For marriages between foreigners, the acquisition of Mexican nationality by one of the spouses after the marriage will permit the other spouse to obtain nationality, provided he/she meets the requirements of this subsection; and

If the person exercising parental authority has not applied to have his/her adopted children or the minors naturalized, they may apply for naturalization within one year after the date on which they reach the age of majority, in the terms of this subsection.

Need for the Document[edit]

Naturalization (or naturalisation) is the acquisition of citizenship and nationality by somebody who was not a citizen or national of that country when he or she was born.
The naturalization certificate will be valid starting on the day after it is issued.
Anyone who acquires Mexican nationality may retain it, even after a divorce, except in the event that the marriage is annulled for causes attributable to the naturalized spouse.

Information which might help[edit]

Mexican naturalization offers several benefits to foreigners.
Among them (in no particular order of importance): you can vote, change address or jobs without having to inform the National Institute of Immigration (INM) of your every move, wait less time in immigration lines at airports, and avoid having to pay to change your immigration status and/or renew your visa each year to extend you stay in Mexico.
