L1, L2 Visa

Dear Friends
I would like to share my experience for L1A Visa. Many posts on these website have been immensely helpful to me and i hope that my post shall help few of the people to get answers to their worries.
My company had applied for L1A individual Visa and the petition was approved by USCIS within 15 days.
After that i filled DS-160 and took appointment for Visa interview at the Mumbai consulate. My finger printing was done on 4th Sept 2015 and it went as smooth as possible and I was out within 5 minutes. Please do not go more than 15 minutes in advance to your appointment time. They only check the passport and the DS-160 confirmation. The entire process took less than 5 minutes.
The main hurdle, the actual interview was on 8th Sep 2015. There was a long queue and after about 35-40 minutes, i entered the consulate. There was a queue and the Indian employees took our passport from us and the fingerprints were verified by US Visa officer. My passport was returned and since mine was L1A Visa, i was asked to keep my 797 ready along with the passport.
Most of the people ahead of me were families and were being interviewwd in groups and from their body language it seemed that there Visas were getting approved, it increased by confidence a bit.
However there was one young girl who was interviewed for almost 5 minutes and i could hear the VO telling her that her Visa is not approved..... I started getting nervous, then came my turn.
I was in front of the VO for barely 50 secs. The interview was as below:
Me; Good morning Officer
VO: Good morning, your passport please
I handed him the passport, the VO was not looking at me, he continued to stare at the computer screen and was typing.
VO: What is your qualification ?
ME: B.TEch
VO: What is your specialization.
ME: Told about my specialization in two words,
VO: OK, i ned more information to approve your Visa,
He handed over my passport and 221(g) green form.
VO: Please provide the information requested in this form. You need not return to the consulate.
I was dejected and then VO looked at my face and smiled.
VO: Do not worry, we shall issue you the Visa once you provide the required information"for Administrative processing""

Naturally, i was very disappointed with this and came back to office with the 221(g).
The information asked in 221(g) was:
1) Invitation letter from my USA company in PDF format
2) Detailed CV, SOP, financial support, details of overseas travel in last 10 years, No. of travellers etc in a word file.

I provided all the information in a single email on email ID provided in the form.
Then started the most difficult phase. There were numerous experiences regarding 221(g) and there were very contradictory. Many ppl mentioned that they had submitted the documents and waiting for months with no update. Few ppl had the result, either approval or rejection in a month or two.
I was very anxious. The websites provide no information regarding the exact time period for the "Administrative processing". I kept on checking in the CEAC site but got same reply.
Finally after three weeks, i got a mail from consulate requesting to submit passport along with copes of 797 and also the documents mentioned in 221(g)
i submitted these docs along with my passport and finally got the Visa stamped.
My advice to people facing 221(g) hardships:
Be patient, even if the CEAC says that it may take several months, it usually takes 15 working days if your documents are in order.
So submit the documents and pray to God.
All the best.
I am flying to USA on 2nd Nov.
