Advanced Processing

Can anyone please tell me what "advanced processing" means?

I keep receiving this reply from them:
Your application is at an advanced stage of processing & you will be
informed of the Ministers decision as expeditiously as possible.

What is basically means is that your application has gone through the screening and checks stage etc and now will be forwarded to the minister for approval. This could happen any time soon. I am not sure if they are still sending some approvals as some people got approvals around 15th/16th July and some around 24th July. So you may also get in the next batch good luck mate !

After having finished all the checks and screening.. you said approval? is there any chance the minister could refuse after all that?
many thanks for the info man

Its hard to determine really however would you like to share the date of your application and 2nd letter acknowledgment letter etc? The reason I am asking is that if it didn't take long for your application to reach advance stage then chances are there wont be any issues and therefore it will be approved, usually applications that involve complexities take longer than average to process.
