Assimilation - Adaptation of one ethnic or social group β usually a minority β to another. Assimilation involves the subsuming of language, traditions, values, mores and behaviour or even fundamental vital interests. Although the traditional cultural practices of the group are unlikely to be completely abandoned, on the whole assimilation will lead one group to be socially indistinguishable from other members of the society. Assimilation is the most extreme form of acculturation.
Asylum seeker - A person who seeks safety from persecution or serious harm in a country other than his or her own and awaits a decision on the application for refugee status under relevant international and national instruments. In case of a negative decision, the person must leave the country and may be expelled, as may any non-national in an irregular or unlawful situation, unless permission to stay is provided on humanitarian or other related grounds.
Border management - Facilitation of authorized flows of persons, including business people, tourists, migrants and refugees, across a border and the detection and prevention of irregular entry of non-nationals into a given country. Measures to manage borders include the imposition by States of visa requirements, carrier sanctions against transportation companies bringing irregular migrants to the territory, and interdiction at sea. International standards require a balancing between facilitating the entry of legitimate travellers and preventing that of travellers entering for inappropriate reasons or with invalid documentation.
Brain drain - Emigration of trained and talented individuals from the country of origin to another country resulting in a depletion of skills resources in the former.
Brain gain - Immigration of trained and talented individuals into the destination country. Also called βreverse brain drainβ.
Circular migration - The fluid movement of people between countries, including temporary or long-term movement which may be beneficial to all involved, if occurring voluntarily and linked to the labour needs of countries of origin and destination.
Country of origin - The country that is a source of migratory flows (regular or irregular).
Emigration - The act of departing or exiting from one State with a view to settling in another.
Facilitated migration - Fostering or encouraging of regular migration by making travel easier and more convenient. This may take the form of a streamlined visa application process, or efficient and well-staffed passenger inspection procedures.
Forced migration - A migratory movement in which an element of coercion exists, including threats to life and livelihood, whether arising from natural or man-made causes (e.g. movements of refugees and internally displaced persons as well as people displaced by natural or environmental disasters, chemical or nuclear disasters, famine, or development projects).
Freedom of movement - A human right comprising three basic elements: freedom of movement within the territory of a country (Art. 13(1), Universal Declaration of Human Rights, 1948: βEveryone has the right to freedom of movement and residence within the borders of each state.β), the right to leave any country and the right to return to his or her own country (Art. 13(2), Universal Declaration of Human Rights, 1948: βEveryone has the right to leave any country, including his own, and to return to his country. See also Art. 12, International Covenant on Civil and Political Rights. Freedom of movement is also referred to in the context of freedom of movement arrangements between States at the regional level (e.g. European Union).
Immigration - A process by which non-nationals move into a country for the purpose of settlement.
Internally Displaced Person (IDP) - Persons or groups of persons who have been forced or obliged to flee or to leave their homes or places of habitual residence, in particular as a result of or in order to avoid the effects of armed conflict, situations of generalized violence, violations of human rights or natural or human-made disasters, and who have not crossed an internationally recognized State border (Guiding Principles on Internal Displacement, UN Doc E/CN.4/1998/53/Add.2.). See also de facto refugees, displaced person, externally displaced persons, uprooted people.
Irregular migration - Movement that takes place outside the regulatory norms of the sending, transit and receiving countries. There is no clear or universally accepted definition of irregular migration. From the perspective of destination countries it is entry, stay or work in a country without the necessary authorization or documents required under immigration regulations. From the perspective of the sending country, the irregularity is for example seen in cases in which a person crosses an international boundary without a valid passport or travel document or does not fulfil the administrative requirements for leaving the country. There is, however, a tendency to restrict the use of the term βillegal migrationβ to cases of smuggling of migrants and trafficking in persons.
Labour migration - Movement of persons from one State to another, or within their own country of residence, for the purpose of employment. Labour migration is addressed by most States in their migration laws. In addition, some States take an active role in regulating outward labour migration and seeking opportunities for their nationals abroad.
Migrant - IOM defines a migrant as any person who is moving or has moved across an international border or within a State away from his/her habitual place of residence, regardless of (1) the personβs legal status; (2) whether the movement is voluntary or involuntary; (3) what the causes for the movement are; or (4) what the length of the stay is. IOM concerns itself with migrants and migrationβrelated issues and, in agreement with relevant States, with migrants who are in need of international migration services.
