Immigration and customs are federal issues, not state issues, no matter how you slice it.
The problem isn't that there exists an organization to enforce, but the entirety of its approach ("find people to kick out / take to concentration camps"). Within the framework we have today, something like a non-citizen being convicted of a crime (handled by local/state) being handed off to ice to deport to the appropriate country of their residence? Sure.
But also borders are pretty stupid if a lot of the other stupid stuff around it goes away too.
