A remittance is a non-commercial transfer of money by a foreign worker, a member of a diaspora community, or a citizen with familial ties abroad, for household income in their home country or homeland. Money sent home by migrants competes with international aid as one of the largest financial inflows to developing countries. Workers' remittances are a significant part of international capital flows, especially with regard to labor-exporting countries.

A migrant worker is a person who migrates within a home country or outside it to pursue work. Migrant workers usually do not have an intention to stay permanently in the country or region in which they work.
