Do immigrants do this often? I mean sell their houses, cars and other belongings before moving abroad? It's a sincere question from someone who also considered emigrating for work at some point. I could never imagine getting rid of all my stuff before I actually sit down in the office with my new bosses and co-workers for a couple of months and have a taste of what it is like. I won't be buying any house or a car in the new place right away anyway. I could just rent both before I decide I want to stay there for good. Or am I talking from some sort of a privileged position of a person who has some savings to deal with situations like this ... or maybe I'm too conservative and that's why I never left?
