You won’t get instate tuition in California. You will be OOS for all four years.
The problem is that you will be coming to California for educational purposes. It’s almost impossible to be classified as a resident, given how much documentation is required by the residency committees.
If you aren’t moving to California with parents, then it will be assumed that you are coming for your education. Coming to California for educational purposes means automatic full fees. If your HS transcripts are from out of state, the committees scrutinize everything.
You have to be self sufficient for two years prior to the residency determination date and you cannot receive financial help from anyone. This is if you can find a full time job that will support your living expenses including expensive housing. Rents and transportation costs, in Southern California, are ridiculous!
You have to show proof of work with tax receipts, budgets, rent receipts at market rates, that match your expenses.
The California universities have thousands of students trying to get instate residency. Where they get you is the location of your parents.
