What privilages does a vountry get if it becomes a member of NATO, except military one.?

Question

I mean does U.S.A become more tolerant about visas given to the citisens of these countries.

Answer 1

Membership in NATO  doesn't provide any visa privileges simply as a result of joining NATO, as the folks in Poland, the Czech Republic and other recent members have discovered. There is no connnection between membership in NATO and participation in the Visa Waiver Program. However, as the economies of those countries improves and the motivation to emigrate decreases, their chances of joining Visa Waiver will improve.

Answer 2

NATO is purely a military treaty or a system of collective defense. In theory it means that if a member state is threatened, it has the backing of all other member states.

All the privileges or benefits are defense related. It brings stability to the member states; they share R&D to some extent; there is a pool of military resources that can be used; they share intelligence; and if NATO is involved in a conflict (eg: Bosnia and Kosovo) members need to provide proportionally less assets.

It will only help your visa if you are directly related in NATO forces.
