“Cassa ‘just an increase in one area and a fall in another’
What on earth does that mean.”
The same as I surmised. The number of entrants to the UK will not change (apart from the growth which would occur with or without Brexit). The only difference will be that the foreign passport holders who previously went through the “EU” channel will, post Brexit, go through the “All foreigners” channel. So, far fewer staff needed in the “EU” channel (only UK passport holders will use it) and more needed in the “Foreigners” channel (which would deal with both non-EU and remaining EU people).
“I note the leave voters have chipped in with opinions and zero facts. As per.”
I don’t see any “facts” in your posts.
“‘I don’t know why you ask how Schengen will be effected‘
I asked merely to point out the OP’s basic flaw. I knew it was unanswerable.”
It’s not unanswerable. The answer, as I pointed out, is “not at all”. What you mean is that the question is actually irrelevant.
