Here's the email they just sent out if it helps. It specifically references those who will receive need but may not have yet as part of the reason for pushing the deadline back.
We have been receiving a number of requests from admitted applicants for extensions of our first seat deposit deadline. We appreciate that choosing which law school you will attend is an important decision and that you are considering a number of factors very carefully. We also understand that many admitted applicants are still waiting to receive need-based financial aid decisions.
Dean Lawrence and the entire GW Law family are committed to doing whatever we can to help you as you make your decision. Toward that end, we are extending our first seat deposit deadline from April 15th to May 1st. I am pleased to get this word out to you -- sooner rather than later -- in an effort to lessen any anxiety and pressure you may be starting to feel.
So -- if you wish to reserve your seat in our fall 2010 entering class, please complete the Intent Form we included in your acceptance package and return that completed form to us, along with your first seat deposit in the amount of $500.00, no later than May 1, 2010 (must be postmarked by May 1st). Please note that seat deposits must be in the form of a check or money order, made payable to "The George Washington University," and that all seat deposits are nonrefundable. Please send your form and seat deposit to:
GW Law - Admissions
700 20th Street, NW
Washington, DC 20052
As always, please let me know if you have questions or if I may be of assistance as you prepare to begin your legal studies -- I hope at GW Law!
