He has represented multinational consulting firms in Department of Labor Wage and Hour investigations and managed large-scale PERM labor certification programs for major green card sponsors.

David earned his J.D. from Notre Dame Law School, where he received the Jessup International Moot Court Award, and his B.A. in English from Wake Forest University. He is a member of the American Immigration Lawyers Association and is admitted to practice in Illinois.
