Abstract: The legal grounds for acquisition and revocation of citizenship by persons born and residing on the territory of different states may differ significantly due to historical, political, economic, and other reasons. This article provides a comprehensive analysis of the grounds for revocation of citizenship – denaturalization. The author establishes the factors and circumstances that contribute to termination of the political0legal ties of an individual with the state upon the initiative of the state. The article explores the international legal acts, as well as conducts a comparative analysis of the legislation of different countries on the issues of denaturalization. The author reviews the conditions and restrictions for implementation of the procedure for revocation of citizenship by the state, as well as correlation of such grounds for termination of citizenship as revocation of citizenship and reversal of decision on naturalization. The scientific novelty lies in the conclusion that revocation of citizenship is not prohibited by the international legal acts if there are legal grounds established by the domestic legislation of the country. Such grounds may include unlawful actions of a citizen against public security and national interests, as well as other actions that undermine the fundamentals of the constitutional system. The author offers the open legislative consolidation of the legal institution of denaturalization for the possibility of revocation of citizenship of an individual upon the initiative of the state.
