Since I visit HK often as tourist, can I obtain an HKID as a visitor? This ID offers ease of passage to HK among other benefits. Do you know the specifics? The HKID also lets you open bank accounts to park some funds for spending in HK.
No, but if you're really desperate, enrol in the cheapest uni course you can find and get a student visa for that, which will then let you get a HKID.
