Since graphics isn't such a popular major, I couldn't really recommend any universities in the US that are good in that field. There are plenty of universities that are great for business (undergraduate). The top ones from USNews.com are Wharton (good luck), MIT (good luck again), UC Berkeley, and University of Michigan–Ann Arbor. These are all pretty good and well known schools.
Another aspect you should consider is cost. Many universities in the US are heck of expensive, especially private ones (like MIT, Stanford, Harvard, etc.) so it's really a downer to factor those in. Public universities are usually cheaper for in state residents, but since you're international, it can be as expensive as a private university. I would suggest applying for any sort of international student scholarship you can find.

This might be a good source for US schools by major, or in general. They do a good job ranking universities overall or by whatever.
Majors and stuff isn't something to be worried about. Each school has a different system of how you can acquire your major with different requirements. It's basically a list of required courses which you have to pass in and a certain number of credit hours you must complete.
Jam it back in, in the dark.
