Everything we file
All Services
Most people arrive needing more than citizenship alone — a misspelled surname, a marriage never registered in Mexico, a name that changed in the U.S. We handle the whole chain. Prices are flat fees; government fees, where they apply, are quoted before we start.

Not Sure Which One You Need?
Most cases begin in one of three places. Pick the one that sounds like yours — and if none of them do, the free consultation exists for exactly that.
My parent or grandparent was born in Mexico
You are most likely looking at recognition of nationality rather than an immigration process.

Clear answers to the most common questions about our services, pricing and process.

Easy, please send us a picture or scan of: Your US birth certificate, your Passport*, and your Parent’s Mexican Birth Certificate(s). If you utilize your Spouse’s legal name please send us your Marriage Certificate as well. This is all we need to tell you if you are the perfect candidate. You can always contact us by phone, chat, or email us at contact@dnexpress.org.
** Passport is preferred but you can also send DMV ID, Military ID, or Passport Card **
We have helped people in this situation before. All we need is your parent’s Mexican Birth Certificate. First of all, if they have passed away, we express our condolences. Remember that we can help you even if they have passed away, guaranteed!
Also, if you do not speak to your Mexican parent, we can obtain your Mexican citizenship without bothering him. Remember that is your Constitutional Right to obtain your Mexican citizenship, not his/hers. So in these cases what we have done is (1) try to help you contact a relative of your parent which can provide your parents birth certificate or information so we can find the record for you. (2) If you have sufficient information about your parent, we can look for his record in Mexico. If this does not work nor apply to your specific case, please contact us, there are other ways we can help you. Cheer up!
Of course! The idea of dual citizenship is also a way to maintain a connection to the motherland and make it easier for future generations. Your children are eligible through at least one parent.
We get this question a lot, and the general answer, which applies to almost all our clients, is no — obtaining your Mexican citizenship does not affect your U.S. citizenship. Please review this official information from the U.S. government on the topic.
When you are born outside Mexico (in the U.S., for example) to a Mexican parent, you have the right to be recognized as a Mexican citizen born abroad. This is a direct path: you are not naturalizing, there is no oath or exam, and there are no high government fees or immigration process involved.
Note: this only applies if you are obtaining Mexican citizenship through naturalization, meaning via temporary or permanent residence. In that case you will face a renunciation clause when you apply. If you have a Mexican parent or grandparent, this does not affect you. If you are facing this scenario, please contact us.
