With the rising number of foreign visitors to Jejudo Island, the number of illegal residents in the southern resort is also surging, statistics showed Tuesday.
In recent years, nearly 3 million foreigners have visited the island each year, with 85.3 percent of them being Chinese who can enter without a visa, as of 2015.
The number of illegal immigrants in Jejudo has rapidly increased from 282 in 2011 to 371 in 2012, 731 in 2013, 1,450 in 2014 and 4,353 in 2015, according to the Justice Ministry.
With a shortage of workforce to deal exclusively with illegal residents, the rate of apprehending them has remained low at 29 percent.
