What Our Clients Say

Reviews clients left for the firm on Google, quoted in full and unedited, newest first.

I got immediate approval of my naturalization interview thanks to the strategy and guidance provided by attorney Peng. I reached out to them about 24 hours before my scheduled interview and attorney Peng provided very professional and fast response which greatly helped my case. Highly recommended!

From the early consultation to the follow-ups, they were consistently responsive and proactive in answering all questions clearly and thoroughly.

We engaged Law Office of Attorney Peng for our L-1 visa petition, and the experience was outstanding. From start to finish, Attorney Carrie, Attorney Kong and the team demonstrated profound expertise and remarkable efficiency. They not only guided us meticulously through the complex application process but also provided invaluable strategic advice that went beyond the immediate case, helping us with long-term corporate planning. Their proactive communication and attention to detail gave us immense confidence. We highly recommend them to any company seeking top-tier immigration legal services.

Attorney Kong helped me complete two of my clients’ EB-5 direct investment cases. I believe there are very few bilingual law firms in the U.S. that can match this level of professionalism and responsiveness. Throughout the entire process, their team demonstrated an outstanding degree of expertise. I want to thank every member — Attorney Peng, Attorney Kong, and assistants Margaret Z. and Bailu — for their support to my clients. We have successfully obtained the conditional green cards. Attorney Peng is also a wonderful partner to work with. I highly recommend this firm to anyone seeking professional and empathetic legal services. Truly grateful.
