I'm not sure I get it, are you saying that wage alone should determine visa eligibility? I'm gonna guess that location is the primary reason here. Do you have any data, for example, on foreign workers that stay versus bail on rural/remote jobs in the long run? My rough guess is that there's more than just looking at the money. Maybe these doctors are picking these jobs as a gateway to later switch to a preferred location and aren't staying, so they are being more picky? (My comment is anecdotal and I have no basis just a hunch)
