If you want to apply again, then you need to carefully consider:
1. You have only Filed your tax, and you have not paid any $ to the HK government yet.
So you may need to wait until you have actually paid up your Salaries tax and Provisional Tax in full and have the Tax RECEIPT. Sadly only Tax filing is not sufficient as the HK government cannot verify that you have PAID your tax.
The requirements from the Immigration website are quite clear :
Photocopy of proof of the sponsor's financial standing, e.g. bank statements, savings accounts passbooks, tax receipts and salary slips
2. The officer is correct ... the guidelines only allow for dependant PARENT for : ...
a sponsor who is a Hong Kong permanent resident or a resident who is not subject to a limit of stay (i.e. a resident with the right to land or on unconditional stay)
Sadly , you are not. Your stay does have a limit.
Others who are similar to your situation that got a dependent without PR.... is because they have less number of dependents.
You already have 2 dependents.... if include this application, then you would end up with 3 dependents; the question comes : can you afford ?
Assume your salary at 70k per month... it now supports 3 people (yourself + 2 dependent) so "expenses" are approximately 70k/3 = 23k each person
If you have one more .... it needs to support 4 people so 70k/4 = 17k each person .... which is less than 20k. It is quite low for hong kong; and the financial capability would be questioned by Immigration.
To be able to "sponsor" 3 dependents plus yourself.... looking at around 23k x 4 = 92k and your salary needs to be almost 100k per month.
Thanks everybody for replying! The immigration officer refused the visa, but allowed me to withdraw the application so that an official visa rejection doesn't come on record.
The prolonged visitor visa will allow her to remain in HK and you can renew it every 6 months without her having to leave. However, no ID card so no health cover.
