(Wikipedia) - Iran's sole school for South Korean nationals, the Tehran Korean School (also known as the Korean Embassy School), was established on April, 30 1976; it uses Korean as the primary medium of instruction, with English used for science and computer classes, and Persian offered as a foreign language. As of 2002, it enrolled 29 elementary-school students.
Koreans in Iran have a history dating back to the 1970s, when South Korean labor migrants began flowing into the country. However, most returned home or moved on to other countries; as of 2011, only 405 Koreans lived in the country, according to the statistics of South Korea's Ministry of Foreign Affairs and Trade.
South Korean migration to Iran grew at an average annual rate of 90% between 1971 and 1977, although the total number of migrants from Korea grew only by an annual average of 18% during that same period; South Koreans departing their home country for Iran composed just 0.2% of all officially-registered emigrants in 1971 (roughly 150 individuals), and only 177 individuals in 1974, but 1.8% (2,402 individuals) in 1975 and 3.4% (6,264 individuals) in 1977. The vast majority were male. Hyundai Construction's first project in the entire Middle East was a 1975 contract for the construction of a shipyard for the Iranian Navy near Bandar Abbas, and they quickly expanded their business in the region. Between 1977 and 1979, nearly 300,000 South Korean workers from two dozen companies came to work in the Middle East. The largest proportion of those went to Saudi Arabia, though Iran was also a major destination; at one point, migration to Iran made up 17% of all migration to the region. In total, in the decade following 1975, 25,388 South Koreans went to Iran.
By 2009, only 614 South Korean nationals remained in the country. They consist primarily of government officials, corporate expatriates, and Koreans married to Iranians. By 2011, the number of South Korean nationals or former nationals in the country had shrunk further, to 405 persons. Among them, 42 (3 men, 39 women) had Iranian nationality, 20 were international students, and the remaining 342 had other kinds of visas. Most (315) lived in Tehran, with a smaller concentration of 32 at Asaluyeh.
