Yes, but it needs to be determined based on the place where your certificate is issued (where your household registration is located).

1. If the place of issuance (the place of household registration) is one of the cities open to free travel in Hong Kong, you can change the group visa to an individual visa.

2. If the place of issuance (the place of household registration) is not a city that is open to free travel in Hong Kong, you can only apply for a group visa and cannot change it to an individual visa.

3. The only difference between group travel and individual travel is that individuals can pass through customs freely, while groups need to be listed on the travel agency’s group list before entering customs. This is only a difference in customs clearance and does not affect anything else.
