The "New Hampshire Higher Education Security Act" aims to prohibit nationals of the People's Republic of China (PRC) from attending state institutions of higher education in New Hampshire. The bill defines "PRC national" as any citizen or agent of the PRC who is not a U.S. citizen, including those with ties to the PRC government. It mandates that higher education institutions deny admission to PRC nationals and refrain from partnerships with PRC-affiliated entities. Institutions must obtain notarized affidavits from all applicants and current students confirming they are not PRC nationals, which must be submitted to the Department of Education within five business days. The act also introduces penalties for violations, including fines for institutions and potential criminal charges for individuals identified as PRC nationals.

Additionally, the bill requires the University System of New Hampshire (USNH) and the Community College System of New Hampshire (CCSNH) to separate from enrollment and employment of PRC citizens within 90 days of enactment. It prohibits these institutions from enrolling or employing PRC nationals or their agents and mandates the same notarized affidavit process. The financial implications are significant, with USNH estimating a potential annual revenue loss of over $2 million and CCSNH facing compliance costs of $100,000 to $500,000 per year. The bill modifies existing criminal penalties, which may affect the judicial and correctional systems. Overall, the act is designed to enhance national security while imposing substantial administrative and financial burdens on the state's higher education systems.
