<p>I'm kind of scared because I had my USC interview before I had sent in my form 1 part of the application. So basically I didn't have my USC student ID # yet. All i did was call and ask for an appointment, and they set me up with one. But they just sent me a letter confirming that they received my form 1 and asking if I want an interview. Does this mean that they have me under 2 different files? Should I call them and tell them I already had an interview?</p>
