Migration from Asia to the US 1820-1957, by region
After this law came into effect, migration from Asia was quite low until the end of the nineteenth century. As the twentieth century began, migration from Asia to the US increased gradually, particularly from Japan and Turkey, although overall migration decreased again following the First World War and the Great Depression. In the lead up to the Second World War, migration to the US decreased greatly, particularly from Japan, who were one of America's enemies during the war. As the Chinese Civil War ended in the late 1940s, the US accepted a few thousand Chinese asylum seekers, and then migration from Asia grew to it's pre-Depression levels in the 1950s.
