If you have federal student loans, you might be eligible to get all or part of the interest that accumulates during your service term paid for you.
Forbearance means that you neither make payments nor pay interest on your loan(s) over a specified period. In other words, you will not have to make payments on your loan(s) while you serve. Then after you successfully complete service, the National Service Trust will pay the interest that gathered while you were a member.
Loans do not go into forbearance automatically. There is a forbearance process to follow; the earlier in your term, the better.
