CM/1 applications were handed out even before the IRO officially existed, when the Preparatory Commission of the International Refugee Organization (PCIRO) was still in operation. In July 1947, the PCIRO began handling responsibilities that would be taken over by the IRO in August 1948. For this reason, some CM/1 applications have “Application for PCIRO Assistance” printed at the top. They are the same document type, however.
