HI LILY
do not worry about it- 475 is the pathway to 887, and it is the condition visa. DIAC could not do it. The main reason is 887 is onshore application. do you know what does that mean? It means you can stay here as long as you can
I could not type chinese since I am in the office
yanq111, please have a look at my previous response - ask your friend send the feedback to DIAC. if you are just waiting - do not expect some miracle, and DIAC will assess your case by order.
The answer from DIAC operator is totally understandable, and what will your friend to expect hear from them? The main reason you called them to get the info of CO, and hang up to make another call to get it if you think you really want the info as you find the operators are not helpful.
On the other hand, try to visit DIAC office in person like I mentioned before.
