US Non Immigrant Visa - Admin Processing

I applied for a non-immigration B1/B2 visa to the US in London on an Indian passport. At the end of my interview, the officer informed me that my visa has been approved. But the current status of my application says "Administrative Processing".

Can someone help me understand what does this mean.
Thanks.

Better to consult or ask on the embassy regarding that status. You may also find this link useful for that matter.
