We get a LOT of posts about what's required for a "marriage visa renewal" or a "retirement visa renewal" which is a way people ask for what does their immigration office require to get a new yearly extension of stay.
The reason we say go to your office, get the hand out and talk to them about what you need is not because we don't want to provide information, but because we don't want to provide the wrong information.
There are OVER 70 immigration offices in the country and sadly for us most of them do things their own way. There is very little across the board consistency between them.
What might work at one, won't at another, what's required at another might not be required at yours. It's just TOO hard to list every permutation of what's required at your office.
That's also why we say post on a f/b page related to where you live. I'd bet dollars to durian you're not the only foreigner in that province who has gone for an extension at that immigration office.
BTW: this is the same reason we tell people wanting 60 day covid extensions to go and ask OR post on a f/b page related to where they live.
Good Luck to each and every one of you, take care, stay safe
