STEM OPT (Science, Technology, Engineering, and Mathematics Optional Practical Training extension) is a 24-month extension of the standard 12-month Optional Practical Training (OPT) program available to F-1 students who earned a qualifying STEM degree from an accredited US institution. Combined with regular OPT, STEM students can work lawfully in the US for up to 36 consecutive months — long enough to participate in the H1B lottery up to three times.
The program is authorized under 8 CFR § 214.2(f)(10)(ii)(C) and was significantly expanded by the 2016 DHS final rule, which replaced the prior 17-month STEM OPT extension with the current 24-month period. The expanded STEM OPT program added new requirements including mandatory employer E-Verify participation and the formal I-983 training plan, designed to ensure students are gaining genuine training in their field of study.
STEM OPT is an EAD (Employment Authorization Document) — the physical card issued by USCIS that authorizes you to work for any qualifying E-Verify employer in your field. Unlike H1B, STEM OPT is not employer-specific in the sense that you can change employers (with proper DSO notification and updated I-983), but the E-Verify requirement effectively limits you to larger, more established employers who have enrolled in the federal employment verification program.
Not all OPT holders are eligible for the STEM extension. You must satisfy all of the following requirements simultaneously. If you fail any single requirement, you cannot receive the extension — there are no waivers or exceptions for most of these criteria:
Your degree must appear on the DHS STEM Designated Degree Program List, identified by CIP code. Computer Science (11.07xx), Computer Engineering (14.09xx), Electrical Engineering (14.10xx), Mechanical Engineering (14.19xx), Mathematics (27.xx), Statistics (27.05xx), and Biological Sciences (26.xx) commonly qualify. Your DSO can confirm whether your specific degree program's CIP code is on the list.
The school that granted your STEM degree must be SEVP-certified (Student and Exchange Visitor Program) and accredited by a federally recognized accrediting agency. Foreign degrees, degrees from non-SEVP schools, and degrees from unaccredited institutions do not qualify, even if the field of study would otherwise be eligible.
You must be on initial OPT (12-month post-completion OPT) with a currently valid EAD at the time you apply for the STEM extension. You cannot apply retroactively after your OPT expires. Filing must occur while your OPT is still valid — the 'timely filed' rule only applies if you file before expiration.
Your employer must have an active E-Verify company ID, not just a pending enrollment. You can check employer E-Verify status at e-verify.uscis.gov/emp-search. The E-Verify requirement applies to each employer you work for on STEM OPT — if you change employers, the new employer must also have active E-Verify.
The position must involve practicing or training in your STEM field. Your I-983 Training Plan must clearly explain how the job duties relate to your degree. A computer science graduate working as a software engineer clearly qualifies; the same graduate working in an unrelated business role likely does not, even if the employer is technically a technology company.
STEM OPT generally requires full-time or substantial part-time employment. The E-Verify requirement effectively creates a full-time work expectation since E-Verify cases require formal employment verification. Unpaid internships, purely stipend-based positions, or remote work for foreign companies do not satisfy the STEM OPT employment requirement.
You can only receive one STEM OPT extension per qualifying degree. If you used a STEM OPT extension for your Bachelor's degree and then earned a Master's in a different STEM field, you may qualify for a second STEM OPT period based on the new degree. However, you cannot receive two STEM OPT extensions for the same degree from the same institution.
The STEM OPT application process involves coordination between you, your employer, and your DSO at your university. Start the process at least 90 days before your current OPT expires — this is both a requirement and a practical necessity given USCIS processing times. Here is the complete step-by-step process:
STEM OPT extension is only available for degrees in fields on the DHS STEM Designated Degree Program List. Common qualifying fields: Computer Science, Engineering, Mathematics, Statistics, Biological Sciences, Physics, Chemistry, Information Technology, Data Science. Check the full list using your CIP code (Classification of Instructional Programs) at ICE.gov/SEVIS.
