Mandatory E-Verify will be used for more than illegals if it is allowed, government will be able to unperson targeted groups and keep them from being able to live.

Taxing all foreign remittances that don’t provide proof of citizenship/legal presence at 50% is a good one.
Putting bounties on reporting illegals is another good one.
