Most graduate students in the U.S., period, have financial aid. Don't talk nonsense.
Oh, if only it were true. Students in the humanities & arts rarely get support. It's mostly in science & tech (follow the money all the way back to federal, military, and corporate grants for research.)
Anyway, the point wasn't whether or not graduate students got support. The point was that as engineering and/or science/tech students, Indian graduate students obtained support and didn't need to take out loans, rely on their governments, etc. Of course they are relying on *our* government (through the grant schemes mentioned above) and are relying on *our* state and federal tax dollars to subsidize their graduate educations.
