The Mexican Congress is advancing a constitutional reform championed by President Claudia Sheinbaum to require individuals running for the presidency, state governorships, or head of government of Mexico City to hold exclusive Mexican nationality. Candidates would be legally required to completely renounce any foreign citizenship or nationality prior to registering for office, and would be barred from using foreign passports or seeking diplomatic protection from another state. The initiative has cleared both the Chamber of Deputies and the Senate by the necessary qualified majorities and requires ratification by a majority of state legislatures to become part of the constitution. Proponents frame the measure as protecting national sovereignty, while opposition lawmakers argue it undermines the political rights of citizens living abroad and dual nationals.
