Sounds like I won't be going with standard chartered then. I was thinking Citi but when I checked their Citi Plus page you need to have a permanent HKID so maybe HSBC and then an Amex?
Just FYI, with citi you can link international accounts. The staff are friendly and helpful to get you set up here. SC also has good customer service. I think your citi idea is good, although I don't specifically know about cc.
