Ellis Island was a designated federal immigration station located in New York Harbor, which served as the gateway for millions of immigrants entering the United States from 1892 to 1954. Angel Island was a federal immigration station located in San Francisco Bay, which served as the entry point for Chinese immigrants from 1910 to 1940.
The primary difference between the two immigration stations is the population they served. Ellis Island was open to all immigrants who were approved by the US government, while Angel Island was only open to Chinese immigrants. Additionally, Ellis Island immigrants were often processed more quickly than those at Angel Island, which could take weeks or months.
