An asylum seeker is a person who has left their country and is seeking protection from persecution and serious human rights violations in another country, but who hasn't yet been legally recognised as a refugee and is waiting to receive a decision on their asylum claim. Persecution might be the result of people’s race and ethnicity, religion, nationality, political views, as well as a range of other social and cultural issues.
A refugee is a person who has been officially granted this protection, legally recognised as needing safety from persecution, violence, or war, and is unable to return to their home country. In the UK, people may be granted refugee status through their claim for asylum in the UK or through one of the UK government’s refugee resettlement schemes.
An economic migrant is a person who has left their country to move to another country primarily for employment and/or to find better economic opportunities.
