I have hired Mr. Yang to help me acquire permanent residency in the US. Mr. Yang was so professional and efficient in handling my case. He communicated with my employer and contacted all the experts who wrote the recommendation letters for me, and helped the procedure of my case go very smoothly. Mr.... Yang has extensive experience in immigration law practice, which gives him a thorough understanding of the entire immigration process. He is also well-versed in U.S. immigration policy, and keeps up with the latest trends in immigration law. From my first conversation with Mr. Yang, I immediately become aware of his integrity and commitment, making me feel that my case was the only one being handled by the firm; I was very impressed by the passion and patience for his work. Any concern I raised was immediately addressed by himself, not by secretary; and phone calls were always answered in a timely manner. Information I requested about the process was promptly forwarded. I have recommended him to my friends and colleagues, and there was never a complaint from them. Mr. Yang is simply the best.
