Dear All About MS in CS:
We are not quite sure if your have the requisite academic qualifications for an MS in computer science. The minimum entry requirement is 4 years of college/university education in programs that lead to degree qualification. As a result, unless your Bachelor's degree is of 4-year duration - such as in engineering - you are expected to have completed a Master's degree from India. Diplomas are typically not considered relevant to fulfilling the academic requirements.
Admission requirements vary somewhat across colleges. You should research the colleges of interest for college-specific requirements. You can find the
List of Computer Science Colleges in the US in the
iMahal Education Channel. You would be required to take the GRE (Graduate Record Exam), a standardized entrance exam. You can find
Information on Entrance Exams in the
iMahal Education Channel. The
iMahal Education Channel also offers the
iMahal College Finder which finds colleges that best match your performance and needs.
Having identified target colleges, the process for applying is no different from that in India: Submit an application form and other required documents, and wait for an answer. Most colleges offer application forms and information on the admission process on their websites.
