Hi everyone

My spouse and I want to emigrate to Australia, please, tell us which is the shortest and cheapest way to achieve a VISA for permanent residence in Australia.
Any experience available? any help available.
I am a Chemical Engineer and my wife is a Physical Education teacher with a master degree, we are friendly and want to make friends.
Who has better "elegibility"?
We are starting the process in the Argentinean Embassy.
Best regards

Federico y Carolina
