Curricular Practical Training
Curricular Practical Training (CPT) is a form of temporary employment authorization available to non-immigrant foreign students in the United States who hold F-1 student status. It allows an eligible student to take part in employment, an internship, cooperative education, work-study, or another required practicum that is directly related to the student’s major field of study and is an integral part of the school’s established curriculum.
