No because in the EU, we had equivalent training standards, recognised across the EU, also, we dropped the English language requirements, sp my DD was working in the NHS, she even went to a training event about the pros and cons of foreign workers in the trust.. upshot is we need them but the trust also has to make provision to supervise in many cases.

Germany does something similar, giving a work visa for those waiting for asylum claims to be processed.
