Since 2021 the Bolivia–Chile border has been a major point of entry of irregular Venezuelan migrants into Chile.^[5] Migrants are aided in the crossing by human smugglers.^[6] Irregular migration has been particularly troublesome for the Chilean border town of Colchane.^[6][7]

Indigenous Aymara communities live on both sides of the border.^[8]
