Banning legal & illegal migration for 5yrs

how will at risk jobs be filled if we cannot retain UK skilled people? we also have a skills shortage in many areas because of industry and manufacturing companies closing and those skills being lost.

Naive at best. How do you stop illegal migration? And we depend on legal migrants in nhs, care etc. Would that also apply to universities who rely on foreign students for income. It's another xenophobic rant.
