Make sure you study vocabulary, terms, and phrases related to immigration and citizenship, as most of your interview will cover those topics.

If you are applying for citizenship because of your marriage to a Mexican citizen, you must be able to prove that the two of you lived together as spouses during the 2 years immediately preceding your application. If you are awarded citizenship because you made an outstanding contribution that benefited Mexico, there is no residency requirement. These citizenship awards are typically bestowed upon celebrities and industry leaders.

Once your application is reviewed by an SRE official it will be submitted to the Ministry of the Interior for approval.

The SRE doesn’t offer a timeframe of how long it takes to get a letter of approval.

If you won’t be able to attend on the date your interview and exam are scheduled, contact the SRE as soon as possible and ask to have it rescheduled. If you don’t pass either the interview or the exam, you must wait at least 10 business days before you can apply to take them again. You will also have to pay the application fee again. If you fail the interview or the exam twice, you have to wait one year before you can apply for naturalization again.

If your application is approved, a certificate of naturalization will accompany the letter. You can use this certificate to apply for a Mexican passport. If your application is denied, the notice will provide you with the reason for the denial. You’re welcome to apply again after waiting at least 10 business days. [9] X Research source
