More than half a million federal student loan borrowers remain in a backlog of applications to access an affordable repayment plan, according to a new court filing.

The Trump administration reported on Monday that 576,609 borrowers’ requests for an income-driven repayment plan were still pending as of the end of February.

Many student loan borrowers rely on IDR plans to be able to afford their monthly bills. The plans limit monthly payments to a share of discretionary income and cancel any remaining debt after a certain period, typically 20 or 25 years.

The U.S. Department of Education also did not forgive any student loan borrowers’ debts under an IDR plan during the month of February, Trump officials reported.

Another 88,170 federal student loan borrowers are waiting for an answer on their Public Service Loan Forgiveness buyback application, the court filing showed.
