This will be interesting as it seems to follow the Japanese and Korean models of growing talent abroad and returning home.
Unfortunately, the home they return to is not an ethnocentric utopia like Japan/Korea. It's an ethnocentric, smog/corruption ridden dystopia that just so happens to now be the world's economic superpower.
With America's global standing in the crapper thanks to decades of anti-immigration fearmongering policies lead by the GOP, it'll be interesting to see for how much longer it can stand as the de-facto place for global STEM talent.
