I don;t think top 5 Universities have lots of Nepalis ( if not any).
w/o scholarship i dont think its possible to study Graduate/ post graduate... yearly cost can run from 35-50,000
I have heard that after six months, we can maintain our study cost even if we do not get any scholarship
who ever said this ask him how?

Besides, you have to do research on your, contact which ever univ you want join, ask them what kind of program they have.
