I have to disagree with justshutupandtakeit. If amnesty were given to the estimated 12 million illegal immigrants residing in the United States at the present time, the real number of new immigrants that could lay claim to American citizenship would be something like 30 to 40 million. We have to remember the extended families of the illegals in the U.S. would legally be given the fast track to citizenship, if amnesty to illegals were granted. If I'm not mistaken, there are between 300 and 350 million people legally living in the United States. Amnesty would change the make-up of American society to drastic proportions, since 30 million new immigrants is nearly one-tenth of our current population. Hysteria might be an understatement concerning what the proposed amnesty will mean to our country. Remember, if the danger is real, it is NOT paranoia.
Though I have said nothing advocating amnesty it would not necessitate the problems you speak of. There is no requirement to extend it beyond the individual to which it is granted.
