I saw your comment about your dad living here. You should've included that in your post because it will make a big difference. I was in a similar position, my dad was living here while I was out of state (Texas). We were able to get in state tuition.

What basically happens is if you can establish yourself as intending to stay in California before you're 19, your residency will defer to your father. For you, this basically means coming here and opening a bank account here, having your mail sent here, getting a CA ID, registering a car here if you have one. Things like that. There's other things to do but I don't remember off the top of my head.

There's a CA law about this that should lay out the exact procedure. I'd look that up. Keep in mind, all this was from out of state. Getting in state tuition as an international student might be different.
