I think it is more about leaving their comfort zones. One might have to move out of their towns / states to access resources that the US has to offer. Dozens of US states offers so much support to their students studying STEM. You can defer education loan payments. There is so much federal aid. There are dirt cheap colleges if you want to get vocational education and start working quickly. But all of these are not available in one city. They are spread across the nation.

Globalization is a two way street. If you want the best of what the world has to offer, the best of what the world has to offer will arrive at your doorstep. That includes human resources.
