No it is not discrimination against those countries. But, there are a few countries that are known to support cheating among students intending to attend US schools. This is not a new thing. Cheating can happen anywhere and there have been scandals in the US as well. A difference is that in the US students may cheat but the involved adults (parents, teachers, school administrators) are not all working together to help the cheating. Rather, when an adult gets wind of it they put a stop to it and usually penalize the student pretty significantly. And it would be unheard of to have a made up or forged transcript and grades and bogus letters containing lies about the applicant. That would not happen. But there are probably hundreds of students now enrolled in mediocre to poor US schools with students from certain countries where that type of corruption is supported. And some can’t speak English at all or barely. And they hang together with others who probably used similar bogus credentials to gain access. I don’t think this happens in better schools but I believe it is somewhat common in less strong (and lousy) schools. I think the US should stop accepting any students in situations where there is question about the student’s credentials. When countries are corrupt there is no accountability. This is institutionalized and country sanctioned cheating! Don’t want the cheaters bringing that mentality to our schools! But it is not an indictment against all students and it is not discrimination. But unless it is possible to verify credentials, students from countries that promote cheating should not be admitted to US schools.
