Tanya Hanna counsels clients on a broad range of regulatory compliance and enforcement matters, including in the areas of US economic sanctions laws and regulations and export controls administered by the US Department of the Treasury's Office of Foreign Assets Control (OFAC); US Department of Commerce's Bureau of Industry and Security (BIS); and the US Department of State.

Tanya focuses specifically on providing economic sanctions compliance advice to clients engaged in complex transactions, including with respect to comprehensive US primary and secondary sanctions targeting Iran, Syria, Sudan, Cuba, North Korea, and the Crimea region of Ukraine, as well as US sectoral sanctions targeting Russia and US antiboycott regulations. She also conducts sanctions and export control-related internal investigations and assists clients with preparing voluntary self-disclosures of apparent violations. She also represents clients in administrative proceedings before OFAC and BIS, as well as in relation to Freedom of Information Act (FOIA) requests and appeals.

In addition to economic sanctions and export controls, Tanya works on complex litigation matters representing foreign sovereigns under the Foreign Sovereign Immunities Act (FSIA) and advises clients in national security reviews before the Committee on Foreign Investment in the United States (CFIUS).

Prior to joining White & Case, Tanya worked as a defense consultant for the US government, specializing in counterterrorism. Ms. Hanna also served as pro bono fellow for the American Immigration Lawyers Association (AILA), where she specialized in immigration matters.
