How can I request a 30-day extension after my initial 60 days in Thailand?

To do this, you have to visit the immigration office that is responsible for your place of stay.

Thai Immigration always talks about “visa extension”. They make no distinction between “visa” and “stay permit”, even though they are two different things. Technically, a visa cannot get extended. Only stay permit will get extended.

What do you need for the 30 day “tourist extension”?

Most immigration offices allow an extension if there are still 30 days left on your stay permit stamp

However, many immigration officers will tell you to come back a week before the stay permit expires. NOTE: You will not lose a single day by going early

To extend your stay permit by 30 days you need:

- A copy of passport page with personal information

- Copy of the stamp/visa page

- Completed TM7 form (extension application) The TM7 form is available at immigration

- two passport size photographs (many immigration offices now do this digitally however I recommend you have some on you)

- 1.900 Thai Baht, preferably the exact amount, because you won’t be given any change on most immigrations

It is highly possible that the Immigration officer wants to see a TM30.

The TM30 is the registration of your accommodation provider/hotel/guesthouse/resort, which must be done within 24 hours of your arrival at the place you will stay

In case you stay privately or in an AirBnB, the landlord needs to register you in the TM30 system and you will need a printout or screenshot of the receipt

Usually the officer, when he is entering your personal data in his computer, he will see that you were registered by the hotel. It would be advisable to carry a business card of your hotel

it is done on the Immigration office that serves the area where you are TM30 registered

Done mine today in less than 1 hour in Hua Hin . Very easy to do

You go to the immigration office that serves the province you are staying in and you apply for the extension.

It's not done online and it's not done at the airport.
