James was born in Albany, Georgia. He earned a Bachelor of Arts, with a double major in English Literature and in History, at the St. Mary’s College of Maryland in 1997. Subsequently, he became a high-school teacher and taught in Japanese public schools for three years through the Japan Exchange & Teaching (JET) Program. Afterward, he taught middle and high school students at a private school in Tokyo, spending a total of almost a decade living and working in Japan.

James returned to the United States in 2007 to attend law school at the University of Colorado – Boulder. For his volunteer work, he was awarded the Argosy Distinguished Volunteer Award by the Center for Energy and Environmental Security (CEES). It was in law school that James discovered his true calling: immigration law. In addition to his coursework, James interned at the Immigrant Legal Center of Boulder County and, after being licensed to practice law, took pro bono cases from the Rocky Mountain Immigrant Advocacy Center (RMIAN).

James has many years of experience working on immigration cases, including removal (deportation) defense, family-based applications, and business / employment issues. He is admitted to practice before the federal Tenth Circuit Court of Appeals and the federal District Court for the District of Colorado.

James is also active in the local, legal community. He currently serves on the Executive Committee of the Colorado Chapter of the American Immigration Lawyers Association (AILA) and is the former Chair of the Colorado Bar Association's Immigration Law Section. James has been a speaker for Continuing Legal Education (CLE) Programs through both AILA and the Colorado Bar Association and has trained volunteers to assist noncitizens through a variety of workshops and other legal assistance programs.

James is fluent in Japanese and speaks some Spanish.

Wonderful Experience with an Excellent Attorney
I strongly recommend James lamb to be your attorney for any immigration related matters. James has been my lawyer since 2015. He is very knowledgeable and responsible advocate. He prepared and filed my immigration applications successfully on time. James has always responded to my calls and emails on time and followed up on my requests with details in a very professional manner. His valuable legal consultations helped me in many situations. Even though I had moved to a different state, he traveled to represent me when I needed. I am very satisfied by his legal service, and I highly recommend him to anyone needs an excellent lawyer because the outcomes with James will be more than great.

Immigration Lawyer
James has provided excellent and agressive service for our case. Through his continious honesty and experience, James provided all the options available in order to attain the most effective outcome. We are very satisfied with the results of our case and the relationships we developed. James demonstrates his passion for helping his clients achieve their goals. We felt at ease at all times, never felt we were another case number. We highly recommend James Lamb as we couldn’t be happier for what he has been able to accomplish for our family.

Great lawyer, Excelent Service
I give James Lamb five stars. Lamb and his staff really came through for me when USCIS asked for further information before making a decision about my US citizenship. Lamb's knowledge of criminal law and how it may impact one's access to immigration benefits is very unique. I have met with other lawyers before reaching out to Lamb, but did not feel that they will really fight for my case. He met with me and dedicated all the time that it was necessary to understand my case thoroughly. In addition to his expertise, he also counts with very dedicated staff who do follow through and are available to offer when needed. Lamb gave me hope in pursuing my US citizenship, but he was also realistic and upfront about possible negative outcomes. I appreciate very much that it was never an issue to get a hold of him when I had questions about my case. Lamb won my case and I am forever grateful for that! As if this fact were not enough, during the process, I never had a doubt that he was working hard on my case because I was always being kept in the loop. I have no words to express my gratitude to James Lamb and his staff for helping me obtain my US citizenship and would (already have) recommend his to family and friends.
