Thai passport holders can enter Cambodia without a visa for stays up to 14 days. This applies in 2026 for tourism, business visits, or transit. Just show up at the border with a valid passport and an onward ticket.
Entry requirements
| Requirement | Details | Status |
|---|---|---|
| Valid passport Must be valid for at least 6 months beyond your departure date from Cambodia | Your passport needs at least 6 months of remaining validity from the day you leave Cambodia. Airlines at Suvarnabhumi and Don Mueang check this strictly — if your passport expires sooner, you'll be denied boarding. | Required |
| Return or onward ticket Proof of departure from Cambodia | Immigration at Phnom Penh and Siem Reap airports asks for a return or onward ticket before they stamp you in. Budget airlines like AirAsia and VietJet also check this at check-in — have a printed or digital copy ready. | Required |
| Proof of accommodation Hotel booking or host invitation | Immigration officers rarely ask for a hotel booking, but airlines sometimes do at check-in. Have a printed or digital confirmation for your first night in Cambodia — a booking.com reservation or an invitation letter from a host works. | Recommended |
| Proof of funds At least $300 USD or equivalent | Officers almost never ask for proof of funds for a 14-day visa-free stay, but the rule says you need at least $300 USD. Carry some cash in USD — Cambodia runs on US dollars for most transactions. | Recommended |
Overstay fines add up fast
Overstaying even one day costs $10 per day, up to $500. Set a reminder on your phone for day 12 to avoid forgetting.
Land borders can be chaotic
At Poipet and other busy land crossings, touts may try to 'help' you with forms or charge fake fees. Ignore them — you don't need any forms and the entry is free.
What happens at the border
1
Prepare your documents before travel
Check your passport validity (6+ months from entry date), print or screenshot your onward ticket, and save your first night's hotel booking. No visa application needed.
2
Arrive at the border or airport
At Phnom Penh (PNH), Siem Reap (REP), or Sihanoukville (KOS) airports, follow signs to 'Immigration' or 'Arrivals'. At land borders like Poipet or Koh Kong, join the 'Foreign Passports' queue.
3
Present your passport and ticket
Hand over your passport and onward ticket. The officer will stamp you in. No fee, no form to fill. The whole process takes 2–5 minutes.
4
Collect your luggage and exit
After the stamp, proceed to baggage claim (if flying) then customs. You're free to enter Cambodia.
