JRS Cambodia operates a welcome centre in Phnom Penh, accompanying and serving urban refugees and members of the Montagnard ethnic group through social assistance and education. JRS Cambodia advocates for stateless people as well, assisting with the attainment of documents and education.

JRS Cambodia publishes research on relevant issues concerning refugees, and coordinates with the Metta Karuna reflection centre in Siem Reap, where visitors can come to heal and raise awareness about the struggles they face in a safe, interfaith environment. Each year, JRS Cambodia organizes a regional workshop at the centre.
