The 1953 flood disaster in the Netherlands resulted in the US Refugee Relief Act including a slot for 15,000 ethnic Dutch who had at least 50% European blood (one year later loosened to Dutch citizens with at least two Dutch grandparents) and a clean legal and political record. In 1954, only 187 visas were actually granted. Partly influenced by the anti-western rhetoric and policies of the Sukarno administration, anti-communist US Representative Francis E. Walter pleaded for a second term of the Refugee Relief Act in 1957 and an additional slot of 15,000 visas in 1958.
