All migrants, regardless of their migration status, are entitled to the full respect, protection and fulfilment of their human rights. The UN Secretary-General has noted that, notwithstanding the gradual expansion of refugee protection, many people are compelled to leave their homes for reasons that do not fall within the 1951 definition of a refugee. Where migrants in situations of vulnerability fall outside the specific legal category of “refugee”, care must be taken to ensure that their human rights are nevertheless respected, protected and fulfilled. In collaboration with DLA Piper Law Firm, the Center for Legal and Social Studies (CELS) and the Center for Human Rights and Citizenship of the Immigrant (CDHIC), OHCHR has undertaken a mapping project to better understand existing mechanisms for admission and stay based on human rights or humanitarian protection grounds.
