Does Mexico allow dual citizenship? (2026)
Yes — Mexico has allowed dual nationality since 1998.

Mexico allows dual nationality. Since 1998, Mexicans by birth don't lose their nationality by acquiring another, and you can naturalise elsewhere while remaining Mexican. Mexico taxes on residence.
Does Mexico allow dual citizenship?
Mexican law preserves the nationality of Mexicans by birth even when they take another citizenship. Foreigners naturalising as Mexican are generally asked to renounce, but Mexicans acquiring a second nationality keep theirs.
The catch to watch
Mexican nationals are expected to enter and leave Mexico on their Mexican passport. Tax is residence-based, so a second passport doesn't create Mexican tax exposure by itself.
How dual citizenship arises
By birth in Mexico, by descent from a Mexican parent, or by naturalisation.

Frequently asked questions
Does Mexico allow dual citizenship?
Yes — since 1998 Mexicans by birth keep their nationality when acquiring another, so dual nationality is allowed. Foreigners naturalising as Mexican may face renunciation requirements.
Do Mexican dual nationals pay Mexican tax abroad?
Mexico taxes on residence, not nationality, so living abroad and ceasing Mexican residence generally ends Mexican tax on foreign income.
Which passport should a Mexican dual national travel on?
Mexican nationals are expected to enter and exit Mexico using their Mexican passport, even if they use another passport elsewhere.
