Your posts regarding terms visa , extension etc are all over the shop.
When someone starts a thread on AseanNow now with statement such as ...." I have a marriage visa" and then proceed to post a question, anyone reading has no idea what they mean.
In my mind they could have a
1. Non O based on marriage.
2. ME Non O marriage.
3. An extension from a Non O based on marriage.
The first is a single entry visa that gives a 90 day permission of stay.
The second is a multiple entry visa valid for one year it gives stays of 90 days then you need to exit Thailand (unless you obtain an extension)
The third is an Extension of stay from a non O giving permission of stay of one year.
Visa is very different to Extension.
Forget English definitions.
VISA EXTENSION which is a term used even by immigration and is on their walls in offices is short hand type. No such thing animal.
The same goes for Retirement.
The expression "I have a Retirement Visa" tells very little.
Could be a valid non O-A.
Could be a non O based on retirement.
Could be an extension based on retirement.
Could even be ME Non O retirement which is a multiple entry visa valid for 12 months based on retirement (not available in many countries)
