What are the requirements for extending my visa as a spouse of a Thai citizen regarding Kor 2 and bank statements?

The user inquires about the renewal of a visa extension related to being married to a Thai national, specifically whether a new copy of Kor 2 is necessary and the age of bank statements required for the extension application. Multiple comments suggest that a Kor 2 form should be updated and that bank statements should ideally be no older than 7 days at most, contingent upon the immigration office's requirements. It's also noted that for the visa extension, it is important to ensure that a minimum balance of 400,000 baht has been maintained for at least 2 months prior to application.
