H1B drop box Administrative processing time

Hi…

what is the processing period for H1B visa stamping through drop box? I submitted my document on 01May2017 at chennai. The status changed to " Administrative processing" on 03May2017. There is no change in status till now.

Not sure how much the processing time is. I submitted docs in mumbai on 1st may and since 2nd may it’s showing status as ‘Administrative Processing’.
