They are considered a huge burden on the economy, environment and infrastructure of the country. At the time of NATO withdrawal from Afghanistan, Several countries and international organizations were involved in efforts to evacuate Afghan refugees and provide them with safe haven. Pakistan has also provided them shelter. Now the government of Pakistan warned and ordered forced repatriation to Afghanistan by October 2023. It planned for 1.73 million illegal Afghan people who are living without any documents. The study finds the problem of Afghan refugees in Pakistan is a social, economic and political threat to the country.
