``Having visited several law firms and having come out each time more confused, I met Alexandra. From the first moment she explained my alternatives and the process to follow to get my visa with complete clarity and simplicity. She took care not only of the endless paperwork but Mercado & Rengel helped us create a great business plan for my E-2 visa, which was immediately accepted and approved by the American Embassy in Madrid. I was granted a visa for five years when most of the people I've met in the United States would grant only get three years. Without a doubt I will work with Alexandra again.``

``Professional knowledge, great personal attention, and proven experience are values of Mercado & Rengel; who gave me the opportunity to get my Business Visa for USA. Good job Ivan!! I highly recommend your services to anyone who needs advice with immigration matters. Thanks!!``

``We have been working with Mercado & Rengel for over 4 years in an Immigration petition for my son. It has been a long process during which he has gone from a Temporary Resident Visa to Permanent and to getting American citizenship. The firm's work has been very professional and helpful to us at all times and they have done a brilliant job. It was an added benefit that the attorneys themselves were able to able to speak in Spanish and in English . We will always be very grateful to them!!!``

``From the beginning I knew that I needed a good lawyer to navigate the immigration laws of the US and get a visa. While I was doing my MBA in Madrid, I met Alexandra, and she and her team did a great job for me. I had heard many stories of the high costs of lawyers, process that extended to 10 years and frankly I was scared. Deciding to immigrate was a big step, it is complicated enough to adapt to the way of doing things in American (it is a very developed and specialized system), but to also have to worry about my immigration status is daunting. Mercado & Rengel took a huge load off me. Thanks Alexandra and Ivan.``

``For years I planned to start a business in the United States, but needed someone to guide me in this adventure. It was not easy, and Mercado & Rengel has played a very important role in my success. They helped me with commercial negotiations, permits and the visa needed to get started. I am very grateful to them for all their help.``

``Thanks to the hard work of Mercado & Rengel on my case I can rejoin my family in the United States and my daughter can get to know her grandparents. My case was quite complicated but effective work and professionalism made for a great outcome. Thanks to Alexandra for your help and advice not to give up on this long and complicated immigration process. We would also thank Ivan for his speed in helping finding solutions at certain times in the process. I look forward to working with Mercado & Rengel in the future.``
