Dornslife to Viterbi Switch?

Was admitted to Dornslife, how would one go about to switching to Viterbi, if at all possible?

My son transferred from Dornsife to Viterbi after his first semester at USC. All students are allowed to take 4 courses in any college without getting permission (as long as there is availability in the class). So, my son took the three classes USC requires in order to be evaluated for CS; 2 CS and one math course. He then filled out the paperwork, they reviewed it and let him transfer. It’s not an automatic admit, however. USC states that it is competitive and they also review your entire transcript, test scores, etc. in addition to the three USC classes.
