Interesting, Freya.
It reminds me of something.
I and my colleagues from other western countries, had to have work visas to work in a south Asian country back in the nineties. Since the government never got round to making our visas long term, we had to cross a border into another country every month to renew our short term visas.
I was only about an hour's drive from a border but for some people it meant a longish flight, somewhere to stay for a day or two and another flight back to where they worked.
So, when people say asylum-seekers in Britain "aren't allowed to work", I just remember the visa requirements even for invited people in the south Asian country I worked in.
And I shrug and don't find the no work until approved policy, or whatever it's called, at all strange.
