To re-enter the U.S. during your OPT or STEM OPT period, you must carry: your passport, a valid F-1 visa, your I-20 with a travel signature less than 6 months old, your EAD (or STEM receipt plus expired EAD during the 180-day extension), and a job offer or employment verification letter. DHS guidance and university best practices confirm the 6-month signature validity for students on OPT. Traveling while your initial OPT application is pending is risky; it is safest to wait until you have the EAD and proof of employment.
Common Traps to Avoid: Compliance Mistakes
- Starting work early—before receiving your EAD and before the authorized start date.
- Missing filing windows—USCIS must receive your I-765 within the strict post-completion timeline; STEM applications must be filed before your current EAD expires.
- Forgetting STEM reporting—The 6-month validations and 12/24-month self-evaluations are mandatory.
- Exceeding unemployment limits—90 days for standard OPT, 150 days total for OPT plus STEM, including most time spent abroad.
- Using 12+ months of full-time CPT—This eliminates post-completion OPT eligibility at that degree level.
- Non-compliant STEM arrangements—Working for a non-E-Verify employer, without pay, without bona fide supervision, or failing to update the I-983 for material changes.
Quick Compliance Checklist for OPT Success
- Maintain valid F-1 status; request an OPT-recommended I-20 from your DSO.
- File Form I-765 within the required window and consider premium processing if timing is critical.
- Wait for the physical EAD; begin work only on or after the start date.
- Work ≥20 hours/week in a job directly related to your major; maintain a memo explaining this relationship with reference to your coursework.
- Report all changes within 10 days: address, employment starts/stops, and employer details. On STEM, complete 6-month validations and I-983 evaluations.
- Track your unemployment days meticulously; do not exceed the limit.
- Keep a complete compliance file (I-20s, I-983s, EADs, I-9 proof, offers, pay stubs, W-2s).
