The objective of this study is to present the opinions of Ukrainian secondary school students, living in a boarding school in Lublin, on their adaptation to the new environment while studying in Poland. The questionnaire method was used, which offered an insight into particular aspects of adaptation for their studying abroad, e.g., coping with being parted from their family, managing free time, adjusting to the new educational environment, viewing the Polish society, as well as observing differences and similarities between the Polish and Ukrainian culture. The collected data point to a need to intensify educational activity promoting the space of mutual understanding between the citizens of the neighbouring countries. The problems revealed in this study show that the educational migration of Ukrainian students to Poland requires implementing a long-term and systemic educational policy that would shape multicultural competence of the Polish society.
