changing from banked money to monthly income is the trickiest one because you have to meet the seasoning requirement the whole year for the previous years banked money extension AND you have to put in the required 12 months of international transfers to qualify for the monthly income method the next year.
So that means you need to keep the 800K baht in the account 3 months after you get your extension AND deposit 65K baht a month in each of those months to begin the 12 months of international deposits for the next extension, and after the 3 months you still need the balance of the banked money to stay above 400K the whole rest of the year until you FINALLY go apply for a new yearly extension using the 12 months of deposits ๐
