Some of the student criticize their university if they are not happy with something, it is not right to criticize your university if things don't go your way. The more you criticize your university or college the more you criticize your self, because you will be the student of that university and you will be the product of that university. Instead of criticizing and complaining deal with it, and the problem is too big then try to discuss with the administration or the staff in international office at your university. If you are still not happy about the problem you have then write a letter to the higher authorities at your university and ask the international office to help you to submit it, or try to submit it in person by your self. Some of the universities are very big its hard to get access to the higher authorities but its possible. Complaining and criticizing will not solve anything instead it will make you more frustrated and it will drop your own image in many ways.
