カンボジアの入国口岸でeVisaはどこで使えますか？2026年アメリカ人向け空港・国境ガイド
カンボジアのeVisaは、2026年に3つの国際空港と限定された汽車・海上入国口岸で使用できます—しかし、あなたが思っているすべての国境で使えるわけではありません。在这里为您详细介绍eVisa的有效入境口岸、本年度的变化，以及让美国人困惑的口岸关闭情况。
Which Cambodia entry points accept the eVisa for US citizens?
Your Cambodia eVisa is accepted at three international airports — Techo International near Phnom Penh (KTI), Siem Reap-Angkor International (SAI), and Sihanouk International (KOS) — plus the designated land crossings with Vietnam and Laos and the main river and sea ports. It is NOT usable at any Thailand land border, because all seven Thai crossings have been closed since June 2025. For almost every American, the simplest answer is to fly: book into KTI, SAI, or KOS, carry your printed eVisa PDF, and file your e-Arrival Card in the week before departure. The eVisa itself is a single-entry document valid for three months from issue, good for a 30-day stay.
主なポイント
- Your Cambodia eVisa is accepted at three international airports: Techo International near Phnom Penh (KTI), Siem Reap-Angkor (SAI), and Sihanouk International (KOS).
- KTI (Techo International) replaced the old Phnom Penh airport on September 9, 2025 — if your booking still says PNH, your flight has already moved to the new field.
- All seven Thailand-Cambodia land borders have been closed since June 2025, so an eVisa cannot be used to cross from Thailand by land in 2026.
- The eVisa is also valid at the main Vietnam and Laos land crossings and at the major river and sea ports — but always confirm your specific crossing before you build a route around it.
- カンボジアeアライバルカードは、すべての航空による入国者にとって別途で義務付けられている手続きです - 14項目、$20 USD（当方で確認）、搭乗日の7日前までに提出してください。
Why your point of entry matters more in 2026
A Cambodia eVisa is not a universal key to every border on the map. It is accepted at a specific, published list of entry points, and in 2026 that list looks different from the one most US travelers find in older guides. Two things changed: the Phnom Penh airport moved to an entirely new field in September 2025, and the entire Thailand land border has been closed since the previous summer. Build a route around an outdated map and you can find yourself standing at a crossing your visa does not cover.
For the overwhelming majority of Americans, this is a non-issue — you fly into one of three international airports, hand over a printed PDF, and clear immigration in minutes. The complications only appear when you try to enter overland, especially from Thailand, or when your flight booking still references the old airport code. This guide lays out every entry point your eVisa actually works at this year, the ones it does not, and the small details that decide whether you walk straight through or get turned back at the desk.
I head the Cambodia Airports & Arrivals desk here, and I have logged the process at every port since the new field opened. We will start with the airports, move to the land and sea crossings, cover the Thailand closure in full, and finish with the practical entry routine. When you are ready, you can apply and have your eVisa as a printable PDF before you book a thing. For the full picture of the Cambodia visa for US citizens, our main guide pulls every piece together, and if you are still deciding whether you even need one, our guide on whether US citizens need a visa for Cambodia answers that first.
The three international airports that accept your eVisa
If you fly into Cambodia, you will land at one of three international airports, and all three accept the eVisa for arriving Americans. Pick the one closest to where your trip actually starts — there is no advantage to routing through Phnom Penh if your first stop is Angkor Wat.
テチョ国際空港（KTI）——プノンペン
This is the big one, and the one most likely to trip up a US traveler in 2026. Techo International Airport, code KTI, opened on September 9, 2025 and completely replaced the old Phnom Penh International (the field you may still see written as PNH). It sits about 20 kilometers south of the city center, so the taxi ride downtown is longer than it used to be — budget 45 minutes to an hour in traffic. Your eVisa is accepted here, and the arrivals flow is built around electronic visas: you join the eVisa lane, present your printed PDF and passport, and your e-Arrival Card is checked at the same desk.
The practical warning: if your airline ticket, your hotel transfer voucher, or an old travel blog still says "PNH," that is the retired airport. Flights have all moved to KTI. Nothing on your eVisa needs to change — the document is tied to your passport, not to a terminal — but make sure your ground transport is heading to the new field, not the old one.
よくある質問
Which airports in Cambodia accept the eVisa for US citizens?
Three international airports: Techo International near Phnom Penh (KTI), Siem Reap-Angkor International (SAI), and Sihanouk International (KOS). All three accept the eVisa on arrival for American passport holders. KTI replaced the old Phnom Penh airport (PNH) on September 9, 2025, so if your booking still shows PNH, your flight has already moved to the new field.
タイへの陆地国境を越えるためにカンボジアeVisaを使用できますか？
No. All seven Thailand-Cambodia land borders have been closed since June 2025, so you cannot cross overland from Thailand on any visa right now — including the Poipet crossing on the Bangkok-to-Siem Reap road. If your trip pairs Thailand and Cambodia, fly the leg: Bangkok to Siem Reap, Phnom Penh, or Sihanoukville are all short flights, and your eVisa is accepted the moment you land.
Does my eVisa work at the Vietnam and Laos land borders?
Yes, at the designated crossings. The main Vietnam crossings — including Bavet on the Ho Chi Minh City road and Kaam Samnor on the Mekong river route — are eVisa-eligible, as is the Trapeang Kriel crossing coming down from southern Laos. Smaller regional crossings may not be on the eligible list, so confirm your specific border before you build a route around it.
What is KTI and why is my flight no longer going to PNH?
KTI is Techo International Airport, the new Phnom Penh airport that opened on September 9, 2025 and fully replaced the old Phnom Penh International (PNH). All flights have moved to KTI. Your eVisa does not need to change — it is tied to your passport, not the terminal — but make sure your ground transport is heading to the new field, which sits about 20 kilometers south of the city center.
Do I need anything besides my eVisa to enter at the airport?
Yes — the e-Arrival Card. It is a separate, mandatory form for every air arrival, with 14 fields, submitted within 7 days before you fly. At KTI and SAI it is checked at or beside the immigration desk, and travelers who skipped it get pulled aside to complete it on the spot. Carry a printed copy of your eVisa PDF as well, since that is what officers expect at the desk.
カンボジアeVisaは1回入国土ませんか複数入国ですか？
The eVisa is single entry. It is valid for three months from its issue date — that is the window you have to arrive — and it gives you a 30-day stay once you are stamped in. If you leave Cambodia and want to return, you need a new visa. The tourist auto-extension that used to top up your stay at the airport ended in November 2025.
