And about Parent PLUS borrower deferment?
parents who received a Direct PLUS Loan to help pay their child's education and whose child is enrolled at least half-time at an eligible college or career school, may qualify for this deferment.
What could happen to my requested deferment if I stop paying my student loan?
if you stop paying your loan before you've been notified that your request for deferment has been granted then your deferment will not be approved and your loan will become delinquent and you may go into default.
