This article aims to contribute to the ongoing debate on the concept of a group as it is understood within the social sciences. The paper investigates how the living conditions created by organizations influence mutual relationships among Czech and Slovak migrants in London. Concerning particular way of accommodation (share houses) and virtual space, it is argued that organizations play a significant role in the constitution of a common 'Czecho-Slovakian' community through their marketing strategies. Sharing living and working spaces, Czechs and Slovaks have an opportunity to know each other and to establish close relationships without accentuating their ethnic affiliation. Although in the certain situations the ethnic schema is activated, the authoress of the study suggests that the life style of the migrants plays more significant role then their ethnic belonging in the formation of the personal relationships.
