The government Wednesday decided to allow ethnic Koreans abroad to hold jobs in Korea in restaurants, social welfare facilities, cleaning and other service sectors, for a couple of years beginning Nov. 1st. Under the new measure to reduce illegal aliens in the service industry and solve a manpower shortage in the construction industry and small businesses, the government will raise the number of industrial trainees by 18,750 to 145,500 so the labor shortage can be resolved in the fishing and construction industries and small- and medium-sized firms. Those with F1 visas, which are issued to ethnic Koreans who have relatives in Korea, are eligible for up to two years' employment in this country's service industry. Entertainment businesses will not be permitted to employ ethnic Koreans from abroad. The government will lower the minimum age for F1 visas to 40 from 45 beginning Nov. 1st. Owners of restaurants, cleaning agencies and other service firms can hire a maximum of 10 F1 visa holders if they prove that they had failed to fill the post with Korean nationals for one month or more. Government figures show that 337,000 foreign workers stay in the country, as of the end of March, and 266,000 of these had overstayed their visas.
