How to get Hong Kong transit visa from Sri Lanka?

Hey, Sandhya, the first thing you need to do is to prepare the required materials including your passport and its photocopy, your recently-taken bareheaded photo and the application form, proof of transportation arrangement, and proof of the proposed visit in the next destination after transiting in HK or itinerary as well as financial proof.
