I do not think it is true that NYU kicked you out just because of excessive absence. You just missed too many classes and did not take your advisor's advice. You also missed exams, so you got F. It is very easy to transfer to other colleges in US. Why didn't you do it? I have my doubt that you are merely flunked, but got excuse. I have seen many different kind of excuses for missing classes and exams. If I were you, I'll transfer to other college to get a bachelor degree. A college dropout is regarded as a failure in China. Think about it and wish you the best!
