For whatever cultural reasons Chinese abroad tend to stick with other Chinese.<p>Since there are many Chinese students in the US (and Canada, UK, etc.) they often don't really interact much outside their circle of Chinese friends.<p>Now, of course it's not easy to move to a different country with a different language and culture, but I think that the cultural aspect specific to Chinese plays a significant part. I think Indians are somewhat similar in maintaining a strong community among themselves when abroad.<p>In general, I would say that the best thing that can happen to you if you go to study abroad is to end up being alone. That really forces you to integrate with the local people, culture, and language, which I think is the whole point of going abroad.
