Firstly, you should prepare the required materials including copy of your passport, the filled-out application form affixed with a passport-style photo, proof of your financial support, transportation arrangement, hotel booking record and your travel itinerary to HK.
Afterwards, post your application to HK immigration department to apply for it if it’s the first time you apply for it. Here is the postal address: Receipt and Dispatch Sub-unit
HK Immigration Department
2/F, Immigration Tower
7 Gloucester Road
Wan Chai, HK

thank you
