Did you use applytexas? You should be considered as a Texas resident since you went to high school (Is it for 3 years?, then that might be the case) If you have, you're supposed to fill out the Residency Affidavit for UNT (saying that you will eventually try to get permanent residency).
Here are more information from their website:

I'm not sure, but you might qualify for Financial Aid under TASFA:
