Wise TRX - “Funds for long term stay in Thailand” cited reason so the TRX shows as international Transfer when the bank statement used for Non-o extension.
Feb 25 till Oct 25 only 9 x 65,000 deposits: you will not be able to use the 65,000 route yet for 2nd extension. 3rd will be fine. You will need 800,000 2 months before October application (and prove you maintained 400,000 during the year + 800,000 for 3 months after 1st year extension)
If simply rejected (and not asked for further info) he did not meet the published criteria or made an admin mistake in the application form. Do check the criteria on the relevant embassy’s website and check the application form.
Your husband can get non-o(retirement) in his own country while you can try it in November in Thailand. The bank account may prove a catch 22 though. Always easier in home country and then open the bank account and extend in Thailand.
