American immigration law are rooted in racism. The last American law that was named correctly was called “Chinese Exclusion Act” where a white majority managed to pass a law to kick out legal residents of the country and forcibly taking over their property. Of course, it is the same country that until recently considered blacks as animals.
But when American leaders pompously talk about “illegal immigration” you need to realise that they harass legal immigrants even more and subject them to more inhumane restrictions.
