Indian students on F-1 status who graduated with a STEM degree can extend their initial 12-month OPT by 24 months, giving them a total of 36 months of work authorization in the USA. This 2026 guide walks through eligibility, employer requirements (E-Verify), application timing, Form I-983 training plan, and common denial reasons — with USCIS as the authoritative source.

What is OPT?

Optional Practical Training (OPT) is temporary employment authorization for F-1 international students to gain practical work experience in their field of study.

  • Pre-completion OPT — during degree (part-time only)
  • Post-completion OPT — after degree completion, 12 months full-time
  • STEM OPT extension — additional 24 months for STEM degree holders

STEM OPT Extension Eligibility

You are eligible for the 24-month STEM OPT extension if:

  1. You are currently on 12-month post-completion OPT
  2. Your most recent degree is in a DHS-approved STEM field (see the STEM Designated Degree Program List on ICE.gov)
  3. You are employed by an E-Verify-registered US employer
  4. Your employer will provide you with a formal training plan (Form I-983)
  5. The training is directly related to your STEM degree
  6. You have not previously used a STEM OPT extension based on the same degree

Employer Requirements for STEM OPT

  • E-Verify enrollment — employer must be enrolled in E-Verify at time of Form I-983 signing
  • Formal training plan — employer completes Form I-983 with detailed training goals + supervision structure
  • Salary and terms — student must be a paid employee (unpaid internships do NOT qualify)
  • Full-time (20+ hours/week) — cannot be a part-time job or 1099 contract
  • Direct STEM-related work — position must relate to student's STEM degree

Form I-983 — Training Plan for STEM OPT

Form I-983 is the mandatory training plan between student + employer, filed with the Designated School Official (DSO):

  1. Student + supervisor complete Form I-983 together
  2. Employer signs training plan committing to specific goals + oversight
  3. Student submits I-983 to DSO for review + approval
  4. DSO issues updated Form I-20 with STEM OPT recommendation
  5. Student files I-765 with USCIS using the updated I-20

Application Timeline

  • 90 days before OPT expiration — earliest you can file I-765 for STEM extension
  • OPT expiration date — file BEFORE this date to preserve status
  • Automatic extension — if USCIS is processing your I-765 when your OPT expires, you get automatic 180-day continued work authorization (not to exceed extension approval)
  • USCIS processing time — 3-5 months typical; can be faster with premium processing
  • Premium processing — available for I-765 STEM OPT; fee currently around $1,685 (verify current)

Practical Application Steps

  1. Confirm your degree is on the DHS STEM list
  2. Verify employer E-Verify enrollment (ask HR or check E-Verify.gov)
  3. Complete Form I-983 with your supervisor
  4. Submit I-983 to your school's DSO
  5. Receive updated Form I-20 with STEM OPT recommendation
  6. File Form I-765 online with USCIS (or paper)
  7. Pay filing fee (verify current — was around $410; may be higher post-fee updates)
  8. Track application via USCIS case tracker
  9. Receive EAD (Employment Authorization Document) card upon approval

Common Denial Reasons

  1. Employer not E-Verify enrolled — automatic denial
  2. Degree not on DHS STEM list — verify CIP code exactly
  3. Position not STEM-related — training plan must show clear relevance
  4. Form I-983 incomplete — training goals + oversight structure must be specific
  5. Late filing — filed after OPT expiration date
  6. Insufficient salary — must meet employer's prevailing wage for the position

Reporting Obligations During STEM OPT

  • 60-day evaluation — Student + supervisor complete evaluations at 12-month and 24-month marks
  • Any change of employer — file new I-983 within 10 days
  • Address changes — update SEVIS within 10 days
  • Job title/duties change — file updated I-983
  • Unemployment period — max 60 days unemployed on STEM OPT (vs 90 days on initial OPT); over that = OPT terminated

Cap-Gap Extension (STEM to H-1B)

If you're on STEM OPT and your employer files H-1B for you:

  • If selected in the lottery + petition pending on Oct 1, you get Cap-Gap extension of F-1 status + OPT until Oct 1
  • Automatic — no separate filing needed
  • DSO must issue updated Form I-20
  • Allows continuous employment authorization while H-1B processes

STEM OPT → H-1B Transition Strategy

  • Year 1 OPT (12 months) — standard post-completion OPT
  • Year 2-3 STEM OPT (24 months) — extension for STEM graduates
  • During Year 2 or 3 — employer files H-1B registration in March lottery
  • If selected + approved — H-1B start on October 1 with Cap-Gap coverage from STEM OPT expiration
  • If NOT selected — try again in next fiscal year (within STEM OPT window)
  • Employer should sponsor for green card (I-140) as early as possible for AC21 §106(a) 3-year H-1B extensions beyond 6-year limit

Frequently Asked Questions

How long is the STEM OPT extension?

24 months — added to the initial 12-month post-completion OPT for a total of 36 months of employment authorization. Only STEM degree holders working for E-Verify-registered employers qualify.

Can I switch employers during STEM OPT?

Yes. Any employer change requires filing a new Form I-983 within 10 days of the switch. The new employer must also be E-Verify enrolled, and the new job must be STEM-related.

What happens if my STEM OPT expires before I get H-1B?

If your employer filed H-1B for you and you were selected in the lottery + petition is pending on October 1, you automatically get Cap-Gap extension of F-1 + OPT until October 1. If not selected, you must depart within your 60-day grace period or transfer to another status.

Is CPT the same as OPT?

No. Curricular Practical Training (CPT) is authorized for internships during your degree program (part of the curriculum). OPT is separate and can be pre-completion (part-time during degree) or post-completion (after degree). STEM OPT is a post-completion extension.

How many days can I be unemployed during STEM OPT?

Maximum 60 days unemployed during STEM OPT (24-month extension period). Aggregate 90 days across the initial OPT + STEM OPT combined. Exceeding this ends your F-1 status. Report any employer change within 10 days.
