What is a third country visa? Does the Hong Kong and Macao Pass count as a third country visa?

Accurately speaking, it should be called "third place visa", which is a rule that is often seen in immigration and transit in Hong Kong and Macao.

1) When passing through Hong Kong and Macao with a passport of the People's Republic of China, you need a third place (country) visa to enter the country;

2) Hong Kong investment immigrants do not accept the status of China people and Chinese mainland residents, and must have permanent residence status (visa) in a third country;

This concept is sometimes used when you need to transfer through other countries. For example, if you go to Australia via Singapore, then an Australian visa is a "third country".

Hong Kong and Macao Pass does not count as a third country visa.
