hats why she was refused again, because her visa in entering Hongkong is a tourist visa and you are not allowed to worked, then exited to China and after few days went back to Hongkong.Naturally the immigration officer detect that there's something wrong with it.Thats violation of the immigration law I think.Working visa in Hongkong is good for two years but they changed the laws when Hongkong was turned over to the Chinese government, so its the same two years but you have to exit after one year for few days to restamped your passport and to avoid people applying for residency.Before when Hongkong was under British rule many domestic worker can apply residency after working for two years or more thats why the changed it to avoid over crowding.
