Nancy Mace Wants a “Natural-Born” Test for Congress, Reopening a Fight Over Who Counts as Fully American

American citizenship has long carried a powerful promise: once a person becomes a citizen, that person belongs to the country under the law. Rep. Nancy Mace of South Carolina is now challenging how far that promise should extend inside the federal government.

On May 20, 2026, Mace introduced H.J. Res. 188, a proposed constitutional amendment requiring members of Congress, federal judges, ambassadors and other Senate-confirmed officials to be “natural born citizens.” The resolution was referred to the House Judiciary Committee, where it has remained without further listed action.

The proposal would create a new constitutional barrier between citizens by birth and citizens by naturalization. It would not cancel anyone’s citizenship, but it could prevent naturalized Americans from holding some of the nation’s most powerful public offices.

Mace frames the proposal as a loyalty safeguard

Mace argues that officials who write laws, interpret the Constitution, or represent the United States abroad should have undivided loyalty to America. In announcing the measure, she said people holding power in the federal government should be natural-born citizens and accused some foreign-born lawmakers of placing other countries first.

She specifically targeted Democratic Reps. Ilhan Omar, Pramila Jayapal and Shri Thanedar, all immigrants who later became U.S. citizens. Her argument treats citizenship acquired through naturalization as legally valid but potentially insufficient for the highest levels of public authority.

The actual text is broader than a ban on naturalized members of Congress. It would prohibit naturalized citizens from serving as federal judges, including on the Supreme Court, or as ambassadors, consuls, and other officers requiring Senate confirmation. The judicial and executive-branch restrictions would take effect six months after ratification.

The phrase “natural born citizen” also deserves care. It is not always the same as “born inside the United States.” Some people born abroad acquire American citizenship at birth through a U.S.-citizen parent, depending on federal requirements, so birthplace alone would not automatically decide eligibility.

The Constitution currently opens Congress to naturalized citizens

Article I sets three main qualifications for the House. A representative must be at least 25, must have been a U.S. citizen for seven years, and must live in the state represented when elected. Senators must be at least 30, have been citizens for nine years, and live in their states.

There is no natural-born requirement for either chamber. The Constitution reserves that condition for the presidency, while the 12th Amendment says anyone constitutionally ineligible to be president cannot serve as vice president. Federal judges do not currently face a specific constitutional citizenship requirement.

That difference was not accidental. The Constitution Annotated explains that the Framers designed the House qualifications to keep eligibility open to merit, including both native-born and “adoptive” citizens, while requiring enough years of citizenship to build familiarity with the country.

Mace’s amendment would reverse that tradition. A naturalized citizen could vote, pay taxes, serve in the military, build a business and participate in civic life, yet remain permanently excluded from writing federal laws or interpreting them from the bench.

Critics say the measure creates two classes of Americans

Jayapal, who became a citizen after immigrating from India, called the proposal “narrow-minded” and “xenophobic.” She argued that it insults naturalized lawmakers and the voters who elected them while ignoring the country’s long history of immigrant participation.

Omar offered a shorter response when asked about Mace’s effort: “Good luck to her.” The remark reflected the enormous political obstacle facing the resolution, even before the deeper constitutional and cultural debate begins.

To become part of the Constitution, the amendment would need approval from two-thirds of both the House and Senate, followed by ratification from three-fourths of the states. Mace’s resolution also establishes a seven-year deadline for state approval. That is an exceptionally high threshold, and the measure has not advanced beyond committee referral.

The amendment’s wording is party-neutral, so its reach would not stop with the Democrats Mace named. Any officeholder who obtained citizenship through naturalization could be affected, regardless of political affiliation.

The controversy therefore reaches beyond one lawmaker or one party. The central question is whether citizenship should provide equal political membership or whether certain offices should remain closed to Americans who were not citizens from birth.

Mace presents the amendment as protection against divided loyalty. Her critics see a presumption that immigrants can never be trusted as completely as native-born citizens, regardless of how long they have lived in the United States or how voters judge their service.

For now, the proposal is far from becoming law. Yet its symbolism is immediate. It asks Americans to decide whether naturalization represents full entry into the national family or a permanent second tier of citizenship with a ceiling that even democratic election cannot break.