Your employer must participate in E-Verify before you can begin STEM OPT. You can verify your employer's E-Verify status at e-verify.uscis.gov/emp-search. If your employer doesn't have E-Verify, you must either ask them to enroll (it's free and takes about a week) or find a new employer who already participates. This step cannot be skipped or waived.
At least 90 days before your current OPT ends, visit your international student office (DSO — Designated School Official) with your job offer documentation. Your DSO issues a new I-20 with a STEM OPT recommendation for a 24-month extension. Without the updated I-20, you cannot file Form I-765.
You and your employer must complete Form I-983 — the STEM OPT Training Plan. This document defines your learning objectives, describes how the job relates to your STEM degree, includes a formal self-evaluation schedule, and identifies the knowledge and skills you will develop. Your DSO reviews and approves the I-983 before you file.
File USCIS Form I-765 with your updated I-20, current EAD, Form I-983, employer E-Verify documentation, and filing fee ($520 as of 2025). File at least 90 days before your OPT expires — timely filing allows you to continue working even if the STEM OPT hasn't been approved yet, through an automatic 180-day extension bridge.
USCIS will mail your new 24-month STEM OPT EAD to the address on your application. As long as you filed on time and your current OPT hasn't expired, you can continue working while the application is pending. Regular processing takes 3–5 months; premium processing is not available for EAD applications.
If you file your I-765 STEM OPT application on time (before your current OPT EAD expires), USCIS automatically extends your work authorization for up to 180 days while the application is pending. This means you can continue working continuously from initial OPT into STEM OPT without any gap, even if USCIS takes longer than expected to process your application. Keep a copy of your I-765 receipt notice as proof of the automatic extension.
The most important strategic reason to get STEM OPT is to maximize your H1B lottery chances. With 36 total months of work authorization (12 OPT + 24 STEM OPT), you have up to three chances to be selected in the H1B lottery. Given that the FY2025 lottery selection rate was only 18.1%, having three attempts dramatically improves your cumulative probability of selection. Here is the optimal multi-year strategy:
Graduate and start your 12-month OPT. Apply for H1B in the March lottery for an October 1 start date. Even if not selected, you have time — your STEM extension provides two more chances. Use this year to build skills, establish yourself with an employer willing to sponsor H1B, and confirm your employer has E-Verify for your upcoming STEM OPT application.
Apply for STEM OPT extension before your initial OPT expires (file 90+ days before expiration). Once approved, continue working. Apply in the March H1B lottery again. If selected, file the full I-129 petition with your employer. If not selected, you still have one more year of STEM OPT and one more lottery attempt remaining.
Your third and final lottery attempt. If selected in this year's lottery, cap-gap automatically extends your STEM OPT authorization from your STEM OPT expiration date through September 30, ensuring you can work continuously from STEM OPT directly into H1B on October 1. If not selected in three lottery attempts, consider EB-1C/O-1 alternatives, cap-exempt employment, or continuing education.
Once your H1B is approved and effective October 1, your status changes from OPT/STEM OPT (F-1) to H1B. Your EAD is no longer valid — your I-797 H1B approval notice and I-94 are your work authorization documents. You can now begin the green card process (PERM, I-140, I-485) without any risk to your immigration status.
At the FY2025 selection rate of 18.1%, having three independent lottery attempts dramatically increases your cumulative odds of being selected at least once:
18.1%
After 1 attempt
32.9%
After 2 attempts
45.1%
After 3 attempts
Calculated assuming independent selections at 18.1% probability each. Actual rates vary by year and by whether you qualify for the master's cap.
The STEM OPT regulatory landscape has been active in recent years, with legal challenges, policy updates, and administrative changes affecting how the program operates. Here is what you need to know for 2026:
The STEM OPT program has faced repeated legal challenges since its 2016 expansion from 17 to 24 months. As of 2026, the program remains in place under current DHS regulations. However, the regulatory environment can change with new administrations or court decisions. Always confirm with your DSO and an immigration attorney that the program status has not changed before making major career or financial decisions that depend on STEM OPT authorization.
