Assimilation - Adaptation of one ethnic or social group – usually a minority – 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.
Assisted Voluntary Return - Administrative, logistical, financial and reintegration support to rejected asylum seekers, victims of trafficking in human beings, stranded migrants, qualified nationals and other migrants unable or unwilling to remain in the host country who volunteer to return to their countries of origin.
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 "reverse brain drain".
Capacity building - Building capacity of governments and civil society by increasing their knowledge and enhancing their skills. Capacity building can take the form of substantive direct project design and implementation with a partner government, training opportunities, or in other circumstances facilitation of a bilateral or multilateral agenda for dialogue development put in place by concerned authorities. In all cases, capacity building aims to build towards generally acceptable benchmarks of management practices.
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: “Everyone has the right to freedom of movement and residence within the borders of each state.”), 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: "Everyone 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.
