Also HSBC has branches in the US, I'm planning on openning an account in the next few days so even if I have to open another one when I get to HK at least all I have to do on payday is transfer funds from one account to the other, and no wire transfer between two diff. banks.
I already asked them if I still need to open an account on indoc. day if I already have an HSBC account and they responded with this "you can just open one when you get here on indoc day", so we'll see.
