More importantly, which school? If you are an undergrad, your residency might come down to where you parents live. If neither live in that state, the fact that you do may not mean a thing if you are not independent for college purposes. And colleges have an age 24 rule unless you are married, have a dependent, are a veteran of the armed forces or have a court ruling declaring you independent (usually for abuse/neglect/emancipation reasons). That is very difficult to get.
As you can see in the thread right near yours, others are seeking the same thing. Every year hordes of kids seek in state status for OOS publics and usually they don't get it because of the way the rules are stated and enforced. You can be a state resident for voting, driving,paying taxes. just about everything, but not for in state tuition rates at many schools. So you had better check the rules carefully. Your parents are out of the country, but where was their last legal residence in the US? The rules are often set up deliberately to keep undergrad from getting in state status for tuition while they are going to college.
