Hi,

Many Holocaust related records in France are held at the departmental archives, not local archives.  Nice is in the Alpes-Maritime department, and their archive's website is https://www.departement06.fr/culture/archives-departementales-2797.html.

However, since Nice is a large city, you should also check with the city archive, https://archives.nicecotedazur.org/.  Both websites are in French.

USHMM has selected records from the Alpes-Maritime departmental archives.  I checked the finding aid.  We do not have the Police d'Estrangers records.
