Going to other state(s) after graduating as a specialist

In the process of picking schools. I don't want to practice in the state of the school I'll probably be attending and I want to hopefully specialize as an ortho. So I was wondering if specialists need to take new licensure exams (depending on what that state wants) like general dentists do? Or are they automatically approved by every single state?
