harikancha, Tucson is a very safe place to live. I lived there for 11 years and never had any problems. Of course, if you go around looking for trouble than it may not be safe. But then that is true for any place. University of Arizona is a good school. Live near campus and find work on campus. It gets hot in the summer but for me it was not a big deal. UA has a diverse student body. I think there are more Indian students than Mexicans. If you are into sports, UA have one of the top college basketball team in the country.You will enjoy cheering for the Cats. Some NBA players that played for UA are Sean Elliott, Steve Kerr, Mike Bibby, Gilbert Arenas, Richard Jefferson, Jason Terry to name a few. And if you are also into studies, UA has the number one Astronomy department in the country. MIS dept. is in the top five. Good engineering college and so on. Tucson is a beautiful city surounded by mountains. You can go to Old Tucson and check out how and where old western movies were made. I hope this helps you harikancha in making your decision. Good luck.
