The Military Installation and Critical Infrastructure Protection Act of 2025 is designed to bolster the security of agricultural land and critical infrastructure in Oklahoma by prohibiting foreign principals from foreign adversary countries from owning or controlling such properties. The bill outlines definitions for key terms such as "agricultural land," "critical infrastructure," and "foreign adversary," and establishes a framework for the divestiture of agricultural land owned by these foreign entities, mandating that they must divest within 180 days of the act's effective date. It also requires registration with the Oklahoma Department of Agriculture, Food, and Forestry, invalidates any conflicting contracts, and empowers the Attorney General to enforce these regulations through district court actions.

In addition to the ownership restrictions, the act prohibits foreign principals from purchasing or controlling property within ten miles of military bases and includes provisions for whistleblower rewards for reporting violations. It sets new regulations for companies accessing critical infrastructure, requiring them to file a certification form, pay a fee, and conduct background checks on employees, while also barring foreign nationals from foreign adversaries from accessing such infrastructure. Furthermore, the bill mandates that all software used in state infrastructure must not include products from federally banned corporations or foreign adversaries, allowing for their removal and replacement without additional permits. The Attorney General is tasked with overseeing compliance and reporting to relevant authorities, with the act set to take effect on November 1, 2025.
