-1 status and OPT until the October 1 start date of the fiscal year if the H-1B petition is filed on time.

What Ends STEM OPT

STEM OPT can end for several reasons:

• Expiration of the 24-month period.
• Loss of F-1 status due to unemployment exceeding the limit.
• Failure to report required information.
• Termination of employment without a qualifying replacement.
• Travel abroad without proper documentation.
• Violations of the training plan or program rules.
• Change of status to another visa category.

The Bottom Line

STEM OPT is a 24-month extension of F-1 post-completion OPT for students with qualifying STEM degrees. It requires a qualifying degree on the DHS STEM list, an E-Verify employer, a formal I-983 training plan, and ongoing reporting. The extended work authorization period provides more opportunities for H-1B sponsorship and career development in the U.S. For current STEM OPT rules, always check the USCIS and ICE websites, and work with your school's DSO and a licensed immigration attorney for any complex questions.

When to Work with an Immigration Attorney

Not every immigration question needs a lawyer, but some do. The topics covered in this article include situations where a brief consultation with a licensed U.S. immigration attorney can save months of delay, prevent irreversible mistakes, and identify options you might not otherwise know about. Consider consulting an attorney if your case involves any of the following:

• Criminal history of any kind. Even dismissed charges, expunged records, or decades-old offenses can affect immigration outcomes. The immigration consequences of a criminal record are technical and fact-specific, and plea deals that seemed favorable in criminal court sometimes have devastating immigration consequences.
• Past immigration violations or denials. Prior visa denials, overstays, periods of unlawful presence, and prior removal proceedings all affect current options. An attorney can review your history and identify which paths remain open.
• Complicated family situations. Divorce, death of a petitioner, domestic abuse, and similar circumstances can trigger waiver eligibility or affect existing petitions in ways that require careful legal analysis.
• Business immigration matters. Employment-based cases, investor visas, and self-petitions are typically too complex for do-it-yourself filing. The evidentiary standards are demanding and the stakes are high.
• Cases that feel stuck. If your case has been sitting without action for a long time, or if you received an RFE or NOID you do not fully understand, an attorney can diagnose the problem and respond effectively.
• Anything you do not fully understand. Immigration forms are technical, and a small mistake can cascade into large consequences. When in doubt, ask someone qualified.

Finding Reliable Information

The single most reliable source of current U.S. immigration information is USCIS itself. USCIS publishes form instructions, fee schedules, processing times, policy manuals, and policy alerts at uscis.gov. When any article (including this one) references specific fees, processing times, or eligibility rules, the information can become outdated as USCIS updates its policies and fee schedules. Always verify any time-sensitive detail directly with USCIS before filing anything.

Other reliable primary sources include the U.S. Department of State (for visa bulletins and consular processing), the U.S. Department of Labor (for PERM and prevailing wage information), U.S. Customs and Border Protection (for admission and port of entry rules), and the Executive Office for Immigration Review (for immigration court procedures).

Secondary sources — including practitioner guides, law school immigration clinics, and reputable nonprofit legal aid organizations — can provide helpful explanations of how the rules apply in practice. Community forums and social media should be treated with caution: they can point you to useful resources, but they also contain a great deal of inaccurate or outdated information, and the rules change frequently enough that what was true a year ago may not be true now.

Keeping Records

One of the simplest ways to protect yourself through any immigration process is to keep careful records of everything. Copies of every filing you send to USCIS, every notice you receive, every check or money order you submit, and every piece of correspondence you send or receive become critical evidence if something goes wrong later. Keep these records organized, dated, and backed up in at least two separate places (for example, a physical folder and a digital scan).

Also keep records of everything that supports your underlying eligibility — tax returns, marriage certificate, birth certificates, medical records, employment records, property records, school transcripts, and anything else that demonstrates ties to the United States, family relationships, or program eligibility. Good records are the backbone of a strong immigration case.
