Back in May, the government launched an incentive program aimed at encouraging foreign workers who overstayed their visa to leave the country “voluntarily”:
Under the program, those who exit will be exempt from fines and will not be regulated on a possible revisit to the country. The authorities are aiming to reduce the number of illegal sojourners here ― estimated at 180,000 ― before the G-20 Summit slated for November. The program will run from May 6 to September 31.
Employers who come clean with such workers will also be granted exemptions from fines and be given priority in recruiting substitute workers.
There was an amusing comment left by ‘ninjalo’ below the article:
Wow, they consider this to be so important that they even added an extra day to September! Way to maintain your constant level of quality, Korea Times!
I digress. Last week it was announced
South Korea will extend a temporary grace period during which foreigners staying in the country illegally can leave and return with a visa without getting punished, the Justice Ministry said Tuesday. The grace period, which began on May 6, was to expire Tuesday, but the ministry has decided to extend it to the end of October to handle a growing number of illegal aliens who were leaving to be exempted from fines and a ban on future reentry.
A total of 8,958 illegal immigrants have left the country as of Aug. 25, showing a 12 percent increase compared to the same period last year, according to the ministry. As the deadline neared, an average of 113 people left the country daily in August, it said.[...]
By nationality, 3,169 ethnic Koreans from China, 780 Mongolians and 682 Thais went back to their home countries, the ministry said. About 180,000 were estimated to be residing in South Korea illegally before the grace period began in May.
