The I-94 website is closed to you
“United States Citizens and Lawful Permanent Residents cannot retrieve their travel history using the I-94/I-95 website,” says CBP.
What CBP saysRebuild your N-400 travel history from your passport stamps

From passport stamps to Part 8
Keep each date next to the stamp it came from.
| Trip | Date you left | Date you returned | Countries | Days outside |
|---|---|---|---|---|
| A | 05/12/2025 | 05/20/2025 | Canada | 7 |
| B | 01/03/2025 | 01/09/2025 | Mexico | 5 |
| C | 08/14/2024 | 09/01/2024 | Japan | 17 |
Why the dates are hard to find
For green card holders, the usual records can leave gaps.
CBP’s own record takes a FOIA request
It’s free and online since January 2026, but CBP publishes no processing time. Reported waits run from weeks to many months.
How to request itNewer trips leave fewer stamps
Europe’s Entry/Exit System replaced passport stamping for most visitors on April 10, 2026. Drives into Canada or Mexico often never got one.

Photograph, check, then export your travel list.

How to find your travel history for the citizenship application
No website gives a green card holder their trips. The places your travel dates are still recorded, from passport stamps to card statements, and how to put them together.
Rebuilding your trips from passport stamps, and what to do when there are none
How to read passport stamps into trips for the N-400, and what to do for land crossings, Europe after April 2026 and U.S. trips without a stamp.
Don’t remember your exact travel dates for the N-400?
USCIS publishes no rule on approximate dates. What the form says, what legal-aid practitioners advise, and how to narrow a date down first.
N-400 days outside the U.S.: the 913-day, 6-month and 1-year rules
Physical presence (913 or 548 days) and continuous residence (6 months, 1 year), each with its own way of counting days, quoted from the USCIS Policy Manual.
Questions
About the waitlist, your documents, and your travel draft.
When does TripRebuild open?
We’re opening to the waitlist first. Leave your email and we’ll write once when it’s ready. We won’t send anything else.
How will it work?
You upload photos of your passport stamp pages. Each photo is sent to our server once, read by an AI vision model into dated entries and exits, and discarded. The readings are paired into trips you can edit, and you confirm each trip against its stamp before exporting.
Are my documents stored anywhere?
No. Stamp photos are never written to storage; they are discarded as soon as the reading comes back. Your draft timeline is saved only in your own browser.
Will it find every trip I took?
No tool can promise that. It reads what your stamps show. Faded stamps and unstamped land crossings won’t appear, so you check every row against your own records and add what’s missing.
How are days counted?
The USCIS way: the day you leave and the day you return count as days in the United States. Leaving January 1 and returning January 10 is 8 days outside. Source: USCIS Policy Manual, Volume 12, Part D, Chapter 4.
Is this legal advice?
No. TripRebuild is a drafting aid, not legal advice, and it isn’t affiliated with USCIS or CBP. You are responsible for what you file. If a trip may have lasted more than 6 months, talk to an immigration attorney.
