Excellent Services
I am a US citizen and wanted to apply for my husband to get his green card but my husband had a voluntary deportation and never left the country. I was told if you have a deportation on your record you are not allowed to return for 10yrs or more. He was detained 8yrs later and was in the process of being deported again. I had hired two different lawyers prior to meeting Catherine and just felt they were unorganized and were not doing enough to handle our case that was difficult. The first lawyer did not give us much hope and even recommended we move and live hiding, and failed to tell me we can appeal an important decision. Thankfully we met Catherine one month before my husband had to leave the country and she continued where the other lawyers left off. She worked hard on our case and was very knowledgeable, honest and organized. My husband had to leave the country and returned legally 2 yrs later. Would highly recommend especially if you have a difficult case.

Excellent immigration lawyer
I had come to cathy with little hope after a really bad experience with my last attorney. From the beginning, she was so helpful and supportive. She knew exactly what she was doing. She is confident and her work is always on the point. She is the best immigration lawyer for any kind of immigration issues. after almost 2 yrs, my husband and I got our green cards just recently and we are just so happy. I am referring any family and friend to her. I recommend Catherine highly and commend her for her excellent immigration knowledge.

Excellent Service
I had a great experience with Catherine Brown and her staff during the process. Catherine walked me through the process step by step in detail and explained my options during the consultation. Catherine and her staff were available to answer my questions and they were very responsive through out my case. All I had to do was submit the documents I was requested and Catherine took it from there. They literally made this process stressless. The prices were very reasonable too. I highly recommend Law Office of Catherine Brown.

Honest, prompt, direct and personable too!
Attorney Brown was very knowledgeable, and gave me advice in my best interest. She has an approachable personality, which made me feel comfortable talking to her about things I didn't know or understand. At the end of our conversation, her recommendation saved me significant amounts of money, and I think that is quite telling of a quality attorney. Highly recommend.

Permanent Visa EB2
I found Catherine Brown on She worked with me and my company to file my permanent visa (EB2). I have been working with her for about 2 years now and she is great to work with. She has a great attention to detail. She explained me the steps in detail and answered all of my questions, sometimes even the unnecessary ones. She has been very patient with me and warded off my worries, because I haven't been very lucky with visas. I definitely recommend her to anyone who needs an immigration lawyer.

THE Best immigration attorney
Catherine and her team were incredibly helpful assisting with the immigration of my wife. I am pretty versed when it comes to paperwork and documents, etc., however I do not know how I would have managed the handle the overwhelming amount of work, paperwork, forms, appointments, etc., etc. And that does not even include keeping up-to-date on the latest legalities. Catherine was always available, immediately answered all my questions and it seemed like she worked around the clock to make sure everything is taken care of and answered. I know we were not her only client but she made us feel like we were. Everything went as smooth, perfect and fast as possible. We are forever grateful and can't thank her enough what she has done for us.

Wife immigration case
Catherine was amazing! I have had a difficult case receiving an intent of denial for my wife I-130 application. After God help, Catherine did an outstanding job advising me to gather important information to appeal our case. In fact, the case with her hard work and follow up was then approved. She is easy to reach, friendly, caring about her clients. In addition, she helped my brother for his immigration legal resident approval nicely. Furthermore, her billing charges is very reasonable. she has a great team at her office that made my communication easy and positive. I have had multiple positive experience with Catherine and I recommend her highly for immigration cases.

Simply amazing.
I had high expectations dealing with a lawyer and some reservations too. Catherine exceeded all of what I had hoped to find in a immigration lawyer- she is outstanding. Even better during our initial consultation I knew I found the one. She is well informed. A great listener, intuitive in her answers and accurate with her advice and guidance. I do not believe you will find better and she even charges very reasonable rates. Do think, act, call Catheribe today.

If you need an immigration lawyer- STOP, you have found who you need. Catherine and her team are exceptional, dedicated, thorough and will get you where you need to be. I cannot speak highly enough of how this company, who under extremely complicated circumstances provided a solution, answered all of my questions going above and beyond time and again. This company is simply magnificent, where our experiences with other law firms were in a word- terrible. Do not hesitate - hire CB today.

Case for removal of conditions on my PR
Hello! This is Fareed! I processed my case with Catherine Olson Brown to remove the conditions of my PR after divorce. I am absolutely delighted to write that conditions on my PR have been removed, and Catherine has conducted my case in the most professional manner. She was also there for me in guiding me through the entire process, and never even hesitated to tell me beyond the scope of our case. I am looking forward to recommend her all my friends, relatives and anyone seeking a lawyer for any purpose.

Marriage based green card
Cathy helped my wife and I through the green-card process (through spousal sponsorship). Herself and Shannon were absolutely wonderful and helped us throughout, clarifying any questions we had, as well as keeping us informed about the status of our case. We both think very highly of Cathy and absolutely recommend her services.

Green Card Process
Cathy handled my green card case. She was recommended by a one of her peers. Her knowledge, professionalism and impeccable work ethic became apparent during our first meeting. Although the process was long and complex, Cathy and her team worked for me with passion, kindness and patience. They were always available to help and swiftly answered questions and requests without delay. Working with Kathy was a pleasure and I don’t have enough words of gratitude for her. I highly recommend Catherine Brown without reservations.
