Puerto Rico Higher Education Disaster Relief Act This bill amends the Higher Education Act of 1965 to waive the 90-10 rule through FY2020 for proprietary (i.e., for-profit) institutions of higher education impacted by Hurricane Irma or Maria. Under the 90-10 rule, such institutions must derive at least 10% of their revenue from nonfederal sources or risk becoming ineligible for federal financial aid.
