and this is why you don't believe ANYTHING from a thai consulate/embassy about what you can do INSIDE the country
No matter what that embassy said you cannot get a 90 day non-O visa inside the country based on trailing spouse when your husband has a retirement extension.
It is not a reason they offer that visa for inside the country.
Embassy/Consulates OUTSIDE thailand sell visas and are run by the Ministry of Foreign Affairs Office
Thai Immigration offices INSIDE the country sell visas/extensions and are run by the Immigration Division of the Royal Thai Police.
Those are two completely different offices that have nothing to do with each other.
