I would think even one office visit per week is too many
If "office visit" means "sent to the office as a disciplinary measure," then I would agree. But my DD, for example, is always allowed to go to the office instead of to the noisy area where the children line up before school, and she joins her class as they go by the office on the way to the classroom. She is also allowed to go to the office instead if assemblies are intolerably noisy. So she has multiple office visits per day, but they are part of her accommodations, and I'm fine with that.
