So I'm an American exchange student over here for the next 6 months with a short-term student visa. I'm in London studying. I was wondering how difficult it is to travel to other surround EU countries and how difficult it will be to get back into England. I wanted to go visit a friend in Barcelona next month but am afraid to leave the country because of how tough customs can be here!
If this helps, I have something on my visa that says "MULT VISITS". Does this mean I can go to other countries and when coming back to England, not get hasseled by customs again?
