There has long been an immigration program for foreign doctors to gain the right to live and work in the US in exchange for first living in a rural/poor part of the US where most doctors do not want to live.
If have a nursing degree it's easy to immigrate to USA, in fact you will be coming in with a green card unlike tech worker. So to your point, US does prioritize nurses over others. Doctors are different and it's incredibly difficult for a doctor with a foreign degree to practice in US. I know this for a fact since I come a place where almost every other house has a nurse working in Europe/US
