– December 1971) of the migration was from areas in the present-day Indian states of U.P., Delhi, Gujarat, Rajasthan, Maharashtra, Madhya Pradesh, Karnataka, Telangana, Andhra Pradesh, Tamil Nadu, and Kerala. The main destination of these migrants was Karachi and the other urban centers of Sindh. In 1952, a joint passport system was introduced for travel purposes between the two countries which made it possible for Indian Muslims to legally move to Pakistan. Pakistan still required educated and skilled workers to absorb into its economy at the time, due to relatively low levels of education (15.9 percent in 1961) in Pakistan. As late as December 1971, the Pakistan High Commission in New Delhi was authorized to issue documents to educationally-qualified Indians to migrate to Pakistan. The legal route was taken by unemployed but educated Indian Muslims seeking better fortunes, however poorer Muslims from India continued to go illegally via the Rajasthan-Sindh border until the 1965 India-Pakistan war when that route was shut. After the conclusion of the 1965 war, most Muslims who wanted to go to Pakistan had to go there via the East Pakistani-India border. Once reaching Dhaka, most made their way to the final destination-Karachi. However, not all managed to reach West Pakistan from East Pakistan. In 1959, the International Labour Organization (ILO) published a report stating that between the period of 1951–1956, around 650,000 Muslims from India relocated to West Pakistan. However, Visaria (1969) raised doubts about the authenticity of the claims about Indian Muslim migration to Pakistan, since the 1961 Census of Pakistan did not corroborate these figures. However, the 1961 Census of Pakistan did incorporate a statement suggesting that there had been a migration of 800,000 people from India to Pakistan throughout the previous decade. Of those who had left for Pakistan, most never came back. The Indian Prime Minister Jawaharlal Nehru conveyed distress about the continued migration of Indian Muslims to West Pakistan:There has...since 1950 been a movement of some Muslims from India to Western Pakistan through Jodhpur-Sindh via Khokhropar. Normally, traffic between India and West Pakistan was controlled by the permit system. But these Muslims going via Khokhropar went without permits to West Pakistan. From January 1952 to the end of September, 53,209 Muslim emigrants went via Khokhropar....Most of these probably came from the U.P. In October 1952, up to the 14th, 6,808 went by this route. After that Pakistan became much stricter on
