For me to hire you, I am required to check that you have two of scores of acceptable documents that show that you have the right to work here. You need not prove citizenship, but that is one option. Another option is to show a work permit. Your tax id (i.e. social security number/card) + a state issued picture id like a driver's license will work in combination.
To verify that you haven't given me forged documents, I can contact the federal system establish by Senate bill 1685.
These are the existing ways. These aren't "to be" created by some new plan; these are already in place nationally.
"The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized."
National ID cards won't be far behind.
For me to hire you now, you have to check SS #'s. If that were being done now, there wouldn't be any illegals. If "acceptable documents" couldn't be forged on Pico & Union Blvds. on any given day, there wouldn't be any illegals. If the Feds were enforcing compliance now, there would be no illegals.
These systems are supposedly in place now & they are being subverted, ignored & unenforced. How is a guest worker program going to magically clear all this up?
