> What I've seen among H1-Bs is a far higher percentage of people who basically hate their job, but do it because it allowed them to come to the US and afford a comfortable lifestyle for their families. I don't blame them for that, but I also don't think that it makes them particularly good developers.
Most people from China, India, etc who immigrate to the U.S., Canada, and Australia/NZ are, in my observational experience, primarily focused on whatever aids the immigration process from an early age, often prompted by their parents. Their secondary focus is the backup plan of rising in the ranks of business, government, or academia in their home country. There is a significant minority of people whose primary focus is on the hierarchy at home, and choosing immigration as a secondary concern happens later on in life, often after marriage, perhaps to someone of the first group. For both groups of people, though, an interest in something geeky like technology, programming, gaming, or whatever comes a distant third. People in China who develop such consuming interests outside of work or forgo higher status jobs to do more interesting work will almost certainly miss out on some crucial step in the arduous immigration process. And of course you won't see many Chinese who totally forgo saving for a car, apartment, spouse, and child to spend all of their time on a geeky interest because their parents simply wouldn't allow it in the one-child culture here.
