US Records · US passport applications
Naturalized Polish immigrants did return to Europe. A United States passport application can document the trip with a photograph, birthplace, naturalization details and a statement of where the traveler planned to go and why.
Who needed a passport
Passport requirements changed over time. Many nineteenth-century travelers went abroad without one, while passports were required during parts of World War I and became generally required for overseas travel in 1941. The surviving applications are therefore valuable but never a complete list of return travelers.
What an application may contain
- Exact date and place of birth
- Current address and occupation
- Date, court and place of naturalization
- Date and port of emigration to the United States
- Physical description and signature
- Travel purpose, countries to be visited and planned departure
- A photograph on applications from late 1914 onward
The key date: March 1925
NARA holds passport applications through March 1925. Later applications remain in the custody of the Department of State and follow different access procedures. Search the NARA indexes and digitized partner collections first, then use the application number to confirm that you have the correct person.
Connect the passport to the return voyage
Use the proposed departure date to search outgoing travel and the later passenger list for the return to America. A returning citizen may list a Polish contact, an American address and the duration of the visit. Compare those details with the family story and with children who may have traveled on the same passport.
Common identification problems
- A married woman may appear under her husband’s surname
- A child may be included with a parent rather than indexed separately
- The birthplace may use the contemporary German, Russian or Austrian spelling
- A passport extension or emergency application may be filed in a separate series
A passport application proves that travel was planned and a passport was requested. Confirm that the journey happened with a passenger list or another dated record.
