Hi i want me and my family to visit in hongkong do my family need a visa?

If your family hold philippine passport and just stay in HK for less than 14 days, it is not needed. But they need to show their round trip tickets and hotel booking confirmation letter together with passport when they enter HK.
If they want to stay longer, they need to apply in advance.

If they have UK's passport, they can enjoy a 180 exemption stay in HK.
