If a bitcoin exchange site takes USD bank wires, what information do I need from the exchange site? And, do I need to do anything from the exchange site's end?

For example, I have a EU bank. So I convert the EU into USD in my EU bank, and how do I proceed from there?

What exhange sites can i register as a corporate entiry to trade bc?

Im trying to purchase bitcoin outside the U.S. Is there an exchange service that sells to anyone regardless of citizenship?
