The last NYT article details how far US colleges will bend over to get full tuition paying Chinese students, who it turns out, aren’t even qualified to do the work. While many Chinese students are legitimate (understand college level english, haven’t doctored/forged transcripts, test scores, etc…) many are not, and it seems the US colleges only find this out after they have begun their studies here.
Another point is that this only seems to be done for the Chinese students- Korean, Indian , Taiwanese (all of which send almost as many students to the US) get no such treatment, at least at the same scale.
