I would suggest taking a global perspective and thinking what should be good for the world and not only US. Think trade, cultural exchange, international collaboration in research (think of recent publications that often have hundreds of names on them, from many countries).

When you start thinking globally, term like 'foreign worker' would start sounding ridiculous to you. And protectionist policies probably would stop making any sense as well.

On the other hand, naturalization should take some time. Fast track citizenship doesn't make much sense, as it does take some time to get the culture of the place [e.g to serve public duties, like jury duty, etc].
