I focus my practice on immigration and citizenship law and have handled every type of immigration case, from family immigration matters to business and investor cases and citizenship applications. I am a nationally known expert on immigration and national security laws, and have testified regularly before Congressional committees on immigration, homeland security, and military matters. As a retired Lieutenant Colonel in the Military Police, U.S. Army Reserve, I have extensive experience with U.S. military issues. I have also worked as a professor at the United States Military Academy at West Point, and have served as an adjunct instructor at the University of Alaska. I was a member of the American Bar Association Commission on Immigration from 2008-2012. I regularly author articles on military-related immigration issues, and am well-versed on “parole in place” for military family members and the Military Accessions Vital to the National Interest (“MAVNI”) Program. I authored the book Immigration Law & the Military, which was published by the American Immigration Lawyers Association in 2012. On September 25, 2013, I was named a 2013 MacArthur Fellow by the John D. & Catherine T. MacArthur Foundation.
