we can only assume that he cannot fulfill the financial requirements, because why otherwise would he have stayed in Thailand with the multi entry Non-O married from Savannakhet? A many married people are in the same situation right now. Visa vaild but "admitted stay stamp" expired, everybody on amnesty and no border bounce possible except one flies back to his home country and comes back. A Dutch guy (story from 2 weeks ago) did his and he spent 300,000 Baht on such a "visa run" recently
the German embassy never allowed anyone swear on the Bible on how much money they earned monthly 😀😀 . . they ask for HARD proof. So the immigration still accepts these letters
the immigration does in fact accept income letters legalized by the German Embassy Bangkok for income proof. I know a handful of married Germans who use this letter
you don't loose any days if you apply for the 60-day family visit extension anytime in September. The 60 days will count from 27 September on. This will give you enough time to season 400.000 THB in the bank for 2 months, then apply for "1-year Extension of Stay based on marriage" . .with this Extension, no more border bounces are needed

sure they don't accept joint account unless you haven't parked 1,6 million plus in it. But they will accept two separate accounts, and they will even accept only ONE account with +800.000 THB in ONE's name, and the married partner can go "piggyback" or if you don't like to be compared with pigs, "trailing" is another valid term. WHAT and WHICH parts of all the advice above, do you not understand ?
