Anne Seymour is Of Counsel in Wilson Sonsini Goodrich & Rosati's Washington, D.C., office, where she focuses on issues related to compliance and enforcement of U.S. export control regulations and economic sanctions and U.S. import regulations.

Anne counsels foreign and domestic clients across technology industries on all aspects of international trade, including export controls, economic sanctions, and import issues. This work includes providing advice on potential export and import considerations stemming from cross-border technology transfers, joint venture projects, mergers and acquisitions, foreign investment, foreign distributor agreements, and delivery (both physical and virtual) of products and services. 

Anne is an expert in commercial and dual-use controls promulgated under the Export Administration Regulations, military-specific controls administered under the International Traffic in Arms Regulations, and economic sanctions programs implemented by the Office of Foreign Assets Control. Anne works closely with companies to determine which regulations may affect their transactions; obtain necessary government approvals related to the import, export, or transfer of their products, software, technology, and services; design and implement internal compliance programs; conduct compliance assessments; train employees on regulatory compliance issues; and, when necessary, conduct internal investigations and prepare voluntary disclosures.

Anne assists clients as new regulatory challenges arise, including adapting to new sanctions regimes, classification of “critical technologies” as they may apply to CFIUS analyses, and obtaining of “deemed export” licenses for clients that employ visa holders in export-controlled areas. She also assists clients with import-related matters, such as evaluating supply chains, responding to CBP inquiries and actions, duty assessment, Harmonized Tariff Schedule classification, country of origin determination, and valuation.
