<p>A lot depends on how competitive you are and how much “room” there is in the particular major/school you’re applying for. My D was originally a sociology major when she applied to USC, after she was admitted, she switched to undecided, then narrative studies in CLAS. Thereafter, she applied 3 times to School of Cinematic Arts & was accepted and happily enrolled now there. She was waitlisted twice for majors in that school (it had no openings for new students) while accepted for the other major.</p>
<p>There really aren’t any guarantees that you will get admitted into the school if you’re not admitted when you enter that USC, but you could try to get a minor in it if not admitted to major into it. Try speaking with the advisor for the school of communications</p>
