Mexico's reform to block dual citizens from running for president will take effect on Wednesday, amid criticism that the ruling party designed the move to block opposition candidates. The reform, proposed by President Claudia Sheinbaum, aims to prevent foreign interference. Opponents, however, argue that the move violates the rights of Mexicans who have migrated abroad and obtained citizenship in other countries, such as the United States. They also note that Mexico's Constitution already establishes nationality requirements for top positions.
The reform, approved by a majority of lawmakers and senators from the ruling Morena party and its allies, will apply starting in 2028. At that time, those with dual nationality must renounce any non-Mexican ties before running for any of the positions specified in the amendment. Next year's midterm elections, in which some state governor positions will be on the ballot, will proceed without changes.
