Hi and welcome,

I agree with Muppity. Ring them and get onto Immigration about his residency.

We have been through the Immigration thing and it is really stressful. I am married to an aussie but i am British. When we had DD i was only a temporary resident. DH was still able to get the baby bonus and we were able to get FTB A and B.
I am currently a permanent resident and looking into applying for my citizenship test

GL with everything. If you have any questions feel free to pm me
