U.S. government regulations require international students on F or J visas to enroll in a “full course of study", and also limit the number of online credits that can be counted towards a full course of study. With the onset of the COVID-19 pandemic, the Department of Homeland Security issued COVID-19 guidance that allowed international students to exceed these online study limits. Fully online study was permitted for students who were present in the U.S. on March 9. 2020. Students who arrived later were required to have at least one in-person class in addition to any online classes.
