When I first apply for an extension in Thailand of an โOโ visa based on marriage, must I have 400,000 in a Thai bank for 2 months beforehand - OR can I show a monthly income from overseas into a Thai bank of at least 40,000 (going back for a year)?
TLDR : Answer Summary
To apply for an extension of an 'O' visa based on marriage in Thailand, there are several options to meet the financial requirements. You can either maintain a minimum balance of 400,000 THB in a Thai bank account for at least 2 months prior to the application or provide evidence of a monthly income of at least 40,000 THB from overseas, supported by a consistent record over the last 12 months. Alternatively, you could submit tax and SSO payments for a minimum salary in Thailand of 40,000 THB for three months.
