You could be eligible for a deferment.
Are you unemployed? Do you qualify for Economic Hardship? Are you a student with at least a half time status? See the section on deferments

You could be eligible for forbearance.
Are you not eligible for a deferment but are still unable to make payments on your Federal Perkins Loan? See the section on forbearance

Your loan could be cancelled.
Do you work in a field full time that would allow your loan to be forgiven instead of having to make payments? Some areas include correction officer or law enforcement, certified nursing assistant, nurse or medical technician, teacher or teacher’s aide. See the section on loan forgiveness for more detail.

Have you considered consolidation?

Consolidation allows you to simplify the repayment process by combining your education loans into one loan. You will only make one payment, the interest rate may be lower, and the payment amount may be lower.
