u mean u applied on 12 oct and got AOR on 21 oct ? are u applying under AEO or Some 38 list NOC
That is normal in New Delhi office he is not the first one who got his AOR after 10 days from sending the supporting documents to New Delhi, i see in this forum that most people who sent to that office got the AOR within 10 dyas, unlike Buffalo office which took me 28 days to get the AOR by email (so there was no reasons Justified by mailing delays in the process to get it after 28 days !)
