Do you need a bank statement for the past year to extend a Non-O retirement visa in Thailand?

The requirement for bank statements when extending a Non-O retirement visa in Thailand varies depending on individual circumstances and immigration office policies. Generally, it is expected that applicants provide either a one-year bank statement or evidence of maintaining the required 800,000 baht for at least three months. Some users reported being able to extend their visa with just six months of statements for their first extension. It's advisable to check with the local immigration office, as practices can differ and may require additional documents like updated bank passbooks or income letters.
