Deferment:

You are responsible for paying the interest that
accrues on your unsubsidized Stafford Loans and
your Grad PLUS Loans during all periods of
deferment. On subsidized Federal Stafford Loans
the government pays the interest during deferment
periods.

The date on which you first received your oldest
outstanding student loan determines your
eligibility for deferments. For more information,
contact your lender/loan holder or use Mapping
