A friend of mine had exactly this problem recently. He went to immigration with a hotel business card, a recipt of his payment and the booking confirmation. He got his extension without any problem. It is then up to the local immigration authorities to how they proceed.

the only thing you can do is go to immigration.

I am afraid you are wrong. The house master has no requirement to issue a TM30 to their guests. They have a requirement to report to immigration only.

been visiting Thailand since 1989, lived here since 2016. I don't think that things change as much as you think.

@Paul *******

why would you leave it until 1 month before you arrive?

@Roberto ********

great point.

If you have a long term visa you can. On Tourist and visa exempt entries you remain on the 2 year.

all part of our modern world. 🤔

Too much of a risk to do nothing. Get a new passport ASAP.

@Gregor *********

just read your comment and unfortunately you are wrong. An extension of stay on a non immigrant O has different requirements to an extension of stay on a non immigrant O-A.

When you get a new passport then immigration will transfer your current visa into the new one. The transferred stamp will detail the visa type, O, O-A or whatever visa you are currently extending.

Maybe next time it will be best to check before you start disagreeing with more knowledgeable than yourself.
