were recruited personally or answered advertisements and were flown to Korea, often with entertainer or tourist visas. In some instances, once these visa recipients arrived in the country, employers illegally held victims' passports. In addition some foreign women recruited for legal and brokered marriages with Korean men ended up in situations of sexual exploitation, debt bondage, and involuntary servitude once married. Korean women were trafficked primarily for sexual exploitation to the United States, sometimes through Canada and Mexico, as well as to other countries, such as Australia and Japan. Relatively small numbers of migrants seeking opportunities in the country were believed to have become victims of trafficking as well, although the MOL Employment Permit System reduced the number of workers trafficked into the country. There were reports that human traffickers exploited ROK passports for the purpose of human trafficking. There was no credible evidence that officials were involved in trafficking. The law prohibits trafficking for the purpose of commercial sexual exploitation, including debt bondage, and prescribes up to 10 years' imprisonment. Trafficking for forced labor is criminalized and carries penalties of up to five years' imprisonment. February revisions to the Passport Act allow for restricted issuance or confiscation of passports of persons engaging in illegal activity overseas, including sex trafficking. However, some NGOs believed the laws against sex trafficking were not being enforced to their fullest potential. During the year authorities conducted 220 trafficking investigations and prosecuted in 31 cases, all for sex trafficking. There were no reported prosecutions or convictions of labor trafficking offenses. The Marriage Brokerage Management Act, which entered into effect in June, regulates both domestic and international marriage brokers and prescribes penalties for dishonest brokers, including sentences of up to three years' imprisonment or fines. There also are laws to protect "foreign brides" in the country and punish fraudulent marriage brokers, but NGOs claimed the laws needed to be strengthened. The KNPA and the MOJ were principally responsible for enforcing antitrafficking laws. The government worked with the international community on investigations related to trafficking. The government maintained a network of shelters and programs to assist victims of abuse, including trafficking victims. Victims were also eligible for medical, legal, vocational, and social support services. NGOs with funding from the government provided many of these services. NGOs reported that there was only one counseling center and two shelters in the country dedicated to foreign victims of sex trafficking.
