30 Years Human

Resources Experience

Compliments and Reviews

Much appreciated comment on a large Yahoo web board: "I have to chime in with my positive experiences as well. We've used Sonia for a variety of things over the past three years - visas, address changes with IMS, Seguro Popular, drivers licenses, etc. - and only had positive experiences. We could probably field some of these things ourselves at this point, but her pricing makes it seem better to let her handle everything with the assurance it's being done correctly. She makes it so very easy!"

As posted on a major web board..... Sonia Diaz has helped me get my Permanente, MX drivers license and Seguro Popular. Because she is so experienced and knowledgeable, the speed with which she is able accomplish whatever you need in a minimal amount of time. She is amazingly fabulous! Any questions, contact me!​

Dear Sonia, 

Please know that working with you is a pleasure.  You make life easier for everyone. It is easy to see that you make life easier for Glenn and me, and you also make life easier for the people and institutions we have dealt with.

Just as important as insurance for me is maintaining my hair.  I absolutely love my new salon and I especially love Ramon.  I could never have found them without your recommendation.

Thank you, Sonia, I appreciate you.

Hola Sonia

I want to tell you how much I appreciate all your help! There is no possible way I would be holding my permanente in my hand without you.

You are incredibly great at getting these things done!

Thank you so very much,

June 1, 2018


You're the poster child for being professional and on time - thanks for your help.

We’d be TOTALLY FLOUNDERING without their knowledge, CARE and conscientiousness.

Our Amazon Book Reviews: The Move to Mexico Bible

Glenn Wilson: The Move to Mexico Bible is a great resource if you have recently moved to Mexico or are thinking about moving to Mexico.
We moved to Mexico about a year ago and Sonia Diaz (one of the authors) was a tremendous help with the transition and visas, medical insurance and more. This book contains facts, information, resources and some very useful advice and opinions.

​Thomas R. Kluzak: Thorough discussion of the country and the complexities of relocating there. I expect it to be very useful as we consider our move.

Thank you Sonia to you and your husband for taking us to get our blood tested and then on to get our driver’s licenses. Because of you it was a fast and easy process. We will recommend your services to those we know and look forward to future interactions with you.

We want to thank you for your professional and very well organized assistance with our permanent residency applications. We look forward to seeing you in a few weeks to continue the process.
If we find anyone in the SMA area who needs help with this or any similar situation, we will gladly refer them to you.
Warm regards,

Yesterday Teresa went with me to Aduana to sort thru the issues relative to my TIP. The fellow that initially tried to help us was giving me what I knew to be bad advice. He was very nice and polite but he was incorrect. Teresa’s persistence, professionalism yet courteous approach provided us with what we believed to be the appropriate steps to take to insure the return of our deposit. 
Your company along with Teresa will be a welcome addition to Puerto Vallarta. 
Thank you,

Over the past couple of months Sonia has been helping me on a process of obtaining Mexican citizenship. She is an absolute Marvel. From day one with her introductory letter explaining every step of the process down to taking me to Queretaro twice as well as her sister helping me in Mexico City she has been amazing. There was only one thing she could have done better, take the exam for me. But since that wasn’t possible I can only highly recommend that you seek her out for any sort of immigration or naturalization work you might need to be doing.

​Giorgina   Sonia Diaz - Professional Consulting Discover San Miguel de Allende July 30, 2019 at 6:54 am

My husband and I had a very good experience with Sonia Díaz. She secured our visas within a reasonable time. She is very professional, spells everything out, and is responsive to your questions and concerns.​

Dear Sonia,
I just want to thank you for your help in getting our Seguro Popular renewed. Mary Jordan and I had a lovely experience with Tere. She was prompt, efficient, very pleasant and made this experience very comfortable for both of us. She is a very good employee and I will be more than happy to refer my GTO friends to your services in Puerto Vallarta. 
Again, my great thanks and appreciation.

