A well know notary from San Francisco referred me to Wilson...and so glad he did. I’m currently working on my Green Card and everything is going smoothly. Elvia Medrano (Google 5-Stars Review)


Christopher represented my family's immigration case which was in the most critical step of the process. He is extremely knowledgeable in what he does and was able to handle our case, and win it, in a quick and professional manner. I strongly recommend Christopher as an attorney. - Anastasia


My wife and I are working on my wife’s green card case. So far, our attorney, Wilson, and case manager, Rory, have been on top of it! Very professional, reasonable price for great service. I am confident in our case now that KPB law has it in their hands. We’re doing the marriage based green card. Hoping for speed! But that’s up to the government officials. Thanks KPB! Noah Godby (Google 5-Stars Review)
