dila ... i just check your nationality is sri lankan, you can't sponsor your family till you receive your resident permit. Your family might only be able arrive on 2 weeks visa. I am not too sure too about this ... last time my mum visiting me ... she only get 2 weeks visa that renewable once inside the country, when you want to renew it again you have to fly out and fly back in again.

my suggestion ... you should wait you got your visa sorted then bring your family in.
