I know a person that was married after the initial green card they were divorced and everyone was happy. I don't know if they really care about being a citizen to much extra work involved. Citizenship would be needed if they were looking to bring family members back from china. I think they are more interested in being able to go back to china and come back to America. China is not some third world country their infrastructure is way better than here, I think they like it here because they can make a lot of money and they don't pay taxes. A few of the woman I've met planned on working here and going back to china to be with family and live the good life with what they made here. The woman I am talking about are in their 50s. Every person is different who really knows what is their motive, I do know it is a different culture and a different thought process. Overall the Chinese people are good people and thank god we have AMPs (life is good)
