With the evolution of the migratory phenomenon and the main theories on the subject, it is important to analyze the concept of social networks and their impact on the quality of life of migrants, on strengthening the sense of belonging to the community of origin, as well as on the dynamics of cohesion and integration, which are developing thanks to technologies, in the community where migrants arrive. The loss of relevance regarding the territorial aspect and the possibility of traveling with mind and body, make it useful to approach the "migration problem" not so much at a purely geographical level, but precisely at a relational level, giving importance to the nature of the social spaces in which migrants interact, spaces that cross international borders . Therefore, transnationalism is an essential phenomenon for understanding the contemporary world. For this reason, we will analyze this concept, with the aim of capturing what is the emblem of the rebirth of the community spirit today, of the diasporic community, which is not linked to places crossed and remembered, but to the flows of people, things and information. The analysis will be carried out on the assumption that these communities can be described as the mirror of the two conditions typical of contemporaneity: simultaneity and mobility. Thus, the emphasis will be placed on the sense of belonging and on the impact of the new means of communication, on the aggregation opportunities of migrants, as a response to the belief that the analysis of the use of social networks should be placed in the background compared to the analysis of more subjective, more difficult phenomena understandable and measurable, but which represents the essence of the interpretation of contemporary migrations, especially in the understanding of the opportunities that open up, thanks to digital technologies.
