Who was sent to angel island and under what circumstances?

Angel Island, located in San Francisco Bay, served primarily as an Immigration station from 1910 to 1940. It was used to detain Asian immigrants, particularly Chinese, who were subjected to the Chinese Exclusion Act of 1882, which severely restricted immigration from China. Many were sent there for questioning and processing, facing long waits and harsh conditions. The station also detained other groups, including Japanese and South Asian immigrants, under similar restrictive immigration policies.
