In addition, Brooklynn advises clients on compliance with economic sanctions programs administered by the Office of Foreign Assets Control (OFAC), export controls administered under the Export Administration Regulations (EAR) and the International Traffic in Arms Regulations (ITAR), and tariff actions involving U.S. agencies such as the United States Trade Representative (USTR). Her work includes providing day to day compliance advice and due diligence, developing trade compliance programs, conducting internal investigations, and representing clients before U.S. government agencies to help deliver tailored solutions and ensure companies operate smoothly within complex regulatory frameworks.
