The Secretary establishes new regulations on the Public Service Loan Forgiveness (PSLF) program in the William D. Ford Federal Direct Loan (Direct Loan) program under 34 CFR 685.219 by adding or clarifying provisions to exclude employers that engage in specific enumerated illegal activities such that they have a substantial illegal purpose, including defining obligations and processes tied to making such a determination of an employer, clarifying that borrowers will receive full credit for work performed, until the effective date of the Secretary's determination that an employer is no longer a qualifying employer under the rule; and establishing methods for an employer to regain eligibility following a determination of ineligibility by the Secretary. These regulations ensure that taxpayer dollars are not misused by preventing PSLF benefits from going to individuals employed by organizations that have a substantial illegal purpose. The revisions strengthen accountability, enhance program integrity, and protect hardworking taxpayers from shouldering the cost of improper subsidies granted to employees of organizations that undermine national security and American values through criminal activity.
