Copia nitida do passaporte

hello , I need to know what do they mean by copia nitida do passaporte , is it a just clear copies

or authenticated copies done at the cartorio ?

Well, if you need those copies for a VISA request you'll need a clear authenticated copy of your passport, including blank pages.

well , I actually  need the copias nitidas to apply for a VIPER visa .

do you know if I need to take an appointment through web site of policia federal

or  just go there any day , to apply for the permanent visa ?

Regards
