An estimated 3,000 highly educated Ukrainians, many from the third wave, left Argentina for the United States or Canada in the 1950s due to greater economic opportunities. Another 3,000 Ukrainians left Argentina for the Soviet Union during the late 1950s, after having been promised a "prosperous life in the homeland." Only a third of the latter group were able to return to Argentina. These demographic losses were compensated for by small numbers of Ukrainians moving to Argentina from Paraguay and Uruguay.
