b1/b2 Administrative Processing with form 221g (Blue Slip)

[ihussain]

Hi All,

I appeared for b1/b2 visa interview on 20/9/2016 at Chennai cosulate and below were the questions asked to me during the interview.

1. Purpose of visit - Answered
2. Place of Visit - Answered
3. Duration of stay - 3 weeks
4. What are my roles in my current comapny - Answered
5. Have I ever visited any other country ? - No
6. Am I married ? - No

I answered these questions properly and at last consular gave me a blue slip marking the point on it which says "your case requires additional admisnistrative processing before a final decision can be made" and he handed over me the form. He kept my passport and said if they need any information they will ask over mail.

As of now status still says "Admisnistrative Processing" with no mails or notifiaction. Can anybody help to what all these means and how long it will take to come to a final decision ?
How much are the chances of getting it approved ?

Thanks in advance !
