If I marry a Polish girl will she become a citizen of the US?
Not immediately. In order to marry a foreigner and bring them
back to the states you have to apply for a visa for them. Fill out
a ton of paperwork and then pay all the fees. If you are already in
Poland, just go to the consulate and they can give you all you
need, or if in the military go to the personnel office they can
provide a lot of help.
