What documents do I need for a 12-month extension on a Non-O retirement visa in Thailand?

I would take the same docs you had to use when you applied and got your non o with the bank statement letter ,that should cover everything , i heard you need to get the bank letter the same day you go to the office for your extension .The statement ,your tm30 proof of address and passport the 3 most important of course but take anything else you have in case.

yes, only your "main" branch is going to issue the letter. If you move to a different location, you need to establish your new residence at the local branch. It can be done with a "certificate of residence" from Immigration

After having entered Thailand, you need to get registered in your accommodation per TM30 within 24 hours of arrival in the premises. If you rent or live in a friend’s accommodation, the landlord or the friend has to register you.

Immigration will only service you if you are properly registered in your accommodation by the TM30.

Every landlord, friend or hotel needs to register you within 24 hours of your arrival in the premises. While hotels do this automatically online, many landlords and friends are not aware of this or haven’t registered their house or rooms in the system. It is your responsibility to ensure that you get properly TM30 registered.

Within this 90-days stay permit period, you have plenty of time to arrange for the application to the “1-year extended stay permit based on retirement” (which people wrongly refer to as a “retirement visa”- actually, this thing is not a visa. It is an extended stay permit)

In order to apply for the “90-days single entry Non-Imm-O retirement visa” through the online E-visa system at the Royal Thai Embassy of your home country, you can use the proof of income of a monthly minimum of equivalent of 65,000 THB, by using your original pension statements or other income documentation.

Or you use a deposit of a minimum of 800,000 THB or the equivalent in your home country currency, or on your home bank account, or on a Thai bank, or just anywhere in the World – as long as the account is in your sole name

However, for the application inside Thailand for the “1-year extension of stay permit” out of the 90-days Non-Imm-O retirement visa, if you are a citizen of a country, whose embassy in Thailand does not issue the “income affidavit” any more (which are the embassies of the USA, UK and Australia, Norway, Canada and Belgium - AFAIK)

you would need proof by a “12 months bank statement”, showing that for the past 12 months, you have been transferring from abroad to your Thai bank account a minimum of 65,000 THB, consecutively month for month

If your embassy still issues a legalized affidavit of income, you can use this method for the financial proof, as long as you can show a monthly income or pension of a minimum of 65,000 THB

For above mentioned citizens, in the first year there is no other way around than depositing a minimum of 800,000 THB in your Thai bank account and use this deposit for the financial proof. For the application to the “one year extension of stay permit based on being over 50/retired” you need to show a minimum of 800,000 THB in your account and the funds must have been sat there for a minimum of 2 months, and you got the “bank letter of guarantee” that confirms this.

NOTE: It is income method OR deposit method.

And there is a third method, called the “combination method”:

A combination, a mix of income and deposit.

Some immigrations don’t allow the combination method in the first year. And some Immigration want the deposit part to exceed 400,000 THB. The combination method means that the sum of the deposit AND the monthly income exceeds 800,000 THB in one year.

But let’s continue with the “normal method” (visa issued in your home country, followed by the application to the Extension inside Thailand):

On the day of application to the 1-year extension, the 800,000 THB must have “seasoned” in your account for two months, and this has to be proven with the “bank letter of guarantee” (rab roong thanakan).

What else do you need on Immigration?

*** Immigration might ask you to present your updated bankbook, and a receipt of a small sum withdrawal at an ATM of the same day.

*** a copy (and original) of your passport detail page signed in blue ink

*** a copy (and original) of the .pdf visa document signed in blue ink

*** a copy (and original) of the printed TDAC (if applicable) signed in blue ink

*** 1900 THB in cash

*** the TM7 form you can fill out at the Immigration

*** Immigration will ask you to sing several “exclusion of responsibility” forms (STM)

You should visit Immigration asap after you entered and ask them for the handout list of requirements. Some Immigrations use an individual approach to the official rules.

After been issued the “1-year Extension of Stay”, the 800,000 THB need to remain in the account for 3 more months. After these 3 months, the deposit shall never go under 400,000 THB. And before your application for the next “1-year Extension of Stay”, a minimum of 800,000 THB must have seasoned in the account for two months, again

When you get issued the “1-year extension of stay”, you should always buy a re-entry permit for it.

A re-entry permit will keep your 1-year stay permit alive in case you exit Thailand before the expiry of the 1-year stay permit.

A single re-entry permit is 1000 THB on Immigration. A multi re-entry is 3800 THB.

With a multi re-entry permit, you can exit and re-enter as many times as you wish during the whole 1-year stay permit period.

Good Luck and a great time in Thailand

One thing you will need is a 'Notification of Residence' from the house owner, with copies of the house book, the owners ID and a Power of Attorney if the house owner is not present...

Application form, photos, tm30, 90 day report, letter from bank, statement of funds from bank up until day of immigration appointment, copy of bank book, copy of passport, entry stamp, tm6, current visa

When you go and get your list from immigration ask if you need a witness, I turned up with everything they needed but no witness, no one told me about that.

Love it up in Maha Sarakham. Was there a few weeks ago. My finance is there. We will be joining you in the future

Yes its so easy to that even kids can do it .

You need to bite the bullet and go to your immigration office and ask them for their handout listing the requirements. That's because each immigration office sets their own requirements, and they change from time to time. The best practice is getting their updated list every year before you will go and apply.
