Just so we're totally clear IF it was not mentioned in this police order it means the rules didn't change for the extension or method to get the extension
Just to summarize the new Police Order:
NO changes for application of a VISA at a Thai Consulate or Embassy
NO changes for foreign women married to Thai men
NO changes for people using the banked money, 800K baht for being over 50 years of age or 400K baht for foreign men married to Thai women.
NO changes if you Embassy still hand out the Income affidavit.
Changes for as far as we know for citizens of 4 countries, these are UK, USA, Australia and Denmark, just because these people can not get an income affidavit of their Embassy.
NO changes if used banked money method for proof of funds
BUT
Using monthly income method you MUST show:
Minimum 65K baht deposits from foreign country into their Thai bank account if over 50 years of age
Minimum 40K baht deposits from foreign country into their Thai bank account if married to a thai
These deposits have to be done 12 months, every month prior the application date.
