Hi! Thanks for your reply!
Basically I have already submitted most of the required documents in immi’s record because I needed them to lodge the 476 a few months ago.
I applied 187 by an agent.
The documents were passport, birth certificate, IELTS (at least 6 in each band), my CV, massage diploma, marriage certificate, police check in Australia.
I gave my 80 (used to apply 476) to my 187 agent. I was not sure if he filled in some forms for us. (?) I have just asked him.
