This paper theoretically covers concepts of migration and mental health, as well as the possibilities of social work within that area. Migration is known even in the distant history of mankind, but only relatively recent mass migration processes have prompted scientists to intensively study the impact of migration on the mental health of migrants. Various studies prove that the migration process can have an intense impact on the mental health of migrants, mostly creating challenging mental health difficulties such as depression and various anxiety disorders. Development of mental disorders is influenced by the existence of various factors most often categorized as individual, social and economic, and environmental. Social work operates on the principles of social justice, human rights, collective responsibility and respect for diversity, promotes social change and social cohesion, and empowers individuals to overcome life's challenges and increase well-being. Therefore, it can undoubtedly contribute to mitigating the consequences of migration and the transit period of migrants adapting to the new environment.
