STEM OPT Extension: Eligibility, Application, Benefits

What is STEM OPT Extension

STEM OPT extension is a 24-month extension of post-completion Optional Practical Training (OPT) for F-1 students who have earned a qualifying degree in Science, Technology, Engineering, or Mathematics from a US university.

OPT itself is a work authorization that allows F-1 students to work in the USA in a job related to their field of study. The standard OPT period is 12 months. STEM OPT extends this by an additional 24 months – giving eligible students a total of 36 months of authorised work experience.

• STEM OPT is not a visa. It is a work authorization under your existing F-1 student status.
• It is administered by USCIS (US Citizenship and Immigration Services) and DHS (Department of Homeland Security).
• It is available once per qualifying degree level – meaning you can receive it twice in your academic career if you earn qualifying STEM degrees at two different levels (for example, a Bachelor's and then a Master's).
• The maximum total OPT you can accumulate with two STEM extensions across two degree levels is 72 months (12 + 24 + 12 + 24).

STEM OPT Extension Eligibility: Who Qualifies

To qualify for the 24-month STEM OPT extension, you must meet all four of the following conditions simultaneously. Missing any one condition makes you ineligible.

Special eligibility cases confirmed by USCIS:

• Using a prior STEM degree: If you are currently on OPT for a non-STEM degree but previously earned a STEM degree from an accredited SEVP-certified US institution, you may use that prior degree to apply for STEM OPT – provided the prior degree was obtained within the last 10 years, and the practical training is directly related to that STEM degree.
• Second STEM OPT extension: If you later earn a qualifying STEM degree at a higher level (for example, a Master's after a Bachelor's), you are eligible for a second 24-month STEM OPT extension based on the new degree.
• What disqualifies you: You cannot apply during the 60-day grace period after your initial OPT ends. You cannot apply if your employer is not E-Verify enrolled. You cannot apply if your degree is not on the DHS STEM Designated Degree Program List. 

Which Degrees Qualify for STEM OPT Extension

Your degree must appear on the DHS STEM Designated Degree Program List to qualify for the STEM OPT extension. This list is maintained by DHS and uses Classification of Instructional Programs (CIP) codes to identify eligible fields.

The table below lists the most common degree fields that qualify, which are directly relevant to Indian students.

Important: The eligibility is determined by the CIP code assigned to your specific degree program — not just the subject name. Two universities may offer an "MS in Business Analytics," but only one may have a STEM-designated CIP code. Always verify your program's CIP code with your university's international student office (DSO) before assuming STEM OPT eligibility.

How to Apply for STEM OPT Extension?

The STEM OPT extension application involves your DSO (Designated School Official), your employer, and USCIS – in that order. You cannot file directly with USCIS without first completing the DSO and employer steps.

• Step 1: Confirm your degree's STEM eligibility. Check with your DSO that your degree program has a STEM-designated CIP code. Do this at least 4–5 months before your OPT expires.
• Step 2: Confirm your employer's E-Verify enrollment. Ask your employer for their E-Verify Company Identification Number and confirm they have a valid EIN. Without these, you cannot file.
• Step 3: Complete Form I-983 with your employer. Form I-983 is the Training Plan for STEM OPT Students. It must be completed jointly by you and your employer. It describes your learning objectives, how the training relates to your STEM degree, and your employer's supervision plan. Both you and your employer must sign it. Submit the completed I-983 to your DSO.
• Step 4: Request a new STEM OPT I-20 from your DSO. Your DSO reviews the I-983 and, if approved, updates your SEVIS record with the STEM OPT recommendation and issues a new I-20 endorsed for STEM OPT. This I-20 must be dated within the last 60 days when you file with USCIS.
• Step 5: File Form I-765 with USCIS. File online at uscis.gov or by mail. Include your employer's name as listed in E-Verify, their E-Verify Company Identification Number, the filing fee, your new STEM OPT I-20, and a copy of your STEM degree. File no earlier than 90 days before your OPT expires and no later than the OPT expiry date.
• Step 6: Receive your new EAD card. USCIS will issue a new Employment Authorisation Document (EAD) for the 24-month STEM OPT period. If your OPT expires while the application is pending and you filed on time, USCIS automatically extends your work authorization by 180 days.

Note: You must be physically present in the USA to file your STEM OPT application. Do not travel internationally while your STEM OPT application is pending without consulting your DSO first.

Fees and Processing Time in 2026

There are two fee options for the STEM OPT extension application in 2026: standard processing and premium processing.

The premium processing fee increased from $1,685 to $1,780 effective March 1, 2026, as announced by USCIS. Premium processing guarantees a decision within 30 business days – it does not guarantee approval.

