Graham Seal
Graham, you are unfortunately mistaken. The 40,000 THB monthly income method is still very much a valid option for Non-O (Marriage) visa extensions according to the official regulations.
The Facts:
The legal basis is found in Royal Thai Police Order No.
********
, under section 2.18. It explicitly states that the applicant must meet ONE of the following financial criteria:
A security deposit of at least 400,000 THB in a Thai bank.
OR an average monthly income of at least 40,000 THB.
Why you might be confused:
The reason some people think it’s "gone" is that several embassies (like the UK, USA, and Sweden) stopped issuing Income Affidavits.
Because of this, the proof is now strictly on the applicant to show 12 months of Thai bank statements clearly displaying monthly transfers from abroad. The method is NOT disallowed for new applications; it just requires a different type of proof (bank book records instead of an embassy letter).
You can find the official criteria here:
Order of the Royal Thai Police No.
