You better to send her to the boarding house (but you still have to pay), no eye see and no need to take are of her.....
Which agent you are using? I think they will ask you to give her a body check when they arrive HK, even they checked in their country. I will pay my helper to have the body check once they come back from other country because I also have young kids.
Well, HK govt is so protect to all kinds of workers. They can enjoy more than HK employees benefits, for example, if they die in an accident, not in the working hour or not because you ask her to do something, you still have the liabilty to pay all the fees. The labour dept said because you are overseas worker......I will suggest all the employer not to let them go out that often to minimise the risk!
