Never having done this before, I just got a new UK Passport with a new Non O visa in (Married to a Thai , my age 50)

I understand I will have to show 400k in the bank for two months

Ive had more than this in my Bangkok and Kasikorn account for years, do I have to show the money came in form OUTSIDE of Thailand?

When exactly can i start the extension of stay, can I do it on the first 90 day segment of my NON O Visa or do I have to wait until the last of my 90 day entry exits?

Thanks In Advance

You do not need prove the money came from abroad. The account must be in your name only,

You can apply for the extension of stay based upon marriage during the last 30 days of any of the 90 day entries from your visa. You do not have to wait for your visa to expire,
