Afghan diaspora
Afghan diaspora or Afghan immigrants are citizens of Afghanistan who have immigrated to other countries, or people of Afghan origin who are born outside Afghanistan. Traditionally, the borders between Afghanistan and its southern and eastern neighbouring countries have been fluid and vague. Like other nations that were created by European empires, the borders of Afghanistan with neighboring countries often do not follow ethnic divisions, and several native ethnic groups are found on both sides of Afghanistan's border. This means that historically there was much movement across present day barriers.
Since the Soviet invasion of Afghanistan in 1979, a total of about 6 million Afghan refugees have settled in neighboring Pakistan and Iran. However, between 2002 and 2015, more than half of that population have been repatriated to Afghanistan with UNHCR's assistance. In the same period, several NATO countries that were part of ISAF granted political asylum to smaller number of Afghans that worked with their respective forces. As opposed to fleeing to neighboring Pakistan or Iran, Afghan Sikhs and Afghan Hindus, often journeyed to India. Those who were granted asylum or immigrant visas eventually made it to Western countries, where many other Afghans had gone for permanent settlement. Afghan natives now reside in at least 78 countries around the world.
