The 1953 flood disaster in the Netherlands resulted in the Refugee Relief Act including a slot for 15,000 ethnic Dutch that had at least 50% European blood (one year later loosened to Dutch citizens with at least two Dutch grandparents) and an immaculate legal and political track record. In 1954 only 187 visas were actually granted. Partly influenced by the anti-Western rhetoric and policies of the Sukarno administration the anti-communist senator 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.
