We've brought over the years more than 30 developers from Eastern Europe some 8 years ago here in Southern California. Nobody wanted to stay for more than 3-6 months even though they got better pay here and no expenses to worry about - company lunches and dinners, nice company cars, nice spacious company houses, etc. On the contrary, when they go back to Western and Central Europe to work for clients, they didn't want to leave!
