If your friend is working on a Z visa, then you can go to the PSB or foreign experts office to resolve the dispute. However, if she is working on a L or F visa, there will be no solution with the authorities, as it is illegal to work while holding such visas.

If it is an L or F, and this is a training center, which I think is what we all expect it to be, then I guess what I would do is run away to another town, and threaten not to teach until your documents are returned to you.

Also, she could consider reporting that her passport was stolen by that school owner after he promised her a few weeks volunteering at the school. However, this is risky.

Poster, please post more information about the case.

\\Thanks.
