Mobile Phone use in the
US is EXPENSIVE. Don't pay the rip off charges over there, get a MAXROAM
sim before you go and get a US and Irish number in one. Call home for
the price of a local call from your mobile!
I've seen a few people on this site saying they've been over to the U.S. with the 90-day tourist visa and got a job; according to them they just told the employer that they were waiting for a social security number. Do you actually need a J-1 visa and SSN to get a job over there?
I'd appreciate any help clearing up the issue, cheers!
