Can I enter Thailand on a 60-day tourist visa if my return ticket is 90 days after arrival?

There are three things at play here

1 - The tourist visa you're buying (which may or may NOT require you to show proof of onward travel when you apply)

2 - The Certificate of Entry/Thai Pass that you get (which may or may NOT require you to show proof of onward travel when you apply)

3 - The immigration officer you meet at passport control (who will NOT ask at all about proof of onward travel)

I think we've taken this topic about as far as we can. Sadly there is no uniformity between the thai consulates scattered around the globe. Good luck to one and all on your endeavor to get back into thailand (y)

For the last 6 years I have entered on a tr visa and stayed for 4 or 5 months, never had a problem only once did the check in question me so just told him I can extend my visa and take a trip to cambodia(pre covid)

Hi this is what I want to do in November, how do I apply for a 60 day tourist visa I didn't see that option on the Thai Embassy in London website?

There was an example of a guy coming from the states last week. He had all the right docs, an approved CoE but his flight out was for 90 days after arrival. The airline refused him boarding until he booked a ticket out within the inital validiry of his visa. As he had got there late due to traffic thet closed boarding before he could get on.

So its just hit & miss. I've been asked pre covid when coming on a visa exemption from Sri Lanka, but i also came in 4 other times without being asked i was also asked when I came in on my STV this time.

I’ve done that for many years (pre COVID ) and never had a problem, don’t know now right enough but will be going next month and doing trying the same

All I was trying to point out was

IF you get the COE/Thai Pass approved (and IF you get to check in with the airlines) with onward travel 90 days out that they will not have any issues stamping in here in thailand at passport control.

The airline MAY deny boarding if your return flight does not match your visa. Most airlines are not charging change fees at this time.

The airline could be an issue.

IF you get the certificate of Entry or the new Thai Pass approved for entry with a flight out 90 days from your arrival you won't be questioned by passport control at all when you stamp in .
