This document provides information about Optional Practical Training (OPT) for F-1 students. OPT allows students to gain temporary work authorization directly related to their field of study for up to 12 months. To be eligible, students must have been enrolled full-time for one academic year and apply during a 150-day window before or after completing their degree program. The application process involves filing Form I-765 with U.S. Citizenship and Immigration Services. If approved, students receive an Employment Authorization Document and must report any changes to their employer or address. Travel outside the U.S. is permitted but may require additional documentation like an employer letter.
