Just to be clear, the prohibition on re-verification, in this context, is not a major departure from existing federal law:

You can re-verify employees whose work authorization you know is about to expire or be altered shortly, for example. You can set up automated reminders, esp. if you have a decent electronic system for maintaining these records, which you should. You can also set up audits in order to clearly limit them to appropriate employees and situations. There are several reasonable, legitimate exceptions: https://www.lawlogix.com/employers-p...e-i-9-squeeze/

This is not an unreasonable or suspicious law. It protects legitimate workers. Some people may be upset by the fact that it also protects "illegals", but almost all laws already do that.
