The states have never delegated to the feds, expressly via the Constitution, the specific power to regulate immigration imo. So the State Department of the corrupt Obama Administration actually has no constitutional authority to tell any state how to deal with immigrants imo.
And the reason that the lawless Obama administration gets away with making policy for immigrants is because USA parents for many generations have not been making sure that that their children are being taught about the federal governments constitutionally limited powers as the Founding States had intended for those powers to be understood.
I agree !
