The work of HEKS/EPER revolves around socially disadvantaged people. These include asylum seekers and refugees, sans-papiers (undocumented persons) as well as people on low incomes and those facing discrimination. They are all especially at risk of seeing their rights violated or of social exclusion. HEKS/EPER advocates on their behalf and strives to support them in exercising their rights and improving their lot. HEKS/EPER works actively to secure Switzerland's protection for people who would be in danger if they returned to their country of origin or to a third country, whether for medical reasons, owing to violence and war, the lack of a social security network or because of deliberate persecution.
