Thank you Cippalippa. We upload all necessary documents on 15 June with medicals. I knew that Belgrade council have questioned my colleague for me and my family 2 weeks after that. And our status is still "Application received" without any request. I wrote to the Department, and they said me that my case is process of assessment. Now my employer will wrote to them to complain for processing time, I hope this to move our case.
My case is the same like your - I lodged the 457 application myself (the employee part) while the MA lodged the nomination only on behalf of my employer.
