• A Certificate of Mexican Nationality by Birth is an official document issued by the Mexican government that certifies a person's Mexican nationality by birth.
• This certificate serves as proof of Mexican nationality and is often required for legal and administrative purposes, such as obtaining a Mexican passport, applying for certain jobs, or registering for educational programs in Mexico.

• Mexico allows for dual nationality, which means that individuals can hold citizenship of Mexico and another country at the same time. Holding a Certificate of Mexican Nationality by Birth can be the first step in obtaining Mexican citizenship and, ultimately, dual nationality.

• This certificate is used as a proof of identity.
