I moved to France over 23 years ago and was lucky in that I had an easy introduction and no money problems.
But I had to learn the language and come to understand a different mode de vie.
I do have some regrets; such as not having London (museums and theatres) close by. But at least it is easy to return when ever I want to.
Surprised you would want to move to the US due to the expense of living there. Hope you do achieve your dreams.
Always wanted too for some reason, at this rate it'll be me retiring rather than moving out to live and work, it'll take a good 5 years (at least) to get my degree so i'll see what happens as the future approaches me
