Sure! I've visited about 8 different business schools in the US and Canada (I live and work in SouthAm), I really do believe it's important to know where you are applying, we will be spending two years there after all... but I don't think it is going be that relevant in the application, it is more of a personal choice I guess. If you live in NYC and haven't visited, then I'd think it could mean trouble xD
When you visit campus, you also meet several international applicants... I even stumbled upon some people from my undergrad program in 3 visits, so I think most of us, even internationals, are doing it.
