I have meet a couple of foreigners living in Peru who say that they qualified for the "Familiar Residente" Visa without being married. They lived with and continue to live with their partners.
In Peru, this is referred to as "convivientes" and is quite common amongst Peruvians. I know several people whose parents never married.
Anyone have any details on this? What documents would be needed to proof that my girlfriend and I have been living together?
