Can I renew my 1-year visa extension on my own instead of through an agency if I have a new bank account and a different TM30 address?

Bank account and 1 year extension.

The bank account was opened by an agency. I hardly remember where the branch was (somewhere in Bangkok, China Town). I got my first 1 year extension with the agency.

My 2 questions:

1. I opened another bank account with Kashikorn Bank where I deposited 850K THB. Would that different bank account be a problem when renewing 1 year extension (26. September 2026)?

I have Yellow Book, Thai DL, Thai Pink ID, bank book.

2. My TM30 when the 1. year extension was granted, was with some address in the provinces (via an agency). The day after arrival to Thai (October 30 2025) , I submitted TM30 with my my current home address in Bangkok (Samut Prakan). That TM30 will never change.

Does that TM30 override whatever address and TM30 the agency logged in?

Trying to check if I can go on my own to Immigration for the next extension or am I locked with the agency?

TLDR : Answer Summary
The user is inquiring about renewing their 1-year visa extension without the assistance of an agency, given that they have opened a new bank account with KASIKORNBANK containing the required 850,000 THB, and have updated their TM30 submission to reflect their current address. Responses from the community address the importance of the bank account timing and whether the TM30 override is applicable, along with details about documentation requirements for the extension.

You will have to show immigration both statements from bank showing transfer. I had to show twelve months of original bank account. Retirement visa I used agent did the extension myself with the help of Visa assistance at Jomtien immigration. 3 months later had to to show current balance in bank book.

Never heard that the bank account has to be 12 months old.

Non O 90 days retirement visa is technically enough to open bank account, deposit 800K THB into it and after 2 months (funds seasoning) apply for 1 year extension, still within the 90 days of Non O visa stay.

Where did you get 12 months rule from?

Looks like you’ll need to apply for a non-o and start over then you can use your money

I would not mind that. I saw a post, an agency said 12,700 THB if I want to revert to my own funds and they do the rest. Just want to clean up the agency's admin work.
Bob **********
@Jim ******
just start over it’s only 2000 baht for the non-o and start bringing in your monthly transfers and you can use that for your second extension

No monthly installments, I already have 850K THB in Thai bank my account. Will be sitting there for 9 months before I apply for the next 1 year extension. Will just leave it untouched.

The real question is - do I have to hear of that agency again?

@Jim ******
you can use any agency, don't have to keep using the same one. But if you're not clear for this one (which sounds like the case) you could try an agency that will use your immigration office and your own money which will clear you for your own next year.

12,700 THB is their charge for that. I think I am set to do it myself now. New Non O, no agency.
Brandon ************
@Jim ******
Certainly an option.

@Jim ******

@Peter ********
how can he get a bank letter if he doesn't know the branch and, more importantly, the 800k was not seasoned and maintained to meet the requirements of the first extension?

@Graham *****
It is a different bank, near my Bangkok home. The first bank was via an agency.
Peter *********
@Graham *****
he says he has funds in another bank seasoned ?
Graham ******
@Peter ********
his new account is recent so can't be used to meet the requirements of his current extension

New extension, due in September 2026.
Graham ******
@Jim ******
yes so the account will be 10 months old - no 12 month statement;)
Jim *******

I know that. Someone was pulling 12 months out of the blue.

@Graham *****
Why 12 months old? Where did you find 12 months?

Technically, with Non O 90 days one should be able to open bank account , deposit 800K THB, let is season for 2 months and get 1 year extension within those 90 days.

Why are you bringing in 12 months?
Graham ******
@Jim ******
You have to keep the 800k there for the first 3 months of the extension and never drop below 400k. You need to show you met these requirements when getting a new extension. The OP is not getting the initial Non-O or a first extension but a new extension. ;)

I was hoping so. To break the link with the agency. My TM30 is with my Yellow book, my address and Thai Pink ID. I own the condo.
Bruce *****************
@Jim ******
there is no link, they like to tell people there is...just do if yourself, thats normal and legal
Brandon ************
1) When did you deposit the 850k? Was it deposited before the agent got you an extension? If not, then you cannot get this extension yourself.

2) What province is the extension from? If it's from this far flung province, it's probably known for agent extensions and likely they'll tell you to use an agent again when you go into immigration and they see where your last extension was from. The TM30 isn't really relevant.

"1)When did you deposit the 850k? Was it deposited before the agent got you an extension? If not, then you cannot get this extension yourself."

Is it where the catch is? I could not deposit 800K before I had bank account. Agent opened it and got 1 year extension.

With that extension, I opened another bank account, Kasikorn bank, near my Bangkok home that I want to use for next extension. The funds are in there, will be sitting for 9 months from now when the next extension is due.

Now, I can not use the new account without starting from scratch?
Brandon ************
@Jim ******
you could not have gotten your extension by yourself with money that was only in the bank for 9 months
Jim *******

@Brandon ***********
I may well let the extension expire, come back on a new Non O and do it over again myself. Then I will have 1 year money, account, everything.

Starting from scratch with money in my account for longer than 2 months should be OK?
Jim *******
ORIGINAL POSTER
850K THB deposited after the first 1 year extension, when I opened bank account with Kasikorn myself (mid November 2025).

The province was Chai Nat (the stamp in my passport) with 1 year extension. I entered Thai October 29. 2025. on it, no problems.

Then, according to what you said and my understanding, I can simply let this extension expire, come back on a new Non O 90 days after September 26. 2026 and do it all over again, myself.

Now I have it all, even more.

@Jim ******
that's the cleanest way to do it but because you can show you have had over 800k baht in a bank account for over 12 months you might get away with just doing an extension if the don't object to the iffy stamp
Jim *******
ORIGINAL POSTER
@John *********
That stamp I would let expire, become invalid. Do I care? I will be in Japan, not in Thai at that time.

A new Non O visa when I can do it all myself.

Where did you find 12 months of my bank account my money sitting there? What am I "getting away" with?
John **********
@Jim ******
you said you entered October 2025 and put money in your bank November 2025. An educated guess says the agent got you a 90 day Non-O and 12 month extension at the same time. So therefore were you just to go for an extension you would be able to show you had the required funds in your account for the duration of your extension. Whether another immigration office would deal with you considering it is not a strictly legitimate stamp
Jim *******
ORIGINAL POSTER
@John *********
It is a legitimate stamp. Souvarnabhumi Immigration let me in with that, no questions. I am in Bangkok now, on that stamp.

I deposited the money into my newly opened bank account, nobody knows of that, until my next extension of stay comes up.
John **********
@Jim ******
OK so you entered with a legitimate 90 day Non-O visa and then used an agent to get the 12 months extension of stay. Kind of comes to the same thing
Graham ******
@Jim ******
yes, best to start again clean using your legit funds to get your initial Non-O then extension
Jim *******
ORIGINAL POSTER
@Graham *****
Not a big deal, online, a new Non O 90 days. I have Yellow Book, Thai Pink ID (lifetime), Thai DL, forever lasting TM30.

Might take me a day to sort it out afresh, without any agency.
