The Rights of Non-citizens

International human rights law is founded on the premise that all persons, by virtue of their essential humanity, should enjoy all human rights. Exceptional distinctions, for example between citizens and non-citizens, can be made only if they serve a legitimate State objective and are proportional to the achievement of the objective. Non-citizens can include: migrants, refugees and asylum seekers, victims of trafficking, foreign students, temporary visitors and stateless people. This publication looks at the diverse sources of international law and emerging international standards protecting the rights of non-citizens, including international conventions and reports by UN and treaty bodies
