Mexico advances rule requiring presidential candidates to renounce dual citizenship

Mexico is fast-tracking a constitutional reform requiring presidential candidates to renounce dual citizenship, despite criticism it infringes on political rights and targets opposition figures. President Claudia Sheinbaum defends the measure, which also covers governors and the Mexico City mayor, as a safeguard against foreign interference. The reform, backed by Sheinbaum's Morena party, passed both chambers of Congress and was approved this week by a majority of Mexico's 32 state legislatures. Critics argue it erects hurdles for dual-national politicians and could hamper succession within Morena, where several figures hold foreign passports. Lawmakers must still issue a formal declaration of constitutionality before publication. The requirement takes effect for candidates in 2028, not affecting current officials or 2027 midterms. Mexican billionaire Ricardo Salinas, a vocal administration critic, suggested the bill targets his possible presidential run, though he later said he holds no dual citizenship. Mexico's current constitution does not bar dual citizenship for presidents, with only Cuba and Venezuela imposing such bans in Latin America.
