Chinese Immigration to the United States, 1884-1944 - A Digital Archive
Over 250,000 people who entered the United States through San Francisco or Honolulu left records of their entry. These “investigation case files” are stored in the National Archives and Records Administration (NARA) branch at San Bruno, CA. NARA has made an index to these records—the Early Arrivals Records Search (EARS)—available on the web, in conjunction with the Bancroft Library. Since 2002, volunteers at NARA have expanded this on-line index to include the records of over 91,000 people and researchers can now save their search as an excel file. It is a helpful, free resource for doing research on immigrants and immigration history.
