The Russian Federation's Law on Refugees defines who is a refugee for purposes of obtaining asylum in the country.
 The Law defines a refugee as a "person who is outside his/her country of nationality or habitual residence; has a well-founded fear of persecution because of his/her race, religion, nationality, membership in a particular social group or political opinion; and is unable or unwilling to avail himself/herself of the protection of that country, or to return there, for fear of persecution.
 Upon receiving an asylum seeker's application, the Russian Federal Migration Service ("FMS") determines whether the asylum seeker meets the legislative definition of a "refugee" and should be granted asylum.
Well-Founded Fear is a 2000 documentary film from directors Shari Robertson and Michael Camerini.
 The film takes its title from the formal definition of a refugee under the UN Convention Relating to the Status of Refugees, as a person who deserves protection, "owing to a "well-founded fear" of persecution for reasons of race, religion, nationality, membership of a particular social group, or political opinion.”
 The film analyzes the US asylum process by following several asylum applicants and asylum officers through actual INS interviews.
An asylum seeker (also rarely called an asylee) is a person who flees his or her home country, 'spontaneously' enters another country and applies for asylum, i.e. the right to international protection, in this other country.
 An asylum seeker may be a refugee, a displaced person or a migrant, such as an economic migrant.
 A person becomes an asylum seeker by making a formal application for the right to remain in another country and keeps that status until the application has been concluded.
 The relevant immigration authorities of the country of asylum determine whether the asylum seeker will be granted protection and becomes an officially recognised refugee or whether asylum is refused and the person becomes an illegal immigrant who has to leave the country again and may even be deported.
 The asylum seeker may be recognised as a refugee and given refugee status if the person's circumstances fall into the definition of "refugee" according to the
A refugee, generally speaking, is a displaced person who has been forced to cross national boundaries and who cannot return home safely (for more detail see legal definition).
