I am Chinese, and I made a promise to myself and to all my families and friends that I will never give up my Chinese citizenship or try to be an American citizen, but I have to go to that country across Pacific ocean to achieve my final goal, i.e. to be a real scientist and a writer. Really, the United States is not perfect. American thinking way has created a lot trouble in humans, but it is also American thinking way that created modern civilization, and developed human intelligence on the maximum level, at least by so far. Actually, there are a lot things we have to admit. Going to there to experience life means knowing about a new thinking way and broadening view.
