Do I need to show 400k baht in my bank account when applying for a 12 month Non-O retirement extension after a Non-O marriage extension?

When transitioning from a 12-month Non-O marriage extension to a Non-O retirement extension in Thailand, it is generally not required to show a year-long bank account balance of 400k baht. The requirements may vary by immigration office, so it's advisable to directly consult your local office for their specific regulations. Some offices might still want to review if you maintained the previous financial requirements. Always check with the immigration office to clarify any unique local requirements.
