Czech Republic and Poland. Neighboring countries, geographically, culturally and linguistically close, partially sharing their historical destiny. Currently they do not represent the mutually most important destinations from the point of view of migration. And yet, after 2004, when both countries joined the European Union, they became a temporary or permanent second home for several hundred young people, so-called white-collar workers, performing mental jobs, most often in international corporations, but also working, for example, at universities or as translators. Migrants perform transnational practices, fulfill their needs and play social roles in the country of origin as well as in the destination country. This is made possible by the proximity of the countries and the possibilities offered by modern technologies, especially social networks and communication applications. Mobile actors are representatives of alienation and vectors of transculturation for both societies, the one from which they leave and the one to which they come, as also the destinies "culturally close" migrants, moving voluntarily, tend to be complicated, and integration into mainstream society is often more difficult for them than these migrants themselves originally assumed.
