You must have cut it very close with your extension application as 90 days from your entry date is 30th August which luckily was a Saturday. You need to keep a minimum of 800k baht in your bank account for 3 full calendar months from the date you received your extension of stay and can't drop below 400k baht at any point during the extension of stay

Couple of things.

1. term deposits are not normally acceptable, money needs to be in a. Standard bank account

2. You need a letter from your employer giving you permission to work remotely from Thailand and stating that you will not work with any Thai entities or clients

Get the 90 day Non-O before you travel to Thailand, then just extend as normal

If you are applying via Washington they want $16k usd but there is no requirement to season the funds. They want 3 months of statements with an ending balance showing the amount

Get the Thai Privilege visa, it's the only one that works for someone retired at your age. You can't get a retirement visa until you turn 50

@Philip ****

nope. Capital gains fall under Thai tax, principle won't

You need to be patient.

Remain where you are until the visa process completes even if that means having to change your travel plans

TDAC filed within 3 days of your planned date of entry, a printout of your evisa and your passport

@Marc *******

the onus is on you to complete a Thai tax return and pay any tax due.
