Have to agree with the above comment. I am from the UK and I was unable to get to the campus prior to submitting my application. Then by chance I was in Boston a couple of weeks after the deadline so I called the admissions team and explained my situation. They were kind enough to let me visit and interview even though they would have been well within their rights to say no. I am not suggesting that everyone leave it late like I did, I don’t think the adcom would be happy with that, but I genuinely felt like they cared about all their applicants.
