Didn't you apply for the Health and Quarantine Certificate for International Travellers in China?
As long as you have this health certificate, no matter what it says, as long as you get it, you can claim compensation from the health inspection center. If you don't do it, the responsibility is your own. Of course, your personal responsibility also includes the responsibility caused by the misleading of the labor service company.
However, even if the medical examination fails, you can usually get the deposit back. Whether you are in breach of contract depends on your contract. The state expressly stipulates that no deposit is allowed. You'd better forget the cost of going abroad. Labor service companies are not easy. You spent all your commission on the plane ticket, so people can't lose money.
But the deposit must be refunded to you.
Give me some points!
