It's almost certainly not just US schools too. I remember in grad school that some of the students (at least one Chinese sticks out in my mind) were absolutely not fluent English speakers. It was definitely a requirement for the program, but they couldn't manage a coherent sentence, let alone paragraph. Sadly, Sweden is almost entirely group projects, so I think they just got carried through by colleagues despite not being qualified in the slightest. It was frustrating and sad. There were definitely some very smart Chinese people too who should have been there. But I feel bad for the people whose spot they took who might have actually been qualified.
