The processes of post-socialist transformation, especially large-scale migration from Eastern Europe to the Western hemisphere, are creating an ‘expansion of space’ from the local to the supra-local. This process involves the expansion of personal-, familial- and friendship-based networking practices which acquire significance as transnational mobile livelihoods and as significant dimensions of urban dynamics in global cities like Chicago. What are the networks, attachments and social bonds of Eastern European migrants in Chicago? Ethnographic fieldwork conducted in Chicago in 2013 among recent Lithuanian immigrants brought out the importance of a cultural identity of East European-ness involving contested loyalties and limited integration. While living locally, Lithuanian immigrants are expected both to be bound to the ethnic community and to be immersed in the multicultural life-style of the mega city. However the research has shown that livelihoods and social relations among ‘one's own people’ are involved in trans-ethnic networks and that the bonds of intimacy and the alliances among ‘one's own people’ run through homeland roots and patrimonial linkages rather than through the citizenship loyalties of the state (the United States and/or Lithuania). The circle of ‘one's own people’ implies extensive reciprocity and social networking among ‘friends’ and co-workers based on ‘one's own resourcefulness’ a kind of social capital. Thus, ‘sharing important acquaintances’ ought to involve ‘doing favours’ and livelihood experiences transplanted from oversees are practised in Chicago as ‘local’ life-styles and are used for transnational networking, securing in the process the social status of those involved.
