More than 20 percent of your healthcare force are immigrants. This is because most people who were born in the US cannot afford US based medical training. It is way cheaper to graduate elsewhere and then only pay for an equivalence in the US. And then get recruited.
Still you have clear shortage in staff.
The solution is to address the high expenses and access to higher education. If you stop hiring foreigners, you will be dying like bunch of flies and face more loss in workforce. More loss in healthcare sector. You have to first open access to medical school and compete by merits not financial abilities. Your very lives for now rely on immigrants' influx.
Just my two cents as someone who gets jobs offers from North America and other western countries, and worked in the context as an immigrant.
