The Displaced Persons Act 1948
On June 25, 1948, Harry S. Truman marked the Displaced Persons Act of 1948. In its most fundamental sense, the demonstration would aid the resettlement of thousands of European outcasts (to a great extent through allowing American visas) who had been dislodged from their nations of origin because of World War II.
While the demonstration at the same time offered help to evacuees, it put severe cutoff points on the quantity of individuals who could enter the U.S. by considering any individual ineligible for an American visa who had entered an exile camp after December 22, 1945. This apparently erratic limitation really disallowed the entry of Jewish outcasts who endure the Holocaust, however when confronted with slaughters in post bellum Poland, escaped to local Germany after December 22.
