It's possible you're thinking of a different museum or institution. There are several museums in San Francisco that focus on immigration, including:
* The Chinese Historical Society of America: This museum tells the story of Chinese Americans in San Francisco and the United States.
* The Japanese American National Museum: While not located in San Francisco, this museum in Los Angeles tells the story of Japanese Americans in the US, including the internment during World War II.
* The Museum of the African Diaspora (MoAD): This museum explores the African Diaspora, including the history of immigration and the impact of African culture in the United States.
* The Angel Island Immigration Station: Located on Angel Island in the San Francisco Bay, this former immigration station housed thousands of immigrants from Asia, Europe, and Mexico. Visitors can explore the island and learn about the stories of those who passed through.
