Visiting from the UK - Airport of Arrival with internal Flight - Visiting Hong Kong & Macao
Hello,
I am planning my trip to China from the UK and have several questions when it comes to filling my VISA request.
1) Regarding the Travel information. From London, I will be entering China from Beijing and from the same airport I am then taking a flight to Shenzhen. In my visa application, should I put arrival Beijing or Shenzhen?
2) When in Shenzhen, I will be visiting Hong Kong for 3 days and have a day trip to Macao. I guess that for this I will need a "double entry" visa as I'll be going back to Shenzhen, right?
3) I am planning to travel to Shenzhen to Hong Kong and back via train, this shouldn't be an issue, right?
4) When I want to add "Hong Kong" to my itinerary on the "destinations" I only have the option of "Hong Kong Island" I guess that is the option I need to put down and that the day trip to Macao doesn't need to be added on the destinations.
5) Trying to find the answers to my questions on google I came across this which confused my quite a lot:
---- Can I use Chinese visa to enter Hong Kong? The "CHINESE VISA" without word "HONG KONG" or " MACAO" is only valid for mainland of China. The "CHINESE VISA" with word "HONG KONG" is only valid for HONG KONG SAR of China. The "CHINESE VISA" with word "MACAO" is only valid for MACAO SAR of China.
Would I need to have any other type of visa to visit Hong Kong and Macao?
I am preparing the visa from the UK as I want to avoid having to deal with this while in China or Hong Kong.
