The F-1 visa allows foreign students to temporarily live and study in the U.S. while their academic program is ongoing. This document outlines four steps for F-1 students to follow when traveling outside of the U.S.: check that their passport is valid for at least six months beyond their end date of study, ensure travel timing does not extend beyond the expiration of the F-1 visa, bring a valid signed I-20 form and F-1 visa as proof of student status, and limit trips to five months or less to avoid needing a new visa application.
