“Employers currently have the ability to find out who is a citizen and who is not.”
Nonsense. Anybody can buy a fake ID with your name and can provide your SS#. Employers can’t weed out identity theft even if they wanted to.
The E-Verify system is up and running and is available to anyone that chooses to use it. It is being done in my state of Indiana and it is successful.
It matches numbers from the social security system with other data, and it works. Period.
