Help please

Hi,

My company has a position open in HK, which I most likely can get if I apply. I speak Cantonese but my hu*****and doesn't. We are living in New York city, both having a pretty good job. If I apply for this position, my hu*****and will have to find a job in Hong Kong. We don't have children yet.

I appreciate if you can provide any input on these questions:
a. My job will be in Central Hong Kong. To find a flat around 800 sqft use-able living space and within 30 minutes to the office, how much the rent will be?
b. In there a website or somewhere American can look for jobs in/around Hong Kong?
c. is it fair for me if my company keep paying me the same salary? Not sure if there will be re-location package.
d. If we have Children in Hong Kong, will they have due citizenship?
e. how much it will cost of hire a full time house keeper?
f. I know the air in Hong Kong is not perfect because of the factories around. But anything else to be concerned about?

Thanks.
