It uses the Internet and the World Wide Web to exchange information between NSF and its external community. Individuals applying for NSF Graduate Research Fellowships can use FastLane to create and submit the required forms and letters of reference. NSF no longer accepts paper submissions of any kind. The PIN will be required each time a PI wishes to use FastLane applications. Registration is required for others who will be working on a proposal.
