no, but has to be in your bank two months before the extension day, and it is recommended to leave it there during your under consideration period. When you go back to get your stamp for the remaining 11 months, you can if you want take all of the money out, as long as the 400k is back in two months before the next yearly extension. Hope this makes sense to you.
The 400,000 baht must be seasoned 2 months before you apply for your extension. Most immigration offices will only accept the monthly income of 40,000 baht if you are working inside Thailand. It is best to ask your local immigration office what they will accept
It is the law, but it is rarely enforced, but in this current climate they are clamping down on Farang’s, especially around the tourist areas, so be careful.
It still has to be passed by the senate, then approved by the King and the put in the Royal Gazette then after that have to wait another 90 days until it’s law, so after all of that possibly the latter part of the year.
