I think they should all be sent to Ukraine and made to spend at least 2 years with the Ukrainian army before they are considered for processing. (If they survive)
They should be made to prove themselves worthy of living in the UK first be prepared to die protecting it and it's way of life it should also come with conditions.
in order to integrate and live in the Uk they must convert to Church of England and live as a native British citizen would with British morals eat a full English breakfast as well as a lovely roast pork Sunday lunch every week drink English beer adopt a football team dress as a British person would abandon their old way of life and speak English.
(For English substitute Scots, Welsh, N.Irish if living there)
