For a type O extension based on marriage, I have seen on this site members referring to a document from the local Ampour confirming you are still married. Is there a Thai name for this document? Indeed is it a requirement at CW
TLDR : Answer Summary
The user inquires about a specific document required for extending a type O visa based on marriage in Thailand, particularly asking for the Thai name of the document that confirms marriage status issued by the local Ampour.
