What countries allowed Jewish refugees during World War 2?

During World War II, several countries permitted Jewish refugees to enter, albeit often in limited numbers. Notable examples include the United States, which implemented the Wagner-Rogers Bill to allow more Jewish children, and the United Kingdom, which facilitated the Kindertransport for unaccompanied minors. Other countries, such as Sweden, Denmark, and Switzerland, also provided refuge, though many nations had restrictive immigration policies at the time. Ultimately, the response varied widely, with some nations offering substantial assistance while others largely closed their borders.
