This made them the second-largest Korean population in the region, having surpassed the population in Qatar which shrank during the same period. 43 were Saudi nationals, 65 were international students, and the remaining 2,713 had other kinds of visas. 1,479 lived in Damman, 607 in Riyadh, 394 in Jeddah, 134 in Medina, 100 in Jizan, and 11 in 'Asir Province. There are two Korean international schools in Saudi Arabia: Korean International School of Jeddah (KISJ; ) and Korean School in Riyadh (). The United Arab Emirates received a small contingent of Korean migrant workers in the late 1970s and early 1980s, but it was never a major destination. However, due to rapid growth since 2005, the country has come to have the Arab world's largest Korean population. , there were roughly 2,500 South Koreans living in Dubai alone, largely businessmen working at the 90 Korean companies which operated in the country. Rapid population growth continued through 2011; by that year, South Korean consular statistics showed 5,665 of their nationals or former nationals living in the UAE, giving it the region's largest South Korean population, with more than twice as large a population as that in Saudi Arabia. Five were Emirati nationals, fourteen were international students, and the rest had other types of visas. 3,276 lived in Dubai, 1,982 in Abu Dhabi, 141 in Sharjah, 83 in Ajman, 67 in Ras al-Khaimah, 36 in Fujairah, and 22 in Umm al-Quwain. Many South Koreans in the UAE are flight attendants working for Emirates Airlines; the number of Koreans working for Emirates Airlines increased from 15 in 1998 to 620 as of 2007, mostly based out of Dubai. Dubai has the UAE's largest community of South Koreans. However, a consulate was not opened in Dubai until March 2008. In Abu Dhabi, Reem Investments plans to develop a residential complex for South Korean expatriates on Al Reem Island, and have engaged Gansam Architects of Seoul to design its cultural centre. There are also believed to be roughly 1,300 North Korean workers in the UAE, primarily in Dubai and Abu Dhabi. They earn between US$300 and $500 per month, but have to make so-called "loyalty payments" of $150 to $250 to the North Korean government. This has sparked discontent among the workers; in response, the North Korean government has sent security agents to patrol North Korean work camps and keep an eye out for people making critical comments.
