i am doing MCA. After completing my MCA I am interested to pursue MS computer science in USA what talents should I improve to pursue MSCS.

There is no such course as MSc.computer Science. you have to do all specialized courses like, networking, animation, data mining. like that. As you have already done a masters, you can do one year research degree. If you are looking for a job and going to US, better thing of doing this course in UK
