Replace whatever is behind the person with a plain colour, the way document photos require.

Document photos almost always specify a plain, light, uniform background, and a photo taken at home almost never has one. Cutting the background out and replacing it with plain white or light grey satisfies that specific requirement. It satisfies only that one. Document photos also fix the print size, the proportion of the frame the head must occupy, the expression, whether glasses or head coverings are allowed, and how recent the photo must be — rules that vary by country and by document, and that a background tool has no view of. So use this for the background, then check the size and framing against the authority's own published rules before you submit anything. The passport photo tool crops to the standard document sizes and is the better starting point when the print size matters.
It handles the background rule only. Size, head proportion, expression and recency are set by the issuing authority and have to be checked against their own published rules.
Most ask for plain white or a light neutral, but the exact requirement varies by country and document. Check the rule before choosing.
Use the passport photo tool, which crops to the standard document sizes rather than only changing the background.
