Whenever in the judgment of the Attorney General any person is engaged in or about to engage in any acts which constitute or will constitute a violation of any provision of this subchapter, or regulations issued thereunder, or whenever any agent of a foreign principal fails to comply with any of the provisions of this subchapter or the regulations issued thereunder, or otherwise is in violation of the subchapter, the Attorney General may make application to the appropriate United States district court for an order enjoining such acts or enjoining such person from continuing to act as an agent of such foreign principal, or for an order requiring compliance with any appropriate provision of the subchapter or regulation thereunder. The district court shall have jurisdiction and authority to issue a temporary or permanent injunction, restraining order or such other order which it may deem proper.
If the Attorney General determines that a registration statement does not comply with the requirements of this subchapter or the regulations issued thereunder, he shall so notify the registrant in writing, specifying in what respects the statement is deficient. It shall be unlawful for any person to act as an agent of a foreign principal at any time ten days or more after receipt of such notification without filing an amended registration statement in full compliance with the requirements of this subchapter and the regulations issued thereunder.
It shall be unlawful for any agent of a foreign principal required to register under this subchapter to be a party to any contract, agreement, or understanding, either express or implied, with such foreign principal pursuant to which the amount or payment of the compensation, fee, or other remuneration of such agent is contingent in whole or in part upon the success of any political activities carried on by such agent.
