Mexican President Claudia Sheinbaum has sent Congress a constitutional reform proposal that would require candidates for the presidency, state governorships and the head of the Mexico City government to formally renounce any other nationality, placing exclusive Mexican citizenship at the centre of eligibility for the country’s highest elected executive offices.
The initiative seeks to establish explicitly in the constitutional text that these posts of popular representation must be held exclusively by Mexican citizens by birth. Sheinbaum argued that existing legislation contains gaps that allow sitting authorities to retain citizenship of other countries at the same time, creating what she described as a potential duality of geopolitical commitments.
According to the proposal, national sovereignty requires that the loyalty and supreme interest of those leading the executive branch rest solely with Mexico. The measure is intended to prevent possible vulnerabilities to foreign pressure or interference and to ensure that political command and strategic decisions remain tied exclusively to the Mexican nation.
Under the proposed reform, candidates would have to formalise the renunciation of a second nationality when registering their formal candidacy before electoral authorities. The requirement would therefore apply at the point at which candidates seek to enter an electoral contest, rather than simply imposing a general restriction on individuals who may hold more than one nationality.
Sheinbaum has also raised questions about the suitability of opposition figures based abroad seeking high public responsibilities. Asked about the potential impact on such figures, she pointed to the ethical and operational difficulties involved in pursuing major public office from outside the country.
The initiative comes amid a broader argument from the president that public office carries obligations extending beyond individual political ambitions. In previous days, Sheinbaum said those holding public functions had an ethical responsibility to prioritise citizens’ needs over political or individual aspirations. Through her official channels, she emphasised that no particular interest should be placed above collective well-being and the State.
The timing of the proposal also coincided with a political controversy involving Sinaloa Governor Rubén Rocha Moya, who resumed his duties after a 112-day leave stemming from accusations by US authorities over his alleged links with organised crime structures. Sheinbaum said she learned of Rocha Moya’s return at the same time as the public, through social networks, and categorically ruled out prior communication or consensus regarding the regional leader’s decision.
The episode added a political dimension to the president’s warnings about the responsibilities attached to public power. In a message published on X, Sheinbaum warned of the risks of government exercised without guiding values, stressing that command responsibilities are temporary while commitment to the homeland remains indefinite. She also argued that popular sovereignty should not be instrumentalised for particular projects.
Her message framed the proposed nationality requirement as part of a wider principle concerning the exercise of public authority. The proposal is based on the premise that those occupying the country’s most important executive positions should have an exclusive national commitment and should not face circumstances in which obligations or interests connected to another nationality could complicate that responsibility.
The constitutional reform will now follow the ordinary legislative route. The ruling bloc holds majorities in both chambers, pointing towards a potentially fast legislative process, although the proposal will also face public scrutiny before the next electoral cycles.
The coming debate will determine whether exclusive Mexican nationality for those seeking the country’s highest executive offices becomes a permanent constitutional requirement. At its core, the proposal seeks to turn a question of political loyalty and national sovereignty into an explicit test of eligibility for public power.
