International immigration law serves as a fundamental framework for regulating the movement of individuals across borders while ensuring the protection of migrants’ human rights. This study provides a comprehensive analysis of the main principles, challenges, and contemporary developments in international immigration law. Using a qualitative research approach, the study examines primary legal instruments, international treaties, national legislation, and secondary literature to evaluate compliance, enforcement, and emerging issues in migration governance. Findings reveal significant disparities in the implementation of international legal norms across countries, with developed states demonstrating effective mechanisms, while developing nations face structural and resource constraints. The study highlights persistent gaps between international obligations and domestic enforcement, particularly in addressing irregular migration, human trafficking, and climate-induced displacement. The results emphasize the importance of international cooperation, policy harmonization, and legal reforms to ensure equitable and effective migration management worldwide.
