There it comes out.
You make one giant mix from different visa's, different extensions, different ways of entry.
Please read the website of the Thai Embassy where you are residing about the
Non Immigrant O visa based on being over 50 years of age
Non Immigrant O visa based on being a dependent
Non Immigrant O-A (Long stay)
Visa Exempt Entry
Tourist visa
All different things and you mix all the different requirements.
