One date decides whether your trip happens: your US passport has to be valid for at least six months from the day you land in Cambodia. Miss it by a week and the airline stops you in the United States, long before you reach Phnom Penh. Here is exactly how the rule is counted, where it bites, and how to plan a renewal around it.
Yes. Your US passport must be valid for at least 6 months from your date of entry into Cambodia. Validity is measured from the day you arrive, not from the day you apply for the eVisa or book your flight, so count forward from your arrival date. The rule is enforced by your airline at the US departure gate because the carrier is liable if Cambodia refuses you, which means a short-dated passport stops you at LAX, SFO, or JFK — not in Phnom Penh. There is no gate-agent discretion: a passport one week inside the window is treated as expired. Because your eVisa is tied to the exact passport number you apply with, the safe move when you are anywhere near the line is to renew first, then apply on the new book.
This guide walks through exactly how the six-month window is counted, why Cambodia uses it at all, where Americans most often miscount it, and how to fit a passport renewal around your eVisa without losing your trip. For the wider passport picture — blank pages, damage, name changes — start with our Cambodia passport requirements for Americans guide, see the full Cambodia eVisa documents required for Americans checklist, and the full Cambodia visa for United States citizens hub ties cost, documents, and timing together in one place.
The fix is an ordering rule, and it is simple: renew first, then apply on the new passport number. Never the other way around. Get the new book in hand, read off its number and expiry, and only then start the eVisa application. This is the same principle behind every field on the Cambodia visa requirements for US citizens checklist — the data you type has to match the document you travel on, exactly.
Once your passport clears the six-month count and you are applying on the right book, the eVisa is straightforward: approved in 3 business days and delivered as a printable PDF by email, with US-timezone support if anything needs a second look and free resubmission if Immigration flags a correction. You can start your Cambodia eVisa application the moment your passport is settled.
The single rule that prevents the most stressful version of this — a paid eVisa attached to a passport you cannot use, discovered at the gate — is to renew first and apply second. Validity is only one of the passport checks, so pair this with the rules on the blank passport pages needed for Cambodia and on a damaged or expiring passport with a Cambodia eVisa, and confirm your complete entry set against the Cambodia visa requirements for US citizens checklist.
Next steps and related reading for Americans: apply for your Cambodia eVisa once your passport clears the six-month count, review the full Cambodia passport requirements for Americans for the blank-page and damage rules, and run through the Cambodia eVisa documents required for Americans checklist as the single reference for cost, documents, and timing.
