If you graduated high school in California after a sufficient amount of attendance, you can use the AB540 provisions to get in-state tuition and financial aid if, for some reason, they decide that you are not a California resident due to one term of out-of-state college attendance.

The web site focuses on DACA-type students, but US citizens and permanent residents are eligible and probably are most of the AB540 students. The provisions of AB540 and similar laws in some other states effectively mean that students who graduate high school in a state but whose parents move out-of-state can still be in-state for tuition purposes.
