Interesting solution - I don't know how the visa system works but if these doctors decided to switch careers after they got here in order to provide better for themselves/their family is there anything stopping them? It still seems like it's misaligning the incentive structure to produce the desired results.
At the base of the issue is that being a doctor is a difficult, stressful job that requires high intelligence and sometimes even high physical dexterity. While it's nice to think that people would choose to do it because it's moral to take care of people, I don't think it's fair to expect that these people wouldn't want to be appropriately financially rewarded for their gifted skillset.
