Curricular Practical Training (CPT) allows international students on F-1 visas to work in paid internships or training related to their major while studying in the U.S. Students must secure a job offer before applying for CPT, which must be an integral part of their curriculum, and can start working part-time or full-time depending on their academic level. Various programs, including work-study options, facilitate immediate employment opportunities for students, enhancing their English skills and professional experience.
