Kwon explores how Korea's two major religious groups, Buddhists and Protestants, have emigrated and how their religious beliefs affect their adjustments after immigration. Kwon bases his study on a survey of 114 Korean congregations, participatory observation of a Buddhist temple and a Protestant church, and in-depth interviews with 109 devout immigrants. He finds that non-religious variables-urban background, educational level, and social class-have a greater effect on adjustment to the host society than religion does. Religious congregations promote members' social capital for adjustment, but at the same religious participation serves as a barrier to assimilation.
