But with this case, you have a large linguistic barrier that goes both ways. The experience is only partially simulated compared the article author's experience, because she did not have any linguistic barriers. I experienced the 1st generation chinese/russian linguistic barrier myself too. I think the big reason why is because there is an engineer shortage, or science grad student 'shortage', so many candidates are going to come from their social networks, which are probably mostly russian or chinese. They themselves don't feel comfortable with the external language and culture, so they associate with people they feel more comfortable speaking with and it self perpetuates. It only goes away when their children are born in the next generation, or they are isolated enough that they are forced to integrate.
