Filex Sanchez

– Founder and Certified Specialist in Immigration and Nationality Law

My parents were immigrants to the United States, and I appreciate all of their hard work to be able to offer my family a better life. My father founded his immigration consulting practice in 1972 and taught me everything he knew about the process of immigration. After I attended law school at the University of San Diego, I thought I was going to go into corporate law, but after a short time in that field I missed something. In immigration law, I am able to make a profound impact on the lives of individuals, and that is extremely rewarding. This is why I do what I do. I’m in the business of uniting families, realizing dreams, and securing futures for the next generation of Americans.

My parents were immigrants.
I understand your challenges.

– Filex Sanchez, Esq., Founder and Certified Specialist

Union Law Group is the culmination of all of my years of education and hard work, as well as the tremendous work and effort of my parents. I am honored for the opportunity to serve my community and make a difference in the lives of so many hardworking families.

Guillermo Carrasco – Attorney Licensed to Practice in Mexico Only

I was born and raised in Tijuana, and living in the busiest border-crossing city in the world inspired me—I wanted to pursue a career where I could work with people in both sides of the border. I am a licensed attorney in Mexico with a L.L.M from the University Of San Diego School Of Law. My first job was as a junior associate at a top firm in Tijuana. Having immigrated myself, I am eager to help clients navigate the immigration process.

Today I lead the Tijuana office for Union Law Group where we assist our clients with all aspects of Mexican and international law.

When I am not in the office you can find me outside, surfing or logging miles on my bike training for a triathlon.

Leonardo Cortés – Assistant Manager

I graduated from the Baja California State University with a degree in law. I then began my career working with Cortes y Tapia Law firm in Tijuana, where I developed an interest in international law. After that, I gained valuable experience working with the Mexican Government Secretary with the National Immigration Institute (INAMI), learning how to help people from all over the world immigrate to Mexico, gain work permits, residency and citizenship.

Since joining Union Law Group in 2013, I’ve continued to consult and support individuals needing service in either Mexico or the United States. After moving to San Diego in 2015, my greatest passion is still helping the immigrant community. I like to travel read, do outdoor activities and always enjoy a good happy hour with friends.
