Apparently the South Korean authorities decided to suspend work visas for Vietnamese workers due to rampant illegal immigration:
No more Vietnamese workers would be sent to South Korea this year, according to the Vietnam’s Overseas Worker Centre under the Ministry of Labour, Invalids and Social Affairs.
Phan Van Minh, director of the centre, said that South Korea has stopped recruiting new Vietnamese workers.
“From now until the end of this year, only loyal workers who have worked for at least four years and ten months at a South Korean enterprise without quitting or switching jobs, and those who have finished their labour contracts and returned to Vietnam, will be eligible to return to the country,” Minh said.
Since last December, the centre has received more than 13,900 applications from Vietnamese workers, and about 2,800 have been selected by South Korean employers.
The rest must wait until next year, he said, adding that South Korea had announced that Vietnam would be one of 15 countries with a recruitment quota of 62,000 next year.
More than 560 workers meet the criteria to return to South Korea, of which 430 have registered to go and 210 have been granted visas.
Minh said that the regulation took effect this July and aimed to tackle the inflow of illegal immigrant workers to the country.
Figures from the ministry last month showed that about 75,000 Vietnamese workers were working in South Korea, 15,000 of whom illegally cancelled their labour contracts to work for other employers. [AsiaOne]
