Practicing immigration law is a very personal profession for me. My parents both immigrated from Germany in the 1960s, so my sister and I are first-generation Americans. My wife was born in Russia, and has since become a naturalized U.S. citizen. Our two children are growing up in a multicultural Russian-German-American household, and I believe that they benefit from it. Having such real-life connections with the immigration experience allows me to understand my clients' concerns and perspectives to a personal degree. My many years of experience with all kinds of employment-based and family-based immigration matters have provided me with a great deal of knowledge and comfort in representing my clients to an exceptionally high standard.
