I'm heading over to the USA in June to travel around for a month with some friends from Denver who are touring with their band.
What kind of pre-arranged permit/visa will be needed, if any? Someone told me you simply need to fill out a boarding card on the plane whilst someone else told me you need to pay for a visa a few weeks in advance. Which is the case?
Also, I am coming over on my own-I have heard that immigration pick out people on their own and question them excessively-is this true?
Many thanks!