• Standard processing in 2026 is taking 90–150 days based on reported timelines from the r/f1visa and r/USCIS communities.
• If you file on time (before OPT expiry) and your OPT expires while the application is pending, USCIS automatically extends your work authorization for 180 days. This 180-day extension ends the moment USCIS decides on your application.
• Premium processing is worth considering if your OPT expiry is within 90 days and you cannot afford a gap in work authorisation.

Important: The filing fee is non-refundable. If your application is denied, you do not get the fee back.

Employer Requirements: What Your Company Must Do

Your employer carries significant legal obligations under the STEM OPT program. Many Indian students discover too late that their employer does not meet the requirements, which results in a denied application or loss of work authorization.

The following are the mandatory employer requirements as confirmed by USCIS:

• Must be enrolled in E-Verify and in good standing with a valid E-Verify Company Identification Number.
• Must have a valid Employer Identification Number (EIN) issued by the IRS.
• Must complete and sign Form I-983 (Training Plan), which describes the student's learning objectives and how the training relates to their STEM degree.
• Must provide a minimum of 20 hours of work per week.
• Must maintain a bona fide employer-employee relationship with the student – meaning the employer cannot be the student in name only, and the student cannot work on a volunteer basis.
• Must report any material changes to the student's employment (change in role, location, hours) by submitting a modified I-983 to the DSO at the earliest opportunity.
• Must report the student's termination or departure to the DSO within 5 business days.
• Must not use the STEM OPT student to replace a full-time or part-time US worker.

Staffing agencies and consulting firms: These employers may qualify for STEM OPT only if they are the entity that directly provides the practical training and maintains a bona fide employer-employee relationship with the student. If the actual work is performed at a client's site and supervised by the client's staff, the arrangement may not qualify. DHS may conduct site visits to verify compliance.

A critical note from students navigating this: "Many Indian students work at consulting firms that place them at client sites. The key question USCIS asks is: Who is actually training you? If it's the client and not your employer, your I-983 may be rejected."

Reporting Responsibilities During STEM OPT

STEM OPT comes with strict ongoing reporting obligations. Failing to report changes on time can jeopardise your F-1 status — not just your STEM OPT.

You must report the following changes to your DSO within 10 days of the change occurring:

• Your legal name
• Your residential or mailing address
• Your email address
• Your employer's name
• Your employer's address

In addition, you must report to your DSO every 6 months to confirm the above information – even if nothing has changed. This is a mandatory check-in, not optional.

If you change employers during STEM OPT, you must submit a new Form I-983 signed by your new employer to your DSO. The new employer must meet all STEM OPT requirements. You cannot begin working for the new employer until the new I-983 is submitted and your DSO has updated your SEVIS record.

Note: Your post-completion OPT employer does not need to be the same as your STEM OPT employer. You can change jobs, but the new employer must be E-Verify enrolled and willing to complete the I-983.

Unemployment Rules: How Many Days You Can Go Without Work

Exceeding the unemployment limit during OPT or STEM OPT is one of the most common ways Indian students inadvertently fall out of F-1 status. The rules are strict and the days accumulate even on weekends.

• The 90-day and 60-day limits are cumulative across the entire OPT and STEM OPT period – not per year.
• Weekends and holidays count as unemployment days if you are not employed.
• The period between jobs (while actively searching) counts as unemployment days.
• If you exceed 150 total days of unemployment across both periods, you violate your F-1 status.

Benefits of STEM OPT Extension for Indian Students

The STEM OPT extension is the single most valuable post-graduation benefit available to Indian F-1 students in the USA. Here is why it matters beyond just the extra work time.

• 36 months total in the US job market: The combination of 12-month OPT and 24-month STEM OPT gives you three full years to build your career, develop skills and pursue H-1B sponsorship — without needing a work visa.
• Three H-1B lottery chances: The H-1B lottery runs every April for an October 1 start date. With 36 months of OPT and STEM OPT, you get three separate lottery cycles to be selected. This significantly improves your odds compared to the single chance available on standard 12-month OPT.
• Cap-gap protection: If you are selected in the H-1B lottery while on STEM OPT, the cap-gap provision automatically extends your F-1 status and work authorisation from the date your STEM OPT expires until October 1 (the H-1B start date). This prevents any gap in your legal status.
• Salary and career growth: Three years of US work experience in a STEM field significantly strengthens your profile for H-1B sponsorship, green card applications and long-term career advancement.
• Second STEM OPT if you earn a higher degree: If you complete a Master's after a Bachelor's (or a PhD after a Master's), you are eligible for a second 24-month STEM OPT extension — giving you up to 72 months of total OPT across your academic career.

Important context for 2026: A US House bill introduced on April 22, 2026 proposed eliminating the OPT program entirely. As of May 2026, OPT has not been eliminated and remains fully operational. However, Indian students should stay informed about legislative developments. Read our guide on the OPT Program 2026: Rules, Risks and Alternatives for Indian Students.
