When is the deadline, and how do I request an extension?

Our deadline is typically in mid April; see For Applicants for details. We are sorry, but we may not grant extensions. Our submission deadline is firm so that we may complete the review process by our notification deadlines and in order to ensure that all applicants have received equal treatment. To ensure that you have time to address technical difficulties, please allow yourself time to plan for potential technical difficulties or any unforeseen delays.
