On October 31, the New York Times highlighted China's difficulties in keeping residents from emigrating to other developed nations. While China's economy has experienced robust economic growth in recent years, more and more Chinese continue to leave the nation in search of a new life.  The lack of religious freedom and the lure of a more liberated social and economic environment has driven an increasingly high number of Chinese out of the country. In 2010, 508,000 Chinese departed for one of the 34 developed countries that compose the Organization for Economic Cooperation and Development (OECD). The U.S. welcomed 87,000 permanent residents in 2011, up from 70,000 in 2010.  But this feeling of uncertainty and unrest is not a one-way street.  The lethargic recoveries hampering the economies in the West has driven Chinese students back home in droves. In 2011, the number of students returning to China was up 40% from the previous year. Even still, it appears China is experiencing a sort of "brain drain." The United States' investment-based green card program allows foreigners to obtain a green card if they invest over $500,000 into American businesses. Chinese citizens obtained well over 2,000 of these specialized permits, more than double the investment-based green cards of all other nationalities combined.
