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 adversary countries—namely China, Russia, Iran, and North Korea—from owning or controlling such properties. The bill outlines definitions for key terms like "agricultural land," "critical infrastructure," and "foreign adversary," and establishes a framework for the sale, transfer, or divestiture of agricultural land owned by these foreign entities. It mandates that any foreign principal must divest their ownership within 180 days of the act's effective date and register with the Oklahoma Department of Agriculture, Food, and Forestry. The Attorney General is granted authority to take legal action against non-compliant entities and oversee the judicial foreclosure of properties in violation of the act.

Additionally, the bill prohibits foreign adversaries from purchasing or controlling real property within ten miles of military bases, with similar divestiture requirements. It introduces a whistleblower provision that rewards individuals who report violations leading to divestiture, offering 30% of the proceeds from the sale of non-compliant properties. The act also includes stipulations regarding the use of software in state infrastructure, banning any software produced by federally banned corporations or foreign adversaries. The provisions of this act are set to take effect on November 1, 2025, and it includes measures for the removal and replacement of prohibited software without the need for additional permits, provided proper notification is given.
