I think Cary missed the real question with this one.
It takes only a few seconds on Google to find a multitude of links on the writer's putative topic.
This sounds like another version of, "I want to quite my soul-deadening job but don't know how." (And its corollary, "Am I wrong to want this?")
Why does the writer feel compelled to pull up stakes and move on to a new identity, in effect, every two or three years? That's an issue deserving of introspection, not the apparent (bordering on incredible) inability to find moving-to-France help on the web.
