Assuming I attend college in CA as a non-resident, I only need to pay the out-of-state tuition once, right? and then next year I can qualify for in-state tuition since I will legally be a California resident?

If this is not true and I need to pay out-of-state tuition all 4 years, then that is absurd. this year, my whole family will be moving to california for good and this just so happens to be my first year in college. I should be considered a resident after a year.
