I am US citizen and also have Hong Kong Permanent Resident Card (with Chinese SAR passport). I am currently living and working in US. I have never lived nor worked in HK. Now I am thinking applying a job in HK and if it it goes through, should I use US citizen to apply for a working visa as expat or using HK ID to work? As for tax filing, should I file as an expat? I know I need to file tax with US IRS anyway.
Thanks in advance.
