keep PART 4—NOTIFICATION OF FOREIGN OFFICIAL STATUS
Requires foreign diplomatic and consular missions to notify the State Department's Office of Protocol upon arrival, changes, and termination of all foreign government employees and their dependents, including U.S. citizens and permanent residents employed by such missions, using standardized forms.
This regulation implements core sovereign functions: tracking foreign diplomatic personnel is essential for national security, enforcing immunities appropriately, and fulfilling U.S. obligations under the Vienna Conventions. The modest administrative burden falls primarily on foreign governments, not American citizens or businesses, and serves a legitimate, constitutionally federal interest that cannot be achieved through decentralized alternatives.
