Can I apply for a retirement visa extension with 11 months left on my passport?

The user inquires about the acceptability of applying for a retirement visa extension in Thailand with 11 months remaining on their British passport, as they plan to renew it shortly. The response highlights that having 6 months left is generally required, but applying for an extension less than 12 months before the passport expires means the extension will be limited to the passport's expiration date, resulting in a loss of the unused time. The user acknowledges this advice and states they will adjust their future application timing.
