The article presents selected results of preliminary research regarding the life situation of Polish migrants living in London in the face of Brexit. The aim of the study was, among others, to analyze readaptation strategies in a group of Polish migrants in the conditions of the forthcoming geopolitical change, i.e. the UK’s exit from the European Union. The theoretical basis for the study was the concept of social anchoring. In the context of analyzing readaptation strategies in the conditions of migration, the concept can explain processes that stabilize the position of people in the face of social change, but also in a generally understood, rapidly changing society. At the same time, it can explain the implementation of specific adaptation strategies. Research results indicate that there is a relationship between the number and subjectively perceived ‘importance’ of social anchors, and adopted readaptation strategies in the face of Brexit. Issues related to economic and institutional and legal aspects turned out to be important anchors. I have also noted four types of ‘behavior’ that can be called readaptation strategies. They were called: strategy of citizenship, strategy of suspension (“Brexit numbness”), strategy of return and strategy of confidence. The research was carried out using a qualitative approach on a group of 25 Poles living in London. Interviews were conducted at the turn of April and May and in October 2019 as part of a scientific project: “Process of social (re)adaptation of Polish migrants in London in the face of Brexit – changing and redefining social status from an intragroup perspective” (NSC, Miniatura 2, Nr rej.: 2018/02/X/HS6/02300).
