The part of these immigration bills that I hate most is the requirement for new forms of identification and surveillance of US citizens. I gather this is supported by nearly everyone in Congress. Orwellian surveillance is not controversial in the US, where "Land of the Free" has been replaced with "Let me see your papers."
When the US adopted a requirement for US citizens to prove their citizenship in order to get a job, I vowed I would never do so. I will never again be an employee in the US.
