emjas,
As an international student, you will have a difficult time visiting both colleges before the May 1 deadline. Have you tried to contact the college international student offices (
International Services Office for the UR ISO) or the admission depts to see if they have students who are willing to correpsond with you?
Perhaps you can check out some of the campus clubs that host activities you are interested in and contact them. Ds#2 did check out the clubs and even contacted students whose contact info was posted, just to get some idea of activity levels.
Mind you, after all that's said and done, reality may till not fit the image you have formed from all the investigations. Just what you find and run with it.
As to graduate schools, you have 3-4 years before you need to worry about it. First you have to settle on a major. Then find yourself a mentor/advisor in your major to determine the best program for your field. It is the contacts you make during grad school that will be most helpful in finding work after graduate school. I do not know what country you are coming from and do not know if you would be considering academic positions after graduation. The overall reputation of a school may carry more weight with the general public but in academia, the strength of a departmental program is more significant. The example that comes to mind would be writing - U of Iowa has a great reputation as one of the best but the university itself would not be ranked as high as, say, Harvard in the public's mind. You may want to pose the question of where the foreign alums end up after graduation to the international student officers. My bias would be UR for undergrad and then look for the best program for grad.
Good luck with your decision.