Brad Duncan Can't say enough great things about your service. Teresa took care of everything we needed to get our resident visas and update our address when we moved. Thank you for making our transition from the U.S. to Puerto Vallarta so easy.

​Arden Beere Trevino Sonia has been so very helpful to us! Always pleasant, understanding and prompt!

Patty Wolfston-Hawco You provide excellent service and communication!

Nureshmi Hassim Teresa Sanchez has helped at least two people I know. She very professional and dedicated to getting it done.​​​​

Narae Kim Ellis I always recommend Sonia, Sonia, and Sonia. Just don't waste time going elsewhere.

John Walker  Sonia is my go-to person for everything in Mexico even though I have good Spanish. On several occasions, going it alone has cost me dearly in the past and Sonia's relationships with the various authorities/agencies helped to bail me out each time. Don't hesitate. Her fee is trivial in comparison to the hassle you will avoid.

Mike Wright  Hi Sonia, I just wanted to post that this past Monday my wife and I met with Teresa at the INM office in Nuevo Vallarta. 
We arrived at 8:30 am and walked out at 11am with our PR cards!!

The connection with you and her work with us far exceeded any expectations we had and we just wanted to say muchas gracias from the bottom of our hearts. She was extremely personable and professional and we will recommend your and her services to all we meet that are looking to get their residency here in Mexico.​​

​Beverley Pope: I can definitely recommend contacting Sonia. We used her local agent in PV, Teresa. She’s very efficient and fees were lower than another we contacted.

March 14, 2021 Philippe Di Pizzo: I usually do everything on my own but this time, I had Tere help me with my permanent residence in Nayarit, as I wanted to avoid going back and forth to the Immigration office for whatever reason. A few emails with Tere, and one and only meeting with her at the INM was all it took. I met her there at 8:30am and was outside the door with my PR card before 10am...I can't recommend her enough!

March 14, 2021 Becky Glover Herrin: And I can 1000% recommended Sonia Diaz, she helped us get our Permanent and Mexico driver’s licenses. No way I’d have had an easy time without a professional on the Mexico side, she’s awesome.

March 26, 2021 Testimonial: 
My husband and I highly recommend Sonia Diaz. We quizzed our friends in San Miguel about the best person to help us through the process of obtaining our Residency Visas and Sonia Diaz was the first choice from everyone.
We found Sonia’s professional and straightforward manner to be very reassuring. We felt that we were in capable hands from our first email interaction, all the way through to completion with Residency cards in hand. 
It is easy to understand why Sonia is so highly sought after. If you are fortunate enough to work with Sonia, you will find that she is highly organized and always up to date with the constantly changing residency requirements in Mexico. Every step of the way, you can always trust that Sonia will let you know exactly what is required. 
We also recently had Sonia guide us through the process of obtaining our Guanajuato Drivers Licenses. Sonia, we simply cannot thank you enough for helping to make everything so easy for us!

I relocated to San Miguel 10 months ago and it finally became necessary for me to obtain a visa (i'm retired) and a Mexican drivers license. Trust me this process can be somewhat confusing. I was so very fortunate to be introduced to Sonia Diaz (in San Miguel de Allende) who provided not only terrific advice but personal attention to including everything necessary to obtain these important documents. Thanks to Sonia I'm now a permanent visa holder and have a Mexican drivers license. If you want a seamless process and work with a very nice professional, hire Sonia:)
thank you again

I often refer people to you, in both Puerto Vallarta and San Miguel. You are efficient, no nonsense, and your fees are always reasonable. We are grateful to have you as a resource Sonia. You never let me down.

