Senate Bill No. 660, known as the Oklahoma Foreign Agents Registration Act, seeks to improve public transparency regarding the activities of agents representing foreign principals from countries identified as a concern. The bill defines key terms such as "agent of a foreign principal," "country of particular concern," and "foreign political party," and requires these agents to register with the Attorney General. They must submit a detailed registration statement that includes their business activities, affiliations, and financial transactions, with updates required every six months. The legislation also outlines exemptions from registration, record-keeping responsibilities, and the enforcement role of the Attorney General, including penalties for non-compliance.

The bill mandates that agents of foreign principals who have acted in this capacity since January 1, 2014, file retroactive registration statements. It requires the disclosure of any informational materials sent on behalf of the foreign principal, which must include a clear statement of their origin. Penalties for willful violations include fines and imprisonment, and non-compliance is treated as a continuing offense. Certain individuals, such as accredited diplomatic officers, are exempt from registration. The Attorney General is tasked with maintaining public records of registration statements and reporting on the act's administration every six months, with the law set to take effect on November 1, 2025.
