Thailand visa for Cambodians 2026: 14 days by treaty

What changed for Cambodians on 15 September 2026

On 15 September 2026 Thailand rewrote its visa-exemption regulation and cut Visa on Arrival to three countries, but the bilateral agreement that covers Cambodians was not part of that instrument, so nothing changed for a Cambodian passport on that date. What matters more for Cambodians is the position since June 2025: during the border dispute Thailand shortened the stay for Cambodian passport holders from the treaty's 14 days to 7 days and closed most land checkpoints between the two countries. Air travel to Bangkok continues, and immigration stamps the shorter stay on arrival. Treat 7 days as the working allowance, treat any land crossing as uncertain, and confirm the current practice with the Royal Thai Embassy in Phnom Penh or your airline before you book.

Before you fly

• Make sure your Cambodian passport will still have six months of validity left on the day you land in Thailand, along with at least one blank page for the entry stamp.
• Keep proof of funds on hand, since immigration officers can run spot checks and expect to see 20,000 THB per traveller, or 40,000 THB if you're arriving as a family.
• File the digital arrival card in the 72 hours before your flight lands, using the free Immigration Bureau portal, and keep the QR code ready for scanning on arrival.
• If you want more than 14 days, arrange an e-Visa or a Destination Thailand Visa before you leave Cambodia, since the visa-free stamp cannot be extended once you've arrived.

Staying longer than 14 days

The 14-day visa-free stamp itself cannot be extended, so if you know you'll need longer, plan for it before leaving Cambodia. Applying for an e-Visa in advance gives you a single entry of 60 days, which can be extended once more by 30 days at a Thai immigration office for 1,900 THB. Remote workers or those on longer courses can look at the Destination Thailand Visa instead, a five-year visa that permits stays of up to 180 days per entry, though it requires proof of 500,000 THB in funds and a 10,000 THB fee, and must be arranged from outside Thailand. Repeated short hops across a land border aren't a workaround either, since visa-free land entries for Cambodians are capped at two per calendar year.

At the airport

At passport control, Cambodians can't use the automated e-gates at Suvarnabhumi, since Cambodian passports aren't among the nationalities cleared for that lane; instead, head for the Foreign Passport counters and go through with an immigration officer. Have your digital arrival card ready, since the QR code it generates is what gets scanned at the counter alongside your passport. Filing it before you land, within the 72-hour window, means you won't be doing it in the queue.
