This government WILL make it impossible for the average American to distinguish these people from real citizens - take EBT cards for example replacing food stamps to make the stigma go away and make it harder for the average Joe to spot a leech at WalMart. Or, Section 8 housing where the government moves lowlifes into your neighborhood instead of putting them where they belong - in public housing.
The point I am making is that normal suppositions about government procedure do not consider collusion with WH goals in this deluded case. We won't be able to tell them apart from Adam, by normal documentation - mark my words, [GAFFER, June 17, 2012].
Unless the Govt does away with the SS# requirement, they will either need a WP or some other paperwork. If the govt tries to give them an SS card like ours, that will take time and there will be exposure.
Then IF they do manage to sneak it in and make them ‘invisible’ you’ll just see lots of real American ‘hispanics’ unable to find work because many businesses just won’t hire anyone who looks Mexican.
Unintended consequences.
