No documents asked. At the time of interview she asked couple of regular questions which I answered and she suddenly stuck on my previous visa [B1/B2] cancellation and she asked if it was cancelled bcoz I overstayed!! I told her that its cancelled without prejudice [It was cancelled when hyd consulate issued me L1].
Just to give you background; I used only L1 visa to enter US and later got COS to H1. So I actually maintained my status in US only on L1 and H1. And as far my knowledge is concerned even in petition you supposed to mention beneficiary’s previous stay in US [If any!] and on what type of Visa. No sure if she referred to that info else she would know that B1/B2 was never used by me.
But she wasn’t convinced and and told me to go to another window and wait for instructions. Finally I got 221g white form Indian staff who crossed it [no further documents required], wrote case number took my passport and i797 and told me that it’ll take two week to conclude this process.
Now its almost a week and no status update so far and no communication.
