I like these visa threads so much different opinion
When I was in Nong Khai( Marriage visa O ) I needed to report to that office which I did.
When we was in Jomtien I was told I needed prove of address to do the 90 day report there which I did.
I think the bottom line is things do vary from one office to another and sometimes even one immigration officer to another.
I found advice such as the O.P is requesting best sourced at the place you intend on signing.
