First , you need to get a US passport . Bring this with you and get a photocopy as well just of the pages with your picture and identification . Second , as US citizen you get 90 days in the Schengen zone , which includes quite a few European countries . These countries are basically border less in the sense you won ' t have a border crossing to go through . There may be a passport check occasionally . Third , countries outside the schengen zone have varying lengths of time you can stay , generally it ' s 90 days though . When you cross between schengen and nonschengen countries , they will check and stamp your passport . That ' s it ! <| sep |> It ' s over . I had to pay $ 348 <| sep |> Best part about this is imagining the ' players ' list . Everyone on earth has a role to fill ! And we get to pick the words we use for them too . PUP
