Do I need to submit documents for ECNR during the renewal of validity?
If it is changing from ECR to ECNR then yes. Or else NO. If it is an existing NON ECR passport you need only the first 2 and last 2 pages of the passport and AADHAR. IF THERE IS NO CHANGE IN THE PASSPORT, AND IF THE VALIDITY IS DUE TO EXPIRE AND NOT EXPIRED ALREADY YOU WILL RECEIVE YOUR PASSPORT IN 7 DAYS. I HAD MY PASSPORT SUCCESSFULY REISSUED WITHIN 5 DAYS WITHOUT POLICE VERIFICATION AS THERE WAS NO CHANGE AND IT WAS WITHIN VALIDITY.
