I have changed my job before 5 months; i also have sent the supporting documents to New Delhi, CIC but not received any acknowledgement for the receipt of my docs. 
I want to know that they have updated my file or not as they have very much back log of files.
Should I send my documents again through mail or ot please guide me.
