According to international conventions, everyone can leave his or her country and choose a country in which he or she wishes to live. This opportunity, however, raises some doubts. Are emigrants’ rights to choose their own state accompanied by the state’s obligation to accept them? Do the hosts have any duties with respect to strangers? To what conclusions does the dialectic of mutual rights lead in this regard? How does one resolve the conflict of conflicting values, interests and emotions felt by free individuals on both sides of the border? The author searches for answers to these questions from the perspective of the individual perspective. She refers to Robert Nozick’s concept of liberal utopia as being representative of individualism. This allows for the formulation of two conditions of citizenship as pre-selection criteria for immigrants.
