Repatriation is the process of returning a person - voluntarily - to his or her place of origin or citizenship. This includes the process of returning military personnel to their place of origin following a war. It also applies to diplomatic envoys, international officials as well as expatriates and migrants in time of international crisis. For refugees, asylum seekers and illegal migrants, repatriation can mean either voluntary return or deportation.
The term may also refer to non-human entities, such as converting a foreign currency into the currency of one's own country.
Voluntary repatriation or voluntary return is the return of eligible persons, such as refugees, to their country of origin or citizenship on the basis of freely expressed willingness to such return. Voluntary repatriation, unlike expulsion and deportation, which are actions of sovereign states, is defined as a personal right under specific conditions described in various international instruments, such as the Geneva Convention and Protocols, along with customary international law.
As repatriation can be voluntary or forced the term is also used as an euphemism for deportation. Involuntary or forced repatriation is the return of refugees, prisoners of war, or civil detainees to their country of origin under circumstances that leave no other viable alternatives. According to contemporary international law, prisoners of war, civil detainees, or refugees refusing repatriation, particularly if motivated by fears of political persecution in their own country, should be protected from refoulement and given, if possible, temporary or permanent asylum. The forced return of people to countries where they would face persecution is more specifically known as refoulement, which is against international law.
