What should I do if I have a non-refundable return ticket for my 60th day in Thailand but only a 30-day visa exemption?

Check your passport stamp date. You’re probably good already.

I don’t understand the issue the ticket is non refundable but your only changing the return

If you hold a Philippine passport

(ref your previous comments here), you’re entitled to a 60 days visa exemption and free stamp upon arrival and you’ll be fine with your 60 days return/onward ticket.

If you’re from one of the 93 countries allowed to enter visa exempt - that is with no visa, just a free entry stamp - then you’d get 60 days on entry.

There is no free visa for 30 days.

Bear in mind that the day you enter is day 1, so you will be stamped in for 59 further days.

Do the math and work out if you need an extension and if you don’t get one that you’d be happy with an overstay stamp and possible fine for the one day over.
