One of the most efficient attorneys I have encountered. I contacted Mr. Valko regarding an O-1 visa extension. He was able to secure me a three-year extension. No attorney before him had even mentioned the possibility of it. It was my understanding that extensions were granted in one-year increments... only. I was very impressed with Mr. Valko' s speedy response - the extension was assembled in a two-week span, prompt communication, and accurate and thorough work. I have met and worked with several prominent attorneys in the past three years, on an O-1 visa, and subsequently an I-140 petition, still in the works. Martin Valko is the one attorney I would recommend without hesitation, and whom I would trust with my documentation in the future.

I would like to thank Mr Valko and his staff for all the help and support that they did for me and my case. I came with J1 visa and over stayed. My visa was not a subject to 2 years of home residency and Chavez & Valko services helped me to prove that, and prepared all papers I needed for the inte...rview. Ms. Cielo Pineda and Ms. Liset Lefebvre were always there for me to answer any of my calls and emails concerning my legal matters. I was very satisfied with their services and I thank Mr. Valko for all his help and advice. I got my Green Card just in a few months after we applied. I strongly recommend this legal office. They were very professional, polite, and gave me a good price. Thank you again. Sincerely L.

I cannot recommend Mr. Valko enough! He did an excellent job at helping me with my adjustment of status process. He was knowledgeable, professional, quick, responsive, and effective. He worked relentlessly since our very first exchange; he was able to give me his advice, but also listen to my ideas a...nd work with my specific situation. His paralegal was extremely helpful, professional and organized, and helped me make sense of the paperwork needed. the experience can be stressful and overwhelmed, but they went above and beyond to limit that as much as humanly possible. I was approved for residency very swiftly and his assistance at the interview was very beneficial. I wouldn't hesitate to hire them again and recommend them to anyone who needs an immigration lawyer! A+++

I/my family have utilized the services of Martin Valko on two occasions in the past 2 years - firstly, to secure an O-1 Visa & more recently to gain the EB-1 extraordinary ability alien permanent residency (Green Card). Throughout the process Martin & his staff were professional, courteous, consisten...t sources of updates/information & ultimately highly professional. The Chavez & Valko legal practice are in our well travelled opinion THE most professional & knowledeable on such Life-changing immigration matters which require such acute support & understanding (and we tried other attorneys who fell well short of the mark). The result of these endeavors are Green Cards for our family with permanent residency in the USA - an emotional roller coaster of a ride and one we would not have completed without Martin Valko. For that we are eternally grateful & i/we highly recommend Chavez & Valko to anyone seeking immigration counsel here in the United States. Thank you Martin Valko for assisting in greatly changing our lives in the most positive way!

Mr. Valko is one of the BEST immigration attorneys in DFW Metroplex. He is readily available through emails and the good thing is you do not have to go through paralegals to get him to answer any query for you. In my case, he has answered my questions, beyond consultations, even in the night. He is a... very confident professional and takes your case very seriously and would never misguide you. I use him for any employment-based legal questions, with utmost trust. Highly professional and successful firm !!!!
