Deferred grad school acceptance for fellowship, can I apply for other programs?

[Dostoprimechatel'nosti]

Last spring, I received a grad school acceptance with a great funding package. I accepted the offer, but then received a Fulbright grant for this year. My grad program was happy to defer my acceptance for the year. Now that I have been working in my field internationally on my Fulbright grant, I have found 2 other grad programs in the same field that are a better fit for my academic and international career interests. Would it be wrong to apply to those 2 other grad programs and, if accepted, decide between the 3 programs in the spring? Is it frowned upon to not enroll in a grad program that granted a deferral? Thanks for the input and advice!

The program you've accepted is expecting you to come and will take into account this "filled" spot in their admissions decisions. It's not fair to them to hold this acceptance while applying to other places. That's my interpretation, at least. You can also contact the university directly.
