This chapter explores the contextual layers associated with emerging adult international students during their university-to-work transition. First, the authors examine the term, emerging adulthood, to consider the relevance for use with international students. Next, they discuss cultural identity development theories that can be applied to international students. Included is a look at how popular dualistic theories that position Western cultures as primarily individualistic and Eastern cultures as collectivist may be no longer relevant. Further, they explore theories that provide evidence that social identity is fluid and contingent on comparisons to both in-groups and out-groups. Thus, each time an international student finds themselves in a new context with different people, they need to renegotiate their identities and their sense of belonging. In this exploration, the authors also delve into how social capital theory—the benefit one derives from belonging to social groups, networks, or institutions—may be conceptualized with international students, and they show how social support and social capital are closely intertwined. In discussing the importance of personal ties, such as family and friends, they explore the nuances of local and home support. Regarding institutional support, they discuss the critical importance of university faculty and supervisors in becoming a new source of social capital and in creating new bridging relationships and social networks in the destination country. Through our examination of international students’ university-to-career transition, the authors broaden and deepen the current understanding by unpacking the contextual layers of emerging adulthood, identity development, social relationships, and social capital.
