H1B, H4 Visa

Hi everyone!

Thanks so much for sharing your experiences till now. This has been such a learning curve and helped me prepare.

I went for visa interview today at 11am to New Delhi Consulate. I got inside within 30 min, from check-post to the interview counter number. VO was denying / delaying the visa for the girl ahead of me so she kept pleading. I was nervous and was thinking of moving to another window. However, I was called soon.

VO: Which company do you work for?
VO: What is your position? (I explained the position I will be joining into, based on the approval. I did not bring up my current position to keep things simple. This was first time for H1B stamping; and it was with visa amendment without I-94.)
VO: Is this your first time going to the US?
VO: Oh, you did your master in xxx city? How did you find it?
        I was there for my degree from 20xx-20xx. (We kind of connected at this point.)
VO kept looking into paperwork for a minute. I kept my mouth shut.
VO: When do you plan to go to the US? (I mentioned May 1st week if I receive my passport back in time. No tickets booked yet.)
VO: Show me your I-797 and old passport. (I provided. He handed both back after looking at those.
VO: Your case has been selected for Admin Processing (handed me giving you a yellow 221g slip). Everything is alright in your application. You are a great candidate. But your case will be further review by Washington. This will take some extra time, 3-4 business days.
(I asked is this meant 2 weeks for processing, since regular processing still takes 3-4 business days).
VO: It should be a little less than 2 weeks. No documents are required from your side.
(I asked if my company or I will receive request for documentation later. And what would these documents be.)
VO: Everything in your application is alright. No documents are required.

I am confused why the yellow slip was given.

My background:
I got H1B in 2016-17 lottery, but changed positions soon after. The company filed later for the amendment, and RFE was issued if I maintained status. The company withdrew the petition because they didn't want the petition to result in a denial. The company filed another petition with consular processing this time.

Currently, my passport status is "Your passport is still with the US Embassy/Consulate", and my visa status is "Admin Processing". Case was created on April 21, and Case Last Updated on April 24.

I am in a limbo. I am working from India for the last 1 month and my company expects me to get back next week, which seems impossible.

I am wondering at this point:

1. How long do you think it will take for me to get the final visa approval? Can I trust the VO, or it routinely takes 4 weeks at the least?

2. Do you think Washington will ask for documents, even though the VO has not? Is it common to not specify which documents they need during the interview, but they follow up via mail?

3. Is there any trouble, because of potential out of status period?

Thanks so much!!