USCIS does not offer premium processing for Form I-765 (EAD applications), including STEM OPT extensions. Regular processing for STEM OPT extensions typically takes 3–5 months. This is why the 90-day advance filing requirement and the 180-day automatic extension bridge exist — to protect you from work authorization gaps during processing. Always file as early as possible (at the 90-day mark) and keep your I-765 receipt notice as proof of the automatic extension period.
The E-Verify requirement for STEM OPT employers has remained unchanged since the 2016 rule. Employers must be enrolled in and actively using E-Verify throughout your STEM OPT period. If your employer terminates their E-Verify enrollment while you are on STEM OPT, you are in violation. Exceptions for employers who acquired another company are narrowly applied and require immediate legal guidance.
USCIS increased its fee schedule in 2024. The current Form I-765 filing fee is $520 (up from $410). This fee applies to STEM OPT extension applications. There is no employer obligation to pay this fee — it is typically paid by the student/applicant. Fee waivers are not available for STEM OPT applications. Confirm the current fee at uscis.gov/feeschedule before filing, as fees can change.
STEM OPT and H1B both provide work authorization in the US, but they are fundamentally different in terms of legal basis, employer obligations, portability, and long-term implications. Understanding these differences helps you plan the optimal strategy for your immigration journey:
| Feature | STEM OPT | H1B |
|---|---|---|
| Duration | 24 months (+ 12 months regular OPT) | 3 years initial, 3-year extension (6 years total) |
| Immigration status | F-1 student status | Non-immigrant worker status |
| Employer requirement | Any E-Verify enrolled employer in STEM field | Specific sponsoring employer; must file I-129 per employer |
| Employer portability | Can change employers with 10-day DSO notice + new I-983 | Requires new I-129 petition; AC-21 portability after 180 days |
| Green card path | No direct green card pathway; must transition to H1B or other visa | Explicit dual intent; can file PERM/I-140/I-485 simultaneously |
| Spouse work authorization | F-2 dependent spouse cannot work | H-4 EAD available after I-140 approval |
| Cost to employee | $520 I-765 filing fee + attorney (if used) | Employer typically pays most fees; may involve premium processing |
| Annual cap/lottery | No cap or lottery | 85,000 annual cap; random lottery |
The key takeaway: STEM OPT is excellent for gaining work experience and participating in the H1B lottery, but it is a temporary bridge — not a permanent solution. The moment you are selected in the H1B lottery, transition to H1B to gain the dual-intent protections and green card pathway that H1B provides.
The E-Verify requirement means STEM OPT students need to find employers who are enrolled in the federal employment verification system. Virtually all large US technology companies, major consulting firms, and financial institutions are enrolled in E-Verify. Here are some of the most active STEM OPT employers across industries, all with active E-Verify participation:
| Employer | Industry | E-Verify | Notes |
|---|---|---|---|
| Amazon | Technology / Cloud | Active | Active E-Verify; large STEM OPT hiring across SDE, data, ML roles |
| Google / Alphabet | Technology / AI | Active | Strong STEM OPT program; sponsors majority of technical interns to full-time |
| Microsoft | Technology / Cloud | Active | Active E-Verify; extensive immigration support including STEM OPT and H1B |
| Meta | Technology / Social | Active | Active E-Verify; sponsors STEM OPT across engineering, data science, research |
| Apple | Technology / Consumer | Active | E-Verify enrolled; strong STEM OPT pipeline in hardware, software, ML |
| Deloitte | Consulting / Technology | Active | Large E-Verify employer; STEM OPT common for technology consulting analysts |
| JPMorgan Chase | Finance / Fintech | Active | E-Verify enrolled; sponsors STEM OPT for technology and quant roles |
| Nvidia | Semiconductors / AI | Active | Active E-Verify; major STEM OPT employer given AI/GPU talent demand |
| Salesforce | Enterprise SaaS | Active | E-Verify enrolled; sponsors STEM OPT across software engineering and data |
| IBM | Technology / Consulting | Active | Active E-Verify; strong STEM OPT program with H1B pathway for research roles |
Beyond the major tech companies, thousands of mid-size companies, government contractors, research organizations, and consulting firms also have active E-Verify enrollment. Use the USCIS E-Verify employer search tool at e-verify.uscis.gov/emp-search to verify any specific employer before accepting an offer. You should confirm E-Verify status before signing an offer letter — discovering a lack of E-Verify after you've already declined other offers can create difficult situations.
