Once you have confirmed the actual deadline date, begin the application process as early as possible. Some organizations require application materials, such as reference letters, that take time to prepare. Each organization also has its own schedule for reviewing and funding applications, and you may be required to apply many months before the funds are available. A postmark deadline means application materials may be mailed as late as the specified deadline, as long as you can provide legal proof of mailing. A receipt deadline means that your materials must be received by the organization no later than the date specified.
Some proposals require delivery to a specific room other than an agency's central mail room.
Double-check the appropriate mailing address before delivering. Enrolled graduate students should look at the Graduate Student Support for Continuing Students brochure.
