IGO Anti-Boycott Act This bill expands an existing anti-boycott law to include certain boycotts imposed by international governmental organizations (IGOs). Current law prohibits various actions by U.S. persons (individuals or entities) in relation to boycotts imposed by foreign governments on a country which is friendly to the United States and that is not itself the object of a U.S. boycott. This bill applies those prohibitions to similar boycotts imposed by IGOs. Prohibited actions include (1) refusing to do business with companies organized under the laws of the boycotted country, if the refusal is pursuant to an agreement with or request from the country or IGO imposing the boycott; (2) refusing to employ any U.S. person on the basis of race, religion, sex or national origin; and (3) furnishing information about whether someone is associated with charitable or fraternal organizations that support the boycotted country. The bill also requires the President to annually submit to Congress and make available to the public a report describing these boycotts and listing the foreign countries and international organizations involved in fostering or imposing them.
