The talk on FOM has only been in stopping people without jobs coming here but they could secure those jobs and still come here
My family are spread out all over the world - my own DP lived abroad and worked, my aunts uncles, siblings etc and DH family too. So I grew up in household always talking about who was living where and what job and sometimes how they didn't get the job, were not allowed to go back for work and so on. I have family on one side split as they cant all live in Oz. So all this is very normal to me.
A friend wanted to live and work in Canada, they could not just go they could not just find a job, and get it and go.
They had to go through a painstaking long process to get there, including, flying to canada to do a written test on the job he said he could do, like - brick laying! He failed the test - it cost over a grand, all told to get there etc. He had to do it all over again, BUT, the employer also had to prove to the government that he was not taking a single Canadians job. That the job had been advertised, and no one came forward, time limits and so on.
It was a GARGANTUAN process and there is no way they would have gone through it - had they not desperately wanted to live in Canada. Now they are there - because they had to work so hard and really want to live there - they appreciate it - respect it and love being there.
I would like to see similar here, I was to see British jobs prioritized for British workers first.
