What was the effect, after WWI, from the other countries, after we had deferred some of their immigrants?

Many countries were experiencing mass emigration to the U.S. for numerous reasons but mostly it was from "economic pressure, political unrest and war weariness"(Historical Newspapers), that so many immigrants were accepted and allowed to gain citizenship. The war had caused problems all through out Europe and it fit in with the new need for fresh labor. The unaffected United States created a safe haven which allowed immigrants to escape the fear of war and threat of more violence. Their was no call for restriction, by the nativists, on the immigration yet and it made the U.S. a more liked place for foreigners. Their was no tensions or hostilities from other governments and countries as their became more emigration to the U.S., this allowed previous thoughts on the U.S.(disapproval of joining the Allied effort late) to dissipate.
