I'm a US citizen and I will be traveling to Argentina this winter. While I'm there, I'd like to make a short one-week trip into Brazil. I haven't picked the dates yet, so I don't have my travel ...
I am an Australian wanting to travel to Los Angeles for 3 months then south America for a couple of weeks before returning
If I leave to go to south America for say two weeks can I then return to America with a new tourist visa and a fresh 90 days?
