美国公民柬埔寨护照要求：有效期和空白页详解
两个数字决定您的美国护照是否可用于前往柬埔寨：自抵达之日起六个月的有效期，以及一页完整的空白页。任何一项出错，航空公司都会在美国阻止您，您根本到不了金边。
What are the passport requirements for US citizens entering Cambodia?
Your US passport must be valid for at least 6 months from your date of entry into Cambodia and must have at least one full blank page for the entry stamp. Validity is counted from the day you arrive, not the day you apply for the eVisa, and the 6-month rule is enforced by the airline at your US departure gate. The eVisa is tied to the exact passport number on your application, so if your passport is expiring soon or short on pages, renew it first and then apply on the new book. Damaged passports and recently changed names are the two edge cases that catch Americans out most often.
要点总结
- Your US passport must be valid for at least 6 months from your date of entry into Cambodia — counted from arrival, not from the day you apply.
- You need at least one full blank passport page for the Cambodian entry stamp; frequent travelers should count their clean pages before applying.
- The 6-month rule is enforced by the airline at your US departure gate, so a short-dated passport stops you at LAX, SFO, or JFK — not in Cambodia.
- Your eVisa is tied to the exact passport number you apply with; renew first if your passport is close to the line, then apply on the new book.
- Standard US passport renewal runs about 4 to 6 weeks in 2026, with expedited service roughly 2 to 3 weeks — plan the renewal before the eVisa.
The two passport rules that actually decide your trip
This guide covers exactly how the 6-month window is counted, how many blank pages you really need, what happens if your passport is damaged or recently renamed, and how renewal timing fits around your eVisa. For the bigger picture on whether you need a visa at all, start with our overview of whether US citizens need a visa for Cambodia, then come back here for the passport specifics. The full Cambodia visa for United States citizens hub ties the cost, documents, and timing together in one place.
The 6-month validity rule, counted correctly
If your passport is sitting right on the edge of the window, do not gamble on a sympathetic gate agent — there is no discretion built into the system. Renew first. We break the timing down in detail in our guide to the US passport 6-month rule for Cambodia, and the broader Cambodia visa requirements for US citizens checklist shows how the passport rule sits alongside the other entry conditions.
Blank pages — how many you actually need
A quick reality check on the standard US passport: the regular book has 28 pages, of which around 17 are usable visa pages once you set aside the cover, signature, and endorsement pages. The 52-page book — what the State Department now issues by default in many cases, and which you can request at no extra cost — gives you far more runway. If you travel often and you are renewing anyway, opt for the larger book and you will not think about pages again for years. To see how the blank-page rule sits alongside everything else you need, the Cambodia visa requirements for US citizens checklist walks through exactly what counts as a clean page.
Damaged passports, name changes, and the eVisa match
常见问题解答
How long must my US passport be valid to enter Cambodia?
At least 6 months from your date of entry into Cambodia. Count it forward from your arrival date, not from the day you apply for the eVisa. If you arrive on March 1, your passport must be valid through at least September 1. An expiry that lands inside that six-month window is treated as expired for this trip, and the airline will stop you at your US departure gate.
How many blank passport pages do I need for Cambodia?
At least one full blank page for the entry stamp. Cambodian Immigration stamps a clean page, so a page already half-used by another country counts as used. Flip through your visa pages before you apply and confirm you have at least one genuinely clean page. If your book is full, you need a passport renewal — the State Department no longer adds visa-page inserts to US passports.
Is the 6-month rule checked in Cambodia or in the United States?
It is enforced by your airline at the US departure gate, because the carrier is liable if Cambodia refuses you on arrival. That means a short-dated passport stops you at LAX, SFO, or JFK — not at Phnom Penh. There is no discretion in the gate system, so do not count on a sympathetic agent if your passport is close to the line.
Can I enter Cambodia with a damaged US passport?
Normal wear is fine, but significant damage — water damage, a detached cover, a delaminated photo page, or a scuffed machine-readable zone — can get you refused by either your airline or Cambodian Immigration, even if the dates and pages check out. A damaged passport is treated as invalid, not as a lesser form of valid. If yours is in poor shape, renew before you apply for the eVisa.
My name changed after marriage — which name do I use on the eVisa?
Use the exact name on your current passport. If your passport still shows your maiden name, apply in your maiden name. If you have already updated your passport, apply in your new name and travel on the new book. The eVisa is matched against your passport, not your driver license, so the two names must agree character for character.
Should I renew my passport before or after applying for the eVisa?
Before. Your eVisa attaches to the exact passport number you submit, and a renewed passport carries a new number. If you renew after applying, the eVisa is tied to a book you no longer hold, and that mismatch can stop you at the gate. Renew first, receive the new passport, then apply on the new details.
