Hi Raman, take your GRE. However, you already hold a Masters, admission will be tricky. Since, you are there in US already you can gain information more easily. Check the websites for program specific information and admission requirements. If you are still an international applicant you must follow norms set for internationals otherwise you will apply through the same process and pay the same fee as domestic applicants.
