UCI: changing major from CSE to CS as an incoming transfer.

I got accepted to UCI as CSE major but I want to switch to CS. What steps should I take to change my major? I sent a request through UCI MyAdmissionPortal and was declined because CS was not accepting new major changes. I tried again on StudentAccess but it said “Incoming students must visit academic counselor of the new major…” Does this mean I have to wait until orientation to change my major? What if they tell me I can only try to change my major after the first quarter? If that is the case, what classes I should take in the Fall? CSE clasess or CS classes? Should I try to sent a request again on MyAdmissionPortal in a few weeks, after everyone SIRed and the people on the waitlist are taken care of?

Plan your schedule as if you will stay in the CSE major, since the 90 (quarter) units or less restriction makes it unlikely to change to CS (though there should be significant overlap between the two, so you could make progress in both for the first few quarters).
