OPT = Optional Practical Training

CPT = Curricular Practical Training

Both are F1 student related and STEM related in regulation of how many hours a F1 student may work

CPT may be part-time (20 hours per week or less) or full-time (more than 20 hours per week). If you accumulate 12 months of full-time CPT authorization, you lose your eligibility for Optional Practical Training (OPT), another type of employment authorization for F-1 students
