I can't speak for other schools, but I have been accepted to UNECOM. I had hoped to defer a year in order to move my whole family up there together. I was told that they only grant deferrals in cases of dire emergency. In my situation, my husband has a job commitment until the fall of next year, so it will require that I live away during the week and commute home weekends (about a 3 hour drive). The admissions director said that while my situation was unfortunate it did not qualify for deferrment. Each school probably has their own guidelines.
