The three categories of OPT
International students in the United States can utilize OPT at different stages of their academic journey:
1. Pre-completion OPT
Participated in while the student is actively enrolled in their degree program. Students can work up to 20 hours per week while school is in session, or full-time during annual vacation periods. Any time used during pre-completion is deducted from the 12-month post-completion allowance.
2. Post-completion OPT
The most common pathway, applied for in the final semester prior to graduation. It provides up to 12 months of full-time legal work authorization starting after graduation.
3. STEM OPT extension (24 months)
Graduates who completed a qualifying degree in a designated STEM field (Science, Technology, Engineering, or Mathematics) and work for an employer enrolled in the federal E-Verify program can apply for an additional 24-month extension, totaling 36 months of legal work permission in the US.
Comparison: OPT vs. CPT
Students planning to study abroad in the United States frequently evaluate both practical training frameworks:
| Feature | OPT (Optional Practical Training) | CPT (Curricular Practical Training) |
|---|---|---|
| Authorization Phase | Usually completed after graduation (post-completion) | Completed before graduation while actively enrolled |
| Curricular Requirement | Not required to earn course credits | Must be an integral part of the academic curriculum |
| Approving Authority | Approved by USCIS (requires Form I-765 & EAD card) | Authorized directly by the university DSO on Form I-20 |
| Total Duration | 12 months (plus 24 months for STEM degrees) | Tied to academic course requirements (semester-based) |
| Employer Flexibility | Can change employers related to major field | Tied to a specific pre-approved employer on Form I-20 |
Step-by-step application process for OPT
- Request DSO recommendation: Contact your university Designated School Official (DSO) to endorse your Form I-20 for OPT in the SEVIS system.
- Submit Form I-765: File your Application for Employment Authorization with USCIS within the statutory filing window (90 days before to 60 days after degree completion).
- Receive EAD Card: Once USCIS approves the petition, an Employment Authorization Document (EAD card) is mailed displaying your official start and end work dates.
