I've lived for long periods and traveled extensively in several parts of US, Canada, bits of Europe, HK, etc.
You don't want to move to the US, unless you really, really , really know for sure what you're getting into.
It's somewhat different between states, but boils down to:
Nothing like being asked by a stranger reading USA Today in the restaurant (or workplace, whatever) "we should nuke all those country terrorists, what do YOU think?". The old "are you with us or against us?" treatment.
Ditto HK: a few interesting lifestyle possibilities at first, esp. as a single, but then sailing off Stanley Beach for a year?
Living elsewhere is fun at first, but. No place like home.
Even Nicole came back...
