it’s the same as the retirement visa requirement 800k/65k per month but if you are married to a Thai it’s 400k/40k per month. Many expats married to Thais use the 40 K per month to satisfy the requirement. FYI they will all except an income affidavit from your embassy if can get one. US, UK, AUS embassy will not give one.
not unless you can come up with 800,000 and leave it in the bank untouched since you will not be able to qualify for a monthly deposit of 65k per month
