Form N-400 requires you to report travel outside the United States during the period relevant to your naturalization application. If you travel frequently or did not keep a travel log, reconstructing the dates can take some work.
Do not rely on a single source. Build the best record you can by comparing government records with your own documents.
Start With Government Travel Records
CBP allows people to request their own international arrival and departure records through FOIA, and CBP specifically identifies entry and exit records used for LPR or citizenship purposes as an appropriate FOIA request. CBP also warns that travel records may be incomplete for lawful permanent residents, particularly for car travel between the United States and Canada or Mexico.
The online I-94 travel-history tool can also be useful when it contains your records, but it was designed principally for nonimmigrant traveler records. An N-400 applicant should not assume the online history is a complete LPR travel record.
Check Passports and Transportation Records
Review current and expired passports for entry and exit stamps. Then check airline accounts, old reservations, electronic tickets, boarding passes, train or ferry records, rental-car records, and toll records. Land crossings are especially important because they are easier to miss in electronic travel histories.
Use Your Digital Records to Fill the Gaps
Email, calendars, bank and credit-card statements, hotel reservations, photographs, and retained phone-location history can help confirm dates. Search for airline names, destination cities, “boarding pass,” “reservation,” “hotel,” and similar terms.
Work calendars, school records, conference registrations, receipts, and family messages can also help when a trip does not appear anywhere else.
Build One Master List
Create a spreadsheet with departure date, return date, destination, and the record supporting each date. When two sources conflict, investigate the difference instead of silently choosing the date that seems most convenient.
No single government database is guaranteed to contain every trip. USCIS evaluates physical presence and continuous residence using the application, available records, and the applicant’s testimony. The goal is a truthful reconstruction supported by the best evidence available.
Pay Extra Attention to Long or Frequent Trips
Travel history is not just clerical. Absences of more than six months can raise continuous-residence issues, and physical presence is a separate naturalization requirement. If you had a trip around six months or longer, repeated extended travel, or uncertainty about whether you meet the residence requirements, analyze that issue before filing.
