Well,
@Ba***
I think you have your answer(s).
And seeing as you never mentioned which of the 70+ immigration offices you go to, I don't know how anyone can pin it down for you. :/
It's totally going to be between you and the immigration office if they come and do a home visit when you apply for a yearly extension based on marriage to a thai during the under consideration period.
Certainly you should ask your immigration officer when you apply for the extension if they're comin' out or not.
