graduate admissions - Applying for MS in USA after completing 3 years degree in India

I have completed my Bachelor of Computer Applications (BCA) from India. The minimum requirement for admission into the MS in Computer Science program requires a 4 year college degree. My BCA degree was a 3 year degree and I am planning on pursuing a 1 year Post Graduate Diploma in Computer Applications (PGDCA) from Indira Gandhi National Open University (IGNOU) and would like to find out if these total 4 years satisfy as minimum requirements for admission consideration.
