Which Cambodia Entry Points Accept Your eVisa? 2026 Airport and Border Guide for Americans

Land and sea crossings — where the eVisa works overland

The eVisa is not airport-only. Cambodia publishes a list of designated land and water crossings where an electronic visa is accepted, and they cover the routes most overland travelers actually use — provided you are not coming from Thailand (more on that next). The two that matter most for Americans on an Indochina loop are the Vietnam and Laos borders.

• Vietnam land borders: the major crossings used by Mekong-route travelers — including the Bavet crossing on the Ho Chi Minh City road and the Kaam Samnor river crossing on the Mekong fast-boat route — accept the eVisa. This is the classic Saigon-to-Phnom Penh overland or river leg, and it works on an eVisa in 2026.
• Laos land border: the Trapeang Kriel crossing in the north, the standard route down from southern Laos and the 4,000 Islands, accepts the eVisa.
• River and sea ports: the main Mekong river ports and the coastal sea ports are on the eVisa-eligible list, which matters if you are arriving by cruise or river boat rather than by air.

The honest caveat: the eVisa-eligible crossing list is specific, and a small regional crossing your map shows may not be on it even when a nearby major one is. The carrier or boat operator will not always know the rule. If your plan depends on entering at a particular land border rather than flying, confirm that exact crossing is eVisa-eligible before you commit — the safe default for any American who is unsure is to fly into KTI, SAI, or KOS, where acceptance is never in question. Our full breakdown of which airport or port of entry to choose walks through each option in more detail.

The Thailand land border is closed — what that means for your route

This is the single most important fact for any American planning a Thailand-and-Cambodia trip in 2026: all seven Thailand-Cambodia land borders have been closed since June 2025. That includes the crossings travelers have leaned on for years — Poipet on the Bangkok-to-Siem Reap road, Cham Yeam near the coast, and the rest. You cannot use a Cambodia eVisa to walk or drive across from Thailand right now, because the border itself is shut, not because the eVisa fails to cover it.

The old backpacker dream — Bangkok by train, then a minibus across at Poipet into Siem Reap — does not run in 2026. If your itinerary pairs the two countries, you connect them by air. Bangkok to Siem Reap, Bangkok to Phnom Penh, and Bangkok to Sihanoukville are all short, frequent flights, and your eVisa is accepted the moment you land at the Cambodian airport. The closure does not affect your visa at all; it only removes the overland option between these two specific countries.

This situation has been static for a year and there is no confirmed reopening date, so plan around flying rather than waiting for the land border to reopen mid-trip. Vietnam and Laos crossings remain open and eVisa-eligible, so the broader Indochina loop is still very much doable overland — it is specifically the Thailand land legs that are off the table. We keep a running update on the Thailand-Cambodia land border situation for Americans if you want the current status before you book.

What actually happens when you arrive

Knowing where your eVisa works is half the picture; the other half is the walk through arrivals itself. The routine is the same at all three airports, and once you have done it once it is genuinely fast. Here is the sequence I see Americans move through at the gate.

First, have your eVisa printed. The document arrives in your inbox as a PDF, and while officers can sometimes read it off a phone screen, a printed copy is what they expect and what keeps the line moving — a dead phone battery at the desk is a problem you do not want. Carry the printout in your passport. Second, have your e-Arrival Card done. This is the separate pre-arrival form, and at KTI and SAI it is checked at or right beside the immigration desk. Travelers who skipped it get pulled aside to complete it on the spot, which is the most common slow-down I log.

At the desk, you join the eVisa lane, hand over your passport with the printed visa, and the officer matches your face to the document, stamps you in, and you are through. The eVisa is single-entry, so the stamp starts your 30-day stay; the visa itself stays valid for three months from its issue date, which is the window you have to actually arrive. Once you are stamped in, you collect your bag and head out — at KTI, remember the ride downtown is the long one, so line up transport in advance.

One detail Americans regularly ask about at the desk: how long the stay actually runs and whether it can be stretched. The eVisa gives you 30 days from entry on a single-entry basis, and the old tourist auto-extension ended in November 2025, so there is no longer an automatic top-up at the airport. Our guide on how long US citizens can stay in Cambodia covers the current rules in full, and the entry requirements for US citizens lays out the passport and document side before you travel.

Putting your route together

The clean version, for any American planning a 2026 trip: your eVisa works at three airports — KTI, SAI, and KOS — plus the designated Vietnam and Laos land crossings and the main river and sea ports. It does not work across the Thailand land border, because that border is closed. If you are flying, you are covered no matter which of the three airports you pick. If you are coming overland, fly the Thailand leg and cross by land only from Vietnam or Laos at a confirmed eVisa-eligible point.
