Mexican Nationality Law - Multiple Nationality

Multiple Nationality

The Mexican nationality law acknowledges that a Mexican by birth may possess another nationality. If that is the case, however, such an individual must always enter and leave the country as a Mexican (by presenting a Mexican proof of citizenship). The law also established that regardless of possession of another nationality, an individual will always be considered a Mexican national and or cannot claim protection from a foreign country in certain cases:

• participating in capital of an entity or a company if they are constituted according to the Mexican law; if
• giving credits to such entities; and if
• possessing property in Mexican territory.

All Mexican nationals by birth who possess another nationality cannot be elected for or work in public office only in those cases that the law clearly establishes that they must not acquire another nationality. If in such a case, she or he can request a Certificate of Nationality from the government, renouncing the other nationality.
