L1, L2 Visa

Hi All,
I have been using this site for years for immigration and visa related information. So I did again before my interview this time.
I have been in US on L1B visa with my family for long term earlier and my company applied again. Me, my wife and son appeared for interview at Chennai US consulate and here is the detail of interaction with VO:

Me: Good morning mam, How are you today?
VO: Good, how are you?
Me: Wonderful!!

VO: Who is your petitioner?
Me: It’s my company “xxxxxx” (I had in mind if later she asked the name of person, I was ready to say the name on 129s petition)

VO: So you have been there at this site before?
Me: Yes Mam, I have been there on L1B visa last time.

VO: Is this a client site or your company’s office?
Me: It’s my company’s office.

VO: Where is it located?
Me: xxxxx

VO: What is that again?
Me: I started repeating and she asked if that was xxx then what? I repeated it is xx(Seemed like she was hearing the name of this place first time).

VO: OK, so is that in Maryland?
Me: Yes Mam, May be you know Baltimore, it’s there.

VO: So city name is xxxx?
Me: Yes Mam.

VO: So what you do?
Me: I design and develop our company’s xxx machines, This is the machine which converts xxxx to yyyy, It is very high speed and highly advanced machine.

VO: What this does again.
Me: It processes the xxxx and converts them into yyyy.

VO: Oh, so you design machines to produce yyyy and not that you make the yyyy.
Me: Yes Mam, our customers who buy these machines they make yyyy using our machines.

VO: Was your wife with you when you were there last time?
Me: Yes Mam.

VO: So can you show me the last VISA stamping, old passports of your son and yourself?
Me: Took out the old passports from Bag and showed the last L2 and L1 visas for my son and myself.

VO: So your last visa was issued in year xxxx, where are the VISA stamping for your son and wife for that year?
Me: Explained that I had visited India alone leaving my family in US for short trip so they don't have new stampings but I have all of the extension approvals.

VO: OK, fine. (after having look on old Visas and typing something for 20 seconds on her PC she returned the old passports).

VO: So how many kids you have? I see one here.
Me: Just one Mam.

VO: (Started stamping I129s for approval and told that your visa is approved) I am returning you two copies of I129, provide one copy to your CPD and keep one copy with you for travel and have a good day.
Me and my wife: Thanks a lot and you have a good day too.

(She didn’t ask anything from my wife or son).

Hope it helps readers!!
have a good day!!!
