What significant act was passed in 1948 to assist WWII refugees in the U.S.?

The Displaced Persons Act of 1948 was a significant piece of legislation aimed at providing assistance and a pathway to permanent residency for refugees who were displaced as a result of World War II. This act allowed for the admission of individuals who had been forced to flee their homes due to the war, thereby responding to the humanitarian crisis that the post-war period presented.

The legislation was pivotal because it marked one of the first efforts by the United States to establish a formal process for admitting refugees, reflecting a recognition of the unique circumstances faced by those who were uprooted by the conflict. It allowed for up to 200,000 displaced persons from Europe to resettle in the United States, which was an important step in addressing the needs of those who had suffered due to war and persecution.

This act set a precedent for future refugee policies and highlighted America's growing role in international humanitarian efforts after the war. While other acts mentioned in the choices, like the Refugee Relief Act and the Immigration and Nationality Act, addressed related issues, it was the Displaced Persons Act specifically focused on WWII refugees at that time, making it the most relevant and significant piece of legislation for this context.
