1. What Is the F-1 STEM OPT Extension?
The STEM OPT (Science, Technology, Engineering, and Mathematics Optional Practical Training) extension is a 24-month addition to the standard 12-month post-completion OPT. It allows F-1 students who have earned degrees in specific STEM fields to gain additional work experience in the U.S.
Total Possible OPT: 12 months (initial) + 24 months (STEM extension) = 36 months.
Purpose: To provide practical training directly related to the student's qualifying STEM degree.
Legal Basis: Governed by U.S. Citizenship and Immigration Services (USCIS) regulations

2. Who Is Eligible for STEM OPT?
You have to meet all of the following criteria:
Current Status: Be in an active period of post-completion OPT.
STEM Degree: Hold a bachelor’s, master’s, or doctoral degree from an accredited U.S. institution in a field on the DHS STEM Designated Degree Program List.
To qualify as an employer the company you work for needs to be signed up for and actually using E-Verify.
The job has to pay you because unpaid work does not follow the rules, for STEM.
The job also has to be related to the STEM degree you have.
Previous STEM Degrees: If you already have a STEM degree from a university in the United States you might be able to use it. This STEM degree can be from an university or a university you attended before. The main thing is that the university has to be good enough and the STEM degree has to be, on the list.
Application Timing: File your I-765 application before your current 12-month OPT expires, and within 60 days of your DSO’s recommendation in your SEVIS record.
3. STEM OPT Employer Requirements
E-Verify enrollment required
Completion of Form I-983 (Training Plan)
Ongoing supervision and evaluation
Must not replace U.S. workers
4. Application Timeline
This is really bad: the main reason people get denied is because they miss their deadlines. Missing deadlines is a problem and it is the most common reason for denial. When you miss a deadline it can cause a lot of trouble. That is why missing deadlines is the number one reason, for denial.
The earliest date you can send in your application to the United States Citizenship and Immigration Services is 90 days before your current Optional Practical Training Employment Authorization Document expires. You can file your application with the USCIS 90 days before your OPT EAD expires.
Latest Filing Date: USCIS must receive your application before your current OPT EAD expires.
Processing Time: Can take 3-5 months. You can continue working for up to 180 days after your OPT expires while the extension is pending, as long as you filed on time.
5. Work & Reporting Rules
You have to make sure you keep track of what's going on by reporting everything that happens. This is something you have to do yourself it is your job to maintain the status of things through reporting. You are personally responsible, for this, which means you have to take care of it and make sure it gets done.
Validation Reporting: Report to your DSO every 6 months (starting from your STEM OPT start date), confirming your personal and employment information is correct.
If there is a change of information you need to tell your DSO about it. You have to do this within 10 days. This means you have to report things like:
Change in legal name, residential/mailing address, or employer.
Loss of employment (you have a 90-day cumulative unemployment limit during the total 36-month OPT period) Any significant reduction in hours, change in supervisor, or deviation from the I-983.
Self-Evaluations: Submit a formal self-evaluation to your DSO at the 12-month and 24-month points (and at the end of employment if earlier). Your employer must sign these.
6. Common Mistakes That Cause Status Violations
Missing Reporting Deadlines: Failing the 6-month validation or 10-day change reports.
Exceeding Unemployment: Going over 90 days of unemployment during the entire OPT period (150 days for the 24-month extension portion).
Working for a Non-E-Verify Employer.
Failing to Update the I-983: Not submitting a new I-983 for any "material change" in employment (e.g., new job, significant role change).
Letting the Application File Late: Mailing the application too close to the OPT expiry date.
7. Traveling During STEM OPT
Required Documents: A valid (unexpired) F-1 visa, EAD card (for STEM OPT, this is the combo card or the standalone STEM EAD), a job offer letter or employment verification, and a valid Form I-20 with a travel signature less than 6 months old.
Pending Application: It is risky to travel while your STEM OPT application is pending. If you leave, USCIS may consider the application abandoned, or you may not be able to re-enter without the new EAD.
Final Takeaway
The STEM OPT extension is a valuable opportunity, but it comes with significant shared responsibility between you, your employer, and your school's international office. Success depends on:
To make a plan you should start working on the I-983 and the application process really early. This way you can get everything done on time. Avoid any last minute rush, with the I-983 and application.
Meticulous Record-Keeping: Keep copies of every form, report confirmation, and correspondence.
Constant Communication is really important. We need to keep talking to our Dental Support Organization. If we are not sure about something we should tell them. Ask for help. This way we can make sure everything is okay, with our Dental Support Organization.
Vigilance: Treat your immigration status as a top priority. Set calendar reminders for all reporting deadlines.
Good Luck
