L1, L2 Visa

The overall process is smooth if you are prepared well in terms of your documentation ! Chennai is the only centre in India to provide this type of visa.
Book flights and hotel in advance - Google is your best buddy here, choose whatever suits you best.

Day 1: Biometrics - Docs needed: Appointment Letter, Passport and DS160 confirmation. If you have kids take photos of them from the shop at the ground floor.
Day 2: We reached the Consulate 15 minutes prior to the appointment and were let in pretty quickly as we had an Infant with us too. You start with the security check (Mobiles, smart watches are not allowed, best to leave them at the hotel). After security check > You will be directed to a team that will arrange your docs > Order of docs : I129 - I797 - Passport of main applicant followed by dependents. Then you move in line to pay the fraud fees > $500 (Best to carry credit card as exchange rates can fluctuate and DD may not be best for this). You can see others being interviewed while you wait to pay the fraud fees.

Now I was in line for the interview, I called my wife along with my son and we stood in line.

We: Thank you Officer, You have a great day ahead

If you are what you say you are - Just be your self and there is nothing to worry about
Plan your next day, be it biometrics or consulate visit - Prepare docs, Credit card before hand. If you have everything thats needed, that inturn will boost your confidence for sure and will avoid last minute hassle.
