Just go to your local Immigration office once you get here (with your No O obtained from overseas) and ask them what their requirements are for an extension. The requirements vary from office to office.
Although, my post is not about a DTV extension, a Non O Retirement extension (at least the first one) is now a 7 week process here, involving 3 trips to Immiโฆ
No, that is not true. For an extension of the 3 month non O to a 12 month Retirement Visa, the 800,000B needs to be seasoned in a Thai ๐น๐ญ Bank account for two months prior to extension. That is the requirement of Thai Immigration.
There have been reports of a Rouge Bank Manager somewhere, asking for funds to be seasoned for 4 months but this has not been confirmed and would also go against The Dept of Immigration rules.
