UVA has a good mix of American-Asian Indians (fair amt in both engineering, business, and sciences), but I am not sure about the international Indians. We tend to have a lot of international asians concentrated in the graduate schools (prominently in the math, physics, engineering, med school departments). Honestly, I can't tell if you're an international indian unless you begin talking and I notice the accent. In terms of student life, I think that if you are alright with living and talking with students from different backgrounds, then you'd be swell anywhere. The faculty provides support when you want it and internationals are called upon to meetings to voice their opinion on how their life is like. We have indian movies in stock at the library

. You have students that also help you:
Indian Students @ UVa. It's a good community, and I think that you can make great friends if you allow the opportunity.
We do have a strong greek life, which is true for any top school in the south and the frats and sororities have amazing mansions designated to them, which means that if you want to join you have to be very committed to your brothers/sisters in terms of how seriously you take your membership (if approved). However, I don't see it as a culture that overwhelms the community. Sure we have over 40 frats & soror, but if you want to avoid them you can (since the houses for each are not as close to student housing despite some being on campus---more like on the other side of the road). People just have other things to concentrate on (like the 400 organizations we have on campus, research, volunteering...etc).
Virginia Tech is not seen so involved in greek life, but because it does have a lot of indian students, it might be an easier transition for someone coming from outside of country. I am not too knowledgeable about tech, but we are its rivals in sports. The only reason why I would say Vtech is more asian indian type is because Vtech's ISA
VT ISA | Home is geared to providing newly arrived indians from India. Whereas, UVA's ISA
Indian Student Association at The University of Virginia is pretty much a cultural expression club filled with asian americans. I think this is the best example I can provide to display the difference that may not be evident for people who actually live in India.
