How hard was it to get a deferred admission?
For my situation, not hard. I asked this question during my interview, and was told that they offer few deferments based on the reason why. For my situation, I am required to complete training for the Army first, which would interfere with my start date in August 2021, so they allowed me to defer to the August 2022 start date (Pretty sure its unlawful to terminate enrollment or employment status if military service is required of an individual, but do not quote me on that).
However, the amount of time that this process has taken has been awhile. You first have to fill out a form and explain why you need the deferment. It then goes to a committee, then to the dean, both of whom have to approve it.
My admissions counselor has told me that it has been approved on both ends, but I am still awaiting the official documentation (this has been going on for about a month and a half now).
Depending on your reasoning why you need is probably the biggest factor that they take in to account. Definitely get on it sooner rather than later, because like I said, it has been quite a drawn out process. Another unfortunate part is that I can't live in the campus apartment until I actually get enrolled in classes there, so I need to find a place to live in the general area for about a year. (RIP lol)
