``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!!!

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.
