 In response, the US government passed the Expatriation Act of 1868 and concluded various treaties, the Bancroft Treaties, recognizing the right to renounce one's citizenship.The Universal Declaration of Human Rights lists both the right to leave any country, including one's own (Article 13(2)), and the right to change one's nationality (Article 15(2)), which implicitly recognizes the right to renounce citizenship.Renunciation of citizenship is particularly relevant in cases of multiple citizenship, given that additional citizenships may be acquired automatically and may be undesirable.
