We are in the same situation. My sister's work permit was refused due to that reason. They told her that she can re-apply as long as there is a new significant reason that she will go back after her contract. She has to start from the beginning again ,wait another 4 months. She also sent proof of funds with her application but the visa officer did not acknowledge the funds or was not convince with the amount of money she has put in the fund. Her employer been waiting for over 4 months now and I have to break the news to her employer. I am thinking of sponsoring her as my live in caregiver as I need one.
Why would you send "proof of funds" to the visa officer? Proof of funds is only applicable to foreign skilled worker applicants who doesn't have a job offer or employer.
