You can find out if you are eligible by logging in to studentloans.gov and selecting the link: Request a Direct PLUS Loan. After you fill in all requested information, your credit will be reviewed and you will be notified if you are approved or denied this loan. Generally, you are eligible if:
Your Direct PLUS Loan enters repayment once your loan is fully disbursed (paid out)
If you wish to you may contact your loan servicer to request a deferment while you or your child are enrolled at least half-time and for an additional six months after your child ceases to be enrolled at least half-time.
If your loan is deferred, interest will accrue on the loan during the deferment. You may choose to pay the accrued interest or allow the interest to capitalize when the deferment period ends. Your loan servicer will notify you when your first payment is due.
