A U.S. citizen is not an authorized representative of the United States unless specifically appointed by law, statute, or official delegation. Citizenship alone does not confer agency or authority to act on behalf of the federal government. In fact, the U.S. citizen is typically the regulated party—subject to federal jurisdiction, not acting for it. Authorized representatives must be lawfully delegated, such as officers, attorneys, or fiduciaries acting under express authority. This distinction is critical in legal, commercial, and equity contexts.
