Here is an example of the documentation that is needed:
CAREFULLY READ THESE INSTRUCTIONS BEFORE UPLOADING DOCUMENTATION OF YOUR FINAL STUDENT AID INDEX (SAI) AMOUNT
Do NOT submit an estimated SAI.
It usually takes 1-3 business days after your FAFSA is successfully submitted for the Deparment of Education to process it and generate your FAFSA Submission Summary (FSS). You will find the final SAI on the FSS.
