hey tamkhan, check out pyriots posts over the last two pages answering dantheman's question, she does a good job summerizing all the pros of NYU.
I cancelled my interview at BU once i got into NYU. While BU seems to be going in the wrong direction, NYU is headed in the right direction. New facilities, faculty, new dean ( the consensus on these forums is that he is wonderful), no shortage of patients, best technology. The school is going to be among the top dental school in a few years, if it keeps doing what it has been doing. The price tag of both schools is similar, so why spend more money on a school with more problems. Plus you will have the opportunity to network due to larger class size, alumni network, and all the dentists in the city.
I know the whole UAE thing influences your decision heavily, but with NYU opening a campus in the same country as well, getting a job should not be a problem. Any american degree, especially one from a university known worldwide will help you to get a job.
just my 2 cents, im sure there are more reasons to attend.
