Department of Homeland Security is requiring federal contractors to use E-Verify, the agency cannot mandate its use by the states.
E-verify seems to be gaining traction is some states.
Will the law pass Congress this year, depends on how much time and money the special interest groups and big business spend.
My (and it is only a guess) that it will not pass, they will debate, put it off, and do nothing, at least until after the November elections. That will not leave time to pass it this year.
