I am a college student and worried because I have never been out of the country by myself before. I will be traveling from Chicago O’Hare to London Heathrow and back to O’Hare from Heathrow. I have two two-hour layovers, on the way there at Stockholm and on the way back at Copenhagen.
Am I going to need a visa at any of these airports?
If so, how do I get one?
