Do you need an onward ticket to re-enter Thailand after a short trip to Vietnam?

(I have been a country hopping tourist since September.)

Proof of onward transit :- long happily ignored by Thai immigration, has been known to be strictly applied in some instances (Indian passport holders beware). The requirement is for an international flight itinerary - NOT train, ferry, or other departure type

And be aware this POOT needs to be an airline ticket, a train ticket to Malaysia doesn't count.

OK guys believe what you want> BUT people have been refused boarding with ONLY a bus ticket out

as a bus ticket is about the same price as using onwardflights. why take the chance?

From ThaiEmbassy.com (not the official website of the Thai embassy):

They must have a confirmed return ticket to show that they are flying out of Thailand within 30 or 15 days of entry, as appropriate. Open tickets do not qualify. Travelling overland out of Thailand by train, bus, etc to Cambodia, Laos, Malaysia (including en route to Singapore), Myanmar, etc is not accepted as proof of exiting Thailand. You may be asked to show your flight ticket on entering Thailand. If you do not possess a flight ticket to show you will be exiting Thailand within 30 or 15 days of entry you will be most likely to be refused entry.

Do not risk saying I will buy a bus/train ticket out of Thailand when your visa expires- IT does NOT work anymore the immigration and airline staff are not stupid !

But a ticket on Expedia and use the 24 hr option to cancel , that way you have a proof of a ticket out of Thailand and it costs you nothing to cancel it 👍

@Shar ******

not true, must be a flight out

Use onwardflights.com
