most let you apply for the one year extension when you have less than 30 days on your 90 day stamp, but Koh Samui can be different, only doing it at less than a week. They are this way with tourist visa extensions, and might be in your case, but just ask them when you get your initial 90 day stamp. The bt800,000 has to be in your account for at least two months before you can apply for the one year extension, so get it transfered right away. You can apply for the initial 90 day stamp as soon as you have the money in there though. Check with your UK bank for their SWIFT transfer requirements. Bangkok Bank's SWIFT code is on their website, or you can just ask them.

@Steven ********

just a few things to be aware of. The bt800,000 in your Thai bank account must show as coming from overseas, from outside of Thailand. This is the easiest visa extension to get. It is not complicated at all. Just take two letters from your Thai bank to immigration. One stating that it is your bank account in your name only. The other is a deposit summary showing the bt800,000 in your account. Take these to immigration, they are only good for seven days, and immigration will either issue the 90 day initial stamp, or send you for a few other documents that you should be able to get before the seven days runs out, but most issue you the 90 day stamp, letting you get whatever else is needed for when you apply for the one year extension. It is actually quite easy to do after you have your bank account. For the one year extension, and the extension the following years, your account only needs to be brought back up to bt800,000 two months before you apply, and must stay at that amount for at least three months after you get your one year stamp. Lots will try to say Wise is the best way to transfer that first bt800,000, but for that amount, and to never have any problems of it being questioned, a SWIFT transfer is best, and is never questioned by the government, especially if you want to transfer it out of the country, if you change your mind down the road. Also, if you are under the legal retirement age in your home country, but on a retirement visa extension here because you are over 50, expect in future years to be required to show that the money you are using to live on in Thailand has had the legal tax paid on that money. This went into effect January 1st of this year, but it hasn't been determined yet how it will be enforced for foreigners living here long term, but in the very few following years it will be. Just be aware of this change. Keep your tax filings records handy just in case. If you are over the legal age to receive your pension then no worries, as Thailand has good dual tax treaties with the UK. Also immigration at Koh Samui can be temperamental at times, coming up with ways to make a few extra baht. Take your TM30 with you, copies of your passport, and your lease agreement, besides your bank letters, to be well prepared, and passport photo just in case. Or just go there first, and get their handout of their local requirements, as you've already got your Thai bank account, and that is the biggest hurdle in doing it all here.

Lots of tourists base out of Thailand when visiting other countries. Your proposal follows a pattern of being a tourist so you won't have any problems. You aren't trying to stay in Thailand long term as a tourist. You are being a tourist based out of Thailand.

For a total of 90 days with the extension, then you have to leave Thailand.

You will need your marriage license, and amphur registration document, then a copy of your wife's Thai ID card, and a copy of her house book listing. A copy of your passport, and the application form.

It all depends on how much you are planning on sending, and what it is?

@Kim ********

not using IBAN numbers you haven't.

@Kim ********

be fully aware that Thailand does NOT support the use of IBAN numbers. They use SWIFT transfer, and local account numbers. You can not listen, and find out for yourself...lolol.

@Kim ********

each bank has a SWIFT code, and you then designate your account number for that bank. That is how it has been done for decades and still is.

Use the SWIFT transfer method, not IBAN, and you won't have any problems with the transfer for large amounts.
