If you marry a Mexican do you automatically become a Mexican citizen?

Answer 1

You don't automatically become a Mexican citizen just because you marry a Mexican. You need to apply at the Secretaria de Relaciones Exteriores nearest to where you live. You must live together in Mexico for at least 2 years during which time you need to have an FM-3 (which gives you permission to remain in Mexico for more than 6 months).

Answer 2

You never loss you citizenship, unless certain acts of war (treason, defection) are committed. No, if you marry to a Mexican in Mexico, you don't loss you citizenship. You should note, however, that he/she is not granted American citizenship automatically.

Answer 4

You are married, with certain rights such as common assets and that's it. Neither he/she becomes American, nor you become Mexican.
