Economic migrants

workerThese are people who normally leave their homes and countries voluntarily to seek a better life elsewhere.

They are therefore different from refugees who flee their homes and countries because of the threat of persecution. Economic migrants can normally return home when they choose to, will not face the threat of persecution and will continue to receive the protection of their government.
 
Refugees on the other hand are not able to return safely to their homes unless or until the situation forcing them to leave has been resolved. However, according to a number of reports, some of these people may in fact be environmental refugees, but because there is no international recognition of environmental refugees they end up being classified as economic migrants.
 
The United Nations has a special Agency responsible for assisting refugees?

The United Nations High Commissioner for Refugees (UNHCR) is the UN refugee organization with special responsibility for leading and coordinating international action to protect refugees and solve refugee problems.

It’s most important purpose is to safeguard the rights and well-being of refugees and to ensure that everyone can exercise the right to seek asylum and find a place of safety in another State. Visit the
UNHCR website for further details.
