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.
