Once a visa is granted to a dependant who is still overseas, how long does that person have to enter HK? Can the person enter anytime within the visa's period (i.e. 1 or 2 years), or does the person have to enter within a specific shorter period (e.g. 30/60 days)?
Let's say the visa is granted on 1 March 2025 for 2 years to a 65-year-old parent of an HKPR.
