Noone would come to the US. US regional pilots are the lowest paid in the world. Foreigners would simply earn more staying in their own counties than working in the USA for 22k per year. Why would they come here to starve? If the regionals paid them better, then I could see people coming here. But moving to another country while earning a very low wage is not an attractive move to these foreign professionals. Don't expect professional pilots to flock to the US like central american migrant workers do.
