„when the money gets short“ ? . . how are we to understand it, as that’s a critical question.
Remember, in order to maintain a “retirement extension” by a deposit method, you are supposed to keep the 800,000.- Baht in the account for 3 months after being issued the extension, and during the rest of the year the money mustn’t go under 400,000.- Baht.
As long as “when the money gets short” doesn’t mean that you are violating this rule, you can always during the one year of the extension, change the reason from retirement to marriage.
However keep in mind: should you violate the rule at one point or the other, you are in overstay from that moment on.
