Type of migration

Who are refugees and asylum seekers?

An asylum seeker is “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.”

A refugee is “a person who, owing 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. 1 A(2), 1951 as modified by the 1967 Protocol).”
