While emigration was restricted under Nasser, thousands of Egyptian professionals were dispatched abroad in the context of the Arab Cold War. Egyptian emigration was liberalised in 1971, under President Sadat, reaching record numbers after the 1973 oil crisis. An estimated 2.7 million Egyptians live abroad. Approximately 70% of Egyptian migrants live in Arab countries (923,600 in Saudi Arabia, 332,600 in Libya, 226,850 in Jordan, 190,550 in Kuwait with the rest elsewhere in the region) and the remaining 30% reside mostly in Europe and North America (318,000 in the United States, 110,000 in Canada and 90,000 in Italy). The process of emigrating to non-Arab states has been ongoing since the 1950s.
