How old do you have to be to travel to USA?

I am 15 years old, and i already have a USA visa. I would like to visit the states for a week. Would i be allowed to go alone?

Only if you have an adult waiting for you here.You are a minor and can't travel alone.You need to be 18 to rent a room.

you can be any age, but to be able to rent a room and a car and stuff like that you need to have someone there to to that kinda stuff for you or you need to be over 18 but you can go on a air plane and all that by you self, good luck! :D -AB

Theoretically, you could go to the United States, but you'd have to have an adult to rent a hotel room for you. Unless you want to spend your trip homeless.
