In 1949, the Federal Bureau of Investigation investigated the ZOA under the 1938 Foreign Agents Registration Act after the organization solicited supporters to accelerate technology transfers to Jews in Palestine. On February 25, 1948, the ZOA was ordered to register as a foreign agent. After a series of conferences with the US Attorney General, the ZOA changed its constitution and "affected a change in the constitution of the World Zionist Organization in an effort to remove itself from agency status. As a result, all attempts to procure the registration of the subject organization were dropped."
