If you've already filed a TM30, then just a copy of the 'receipt of notification' is sufficient, which is usually stapled in the back of your passport.

You can download forms STM2, STM9, STM10, and STM11 as posted above from here; https://bangkok.immigration.go.th/en/downloads_en/

There are now 4 forms to complete; THE ACKNOWLEDGEMENT OF CRITERIA AND CONDITIONS FOR PERMIT OF TEMPORARY STAY IN THE KINGDOM OF THAILAND https://bangkok.immigration.go.th/wp-content/uploads/STM-2-FORM-2025.pdf The Acknowledgement of penalties for visa overstay https://bangkok.immigration.go.th/wp-content/uploads/STM-9-FORM-2025.pdf Affidavit of Family Relationship to Thai National https://bangkok.immigration.go.th/wp-content/uploads/STM-10-FORM-2025.pdf Consent Form for Fact-Checking and Information Verification https://bangkok.immigration.go.th/wp-content/uploads/STM-11-FORM-2025.pdf

Converting from an ED visa to a Non-B visa within Thailand is generally not permitted. While some sources mention that it might be possible with extensive paperwork and upon the discretion of the immigration officer, it's not a common or straightforward process. You will likely need to leave the country and apply for the Non-B visa at a Thai embassy or consulate abroad.

No, that's for a person having residency, as in permanent residency. Your son will only have temporary permission of stay. That was the advice given, for good reason. On entry, she will be granted permission of stay for 90 days. File a TM30. Open a bank account (must be in her sole name), deposit funds. Within the last 30 days of that 90 and when the funds have been season for 30 days, she can apply for the 12-month extension. My other concern is the documents your wife must bring to prove relationship for the extension application. Whilst Thai Embassies will accept marriage certificates, birth certificates to issue the appropriate visa, Thai Immigration do not accept foreign documents without being 'legalised'. Basically, they must be authenticated in your home Country, then the Thai Embassy certify it. On arrival in Thailand, any documents must be translated into Thai, then legalised by Thailands Ministry of Foreign Affairs.

Entering Visa exempt Immigration offer the opportunity to apply for the Non O at a local Immigration office but only for certain criterias. This is the Immigration list. https://bangkok.immigration.go.th/en/issuing-and-changing-type-of-visa/ I do not find the reason you describe as being available.

Residence certificates are usually only issued for purchase of transport or obtaining a Thai driving licence. You may have an issue getting one for the purpose of opening a bank account.

On what basis would your wife apply for the Non Imm O visa at an Immigration office, which requires more than a single visit.

Not if you meet the financial requirements and don't use an agent. As @DrJack54, no such problems using Wise. What are you stating as the 'reason' for the transfer?

Many of those who stay here long term use 'Wise' as a transparent and very affordable way to send funds from overseas. https://wise.com/gb/send-money/ Where does your wife intend to reside, this will determine which Immigration office she will use. There are other Immigration formalities to be aware of in Thailand. Filing a TM30. Opening a bank account.

If I'm reading your situation correctly, your son has been accepted to study at an International School in Thailand, pursuant to clauses 2.8 or 2.9 of Immigration order 327/2557. Your wife intends to stay in Thailand during his education period at an International School. In that situation, your wife would be required to enter Thailand with a Non Immigrant 0 visa. The requirements for her to extend her period of stay for a further 12 months are in Clause 2.11 To expand and in agreement with @DrJack54, your wife should obtain the Non Imm O visa from the Thai Embassy in your home Country before entering Thailand. Firstly, does your wife already have a bank account with a Thai bank? Apart from the 500K THB Immigration requirement, she would need initial additional funds for rent, travel and living expenses. Whilst there is nothing in Immigration Orders stipulating that the 500K must come from overseas, I wouldn't want to carry 500K + in cash. Sufficient funds to meet immediate needs, yes, but I'd transfer the 500K to a Thai bank account.

The Kor Ror 2 is issued merely as evidence that since you registered your marriage, there is no record of divorce. It cannot confirm you are living together in a de jure and de facto relationship. The STM10 form (Affidavit of Relationship) signed by your wife and now a witness states you live together in a de jure and de facto relationship.

You're supposed to regularly update the passbook. It sounds as though they are eventually starting to check that those using the Embassy Income letters are actually transferring the required financial income requirement to support their stay in Thailand. I wouldn't be surprised if all the foreign Embassies ceased issuing Income letters within the next couple of years.

When you transfer stamps to a new passport, they will update the systems with your new passport number. Any email notification you receive of an impending online 90 day notification date, will detail your new passport number. You also shouldn't have to file a new TM30, but ............. I would ask that question, it being Jomtien!

You have it the wrong way around. The 800K is 2 months prior to submitting the extension application and 3 months after the extension is approved, then you can withdraw up to 400K.
