nepalibabu, most of the universities in the US provide scholarship. there are even more universities that offer scholarship, assistantship programs specially for masters degrees.

your question is really vague to answer in a single paragraph. but to cut it short,

the scholarship depends on major that you are going with, depending on the major they have different criterias, depending on your scores/ eligibility on what they are looking for on that particular criteria for that particular scholarship/ assistantship, they will decide how much/ what part/ what type of assistantship that you will be offered out of that particular scholarship program within that particular criteria.  :)

so, its complicated right?

to make it simple, you need to tell people what are you?  what is the major are you choosing?  kind of explanation! hows your educational background  etc...   dont you think so?
