Time to tighten oversight over expat job visas

Editor's note: Some parents complain on the social media that many foreign English language teachers employed by private training agencies are not qualified or inexperienced to teach, and their children see little progress in their English language abilities after learning from the teachers for months or even years. China Daily writer Li Yang comments:

The problem is not limited to the circle of English teachers, but also some sports coaches in the youth training market. It is an open secret that some expats are making good money in jobs they are not qualified for.

Some build up their learning curve quickly and gain experience in teaching and tutoring, but more commonly they job-hop from one employer to another in different cities. The youth training market in China is so large that the demand for foreign teachers far exceeds supply. So it is not difficult for them to earn their living this way.
