As long as you have met the min required points at 67 or more plus u can provide all the necessary documents, I have NOT heard of single case where it has been declined.  

There could be cases where criminal records could have an effect on your chances.  But if you are clean, why bother to spend on thousands for the agent fee?

Listen, it doesnt take a rocket scientist to fill up the forms and submit the necessary documents to the authority.

Please proof to em otherwise. Thanks
