If you're looking to relocate in the U.S. maybe try Hawaii. It's the. Most culturally diverse and if you ever wanted to go to Japan or Australia, it would be easier.
Hawaii has its own issues, though. My impression is that it's not the paradise it's portrayed to be.
Washington state or Oregon are most probably where I would go at some point. My company has an office in Portland, and one of my friends wants to move to Seattle. My boss has been suggesting for some time that Portland would be a good fit for me. I have doubts; it's a weird, intolerant city. I'm liberal, but I don't want to be surrounded by hippies who don't believe in fluoridating their water.
