The paper provides a theoretical foundation to address the question whether it is possible to become a transnational migrant while using Internet resources, i.e. to be a transnational migrant yet not to cross national borders. The author puts forward the arguments clarifying the essence of the question and outlines possible answers to it. The paper starts with a review of definition of transnationalism, updates the notion of transnational migration and outlines the importance of online technologies for dynamics of transnationalism. The author defines and distinguishes the following concepts: “internet”, “world wide web”, “cyber” “virtual”, “online”, and “offline”. Based on A. Filippov's sociology of space, the author provides three answers to the question of whether internet is a space: 1) Internet is not spatially organized, however, space could be thematized in the internet; 2) There are specific spaces of interaction in the internet; (3) Internet is a space constituted by online routes. In concluding part of the paper, two types of online transnationalism are proposed: ‘routing transnationalism' and ‘transnationalism of interaction spots'. The author concludes that these two types have to be viewed as ideal types of transnationalism
