Tourist Visa for H/K.

You can visit HK from Singapore, but you need to have a HK Tourist/Transit permit to visit that city in advance since you have Sri Lanka passport. All Sri Lanka passport holders need to apply it.

You are suggested to apply it by mailing your documents to HK Immigration Department for application. For applying it, you need to prepare your valid passport, an application form, a recent taken photo, your hotel bookings, your round trip tickets, your travel plan and your bank statement for application.
