Unfortunately that visa did not live up to the expectations of the BOI or thailand and I think world wide they've sold like 4000 or so since it started 😮 and almost ALL of those have been the wealthy pensioner category.
That doesn't mean it is a bad visa to get, just didn't sell well
Totally works exactly like they sell it, You apply using the BOI website, you get approved, you show up there and they ink in a visa good for 10 years with a admitted until stamp good for 5 and a multiple re-entry permit good for 5..
NO ONE knows what happens when that 5 year stamp runs out because the visa hasn't ran long enough.
No problem applying on an OA visa/entry or extension. You MIGHT have to exit/re-enter to get OFF that OA and on to a free entry stamp to get the visa inked in here at Cham Churi Square LTR headquarters in Bangkok. <- BUT I don't know honestly
I do know of 20-30 people who went from "retirement visa" to the LTR wealthy pensioner visa but I don't know anyone who did it from an OA
On their website they have "authorized agents" contact them OR email LTR directly and see what they say