Migration - The movement of a person or a group of persons, either across an international border, or within a State. It is a population movement, encompassing any kind of movement of people, whatever its length, composition and causes; it includes migration of refugees, displaced persons, economic migrants, and persons moving for other purposes, including family reunification.
Migration management - A term used to encompass numerous governmental functions within a national system for the orderly and humane management for cross-border migration, particularly managing the entry and presence of foreigners within the borders of the State and the protection of refugees and others in need of protection. It refers to a planned approach to the development of policy, legislative and administrative responses to key migration issues.
Naturalization - Granting by a State of its nationality to a non-national through a formal act on the application of the individual concerned. International law does not provide detailed rules for naturalization, but it recognizes the competence of every State to naturalize those who are not its nationals and who apply to become its nationals.
Orderly migration - The movement of a person from his or her usual place of residence to a new place of residence, in keeping with the laws and regulations governing exit of the country of origin and travel, transit and entry into the destination or host country.
Push-pull factors - Migration is often analysed in terms of the βpush-pull modelβ, which looks at the push factors, which drive people to leave their country (such as economic, social, or political problems) and the pull factors attracting them to the country of destination.
Receiving country - Country of destination or a third country. In the case of return or repatriation, also the country of origin. Country that has accepted to receive a certain number of refugees and migrants on a yearly basis by presidential, ministerial or parliamentary decision.
Refugee - A person who, βowing to a well-founded fear of persecution for reasons of race, religion, nationality, membership of a particular social group or political opinions, is outside the country of his nationality and is unable or, owing to such fear, is unwilling to avail himself of the protection of that country. (Art. 1(A)(2), Convention relating to the Status of Refugees, Art. 1A(2), 1951 as modified by the 1967 Protocol). In addition to the refugee definition in the 1951 Refugee Convention, Art. 1(2), 1969 Organization of African Unity (OAU) Convention defines a refugee as any person compelled to leave his or her country "owing to external aggression, occupation, foreign domination or events seriously disturbing public order in either part or the whole of his country or origin or nationality.β Similarly, the 1984 Cartagena Declaration states that refugees also include persons who flee their country βbecause their lives, security or freedom have been threatened by generalised violence, foreign aggression, internal conflicts, massive violations of human rights or other circumstances which have seriously disturbed public order.β
Remittances - Monies earned or acquired by non-nationals that are transferred back to their country of origin.
Repatriation - The personal right of a refugee, prisoner of war or a civil detainee to return to his or her country of nationality under specific conditions laid down in various international instruments (Geneva Conventions, 1949 and Protocols, 1977, the Regulations Respecting the Laws and Customs of War on Land, Annexed to the Fourth Hague Convention, 1907, human rights instruments as well as customary international law). The option of repatriation is bestowed upon the individual personally and not upon the detaining power. In the law of international armed conflict, repatriation also entails the obligation of the detaining power to release eligible persons (soldiers and civilians) and the duty of the country of origin to receive its own nationals at the end of hostilities. Even if treaty law does not contain a general rule on this point, it is today readily accepted that the repatriation of prisoners of war and civil detainees has been consented to implicitly by the interested parties. Repatriation as a term also applies to diplomatic envoys and international officials in time of international crisis as well as expatriates and migrants.
Resettlement - The relocation and integration of people (refugees, internally displaced persons, etc.) into another geographical area and environment, usually in a third country. In the refugee context, the transfer of refugees from the country in which they have sought refuge to another State that has agreed to admit them. The refugees will usually be granted asylum or some other form of long-term resident rights and, in many cases, will have the opportunity to become naturalized.
Stateless person - A person who is not considered as a national by any State under the operation of its lawβ (Art. 1, UN Convention relating to the Status of Stateless Persons, 1954). As such, a stateless person lacks those rights attributable to nationalidiplomatic protection of a State, no inherent right of sojourn in the State of residence and no right of return in case he or she travels.
Xenophobia - At the international level, no universally accepted definition of xenophobia exists, though it can be described as attitudes, prejudices and behaviour that reject, exclude and often vilify persons, based on the perception that they are outsiders or foreigners to the community, society or national identity. There is a close link between racism and xenophobia, two terms that can be hard to differentiate from each other.
