Hi,

I'll be in US for the first time, flying into JFK, and then LAS, then LAX and then SFO. I'm not a very experienced traveller -- are there any different procedures in US than there are in Europe? Obviously, as a non-US citizen, I will probably have to go through a different check-up or something, but for those 4 particular airports, do you think there might be something that could confuse me? Idk, baggage claim, security, check-ins, etc...

Thanks for any little tip!