While STEM OPT denials are not common when applications are properly prepared, they do occur. The most common denial reasons are filing after OPT expires, non-qualifying employer (no E-Verify), non-qualifying degree program (not on DHS STEM list), and incomplete I-983 or I-20 documentation. Here is what to do if you receive a denial:
A STEM OPT denial has serious time-sensitive consequences. Once denied, you have a 60-day grace period (as an F-1 student) from the date of denial to either depart the US, transfer to a new SEVIS record, or change to a different non-immigrant status. Do not delay — contact an attorney the same day you receive the denial notice.
The denial notice will specify the reason(s) for denial. Some reasons (like a documentation error) may support a Motion to Reopen (I-290B) if USCIS made an error. Other reasons (like applying after OPT expiration) are not correctable. Your attorney will assess whether a motion is viable.
If the denial was based on a USCIS error or a legal/factual misapplication, you can file Form I-290B (Motion to Reopen or Reconsider) within 33 days of the denial. This is a complex legal filing and should only be done with attorney assistance. Note that filing a motion does not automatically extend your work authorization.
If the denial cannot be corrected, explore alternatives: (1) Can you transfer to a different school that would give you a new SEVIS record and restart OPT? (2) Can your employer sponsor an H1B cap-exempt petition if they are a qualifying institution? (3) Is there another non-immigrant status (O-1A for individuals with extraordinary ability, J-1 for certain research roles) that applies? (4) Could you pursue a second STEM degree at a different degree level?
STEM OPT itself does not provide a direct path to a green card — it is F-1 student status, which is explicitly non-immigrant. However, STEM OPT is a critical stepping stone in the most common immigration journey for international STEM graduates: OPT → STEM OPT → H1B → PERM → I-140 → I-485 → Green Card. Here is how the full pathway works:
12 months F-1 OPT
24 months F-1 STEM OPT
Lottery → October 1 start
Dual intent, 3 years
6–18 months
Immigrant petition
Adjustment of Status
Permanent Resident
The total timeline from graduation to green card depends heavily on your country of birth and the relevant employment-based preference category. For most Indian nationals in EB-2 or EB-3 categories, the priority date backlog means the I-485 stage can be decades away. For nationals of most other countries, the entire process from H1B to green card can take 3–7 years.
One important strategic note: file your PERM labor certification as soon as possible after getting your H1B approved. Your PERM priority date (the date your PERM application was filed with the Department of Labor) determines your place in the green card queue. Every year of delay means a year longer wait. Even if you're not certain you'll stay long-term, filing PERM early preserves your option to pursue a green card later.
STEM OPT has more compliance requirements than regular OPT. Violations can result in loss of your F-1 status, which triggers an immediate requirement to leave the US or change to another valid immigration status. Here are the most critical mistakes to avoid:
Working for employer without active E-Verify
Not filing I-765 extension before OPT expires
Failing to update DSO within 10 days of employer change
Having more than 150 cumulative days of unemployment
Not completing or updating Form I-983 when required
Working in a role unrelated to your STEM degree
Employer terminates E-Verify enrollment mid-STEM OPT
Failing to report address change to SEVIS within 10 days
Working part-time under 20 hours per week consistently
Not reporting a layoff or job loss to DSO promptly
Severity: Red = can result in immediate status violation; Orange = serious compliance issue requiring immediate correction; Yellow = should be corrected promptly to avoid escalation.
