answer:It’s too hard to answer, with the information you have given. Every student has to choose the school that best serves his or her educational goals and temperament. Without know knowing what your friend plans to study it is difficult to know what school might be best for him or or. Also, without having intimate knowledge of the four schools in question and your friend, I think it would be very difficult for someone to answer questions regarding the relative benefits of one school over the other, in terms of on-campus jobs and graduate assistantships opportunities. And as to job prospects after MS? Obviously, just because one goes to school in Kansas or New York doesn’t mean that one is limited to the job prospects either of those areas. Choosing the right college or university is a big and important decision for anyone. Choosing a school when it involves moving to another country is an even bigger decision. I think this is all research your friend has to do. It is his life. He needs to steer his own ship.
