This qualitative study is designed to understand the complex reality of the field for immigrant workers, focused on the practitioner\'s experience and its implication for social welfare education. The nature of the field is composed of the reality of the field\'s interactions with immigrant workers, employers, community, and government. It includes the practitioner\'s experience with \'empathy, respect, understanding, cultural diversity\', through a process of \'person-to-person based human contact\' and \'story-telling,\' and the practitioner\'s role in a community level to prepare the next generation for the muticultural society. Despite the vision of social activism considered as the NGO\'s unique identity, the practitioner suffers from lack of \'professionalism\' and \'reeducation opportunities\' in the field. Further suggestions include social welfare eduction of which target populations should include the practitioner, the immigrant worker, the employer, and the community, and the development of the field education dealing with immigrant workers and the perspective of social welfare movement in Korea.
