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.

Ralf advised my question very clear. My questions was regarding my TPS and H1B status
"Ralf is extremely knowledgeable and well respected in the field of immigration law and I would highly recommend him to any individual or company who needs a lawyer with immigration expertise."
"I endorse Attorney Wiedemann. From his answers and time on Avvo, it is clear he is dedicated to serving those in need and his clients. It's rare that lawyers spend so much valuable time helping the community, for free, and I applaud him for doing it to such a great level. Kudos"
