Afghans in Pakistan (, , ) are temporary residents from Afghanistan who are registered in Pakistan as refugees and asylum seekers. They fall under the jurisdiction of the United Nations High Commissioner for Refugees (UNHCR). Most of them were born and raised in Pakistan during the last four decades. Additionally, there are also Special Immigrant Visa applicants awaiting to immmigrate to the United States.
