Each year, resettlement countries decide how they will allocate resettlement places among the millions of refugees throughout the world. Resettlement countries set the criteria which determine which, and how many, refugees will be admitted to their country. Places are limited and resettlement countries decide how many refugees they will resettle, not UNHCR.
Since resettlement places are very limited, UNHCR must prioritize the cases of refugees who have the most urgent protection needs and vulnerabilities.
