As an aside, I’ve seen this happen elsewhere as well. Classic play for wage theft. When I was working as a bartender in London to make ends meet, I had a coworker from Mexico on an expired visa. Great guy and the most hardworking. Well won’t you guess it, guy got picked up by immigration authority on payday.
It seems many newcommers are not aware of this blatant fact. It outstands me when they think being bourgeoisie friendly is tolerated in this network.
