Can I switch from the THB 800K modality to the THB 65K modality for my retirement extension in Thailand?

@Max *******

an agent's only goal is to make a profit. They don't care if they give you good advice.

Most offices will allow you to switch from 800,000 to the 65,000 per month, but every office also has their own rules so the only people who could answer that for sure would be Samui immigration.

You just have to be very careful because you need to meet all the rules from the previous 1 year extension while also meeting the rules for next year.

So if they allow you to switch you would need to show that your bank account had 800,000 when you applied for your previous 1 year extension and that you kept the 800,000 in the bank for 3 months after your extension and then never let it drop below 400,000 the rest of the year. They will ask you for the full 12 months of bank statements to confirm this.

You'll also need to show proof that you transferred in 65,000 baht every single month from overseas for the 12 months before you apply for your next extension, which is what you'll need to show to prove you qualify. So you'll be meeting 2 different requirements at the same time to switch.
