The article presents the results of a comprehensive study of digital technologies in the field of migration control in the context of international law using the examples of Ukraine, Poland, and the United Kingdom (UK). The aim of the study is to comprehensively assess the level of digital integrity and legal balance of migration control systems in Ukraine, Poland, and the UK based on the integration of technical, ethical, legal, and humanitarian parameters using the author’s Migration Digital Integrity Index (MDII). The methodological architecture combines comparative legal, statistical, and modelling approaches using Delphi survey, analytical hierarchy process (AHP), correlation and regression analyses (Pearson, Spearman), bootstrap estimation (n = 1000), k-means clustering, and PCA visualization. The results showed that the UK achieves the highest rate of digital integrity (MDII = 0.83) thanks to the legal-by-design legal model, Poland (MDII = 0.77) forms a balanced technological and humanitarian system, and Ukraine (MDII = 0.70) is characterized by high digital activity with lower legal stability. The academic novelty is the creation of a multidimensional tool for quantitative assessment of the legal balance of digital migration control systems. The practical value is identified areas for harmonizing the Ukrainian model with the European standards eIDAS 2.0, GDPR, and OECD Digital Government Framework in order to increase the legitimacy, efficiency, and ethics of migration governance.
