Borrower defense to repayment, might also be called a DTR:

If your school misled you or engaged in other misconduct in violation of certain state laws, you may be eligible for “borrower defense to loan repayment,” sometimes shortened to “borrower defense.” This is the discharge of some or all of your federal student loan debt.

You can find out more info about borrower defense to repayment on the Department of Education’s website.

It’s very easy to apply.  Download the pdf file, answer some questions, upload the pdf.  Because your claim is extremely time-sensitive, I highly recommend answering the questions in a cursory manner, and afterward, putting together the supporting documentation.

You don’t have a lot of time to get your claim in.  You do have time, after it’s been made.  The hands of the government do not move swiftly.
