Start with the records you already have
A travel history often starts as scattered evidence: a return ticket in one inbox and a passport stamp on another page. Add those records together. TravelHistoryTool reads the dates and suggests a list of trips, most recent first. It marks missing returns and conflicting dates for you to check.
Upload booking emails, boarding pass screenshots, PDFs or spreadsheets. Passport stamp reading is in beta. You can also add a CBP FOIA response or import a Google Maps Timeline export. Keep the originals open while reviewing. A flight that was booked and later cancelled must not become a completed trip in your list.
What Part 8, Item 1 asks for
Enter the date you left the United States, the date you returned and every country visited. Use mm/dd/yyyy and work backwards from the latest trip. The general provision asks for five years; other filing bases use the period in the instructions. Omit day trips completed within 24 hours. Form N-400, Part 8, Item 1
The form has three travel columns, with no day-total column. N-400 travel table Our day totals are an extra aid for checking. A trip covering several countries belongs between its U.S. departure and return dates. Check that the country list reflects your actual journey, including changes made after booking.
How days outside the United States are counted
USCIS treats both the U.S. departure date and the U.S. return date as days physically present in the United States. N-400 instructions: Physical Presence
For example, leaving on June 1 and returning on June 10 gives eight days outside: June 2 through June 9. A missing return date cannot produce a complete trip total. Check overnight flights against the date you arrived back in the United States, rather than the date your flight left another country. See our counting method.
Physical presence and continuous residence are separate rules
The usual physical-presence minimum is 30 months, or 913 days, within five years under the general provision. The qualifying U.S.-citizen spouse provision uses 18 months, or 548 days, within three years. These are days inside the United States. USCIS physical-presence requirements
An absence longer than six months but shorter than one year creates a presumption that continuous residence was broken; evidence can rebut that presumption. USCIS continuous-residence policy update An absence of one year or more generally breaks continuous residence, subject to the residence-preservation provisions described by USCIS. N-400 instructions: Continuous Residence
These rules describe different parts of the official assessment. This calculator reports the dates and totals in your records. It does not decide whether a long absence interrupted residence, whether an exception applies or when to file.
When the travel table is too short
Use Part 14 for additional information. Further sheets need your name and A-Number at the top, the relevant Page, Part and Item numbers, and your signature and date on each sheet. In edition 01/20/25, the travel reference is Page 6, Part 8, Item 1. Form N-400, Part 14
Check the edition you are using before copying that reference. Review every page of the export and complete any required identifying details yourself. Our PDF is a record-organizing document. Its layout does not mean USCIS has approved the software or accepted the document for a particular application.
Why a green card holder may not find I-94 travel history
CBP states: “No, United States Citizens and Lawful Permanent Residents cannot retrieve their travel history using the I-94/I-95 website.” CBP I-94/I-95 FAQ
Use the CBP FOIA travel history guide to find the official records-request route. Meanwhile, combine records you already hold. Do not treat an empty search result as a complete travel history, and do not invent dates to close a gap.
