probably problematic but a stereotype that I've developed after a few years of working in occupational health is that recent immigrants will almost always have negative drug tests, all vaccinations up to date, and exhaustive, meticulously organized documentation of any question you could think to ask
not because they're inherently more conscientious or whatever, more because there's a brutal survivorship bias for an immigrant to get to where they're working anywhere above-board enough to use an occupational health clinic
but after a while you do start thinking "oh, this guy has a heavy accent and presented a non-citizen ID? he's going to be no trouble at all"
