L1, L2 Visa

I had my L1A intv on June 15 @8:30AM in Mumbai. I went there with my wife. I was very sceptical as my earlier L1B petition had been denied but a subsequent L1A petition was approved. We had to wait for almost 4hrs for the intv which took place around noon. Before my intv, there was 1 guy with L1B blanket petition and it was approved as well

VO: Good Morning
Me: Good Morning
VO: How long have you been married
Me : YYYY yrs
VO : Any kids
ME : XX
VO : How much will you be paid
Me : XX
VO : Will that be enough? Asks my wife
Her : I guess so.
VO: He laughs. Says it should be enough
VO: What's ur designation
ME : I am lead project manager .....
VO: Ok OK. <cuts me in middle> Your visa is approved. Have a nice time

It all finished in 2 mts after a wait of 4hrs. I was scared about all sorts of questions esp how I filed for L1A immediately after L1B denial. But I guess, US visa people have their own yardstick..

My suggestion : Some preparation does help. Helps you to be confident.
