Governments normally guarantee the basic human rights and physical security of their citizens. But when civilians become refugees this safety net disappears. UNHCR's main role in pursuing international protection is to ensure that states are aware of, and act on, their obligations to protect refugees and persons seeking asylum.
A stateless person is someone who is not recognized by any country as a citizen. Several million people globally are effectively trapped in this legal limbo, enjoying only minimal access to national or international legal protection or to such basic rights as health and education.
Using the 1951 Geneva Refugee Convention as its major tool, UNHCR's core mandate is to ensure the international protection of uprooted people worldwide. It promotes the basic human rights of refugees and that they will not be returned involuntarily to a country where they face persecution.
