This paper discuss about the influx policy that should be taken by the government. Project-induced-in-migration (or influx) is the movement of people from area outside project-impacted zone to the project-impacted zone. The aim of it is to find economic opportunities and improving quality of their life. Aldi et al. (2013) stated that the influx has many negative effects especially for the social and environmental aspects in the mining project areas and its surrounding.The three main negative effect that are materialized, (i) The increasing of crime rate; (ii) the marginalization of indigenous people by the immigrant communities; and (iii) the decreasing of public health quality since the mining operation. Three important actors in development, which are the government as policy makers, the companies as capital modals, and society as the object who affected both directly or indirectly; each of them has their own role play and perception of influx. They also have own solution to cope with the impact of influx in the project areas. Their role, influence and relation will be reviewed and analyzed with the concept of sustainable livelihood framework.There are five capitals within concept of livelihood assets, which are, (1) Human capital; (2) social capital; (3) natural capital; (4) physical capital; and (5) financial capital. By taking the study cases from Weda Bay Nickel in Eastern Indonesia, this paper found that the main development goals for all of the development actors are to achieve sustainable development. Unfortunately, technological development in the mining enterprise is leading discrimination and huge gap between immigrant workers and local communities in managing and accessing their assets. The government as a policy maker tends to prioritize the companies as the capital modals.Therefore the process in achieving the sustainable development goals was blurred. Based on the sustainable livelihood approaches, this paper discuss about how do the local communities strengthen their potential aspects to reduce the negative impacts of influx. They also need to compromise in how to focus on their potential assets and cover the underperformance from the other stakeholders. It expected to provide a new integrated approach for influx-migration policymakers, especially in mining industry areas
