Many of you are aware that engineering transfer applicants are not required to submit letters of recommendation. Our application (the Common App + USC Supplement) provides us with the information we need to make an admission decision.

You can mail follow-up application materials, such as a letter of recommendation, and all other types of correspondence to:USC Office of Admission
