Foley Hoag, recognized around the world for its expertise in Public International Law and representation of sovereign States, has established a special practice group catering to States' Permanent Missions to the United Nations. The firm's United Nations practice group provides legal advice and representation to Permanent Missions to the United Nations on matters before the Security Council, General Assembly, Sixth Committee (Legal Affairs), United Nations Commission on International Trade Law (UNCITRAL) and meetings of the States Parties to the Law of the Sea Convention, inter alia.

The group is led by chair Christina Hioureas, who, before joining the firm, served as Special Legal Adviser to the Republic of Cyprus and represented that State on the Sixth Committee (Legal Affairs).

Foley Hoag's United Nations practice group is supported by the firm's International Litigation and Arbitration Department, which includes more than 30 highly experienced international litigators - based in New York, Washington, Boston and Paris - who represent States regularly before the International Court of Justice, the International Tribunal for the Law of the Sea, and international arbitral forums such as the Permanent Court of Arbitration, the International Centre for the Settlement of Investment Disputes and the International Chamber of Commerce.
