I am currently on a Non Imm B extension until August 24th. I plan to cancel my Work Permit and change my reason for being in Thailand to based on marriage. I understand that as I am working here the 400K doesn't need to be sent from abroad. I have the required documents based on the document I received from my local immigration office ready. I wish to know how close to the 24th can I go? What happens next? Do I get a 6 day extension and then go back with my documents to get a one month under consideration stamp before getting the 12 month stamp? I would really appreciate some clarification for my own piece of mind. Many thanks!
