I was given 221(g) post my Visa interview (b1/b2) at Chennai stating it needs some additional processing. The office said he cannot commit on the timelines. He retained my passport too,
10-Sep-2018 – Interview followed by handing over of 221(g)
10-Sep-2018 – Status updated in the portal as “Administrative Processing”
14-Sep-2018 – Status Updated and still shown as “Administrative Processing”
20-Sep-2018 – Status updated and shown as “issued”
24-Sep-2018 – Received the passport today with 10 years of Visa stamped
Here is a good read on the administrative processing:

I know a few friends who have had administrative processing for other VISA categories (H1). It has taken up to 4-5 weeks from my knowledge. Also, certain conditions by default put you under administrative processing. For e.g. :
1) Your Name
2) Your job description.
I am well aware that both the above reasons can get you in for background checks / administrative processing.
Since yours is a B1/B2 category VISA, there is no reason to worry till your administrative processing has come back with a decision.
