With Indian passport, you are not required visa to HK for 14 days, so, here you are suggested to apply for a visa when you are in HK. Documents needed are your passport, application form for HK visa, photo. Sometimes, you may be required to provide return ticket, hotel reservation or financial proof for travel if visa officers deem them necessary. Visa fee is HK$160 paid in cash.
