Senate Bill No. 660, known as the Oklahoma Foreign Agents Registration Act, aims 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 file 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 maintenance, and the Attorney General's responsibilities in enforcing compliance, along with penalties for non-compliance.

The bill mandates that agents of foreign principals who have acted in this capacity since January 1, 2014, must file retroactive registration statements. It specifies exemptions for certain diplomatic officials and legal representatives and requires agents to disclose their status when engaging with government officials or transmitting informational materials. The Attorney General is tasked with maintaining public records of these registration statements and reporting on the act's administration. Penalties for willful violations include fines and imprisonment, and non-compliance is treated as a continuing offense. The act is scheduled to take effect on November 1, 2025.
