Camden, New Jersey
Derek A. DeCosmo has worked in both the private and public sectors on behalf of New Jersey's immigrants. Derek has represented clients before the United States Citizenship & Immigration Service, te Administrative Appeals Office, the Federal United States District Courts, and Circuit Courts of Appeal. During his time in government, first as an aide and later as Deputy Chief of Staff to Congressman Robert E. Andrews, Derek worked to ensure the rights of immigrants in the benefits and application process.

In 2008 Derek established DeCosmo Law, a full-service Immigration Law Firm specializing in Criminal-Immigration matters. After years of practicing general Immigration Law and working on immigration issues from a public policy standpoint, Derek decided to concentrate his practice on the defense of immigrants in both removal and criminal court proceedings. When he started his firm he was the only attorney in the seven most southern counties of New Jersey concentrating in this area. In 2013 Derek joined Zucker Steinberg & Wixted to lead the firm's Immigration Law Group.  Derek's advocacy on behalf of New Jersey's immigrant communities led to his selection as Chairman for the New Jersey Chapter of the American Immigration Lawyers Association, which has over 10,000 members nationwide.
