International Covenant on Civil and Political Rights
Individual liberties

Article 12 guarantees freedom of movement, including the right of persons to choose their residence, to leave and return to a country. These rights apply to legal aliens as well as citizens of a state, and can be restricted only where necessary to protect national security, public order or health, and the rights and freedoms of others. The article also recognises a right of people to enter their own country: the right of return. The Human Rights Committee interprets this right broadly as applying not just to citizens, but also to those stripped of or denied their nationality. They also regard it as near-absolute; "there are few, if any, circumstances in which deprivation of the right to enter one's own country could be reasonable".
