A refugee, generally speaking, is a displaced person who has been forced to cross national boundaries and who cannot return home safely. Such a person may be called an asylum seeker until granted refugee status by the contracting state or the United Nations High Commissioner for Refugees (UNHCR) if they formally make a claim for asylum. The lead international agency coordinating refugee protection is the United Nations Office of the UNHCR. The United Nations has a second office for refugees, the United Nations Relief and Works Agency (UNRWA), which is solely responsible for supporting the large majority of Palestinian refugees.
