Setting Immigration policy though is a power the constitution strictly delegated to the federal goverment. So cities and states can't take this issue into their own hands .
The 10th amendment says : any power not delegated to the fedreal goverment by the constitution or not prohibited by the constitution can be used by the states or the people .
Immigration policy though is a power delegated to the fedreal government which means the states cannot take the issue in their own hands.
Yes, the constitution gives the federal government the sole authority to set immigration policy. And yet it is also a bedrock principle of constitutional law that the federal government may not commandeer state authorities by ordering them to enforce federal law. There is nothing unconstitutional about local government telling the Feds that they refuse to do their jobs for them.
I am sure that heavily involving federal law enforcement in the affairs of individual cities is something they would
love to see.
