@goldencub is absolutely correct; as an OOS student, it will be very difficult to transfer into a UC program that is impacted. It has been done, but given that you are trying to get into the most popular UC’s, your chances are low for a number of reasons.
The UC’s are public schools for the benefit of instate residents. For transfers; priority goes to instate CC residents. Last priority are OOS university students.
As per @Gumbymom, You will pay $55,000 per year without any money from the state of California. The state of California does not fund OOS students, so you will pay full fees; any scholarships you have at your present school, will probably not go with you unless these are federal dollars or private scholarships that will fund UC schools. You also will not gain instate residency to reduce these costs. Living with relatives will not make you instate.
You need 60 transferable semester units that the UC’s will accept. The UC’s are picky about what courses will transfer in, and which they won’t accept, so if you don’t have, what they consider equivalent GE courses, you will be rejected.
