Can a 60-day tourist visa for Thailand be obtained with a flight ticket 90 days after arrival?

Regardless of what you have been told... ASK YOUR AIRLINE...IF THEY REQUIRE A TICKET DEPARTING THAILAND WITHIN 60 OR 90 DAYS OF ARRIVAL.

It depends on the embassy at which you apply for your visa. Many do recognize that with the possibility to extend to 90, that's the appropriate amount of time to require onward travel within. There is no official requirement for proof of onward travel beyond that point, so if the embassy approves the visa, you should be ok.

Normally you’re allowed to get a 60 days tourist visa with an onward ticket within 90 days, but this is a bit embassy dependent. And normally no questions at the immigration, unless they start questioning you for another reason regarding your previous travel history to Thailand.

The real question is:

Can you buy the single entry tourist visa from the thai consulate in your country before you wing your way here showing onward travel in 90 days rather than the number of days you'll get stamped in for when you arrive here on that visa 😮

IF you can get the tourist visa application approved with onward travel 90 days out you most likely won't be asked for onward travel at all when you stamp in. 😉 BUT even if you were the officers at passport control know you can get a 30 day extension
