This article deals with the origin and trajectory of the passport, its multifaceted nature in modern life. Firstly, a passport is a standardizedand written, visualized, and anthropometric, personalized proof of citizenship of its bearer, but not always. Secondly, it is aproof of identification, regardless of the time, place, and mode of acquisition of citizenship of a particular state (in the form of personaldata processing) and control over them by that state. Finally, it is a paper document (actually machine-readable) that gives its bearerrights, responsibilities, and privileges guarantee his/her freedom of movement (unlimited and indefinite entry into and exit from thestate of citizenship) and immunity (from extradition and expulsion).In the time of globalization and omnipresent migration, there is a myriad of modern researches worldwide related to passport,citizenship, person identification, etc. Up to my mind, we can shortlist such authors as Atossa Araxia Abrahamian (cosmopolites andglobal citizen), Leo Benedictus (history of the passport), Claire Benoit (the passport in the context of citizenship), Evelyn Capassakis(passport revocations or denials), Jelena Džankić (the global market for investor citizenship), Yossi Harpaz (dual nationality as a worldwideasset), Martin Lloyd and Craig Robertson (the history of the passport), Mark B Salter (the passport in international relations),Ayelet Shachar (the shifting border of immigration regulation), Peter J Spiro (the past and future of dual citizenship), John C Torpey(the invention of the passport), James Tully (on global citizenship), Patrick Weil (citizenship, passports, and the legal identity of persons).In modern days this most traveled document in the world is a perfect political and legal instrument used by the particular stateto identify its citizens, keep them in the borders, and not let them enjoy the freedom of movement extra territory.
