My friend is illegally present. But six months ago, he or she got hurt while working. He/she had to report it as an industrial accident, but he/she did not report it because he/she was staying illegally, and he/she made an agreement with the employer to just receive medical expenses, etc. However, after a few days, the employer is still not paying medical expenses. Now my friend is going to report it to an agency like the Labor Office. But when my friend talked to the employer, he or she threatened not to say it because there will be disadvantages such as forced deportation. Is there really such a risk?
