The '60 day' he mentions, he specifically describes as an extension, he never mentions it as being a non O, not even in the quote you type under, misrepresenting his words, he correctly refers to it as an extension in that quote in relationship to the Non O visa single entry, which he correctly attributes the correct nomenclature to it.
He states,
"We can get a 60 day *extension* on the "Single-entry Non O based on marriage" for "visiting Thai spouse"
He then asks,
"My question is, can I get the one year "Non O based on marriage" extension whilst I am here on the 60 day extension to visit Thai spouse?"
To which your answer should be, yes, (as mine would be because ive done this countless times) though you choose quite consciously, like many asean now cave dwellers on here, the high pompous road, through your explanation of repeating back to him what he asked of you. Yet, with the incorrect assertion you made, that he, not you, had confused and conflated wrongly the extension and the non O.
He does indeed state 1 year extension with the parenthesis of relating it to the visa it is associated with, and instead of using brackets he uses quotation marks, but again thats not your quibble, its something to do with 60 days something or other...??..? Which clearly is an aberration of your mind, rather than real world events recorded that we minions under your rule can observe.
Extensions are relative to their visa types, how do i know this, ive done many in almost 20 years ive been here and ive heard many authorities in immigration use this description of them, not least on their websites and because even they themselves get it wrong as professionals in the field. Where extensions are described, exactly as this gentleman had done so, with relationship to its visa that one is extending the permission of stay based upon, that criteria for applying for how it is regulated and what criteria must be presented.
Eg. Can i get an extension relating to my visa non O that i would be applying for if instead i use business visa criteria? No. They are different. Ergo, the need for specificity in description of the relevant visa one wishes to extend, in asking a question about its constituent extension.
Which by any young persons eyes and acuity, like my own, could tell, seems to be this constant attempt by many 'long standing members' on here to tell those seeking reasonable advice on state regulated obfuscated rules of law, the difference between a visa, an extension, and on, so much so, you see things that arent even there, just so you can point them out in your self appointed post no one cares for.
You and many other high priests on here, (unlike other gentleman dearly missed) get push back and scorn all the time for this irreverant behaviour, and yet, you persist, and we should not be surprised, as you well know, you cant teach an old... farang civil restraint when scoring vacuous points on a forum they hold court in, its far more approriate to this ignominious old /new gaurd protecting the sacred secrets of immigration nomenclature regarding visas and extensions from unholy exageration or misuse... as if it matters, or has ever mattered 1 bit.
