Your Cambodia eVisa works at three international airports and a short list of land and sea crossings in 2026 — but not at every border you might assume. Here is exactly where it is accepted, what changed this year, and the closures that catch Americans out.

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.

All seven Thailand–Cambodia land borders have been closed since June 2025, so in 2026 the only way for Americans to get from Thailand into Cambodia is to fly. Here is how the Bangkok-to-Siem Reap and Bangkok-to-Phnom Penh routes work, the Cambodia eVisa you need before you board, and why the old Poipet overland plan no longer exists.
Three ways to cover the 195 miles between Cambodia’s capital and Angkor Wat: a $15 express bus, a 45-minute flight, or a slow river ferry. Here is what each one actually costs an American traveler, how long it takes, and which one fits your trip.
