Physical process of changing visa at the immigration office?

Im doing it for the first time next week.
Im changing to a spouse visa at Tachikawa.
So as far as i know, i turn up, wait my turn to be let in, then wait a little longer and get called.
At this point i hand them everything already filled out. Then they review it.
Thats it?
I read somewhere that they question you on a few things like my address. I just moved 2 weeks ago so hope i don’t fuck that up lol.

Thanks. Would be great to hear experiences. My Japanese is only N3 and although my wife is native i dont want to have a bad impression.
