No contact from CO or visa grant after 189 visa lodgement

Dear, Its been 37 days since i have lodge visa however, till now i didnt recieve any updates from DIBP Can any one let me know that this is normal behavior or is somehting, My status is still received. Also is there any standard does DIBP or CO follows to respond for example 28 days.
Hi Shaikh , Same case with me . any updates ?
What ANZSCO did you apply in? What documents did you submit?
Mine took about 25 days to get back. Are you accounting for any extended holidays ?
Who is your case officer?
today is 406th day still waiting my 190 visa grant.....
There is no specific time frame. Processing on your case must have started. Either you might get a direct grant if they are comfortable with your application or will ask you for additional documents. So relax and wait
same case with me..489..6 month still assessment in progress that's it
