Proposing an amendment to the Constitution of the United States to prohibit any person who has citizenship or nationality of, or otherwise owes allegiance to, a country other than the United States from serving as a Representative or Senator in Congress, a Judge of the Supreme Court or any inferior court, an Ambassador, public Minister or Consul, or any other officer of the United States which requires the advice and consent of the Senate, or the President or Vice President unless the person formally and permanently relinquishes such citizenship, nationality, or allegiance.

On June 3, 2026, Representative Nancy Mace (R-SC) introduced H.J.Res. 194, a joint resolution proposing a constitutional amendment to bar individuals holding foreign citizenship or allegiance from serving as Members of Congress, federal judges, ambassadors, or the President/Vice President unless they formally and permanently renounce such status. The bill was referred to the House Committee on the Judiciary, the first step in a long legislative process. Constitutional amendments require a two-thirds supermajority in both chambers and ratification by three-fourths of state legislatures, a process that historically takes years and has a low success rate. This bill is at the earliest procedural stage with no committee hearings, markup, or floor votes scheduled. It authorizes no spending and creates no regulatory or procurement mechanisms. No publicly traded companies are directly affected by this legislation, as it targets individual eligibility for federal office rather than corporate activity, contracts, or market conditions. The bill's impact on markets is negligible at this stage.
