The 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. Students can apply for pre-completion OPT during their studies or post-completion OPT within 60 days of graduating. The application process involves getting OPT recommended in SEVIS, applying to USCIS, and receiving an Employment Authorization Document to begin approved employment. Travel while on OPT requires additional documentation and adherence to unemployment limits.
