Maybe I'm naive about how many foreign pilots would be willing to work for a us regional, but I doubt there is enough qualified foreign pilots that would want to make a jump to a us regional to have much of an effect on the supply and demand of regional pilots here. My guess the pilots that would come would be trying to get a 1000 hours in a e 175 and then jumping to anther foreign carrier that pays better than the US.

With that being said, I'm not sure such a deal even fits in with our current work visa structure in the US. It also may open a whole political can of worms within the public eyes with our current immigration issues. Also, If a pilot's ultimate goal is becoming a permanent resident or citizen here in the US, a work visa isn't necessary a path to that in our convoluted immigration process.
