Of course visa tracking needs to be improved. More funding for that would be great. It is a separate question…
NO one said that a wall was the beginning and ending of immigation law enforcement.
Now…once you increase interior enforcement (need ICE for that…not getting rid of ICE) and deport visa overstays…they are not going to be able to reenter for many years, if ever. That’s where a wall comes in.
And no one is proposing a complete wall for every inch of the border.
An extended and improved wall…as one aspect of immigration law enforcement…is what is being proposed.
