When on Curricular Practical Training (CPT), how are part-time and full-time defined by USCIS?
USCIS defines part-time as working 20 hours or less per week. Part-time CPT does not affect your eligibility for OPT, nor is there any limit on the number of semesters that you may engage in part-time CPT before graduating. Full-time CPT is defined as working 21 hours or more per week. If you accumulate 365 days or more of full-time CPT authorization, you will not be eligible for Optional Practical Training (OPT).
