While amnesty advocates and civil liberties zealots in the U.S. decry "police state" tactics against illegal aliens, Mexico fiercely maintains laws against illegal border crossings; "verification visits" to enforce visa conditions; requirements that foreigners produce proof of legal status on demand; and enforcement and cooperation between and among immigration officials and law enforcement authorities at all levels in Mexico. Native-born Mexicans are also empowered to make citizens arrests of illegal aliens and turn them in to authorities.
Mexico's National Catalog of Foreigners tracks all outside tourists and foreign nationals. A National Population Registry tracks and verifies the identity of every member of the population, who must carry a citizens identity card. Visitors who do not possess proper documents and identification are subject to arrest at any time. And for those seeking permanent residency or naturalization, Mexico requires that they must not be economic burdens on society and must have clean criminal histories. Those seeking to obtain Mexican citizenship must show a birth certificate, provide a bank statement proving economic independence, pass an exam and prove they can provide their own health care.
Applicants are assessed based on a point system using factors such as level of education, employment experience, and scientific and technological knowledge. Property acquisition and ownership by foreigners is still severely restricted. Mexican corporations are banned from hiring illegal aliens.
Exit question: If such self-interested "nativism" is right and good for the protection and survival of Mexico, why not for the United States?
