The UC’s offer little merit aid for OOS applicants. Regents is available for the top 1-1.5% of applicants but the most money you will receive would be around $10K from Riverside. The other campuses listed give less. There are other scholarships listed on each schools website that may be possible but you need to do some research. None of these are automatic and many not only involve competitive stats but leadership and volunteering. Have you looked at this link for automatic scholarships?
