Ten foreigners have been deported for working without work permits at a golf resort in Jeju City, law enforcement officials said Sunday.
The golf course operator was apprehended and fined for employing the undocumented workers.
Police and immigration officials raided Jeju golf resorts on March 12.
Last year Jeju prosecutors charged three managers of a renowned Jeju golf resort for employing up to 360 undocumented Chinese workers.
Construction, manufacturing, and agriculture sectors rely heavily on undocumented foreign labor.
The number of undocumented immigrants in Korea totalled 208,971 in 2016, according to the Ministry of Justice. There were 2,049,441 foreign residents, a 9 percent increase on five years ago.
