Angel Island (Immigration and Multiculturalism)Angel Island is located in the San Francisco Bay on the west coast of the United States. At various times from about 1863 to 1910, Angel Island was used for such functions as discharge depot, infantry garrison, and military camp. Beginning in 1910, Angel Island became the headquarters of the Angel Island Immigration Station, which processed about 175,000 Asian immigrants entering into the United States from China and then later from other countries such as the Philippines, Korea, and Japan.
