I am on an 'O-A' visa and have to do my first extension of stay in August.
I understood that it was necessary to have the full 800K in your bank account 2 months prior to the due date.
But, today I was told it is three months, prior to the due date.
Can you please advise the correct length of time.
TIA
TLDR : Answer Summary
The correct length of time for maintaining the 800,000 THB in your bank account prior to applying for an extension on an O-A visa is at least 2 months before the application date. After the application, it is also required to keep a minimum balance of 400,000 THB for the rest of the year.
