ORIGINAL POSTERHello all.
I have an appt in January at Khon Kaen Immigration to extend my current Non-O 90 day retirement visa to a year. The email I received from them seems simple enough. It lists only 3 items, Application form, copy of passport, Evidence of income and/or account deposited in a Thai bank.
Does this seem correct for Khon Kaen? Looking at the nightmares from other immigration places, this is a breeze.
Is the application form the TM47?, it doesn't say.
I will of course bring the TM30 I used for the certificate of residence I used last month for banking and drivers license. Anything else I should bring? KK is an hour and a half away, so going back and forth is a real pain. I did get a passport photo the other day, but it doesn't look like I will need it.
Thanks for the replies.

TLDR : Answer Summary
To extend your Non-O 90 day retirement visa to a year at Khon Kaen Immigration, you will need to prepare the following documents: the TM7 application form (not the TM47), a copy of your passport, and evidence of income or funds (800,000 THB in a Thai bank account). It's advised to also bring your TM30 certificate of residence and extra passport photos, as additional forms may be required on-site.

Khon Kaen is usually easy, and their list sounds right. The form is TM7, not TM47. Bring TM30, passport photos, and full passport copies just in case. For more travel and expat tips, look up Landscape Hub

ORIGINAL POSTERI put 800k in my K-bank account within 3 days of opening the account, 6 days after arriving here. The 2 months of seasoning will be up on Jan 14, I have an appointment on the 15th. I will fill out the TM7, not the 47. The letter guarantee, since it is K-bank, I should be able to get it the same morning? Or the previous day? Does it need to be the same location where I opened the account? Thanks.

The application form is TM7. Normally there are also at least 2 more forms to fill, STM2 and STM9, some other provinces have even more forms; but lucky you, perhaps Khon Kaen IO is really an exemption from all others with that few requirements.

@Greg **********
the guarantee letter is only confirming the funds on the day it is written. They will need statements to prove the seasoning and usually an update bank book on the dayGreg ***********
@John *********
I see we disagree on this matter, again . . . . . . the "guarantee letter" is the statement 🙂 . . . . . At least in my case. I always ask the bank for the "rab roong thanakan" for THREE months, just to be on the safe side, should a new officer on Immigration ask for a 3-months seasoning. . . I also present my passbook which gets updated every month for 12 months, freshly updated on the same day and a receipt of a small ATM withdrawal on the same day, before I enter the bank and ask for the passbook update and the 3-months statementJohn **********
@Greg **********
I only update my bank book once a year, usually on the day I go to immigration so I always need 12 months of statements. It's the only day in the year I set foot in my bank.Jim *******
@John *********
If I have 850K THB in my Thai bank account. The day I apply for 1 year extension of stay, I withdraw 10,000 THB (leaving 840K THB in the account) and get my bank passbook updated (on the ATM). Would that serve the same purpose with Immigration?
Or, I need something more from the bank?
That moment is like 10 months from now.
John **********
@Jim ******
there's no problem with withdrawing the 10k as long as it doesn't put you under 800k, which has to be in your account for 2 months (3 in some places) before you apply for the extension, it has to stay there for 3 months after and can't go below 400k at any pointJim *******
@John *********
Thank you John. All what you said will be in place (the account untouched, just to show some proof of life, thats i why is that withdrawal action). Reading about some bank statements.In my case, nothing more than same day bank book update?
John **********
@Jim ******
as you can see above it varies by immigration office but you are going to have to show you met the requirements of your previous extension as well as the upcoming extension. For me that means 12 months bank statements, a guarantee letter from my bank and my bank book updated on the day I go to immigrationJim *******
@John *********
I will be on 800K THB or more in my Thai bank account , untouched. (Kashihorn Bank). Never monthly feed into my bank account.What guarantee from any bank if one (like me) is on 800K THB?
Other than bank pass book with the funds printed?
John **********
@Jim ******
i always just ask my bank for a letter for immigration and 12 months statementsJim *******
@John *********
So, my 850 K THB is rubbish, shit?John **********
@Jim ******
it is also a requirement. Not sure what you are trying to sayJim *******
@John *********
Trying to say, you did not get it, 800K THB overrides your posts. Untouched, 800 K THB , always there.What can you say against that?
John **********
@Jim ******
you still need to show its been thereJim *******
@John *********
Sitting there 9 months, 800K THB plus.Greg ***********
@John *********
I always leave my bankbook with my GF, so she updates it every month (I work with this account). If I would miss a month or two updates, the movements in my account would appear as "accumulated activity" - which means a dozen of transfers and expenditures get accumluate in one entry. Immigration could theoretically claim that this "accumulated" entry does not prove that the deposit never went under 800K respective 400K, so they could theoretically give me a problem and ask for a more detailled 12-months bank statement. I am glad they never were that strict. My Immigration is in Sisaket, I just visited them today to pick up my new 1-year extension of stayGreg ***********
@John *********
okay, then you are using the 12-months 65,000 THB transfers proof. . . . . . . Myself I got the required 800,000 THB in my bank account, and Immigration wants to see the a bankbook that shows every month, back from 12 months ago, to check the 800,000 THB weren't undercut during the 3 months after getting issued the EoS, and never went under 400,000 in the rest of the year. This and just a " rab roong thanakan" - the bank letter that confirms in my case to be safe - a 3-months seasoning (actually only 2 months of seasoning required and confirmed by the bank statement or letter - completely irrelevant how you call this document) . .we don't seem to be talking about the same thing, mate.John **********
@Greg **********
I also use the 800k method. The letter for the 65k method is different and actually lists your overseas transfers. The only difference seems to be my immigration (thankfully) doesn't want to see the bank book updated every month and prefers 12 months statements to verify I honoured the terms of the visaGreg ***********
@John *********
so, it is just the difference in both of our Immigrations. My Immigration is satisfied with seeing my bankbook to prove I complied with the 12-months deposit requirements. They don't need an extra 12-months of account statements . . . At the moment we are discussing the exact same topic in my German visa advice FB group, it's interesting to see that Immigration offices are deciding on their own what's whatReply to

The financial proof depends on your citizenship. If you are from UK, USA, AUS or Canada, for the first year extension of the stay permit, you need a minimum of 800,000 THB in your Thai bank account, which on the day of your application must have been sitting in the account for minimum 2 months, and your bank must confirm it with the "bank letter of guarantee" (rab roong thanakan). And if you intend to buy a re-entry permit (either single or multi) for the 1-year extended stay permit, on most Immigrations you will need two passport pictures
