Full-time enrollment is required for visiting international students who wish to obtain a UC Berkeley Summer Sessions I-20 (F-1). Full-time enrollment must be maintained during the entire period noted on the I-20. Dropping below full-time or withdrawing without approval from ISS may result in a violation of your immigration status.
You can find an overview of the full-time requirements per session on our visa website.
Contact visiting-intl@berkeley.edu if you face unexpected, extreme circumstances and are considering dropping below full-time only after you arrive. I-20s will not be issued to students enrolled less than full-time. Waitlisted courses do not count toward full-time enrollment.
