I cannot recommend Sintsirmas & Mueller Co., L.P.A. highly enough. From 2018 through 2024, Spiro and his outstanding team guided my wife, my stepson, and me through a long and complicated immigration journey with expertise, patience, and genuine compassion. For my wife, they expertly handled: • Marriage-based Green Card (Adjustment of Status) • Multiple address changes with USCIS • Naturalization (N-400) application and citizenship interview preparation • Numerous USCIS inquiries and resolution of extended processing delays For my minor stepson (living abroad when we began), they managed the entire consular processing case that ultimately led to his Green Card as the child of a U.S. citizen, including: • Preparation and submission of all National Visa Center and U.S. Consulate documentation • Consulate interview preparation • Clear explanations of how the Child Citizenship Act of 2000 would apply once he entered the U.S. with his immigrant visa Thanks to their thorough work, my stepson received his Green Card shortly after arrival and automatically became a U.S. citizen under the Child Citizenship Act because his mother (my wife) had already naturalized. After more than five years of paperwork, interviews, and waiting, our family is finally together—and all of us are U.S. citizens living happily under one roof. We genuinely did not think this day would come without the diligence and skill of this firm. Spiro answered literally hundreds of questions over the years—often the same ones repeated out of worry—with unwavering professionalism, clarity, and kindness. Everyone at the firm treated us with respect, empathy, and dignity during what was, at times, an overwhelmingly stressful process. Sintsirmas & Mueller didn’t just represent us; they became true advocates and friends. We will be grateful to them for the rest of our lives. Thank you from the bottom of our hearts. Kyle & Sumy

I wanted to hire this firm to handle my immigration moving forward. I gave my information to the customer service person and was told a lawyer would reach out to me in 24 hours. After waiting 48 hours, I called them again. This time the customer service person said they are not sure why no one has reached out to me yet. She was now going to give me an email to try to get in touch with someone. It's clear that they have their hands full and do not want new business. Either that or their appointment system is broken and needs a rethink. Update: a couple hours later, they did call me to let me know they did not provide the service that I needed, despite their website suggesting they do. Your mileage might vary.
I cannot thank Spiro and Anna enough for all the guidance and support they have given me and my spouse in the process to get the U.S. green card. They have been with us every step of the way and made the immigration process as easy as it could be. Whenever we had issues during the application for a green card, they were always able to quickly resolve the problem! I highly recommend using Sintsirmas Immigration Law Co. LPA if you have an immigration case - Spiro and Anna will have your back!
My wife and I worked with Spiro and Anna through the immigration process and we could not be more pleased with the service. Spiro is a consummate professional and a peerless expert when it comes to understanding immigration law, and he gave us the confidence guidance we needed to navigate the lengthy and stressful undertaking with ease. Anna was instrumental in helping us get all of the paperwork filed correctly and swiftly, and we are so grateful! Thank you both again for everything! If you are looking for an excellent law firm to help you succeed in the immigration process for reasonable rates, look no further.
We had an amazing experience with Spiro on our immigration case. He was incredibly responsive answering all of our questions. His advice was spot on and helped us feel confident every step of the way. Highly recommend him to anyone needing immigration help.
