Counter arguement: you need to do your own research/planning/applications and so on. There won't always be an easy "all inclusive" path. But opportunities are there for those who are looking for them.

That being said, it would massively help to speak at least one other language fluently.

You're also correct that it's not easy from a resource perspective. But if people from much poorer countries can make it work, than so can people in the US.

This person is unfortunately correct. One of the most educated and skilled employees within my group at NOAA was rejected from a job in France. Apparently, the board in charge of that scientific organization rejected her because they didn't want to hire an American :/

yeah that stuff is about grabbing PhD's with labs that have or could possibly win nobels and such or just is doing big things in technology. Bad for the us but not useful for people generally working in stem.
