Well, if you received a financial aid award, it said this:
"All awards are considered to be provisional and subject to change until all required documentation is received and reviewed by our office. Please submit your 2005 federal income tax forms (and all schedules), W-2s and those of your spouse and your parents by May 15. It is your responsibility to see that all documents are received and your application is complete. Delays can result in removal or reduction of your institutional award."
I forgot all about it until about two weeks ago. I was a little nervous about it being late, but since I didn't get an email, I guess they've got everything they need.
