Answer: see below
Step-by-step explanation:
The United States' response to the Holocaust before, during, and after World War II was complicated.
Prior to World War II, the U.S. had been resettling Jewish refugees since the 1880s. In 1939, Congress passed the Johnson-Reed Immigration Act to limit immigration from Eastern Europe. This legislation was designed to keep Jews from entering the country by making it harder for them to get visas and creating quotas based on national origin.
During World War II, the U.S. government tried to prevent Jews from being deported by issuing visas for refugees and providing them with temporary safe haven in camps such as Gurs in France and Shanghai in China. However, these efforts were limited by lack of resources and political will.
After World War II ended in 1945, President Harry S Truman signed an executive order establishing a new immigration policy that allowed displaced persons (DPs) who had been displaced by war or persecution to enter the United States permanently if they could prove they were victims of Nazi persecution or discrimination against other groups such as Roma (Gypsies) or homosexuals.
