I am in eastern Europe and our foreign students are all from Asia. Huge mental shortcut.
All my groupmates were and most of my doctoral committee are from Russia/Ukraine (the remaining member will be from China) but only one has non-North American (USSR) PhD
Stop being so pedantic about this and take it from an American perspective. The amount of grad students in my school's department from Europe is very low, and the amount of American grad students is also very low. That's what he's trying to get at here.
