Let me get home

Me and my wife have been married for 3 years, she being in the USA and I in Australia.  I have 2 wonderfull sons (well step sons but to me they are my sons) with her, and I want to be able to be with them every day.  At the moment I only get to be with them for 6 weeks a year over the christmas break.  I am going though the visa process to be able to be with them  but with some of the expenses that come with it I would like to ask for help.    
My wife and sons mean the world to me and I want to be there with them.
