I've been working with Heidi and her team for 3+ years now, and I can say they are top notch. Heidi is extremely knowledgeable, she provides you with all your options, clearly explains the immigration process, and she really knows what she is doing, plus the fact that they treat every client like they matter, couldn't ask for a better immigration lawyer. The paralegals are incredibly knowledgeable, they work hard and are extremely organized. If you have any sort of immigration needs, I would highly recommend the law firm of Kodem Son Tang, they really are working for us!

Before working with Kodem Son Tang Law Group, we had a truly difficult experience with a previous immigration lawyer — it felt like we were talking to a wall because communication simply didn’t exist. Through a mutual connection, I was fortunate enough to meet Heidi, and from the very first conversation, I felt an immediate sense of relief and confidence that she and her team could truly help us with our visa filing needs.
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.
Heidi and her team have turned what used to be a stressful experience into a clear and reassuring one. We can’t recommend them highly enough. If you or your company are looking for an immigration law firm that truly cares, communicates, and delivers, look no further — they are the team you want on your side.

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.

Throughout the entire process, Shirley demonstrated the highest level of professionalism, efficiency, and attention to detail.

Beyond her expertise, Shirley is a true pleasure to work with—always responsive, patient, and genuinely committed to her clients’ success. I felt fully supported every step of the way, and I couldn’t have asked for a better advocate.
I wholeheartedly recommend Shirley Tang to anyone seeking expert guidance in U.S. immigration matters. She is truly exceptional.
