The phenomenon of migration poses a pressing quandary within the context of the global legal framework, heightened by persistent political instability and the repercussions of climate change. These factors compel a significant populace to seek alternative habitats, where they encounter varying degrees of success in the process of societal integration. The purpose of the article was to explore the legal aspects of migration processes in the modern world viewed through the lens of delineating the rights of refugees and migrants. With the use of rigorous scientific methods such as content analysis and comparison, this study elucidated the fundamental aspects of the migration dilemma. It demonstrated that the development of sound migration policies is of paramount importance in navigating this complex terrain. While initial international resolutions made general declarations, contemporary conventions provide detailed frameworks that, alongside national laws, establish the foundation for the assimilation of non-citizens into host societies. It was demonstrated that the increase in the number of migrants and displaced persons has led to a more detailed legal framework. While the initial international resolutions, such as those from the United Nations, primarily took a declarative stance, contemporary conventions exhibit a significantly more detailed approach. In conjunction with the legal norms of individual nations, these modern frameworks establish the foundation for the assimilation of recently arrived non-citizens into their host society. The results pointed out that this process took place according to the scheme of considering international standards and conventions on the migrants' and refugees' rights protection, which become the basis for the development of relevant provisions of national legislation. Consequently, in order to address migration comprehensively, the findings underscored the need to promote inter-state legal cooperation. The global community can progress towards achieving a fairer and more sustainable resolution of migration challenges by embracing a framework centered on inter-state legal cooperation. In addition to highlighting the current state of the law, the study argued for the development of innovative solutions to address the complexity of migration in the interconnected world.
