@Northernmom61 didn’t quite give the full picture. It doesn’t matter if your parents claim you on taxes or not for FAFSA. For FAFSA you are a dependent until you are 24, married, or military, OR in foster care (and a couple other rare situations.) Just because your parents don’t claim you on taxes does not make your independent for financial aid purposes for gov’t or university aid.
@nogoofy your statements are too goofy. If you are already a CA resident then you should already be getting instate tuition and fees. Can you please clarify why you are asking about instate when you are already a resident?
If you marry, you can file your FAFSA as independent. How are you supporting yourself, is it independent of your parents? I am not sure if the UCs will give you extra aid if you are using your parents for living expenses.Sometimes if you enter under one status they have expectations that would continue, as far as university funds go. I’m not sure how it would work out. Presumably your ‘spouse’ would not be supporting himself and paying his own tuition. You would have to report your joint incomes for FAFSA. I don’t know how the money he gets from his parents would be reported. Are you or the other student going to consult an attorney as there could be Visa issues?
