I normally put my Receipt number (which you got from your payment receipt) to login. However, if you cannot login, it may mean they have not started to process your application.
When exactly did you send the application ah? Just checked the processing times on their website, they are processing applications received on Feb1, 2012. So if they are not processing your file yet, then you cannot login.
Yes, I have check that , may be now are many many people to apply, and I saw that they only update every Tueday 真係慢到 The Client Application Status site is updated weekly, usually on Tuesdays.
I also want to know :
1. I need to click "Hong Kong SAR" or "Hong Kong"
2. and the name is click my name or my husband name ?
I think I chose "Hong Kong". I used my (sponsor's) name. But I'm not sure if everyone is the same so I would just try with both you or your husband's name so you won't miss it.
