Asian parents who immigrated find it very difficult, as a rule, to let their children go to college far away from them. They fear the unknown, they want to visit you to be sure you safe, happy, well fed, etc. You need to contact CMU and ask if they have some Asian students like yourself, not international students, whose children are attending CMU and can help them see that there is a family at CMU which will take care of you. Best if the students you talk to have parents who speak the same language as you. CMU Admissions and International Student offices are very familiar with these kinds of cultural issues that come between the university and the parents’ fears.
