POLICY CHANGE; BANGKOK
Anyone getting a yearly extension of stay based on marriage to a thai using banked money (400K baht banked for 2 months prior to your application) be advised:
They now require the money to still be in the account and above the 400K baht threshold when you go back after the 30 days. :O
When you apply for the year extension and get the 30 day under consideration stamp they tell you to leave the 400K baht in the account UNTIL you go back for the extension.
On that day you bring your bank book back with you AND to update your bankbook on that day too.
Once they see the funds are still there they'll ink the new year extension into your passport. :/
This is NOT written down anywhere in an official policy BUT I saw several people asked for their bank books and people being told to go update their bank books and make a copy BEFORE they could get the year extension.
This is ONLY for extensions based on marriage to a thai where people use the 400K baht banked money method of proving funds.
Just thought you people should know (especially you Bangkok-ianz married to thaiz) :P
TLDR : Answer Summary
A new policy for extending stay in Thailand for foreigners married to Thai nationals now mandates that the required 400,000 baht must remain in the account until the visa extension application is processed. Upon returning for the extension after a 30-day initial approval, applicants must present an updated bank book confirming the balance is still above 400K baht. This requirement is not officially documented but has been observed in practice.
