How should I let Nelnet know that I want to apply and request a TPD discharge?
You do that by phone or by e-mail.
What does Nelnet notify me of after I am declared disabled?
Nelnet will notify you that you will be subject to a three-year posdischarge monitoring period that begins on the date the discharge is approved, and that your obligation to repay your loans or complete your TEACH Grant service obligation will be reinstated if you don't meet certain requirements at any time during this monitoring period.
