Hello Shashank,
Scholarships for MS in US universities is a challenging task. There are many conditions to fulfil. There are many nuances to this and if you miss out on any one it becomes most difficult to recover. I would therefore sincerely advise you to approach specialist agency dealing in sending students abroad particularly to US for desired results.

Now it depends on you, what do you want to do?
Best of Luck!
