Have you ever moved to another country (as an adult)?

What was re-locating to another country like? How did you enjoy the life of an expat? Did you have a job in that country? How often did you feel the desire to return home (and did you do so)?

I’m just wondering if any of you have this experience. I know most of us here are in the U.S., but even if you temporarily lived in another country, I’d be interested to hear about it.
