Immigration records

Ship lists and naturalization.

5 min read

Immigration records can tell you where an ancestor came from, the key to research in another country.

Records to look for

  • Passenger arrival lists, which become more detailed after 1906
  • Naturalization records: declarations of intention and petitions
  • Census answers about year of immigration and citizenship
  • Passport applications

Where to look

Try the National Archives, FamilySearch, the free Ellis Island passenger search and the USCIS Genealogy Program for some 20th-century files.
