A student visa is only required by those entering the country for the sole purpose of attending an education facility. Your son is entering as a dependant child presumably of school age, meaning there is an expectation he will attend some form of school to maintain his education. There are thousands of children of expats on various visa's here as dependants and attending schools no ed visa required. You yourself may decide to enroll in a school to learn Thai to ease your stay, you don't have to get a different visa for that.

You were quite lucky when you visited the imigration and asked the question, as you could have come away with a fine. Not for the 90 day report, but for the tm30. If you do the 90 day report online you are supposed to enter the address you have spent the previous night at, which should equal the most upto date tm30 so the addresses are the same, only when doing the report at an Imigration office do you have the restriction that the office must cover the area of the tm30 address and the 90 day must be the same.

If your moving here in 2025, all money you currently have can be treated as non-assesable and can be moved to Thailand tax free at any point in the future under the current rules as you dont become a tax resident until 2026 and subject to tax filing rules in 2027. Any interest you make in 2026 onward and remit would be subject to tax, but you can claim credit for uk tax paid on it prior to calculating any tax owed. Just make sure you have adequate records of monies held as of end of 2025.

@Pete ******

there was an update published in the gazette on 16th June 2020 enacted 30th June 2020 removing the need to reregister the foreign national after temporary travel if returning to the previously registered address within the validty of that notification. It wasnt well reported at the time. And length of temporary travel is ambigous.

@Pete ******

actually the rules say you dont need to notify via a tm30 if you are returning to a registered location within the checked in period. (Changed ). So if your tm30 has a null checkout date its not required under the rules. That said many offices will insist on an updated one when physically interacting with them and the form has to be shown. I never bother during the year for my 90 day reports, but do an updated one for my anual extension of stay.

Since about 2021, From a legal point of view, if you are returning to your permantly registered property (as per tm30) within the registered stay period, [checkout date future or null], there is no need to re-register, this applies to both internal and external travel of Thailand. This should be fine for 90 day reporting purposes eg on-line. However, if visiting imigration many offices will insist on a new TM30 (especially when the check-in date is prior to your visa extention or arrival in country date. Problems can arise with internal travel, where your last hotel/etc don't fill in the checkout date of their tm30, and this becomes your address on record. I travel a fair bit within Thailand to hotels and never redo my tm30 and dont have a 90 day reporting problem, but i always register a new tm30 for my extension of stay done at CW.

The training video online has been available for a couple of years, so its probably just a temporary glitch with the site. You view the video and answer some observation questions to prove you watched it (during & at end) anytime prior to the visit to dlt. When you completed the viewing you save and print the qr code to take with you.

You also need to take along your residence certificate issued by imigration for the purpose of opening a bank account

I think you'll find the under consideration period runs to the 'later of' 30 days or visa expiraration date. I use CW which is 20 days, and in 12 years never received a considerstion date end less than my previous extension date.

Stuart Hansen no one has said agents can't be helpful in securing visa 's when dealing with immigration and non-O type visa's.

However, the OP is not asking about this, the question is around LTR visa, which is through BOI, who technically work as the agent already.
