The Immigration Services Agency (ISA) announced Tuesday it will strengthen measures aimed at curbing disappearances of foreign nationals working under the government-sponsored Technical Intern Training Program.

The agency will ban companies and organizations that participate in the program from taking in new trainees if they are found to have violated its conditions and their trainees have gone missing, immigration officials said.

The agency will also share information with overseas organizations and brokers to prevent rogue brokers from imposing conditions that violate trainees' rights.
