This study examines service integration and case management practices for economic migrants, refugees, asylum-seekers, and returnees, focusing on examples from seven countries. It analyzes these interventions across eleven dimensions, comparing approaches in Bangladesh, Colombia, Italy, Kosovo, Lithuania, Türkiye, and Romania and highlighting successes and challenges. The findings show that effective models emphasize collaboration between governments, NGOs, and multilateral organizations, foster integration between migrants and native populations, and have the potential to yield economic benefits. However, limitations include persistent gaps between needs and services, inconsistent follow-up, and reliance on short-term funding. The study underscores the importance of a holistic, long-term vision, including robust monitoring and culturally sensitive approaches, to maximize the effectiveness of case management for people on the move
