Augustine counsels clients on U.S. sanctions and export controls, customs compliance, and international trade regulation.

Augustine is an associate in Dorsey’s Seattle office who assists clients with U.S. export control matters under the International Traffic in Arms Regulations (ITAR) and the Export Administration Regulations (EAR) and the various sanctions programs administered by the Office of Foreign Assets Control (OFAC). He has also worked extensively on government enforcement actions, U.S. customs compliance matters, and commercial litigation matters.

He previously worked on customs enforcement matters for the Office of Chief Counsel of U.S. Customs and Border Protection (CBP), a federal agency in the U.S. Department of Homeland Security (DHS). Augustine served successively as a judicial clerk to two federal district judges in the U.S. District Court in Puerto Rico, and he has worked in the chambers of a federal judge at the U.S. Court of International Trade.
