Decision deadline?

I received an acceptance letter from OU. I’m trying to find the deadline of when I have to make my decision. (It wasn’t stated anywhere on the letter) Other colleges deadline seem to be on the May 1 but I have no idea for OU. Can any tell me when I have to make my decision?

All American colleges have a May 1st deadline as mandated by [National Association for College Admission Counselling’s Good Practice Guidelines.](http://www.nacacnet.org/about/Governance/Policies/Documents/SPGP_9_2013.pdf) The University of Oklahoma is considered a member college of NACAC and thus adheres to the deadline even if it does put some incentives in place for those who enroll earlier (ie better first year housing options).

@whenhen wat about the transfer deadline because am plannin on sending my final transcript after this spring semester, hopefully i get accepted
