Note that India requires prospective citizens to live in the country for 12 years before applying for naturalization, and China doesn't allow non-ethnic Chinese immigration at all (only ~1500 naturalized citizens/10,000 permanent residents in the whole country of over a billion people). Something to keep in mind when people from those countries complain about the American immigration system (doesn't apply to the Singaporean author of this article, but does apply to some of the other commenters).
