Great question! Understanding the difference between OPT (Optional Practical Training) and CPT (Curricular Practical Training) is crucial for international students on an F-1 visa in the USA.

OPT (Optional Practical Training)

- What it is: OPT allows F-1 students to work in the USA for up to 12 months (24 months for certain STEM degrees) in a job related to their field of study.
- When: Most students use OPT after completing their degree (“post-completion OPT”), but it can also be used during studies (“pre-completion OPT”).
- Approval: Requires application and approval from USCIS (U.S. Citizenship and Immigration Services).
- Work hours: Full-time (post-completion) or part-time (pre-completion).
- Eligibility: Available after completing at least one academic year.
- STEM Extension: Students in STEM fields may apply for a 24-month OPT extension.

CPT (Curricular Practical Training)

- What it is: CPT allows F-1 students to participate in internships, cooperative education, or practicums that are integral to their curriculum.
- When: Can be used during studies only (not after graduation).
- Approval: Approved by the university’s Designated School Official (DSO), not USCIS.
- Work hours: Part-time (20 hours/week) during the semester or full-time during breaks.
- Eligibility: Must have completed at least one academic year (with some exceptions for graduate programs that require immediate CPT).
- Requirement: The job/internship must be a required part of your program or earn academic credit.

Important:
- If you do 12 months or more of full-time CPT, you become ineligible for OPT.
- Both CPT and OPT must be directly related to your major field of study.
