As stated by several posters, the UC’s and Cal States offer no need based financial aid to OOS students except for any Federal aid a student is eligible.
UC Regents, Chancellor and Dean’s scholarships are competitive merit based aid that OOS students are eligible but the amounts vary between campuses from $2000/year to $13000/year which are small amounts in comparison to the $67K/ year price tag.
The Cal states have even more limited merit based scholarships than the UC’s and usually require students to apply after they are admitted.
