This paper examines the role of four types of influences on the Subjective Well-Being of Nigerian self-initiated expatriates in Germany: (1) Individual, (2) Group, (3) Social, and (4) Organizational. Based on survey data from 377 respondents, we find that variables in all four categories influence subjective well-being. Our findings generally agree with the results predicted by the theory, albeit a few counter-intuitive findings. Above all, our results indicate the potency of social-and group-level influences. The individual-and organizational-level influences, too, are significant, although to a slightly lesser extent.Overall, our results suggest that "soft" factors play an important role in augmenting perceptions about one's own well-being in the context of international assignments.
