Optional Practical Training (OPT) is the most critical post-graduation pathway for international students in the US on an F-1 visa. Used correctly, it provides up to 36 months of work authorization — and serves as the primary bridge to H-1B sponsorship. Used incorrectly, a single paperwork error can end your US work authorization permanently.
What Is OPT?
OPT is temporary employment authorization that allows F-1 students to work in the US in a job directly related to their field of study. There are two phases:
- Pre-completion OPT: Available while still enrolled. Part-time (under 20 hrs/week) during the academic year; full-time during summer. Rarely used because it consumes your 12-month allotment.
- Post-completion OPT: Begins after graduation. Full-time. This is what most students use. Duration: 12 months.
OPT Application Timeline
USCIS processing times for OPT EADs have historically been 3–5 months — making early application essential. The rules are strict:
- You may apply up to 90 days before your program end date
- Your application must be submitted to USCIS no later than 60 days after your program end date
- Your OPT start date cannot be more than 60 days after your graduation
Recommended timeline: Apply 90 days before graduation. USCIS issues the EAD with a start date you request, but does not accelerate processing. If your EAD isn't in hand by your requested start date, you cannot work until it arrives.
How to Apply for OPT
- Request a new I-20 with OPT recommendation from your Designated School Official (DSO). Do this at least 2 weeks before filing.
- Complete Form I-765 (Application for Employment Authorization) online or on paper
- Pay the filing fee: $520
- Submit: Form I-765, I-20 with OPT recommendation, copy of all previous I-20s, passport copies, visa copy, previous EADs (if any), two passport photos
- Track your case at uscis.gov. Do NOT travel internationally while your EAD is pending unless absolutely necessary.
The 90-Day Unemployment Rule
You may be unemployed for a maximum of 90 days total during your 12-month OPT period (60 days during STEM OPT extension, which counts separately). Exceeding this limit violates F-1 status. Your DSO is required to report unemployment to SEVIS. Remote work, freelancing, and self-employment count as employment only if properly documented — check with your DSO.
STEM OPT Extension: 24 Additional Months
If your degree is in a STEM field (see the full DHS STEM Designated Degree Program List), you can apply for a 24-month extension, for a total of 36 months of OPT.
STEM OPT Eligibility Requirements
- Your degree must be on the DHS STEM list (covers most computer science, engineering, mathematics, and natural science degrees)
- You must be employed (or have a job offer) from an E-Verify registered employer
- Your employer must sign a Form I-983 (Training Plan), outlining learning objectives and compensation
- Your salary must be comparable to US workers in the same role and location — the I-983 is auditable
STEM OPT Application Timeline
Apply up to 90 days before your current OPT expires. You have a 60-day grace period after the initial 12-month OPT expires to apply for the STEM extension; you can continue working during this period if your application was timely filed. Processing time: approximately 3–4 months.
Reporting Requirements During STEM OPT
STEM OPT has ongoing reporting obligations that don't exist for regular OPT:
- Validate SEVIS record with your DSO every 6 months
- Report changes in employer, job title, or work location within 10 days
- If you lose your job, you have 60 days to find new employment or change status
After OPT: Your Options
| Option | Timeline | Notes |
|---|---|---|
| H-1B sponsorship | Lottery in March; starts Oct 1 | Main path for most STEM workers |
| O-1A (extraordinary ability) | No lottery; apply anytime | High threshold but no annual cap |
| EB-1/EB-2 NIW green card | Concurrent with OPT if self-petition | Long processing; start early |
| Return to school (another degree) | Resets OPT eligibility | Not usable for same degree level at same school |
| Change to another status | Before OPT expires | L-1, O-1, TN (Canadians/Mexicans), J-1 |
Bottom Line
OPT and STEM OPT together give STEM graduates up to 3 years to land an H-1B or transition to another long-term status. The biggest risks are (1) applying too late and missing your graduation window, and (2) accumulating unemployment days carelessly. Start your application 90 days before graduation, maintain meticulous records, and coordinate with your DSO at every step. See our full US visa guide for H-1B and green card pathways after OPT.
