By the expiration date of our present displacedpersons law. June 30. 1950. there will remain only a few thousand such wardisplaced persons in central Europe. other than the socalled hard core who because of social or physical disqualifications are ineligible for resettlement. The constitution of the International Refugee Organization. however. embraces not only displaced persons who were displaced by the war in central Europe. but. in addition. it embraces all persons in the entire world who are. or who may hereafter be out of their country of nationality or former residence and who are unwilling to return. Some year or two after the war in central Europe there began and continues until the present time. a general migration from eastern Europe into the occupied areas of western Europe of hundreds of thousands of persons. who. because of political and economic turmoil. have been leaving their homelands. The potential number of persons embraced in this second category has been estimated to be in millions.
