L1, L2 Visa

First of all thank you for the immihelp website and people those who shared their experiences, Now this is my turn to share my experience.

My Case was like - my B1/B2 VISA application was rejected in past (multiple time) and this time my company applied for L1B Blanket Visa for me.
My last rejection was for different type of visa, so I didn't get any hurdles for L1 visa approval.

I Stayed in Crystal residency hotel, opp. to US consulate chennai, which is good for VISA application people to stay, VFS is also near from this hotel.

My VISA interview time was 11:00AM on 12/07/2016, We ( Me, wife & daughter) reached 30 min. early to the visa interview time, as my daughter was there with us, so we got priority for all processes like, biometric, fraudulant visa fee payment and visa interview, they stich one smily on my passport to get priority to us.
Thanks to consulate people!

I am from manufacturing industry, Swedish MNC and we had our subsidiary worldwide, so my previous travel (VISA stamps from schengen VISA or other VISA's) might helped me.

Documents required are -
I129S 3 copies
I797 blanket petition document (only first page) - 3 copies.
DD of 500USD
DS 160 confirmation page
passports
That's all, I took lots of documents but they have asked to keep only above listed documents.

So the Visa interview was like -

My Visa was on counter number 25, a young 35-40 aged man was there with great smile on his face, He greeted me first as good morning and visa interview started.
