> Whereas the US, for all of its flailing around politically, is perceived by many people in many countries as a good place to move. The lower language barrier is a massive help. Thanks to British colonizing half the world, there are over a billion people who speak and understand English. Hollywood (and now, TV shows) help too. American culture is already familiar to most people across the world. You're less likely to get a culture shock moving from India to USA than from India to China.
