A family I know wants to tour USC in early November. Are people allowed to walk around campus at the moment?
The Admissions Office is currently closed for tours according the Undergraduate Admissions website. As most students are not on-campus for the Fall semester, it’s likely not allowed (or highly unadvised) to visit campus. USC does have a virtual tour, however, which can be accessed via the Admissions website (as well as virtual events etc.)
