What steps do I need to take to obtain a TM30 for my visa extension in Thailand?

Send your host this link.

It’s free for them to register and easy to set up in a few minutes. Then they can register you and other guests easily in a couple of minutes.

At the bottom there are links to a manual in Thai and English to take them through the steps as needed.

My TM 30 wasn’t ready until the next day. Keep that in mind.

if your a-hole AirBnB host won't register you TM30, all you can do is check into a hotel for 1-2 nights and ask them for the printout of the TM30 registration, visit Immigration and apply for the 30-days touristic extension

I would check in to an hotel on Sunday as Tod says make sure they will give you a copy of the TM 30 they send to immigration.

So you have a real tourist visa <- that you bought from a thai consulate before you came here and got 60 days when you entered?

OR

Did you just show up here and get stamped in for 30 days free stamp (visa exempt)?

I ask because you go to different places for the 30 day extension

Free stamp (visa exempt) - IT Square Laksi Plaza, floor 3

Tourist Visa - Chaengwattana Building B, floor 2 section J

Both immigration offices are pretty hard on you having a TM30 filed and there is no 'hack' to get one. Many people have been forced to check into a hotel for a day to get a TM30 issued for their extension after they were knocked back

BUT

WIth that being said, some people reported they weren't even asked for a TM30 when they got their extension.

All you can do is try, it'll either fly or it won't
