Hi Friends,
Please help. I did try to find this on this website with no luck. Please point me to section explaning this in detail,if any.
I have got my H1 approval (I-797) in Sept 2007. Then i went to us embassy (India - Chennai) where they have asked to submit some more documents (like client letter and agreement) by giving me 221g form. I never replied to the query. But soon after i came to US through B1 Visa (valid till 2012) on Dec 2007 (I 94 valid till feb29, 200

. After getting here without my notice my employer filed for status change and I got my new I 797 with new I 94 (valid till Sept 10, 2010). I am working since then without any issues. Could you please help me with the following questions.
1. Now I am going back to India for vacation. While getting back I need to go to embassy for stamping. What type/kind of questions arises?
2. what kind of documents do I need to submit.
3. if they refused to give me visa then what are my other options to come here? Do i need to apply a new H1B or can I come here through B1 Visa again (since it is valid till 2012)
