Students returning from a leave of absence and who wish to register for classes must first contact their major advisor. The  Student's advisor will contact the Viterbi Admission and Student Affairs Office to remove their LOA hold.  Students who are away for one semester or less will retain their priority for registration and register on their regular appointment time.  Students who are gone for more than one semester may register after all current students have registered for classes (late November in fall and late April in spring).  Students may contact the Office of Registrar at register@usc.edu and request an appointment time to register.
