I’m not sure what your goal is. Your tuition cost isn’t going to go down a dime when you marry an international student who is also not a resident of California. Sorry…but you will still be OOS.
Being independent for financial aid purposes probably isn’t going to be a huge edge either. You will still be OOS, and the vast bulk of need based aid in CA public universities is given to instate residents via the Calgrant.
Get married if you want to…but don’t do it for financial aid gain…because there likely won’t be much, if any gain. Yes, you will be an independent student for financial aid IF you support yourselves. But that will not give you instate status easily in CA.
Please clarify…have you already done a term of college in CA?
