F2 Visa... Need Help....?

Well, you need to have the university include you on the I-20 student form, and they need to put you in the SEVIS database. Since you can't work in the US, your wife needs to show that she has the ability to provide for you while in the US. And, of course, you'll need a marriage certificate to prove your relationship. Where will you live, what will you do are questions you should think about.
