Getting married to a Polish Citizen in the UK [371]
1. Does she have a US driver's license?
2. Does she have any kind of US ID?
Because that's all you need when you cross the border.
Probably the best for you is go to Las Vegas and get married. License costs $55.00, takes 20 minutes, you can have a cheap wedding with no waiting period and once you're married take her with you to Canada. You show the border patrol your wedding license, that she's your wife, who doesn't have any other form of ID with her and you'll be fine.
Best if you cross in Sault St. Marie in Michigan or North Dakota because they don't check the ID's so much. Don't go through New York. They are more thorough there.
I also got several other ideas. Contact me via e-mail.
