As someone with a bit of higher education experience. There was a large amount of Chinese students paying cash to do their Ph.d's in the US. Probably 50% of the student body in some schools. A large portion of that 50% went immediately back to China after obtaining their degrees.

How many of them had children on US soil before returning?

Of the ones I knew, zero. They got their degree, put all of their stuff in the apartment dumpster, a lot of it brand new, and left. Can't speak for others.
