I attended a rather prestigious Graduate School program in the Liberal Arts at a state school. Education specifically. Campus population in the tens of thousands.
In some classes, I actually felt like part of a minority. There were consistently large populations Asian nationals in the field. Many nationalities, mind you, such as South Korea, Taiwan, Thailand, and maybe one or two others. Teachers in their home country, they were attending to get the US Masters/PhD with every intention of returning home and getting a raise.
Yes, they did participate well in the learning environment, language issues aside, but more than one got homesick and would quit the program due to culture shock of living in the US for 2+ years. I can sympathize.
My takeaway was that the University was very happy to take the (presumably) higher tuition from foreign students primarily interested in the Degree for status advancement than turn them away. It could help keep a department going in a way, and, in turn, the University didn't worry that these graduates were going to stick around and try to get US jobs on those degrees. It kind of wasn't the bargain.
It is worth noting, I think, that most of the Asian national students in my program or field were in their 30s or 40s. They had life experience, families, professional careers...I guess the point of the reflection is the University got a good revenue stream and the Graduates got their Degree for status back home. Win-win? Ehhhh...
