No matter what society we live in, we have to be actively involved in it. Even if you want to go back to China someday. The main thing is that you've got to know what's going on around you, get people know you, and have your voice heard. That way you feel connected to the society, and not isolated and marginalized. And more importantly, it means you are successful and as good as natives, even though you are from a different country for a long time. In that sense, you are more successful than most natives. Be open and let them know you. Also this will provide many more opportunities for your career. Be ambitious and achieve the American dream.