Mexico has one of the world's largest economies, it is the tenth largest oil producer in the world, the largest silver producer in the world and is considered both a regional power and middle power. In addition, Mexico was the first Latin American member of the Organisation for Economic Co-operation and Development OECD (since 1994), and considered an upper-middle income country by the World Bank. Mexico is considered a newly industrialized country and an emerging power. It has the fifteenth largest nominal GDP and the eleventh largest GDP by purchasing power parity. The economy of Mexico is strongly linked to those of its North American Free Trade Agreement (NAFTA) partners, especially the United States. Mexico ranks sixth in the world and first in the Americas by number of UNESCO World Heritage Sites and Mexico is one of the top ten most visited countries in the world with approximately 27 million international arrivals per year. According to Goldman Sachs, by 2050 Mexico could become the world's fifth largest economy. PricewaterhouseCoopers (PwC) estimated in January 2013 that by 2050 Mexico could be the world's seventh largest economy. Mexico has membership in prominent institutions such as the UN, the WTO, the G20 and the Uniting for Consensus.

Mexico, officially the United Mexican States (Spanish: Estados Unidos Mexicanos), is a federal republic in North America. It is bordered on the north by the United States; on the west by the Pacific Ocean; on the southeast by Guatemala, Belize, and the Caribbean Sea; and on the east by the Gulf of Mexico. Covering almost two million square kilometres (over 760,000 sq mi). Mexico is the fifth largest country in the Americas by total area and the 13th largest independent nation in the world. With an estimated population of over 120 million, it is the eleventh most populous and the most populous Spanish-speaking country in the world and the second most populous country in Latin America. 



What I Do



Your first Temporary or Permanent Resident visa starts with a pre-approval at a Mexican consulate outside of Mexico. I can guide you through this process and work with you once you are in Mexico. I also process visa renewals and replacements.

Car Registration 

Our four rescued dogs. These animals all deserve a home and provide so much love and joy. 

Available through Amazon, Barnes and Noble, Kobo, Apple Books, Chapters/Indigo, plus Target and Walmart web sites.

Our book is printed when ordered, meaning you have the latest version with updates. 

So, you’re thinking of moving to Mexico? Good for you. It’s exciting to plan your adventure and even more exciting to live it. Some questions to ask::

What will you do for medical insurance?
Will you be bringing your vehicle and pets?
Are you allowed to own property in Mexico?
How do you handle paying utilities?
Can you transfer money online easily?
How long can you stay?
Will you have to pay taxes?
Do you have enough money to live there?
And it’s a big country – living in Cancun is nothing like living in Cabo. The Move to Mexico Bible takes a look at 33 different cities and towns – from Ensenada to Tulum – exploring variables from expat population to climate and conveniences.

This book will also walk you through the legal process for obtaining your residency visa and will give you invaluable advice about health care, household help, communications, real estate and other topics of interest.

Sonia Diaz & Beverley Wood share their decades of acquired knowledge and personal on-the-ground experience in The Move to Mexico Bible.

Make your move to Mexico with confidence and ease using the information in this book.

My web site averages 200,000 views per year. My intent is to inform, to be concise and accurate. My information is based on extensive experience. Everything found here has been thoroughly researched. In San Miguel, I have more than 650 immigration processes annually. In addition, 250 more in the Puerto Vallarta area. 


I offer a range of consulting services, all designed to help you make your life in Mexico easier. Whether you are coming to Mexico for the first time to live or renewing a visa or seeking consultation I am here to help. Mexico offers many benefits to residents including healthcare, driver's licenses, car registration, opportunity to earn income and much more.


For those with a foreign plated vehicle it is understandable in many circumstances you may wish to keep your vehicle. The easiest method is to be a Temporary Resident visa which allows one to have a car from Canada or the United States, in Mexico for up to 4 years. 


If you wish to earn income including as a landlord while being a resident this is available to you. I will complete the your processes with Immigration. 


I have personally traveled in Canada and the United States. I understand the differences compounded by a language issue for many. This allows me to provide a professional service in a  timely manner.


Welcome to Mexico, my country, my home where the greatest consistency is inconsistency. I truly hope you come to appreciate all that Mexico offers including our people, culture, diversity, traditions, food, weather and geography.
