I have a pre arrival registration slip for Indian citizens to enter hong Kong. I wish to enter China via Hong Kong. But the slip says
The issue of the notification slip is not a guarantee of the registrant’s entry to the HKSAR. The registrant is still subject to immigration control under the provisions of the Immigration Ordinance, Chapter 115, Laws of Hong Kong. In general, a person who intends to enter the HKSAR for visit must fulfil normal immigration requirements (such as holding a valid travel document with adequate returnability to his/her country of residence or citizenship; raise no security or criminal concerns to the HKSAR; have no likelihood of becoming a burden on the HKSAR, etc.), have a bona fide purpose of visit, have adequate funds to cover the duration of his/her stay without working and hold onward or return tickets (unless in transit to the Mainland of China or the Macao Special Administrative Region), before entry to the HKSAR may be granted."
Can anyone explain "unless in transit to the Mainland of China or the Macao Special Administrative Region" this part?
