I'm not suggesting we deport all the current legal visa holders (expensive)
We've no need to. Illegals must be rounded up and deported (killed if they violently resist), but existing nonwhite legal ("legal") temporary workers can simply have their work leases expire, with notice that there will be no extensions, so they can find lodging in another country.
just cut off the issuance of new visas (cheap)
Exactly.
