Becoming an Air Traffic Controller?

I have been interested in Aviation my whole life. I wanted to be a pilot for so long, the only problem is I cant pay for the flight cost for training. I've been looking into ATC. I am going to attend the University at Buffalo for Computer Engineering this fall. If I do decide I want to become an Air Traffic Controller, should I transfer out of Buffalo after my freshman year and go to an ATC School? Or should I get my 4 year BS Degree first and then pursue ATC? Do I have to have a degree related to ATC to become a controller.
