”Kodem Son Tang has assisted us in obtaining L visas on two previous occasions. Their extensive knowledge and contacts helped us to successfully obtain the visa, starting with selecting the appropriate visa type based on an understanding of our business background, and arranging meetings with experts in company formation and tax accounting. We were particularly impressed with: · The speedy response to our questions. · The preparation of documents in a much shorter time than expected. · The meetings to understand our business and introductions to relevant parties. · Preparing documents for embassy interviews and providing mock interview practice. · Providing and scheduling the necessary work for future visa extensions. Thanks to their meticulous preparation, even down to Plan B in case we received an RFE, we were able to apply for the visa without any anxiety. I would definitely use their services again in the future.

”It is with great enthusiasm that I write this letter of recommendation for Kodem Son Tang Law Group. A year ago, I found myself in a challenging situation that significantly delayed my Green Card process. I was at a loss, having consulted multiple attorneys, none of whom could offer a viable solution to help me and my family proceed within a reasonable timeline. Fortunately, that all changed the moment I reached out to the firm. From our very first conversation, I knew I had found a team that was not only ready to understand my situation but also willing to explore every possible avenue to move my case forward. They listened carefully, explained the intricacies of my case in detail, and together we decided which procedure to pursue. Kodem Son Tang Law Group guided me step by step through the entire process. What truly stood out was their dedication and attentiveness. They fully understood the urgency of my situation and were always available, often going above and beyond to provide timely, professional responses to my questions. On the rare occasions when they didn't have an immediate answer, they took the time to research and follow up with detailed explanations, ensuring I felt supported every step of the way. The process was intense and demanding, but thanks to their efficiency and expertise, it moved along at a remarkably fast pace. I am thrilled to share that just a month ago, my request was approved, and I am now on track to receive my Green Card. I am deeply grateful to Kodem Son Tang Law Group for their exceptional service. Their professionalism, dedication, and genuine care for their clients have been instrumental in my success. I wholeheartedly recommend them to anyone seeking legal assistance for their immigration needs.

”Kodem Son Tang Law Group is not only an immigration firm with extensive and outstanding knowledge in immigration law but also uses a warm-hearted, friendly, and detail-oriented approach to communicate with clients. Living in Washington D.C., there are quite a significant amount of legal resources to choose from. However, this firm is the one that always puts peace in my mind. There are rarely immigration firms that always answer your questions through email in a quick manner (most of them just ask their paralegal to reply). Even in situations when the team was on vacation or attending conferences overseas, they still responded to their clients. I strongly recommend Kodem Son Tang Law Group for their outstanding expertise and impressive warm-hearted communication skills.

Since working with Heidi and her team at Kodem Son Tang Law Group, everything has been smooth and efficient. Their responses are quick, accurate, and always thoughtful. Most importantly, we finally feel heard and supported throughout this complex immigration process.

I worked with Stephanie Vogt and Heidi Son on my EB-1 case, and I couldn’t have asked for a better team. Stephanie did an excellent job digesting complex subject-matter materials and crafting a compelling petition letter, while Heidi was always responsive and provided clear, professional legal advice. Their team, including their paralegal Miake in Japan, was exceptionally organized and detail-oriented, which made the entire process smooth and efficient.
My I-140 and I-485 were both approved with no RFEs, and my green card was approved this month (October 2025). I started working with them at the end of 2023 and have been consistently impressed by their expertise, communication, and care. I highly recommend this firm to anyone pursuing an employment-based immigration case.

Heidi is extremely seasoned, knowledgeable and an expert in navigating unique and tricky circumstances in the US immigration law. She got our PERM and I-140 petitions approved successfully despite several curve balls we've thrown her along the way in addition to the ongoing changes and uncertainties of the current US Administration and USCIS. Heidi always take the time and care to explain the situation in detail. She and her team are very responsive and her rates are also really reasonable. Out of dozens of professional services we hire over the past 12 years, Kodem Son Tang Law Group ranks within our top 3.
