President Trump signed an executive order on Tuesday that directs the Treasury Department to issue formal guidance to financial institutions regarding the examination of customer citizenship status.

The order requires banks to more closely scrutinize the citizenship status of their customers as part of the administration's broader immigration enforcement efforts. Treasury will provide formal advisories to financial institutions outlining procedures and requirements for such examinations.

The executive action represents part of Trump's campaign pledge to increase enforcement against individuals living in the country without legal authorization. The order tasks federal agencies with developing guidelines for how banks should handle citizenship verification processes.

The timing coincides with the administration's absence from recent United Nations discussions on global migration policy. The State Department indicated opposition to international efforts that could facilitate migration to the United States.

Details about specific implementation timelines and the scope of banking institutions affected by the order have not yet been released by the Treasury Department.
