I will be very honest, at first I didn't even think that this place was legit, it was just me thinking that. I did research on it and found good positive reviews and decided to give it a try. The… initial process was super easy, everything is done via email at first or throughWhatsApp. Once they checked my cases which were for my daughter, son and wife, they said that I just needed to get a signed birth certificate from the hall of records in San Bernardino for my daughter. After that, I had perfect cases. For my wife they recommended that my suegro should apply for her but for my kids I did it. The process took one month and everything went super smooth. I paid half of the fee to start the process and the rest after receiving the certificates. I absolutely recommend DNE, these guys are very professional y amables tambien. Vale totalmente la pena. Les di 5 de 5 estrellas. 👌👍read more

I never felt alone during the process and I would recommend this service to other family members and friends. Great job you guys, and thank you.read more

I highly recommend utilizing DNExpress for anyone trying to obtain their Mexican citizenship. In my case both of my parents were born in Mexico and had never registered my birth as a Mexican born… abroad. DNExpress handled everything! They will communicate with you in the initial review of your case and if you decide to proceed they will let you know what documents you need to obtain and they handle the entire process for a very reasonable fee. I was fortunate to receive my Mexican citizenship and the corresponding paperwork much faster than initially quoted. If you’re on the fence I would recommend to reach out to them so that they can review your case free of charge. Thank you so much DNExpress!read more

This company is amazing! I did a quick scheduled interview over the phone. Got the information I needed uploaded to them, then they let me know I was a perfect candidate due to having all the needed… docs ready to go. I paid them 50% up front, then sent my US birth cert to them, they received it and gave me confirmation. 3 weeks later, I receive confirmation that my Mexican BC is ready and sent me a scanned copy to double check it for accuracy and submit my final payment. I’ll be getting the original paperwork soon. So excited to have my dual citizenship. My birthright.I highly recommend them. They make the process so easy. 5/5 stars!!read more

DNExpress was extremely helpful. I was worried the process of getting my husband’s Mexican birth certificate would be extremely difficult due to his mom changing her name when she naturalized as a US… citizen but they handled all of it for us and walked us through everything we needed to do. The turnaround for getting his birth certificate was extremely fast! I’m very happy with their services and will be using them again for my children’s documents and my residency.read more

Trabajando en mi español diariamente! My husband got his duel Mexican citizenship today! Next is his passport and my citizenship! ¡Viva la México! 🇲🇽DNE did an amazing job helping… my husband through me by proxy. His father is no longer with us but was born so long ago his Mexican Birth Certificate was never digitized. DNE had boots on the ground in the city he was born in, had them search by hand for 3 weeks in old church and hospital records. They found it! From there they digitized it and then proceeded getting my husband his duel citizenship. We tried going though a consult but they were no help with finding his dads records. They also wanted all of his mother’s records which had nothing to do with his Mexican language. This process was not fast, most because of the search and having to get a TX birth certificate apostates and were in Alaska. But none of that was DNEs fault. That’s just the way it is! Again thank you! Anyone who has doubts, don’t this is so legit. I will also be going though them to help with getting me my permanent residency then my naturalization paperwork. I am Mexican by marriage! 🇲🇽read more

I am deeply grateful to DN Express in Tijuana and Chula Vista, CA, for their outstanding service. Our facilitator, Ivonne Ramírez, made the entire process seamless and efficient. She guided me… through correcting inconsistencies in my U.S. birth certificate, which allowed me to successfully obtain my dual citizenship from Mexico.DN Express also assisted my husband with the paperwork for his TP residency card, and he was equally impressed with the personalized service. Ivonne patiently walked us through every step of the Mexican immigration process, ensuring we understood each stage clearly.We couldn’t be happier with the professionalism, care, and dedication we experienced. Thank you, DN Express and Ivonne, for making a complex process feel manageable and stress-free. Highly recommended!Which so much Gratitude,O and A. 🇲🇽🫶🦅read more

I obtained my dual citizenship with DNExpress and had a very pleasant experience!I appreciate how helpful and clear they were with explaining the steps during the consultation over the phone before… I started my process. I understood it was to be a silent process and they'd reach out to you once it was complete, which made me nervous at first, but they really came through.All in all, my process was completed in about five weeks!I then recommended them to others who also had great experiences with them 😊read more
