封面撕裂、覆膜褪色或有效期不足六个月都可能让你的柬埔寨之行在出发前就泡汤——问题出在美国机场,而不是金边边境。解决方法很简单但顺序很重要:先更新护照,然后再用新护照申请电子签。

No — fix the passport first. A US passport with torn pages, water damage, a peeling bio-page laminate, or a punched corner can be treated as invalid, and one with less than 6 months of validity from your date of entry can get you turned away at the US gate before you ever reach Cambodia. Because the Cambodia eVisa is locked to one exact passport number, the safe sequence is always the same: renew or replace the passport first, wait for the new book, then apply for the eVisa using the new passport details. Apply on a damaged or expiring book and you risk paying for a visa you cannot use.
So the question is never "can I apply with this passport?" It is "should I renew first?" This guide covers when a worn passport crosses the line into refused, how the 6-month validity rule actually bites at the gate, and the exact safe order to renew then apply. If your book is in good shape and just needs a sanity check, our Cambodia passport requirements for Americans lays out the full standard. When you are ready and your passport is sorted, you can apply in a few minutes.

This catches more US travelers than damage does, because an expiry date in the future feels safe right up until you do the subtraction. If you are anywhere close to the line, treat it as a renew-first situation. Our full breakdown of the US passport validity 6-month rule for Cambodia walks through more dates and edge cases, and the broader Cambodia passport requirements for Americans covers blank pages and condition alongside validity.

Do not try to overlap the steps to save a few days. We have seen travelers apply on the old book hoping the new passport will "probably be fine," then have to pay for a second eVisa once the number changes. The eVisa fee is not refundable against a passport-number mismatch you created. If you want to see exactly what the application asks for once your new book is in hand, our Cambodia eVisa documents required for Americans lists every field and upload.

For a documented life-or-death emergency — a death or grave illness in your immediate family — there is a separate, faster path through a State Department passport agency or, if you are already overseas, the nearest US embassy or consulate. If you are in the region and your passport is lost, stolen, or destroyed right before a Cambodia trip, the US Embassy in Phnom Penh can issue an emergency replacement; check the State Department travel page for Cambodia for current contact details and the exact documents to bring. Our guide on whether you can be denied entry to Cambodia covers what happens at the border if you arrive on a marginal document.

Pull your passport out before you do anything else. Check three things: the expiry date against your planned entry date with the full 6 months in mind, the condition of the bio page and laminate, and whether you have at least one clean blank page for the entry stamp. If all three pass, you are clear to apply today. If any one of them fails, the passport is the first job and the eVisa waits.
Get the order right and the rest is fast. Renew or replace the book, wait for it to arrive, then apply for the Cambodia eVisa on the new details — Tourist $80 USD, Business $90 USD, approved in 3 business days, delivered as a printable PDF by email, with free resubmission if Immigration flags a correction and US-timezone support if anything looks off. The Cambodia eVisa documents required for Americans guide is the checklist to run once your new passport is in hand.
