typically you don't get funded for MS at admission. Some unis might give you a tuition scholarship. You might find an assistantship once you're here.
If money is an issue I would recommend applying for cheaper schools like TAMU, or just working in India for a couple of years and saving up.
I remember SBI had some special education loan scheme for NIT IIT BITS graduates. Might want to check that out.
You have to show you have finances for a year to get an I-20 (you need it for the student visa).
