Unpaid people who belong to a parish or religious community and who help welcome the beneficiaries of the Humanitarian Corridors program. Volunteers agree to collaborate with the social workers of the diocesan Caritas unit and with the mentor family to provide all necessary forms of support to the beneficiaries. This may include helping a beneficiary learn Italian, accompanying a beneficiary to public offices, supermarkets, schools, and helping a beneficiary search for job opportunities.
One particular category of volunteers are the so-called "civil service" volunteers: young people under 30 who are participating in the national program of civil service and who have chosen to fulfill their duty by supporting the social workers in the year-long Humanitarian Corridors program at a diocesan Caritas unit.
