Unfortunately you won’t be exempted. My husband was raised in CA and went to a CA high school which is why he got the AB540 to help with costs, but he still had to wait a year after becoming a LPR in order to be seen as instate. I think what lindyk8 is getting at is that it is a lot harder to prove instate in your situation. The UCs could and would easily assume you moved to CA solely for school, which doesn’t get you CA residency in the way of instate tuition. In order to establish an actual CA residency, you have to prove that CA is more than a place for your education, you need to prove the intent of making it your home permanently basically.
With my husband, he lived in CA before becoming a LPR, attended high school here, started his family here, and as his wife, I’ve been a resident here my whole life. So ours is more than just for educational purposes.
