California is sympathetic to DACA students and is working on the issue at its public colleges and universities. I think most of it only applies to instate residents, so you need to check individually with those universities. Additionally, if you want to compete in California, ALL of your stats have to be exceptional. There is no way of getting around that. California has plenty of DACA students with exceptional stats so you have to be competitive and have ALL of the A-G coursework completed or near completion.
As for private colleges, in California, you need to call the individual financial aid offices at those schools. Each school is handling it in a different manner.
FWIW: California is a very expensive state. Even for in-state students, the costs of attending a UC has many families affected by the costs to attend. Every student wants to come to California, thinking of what is shown on TV/internet: that it is an easy transition and beachy weather. Try again. My dd went to Davis, in the middle of farmland. It is a college town. She had a dormmate (from OOS) who was walking around in a swimsuit, asking how to get to the beach. She asked my dd why people were laughing. My dd had to tell her that Davis didn’t have a beach. The nearest “beaches” were on the coast, a trainride away, and were not really swimmable.
