Hi
I am currently working in AAA company in India and it sponsors me for H1B visa last year and the same has been approved in the lottery. And the validity is till Jun'2017. I got only mail intimation about the approval from my current employer.
Visa stamping not yet scheduled and chances are less due to project constraints. I would like to switch my job to company BBB.
My queries:
1) Will BBB company be able to utilize my approved petition and send me to US for work? In this case what kind of documents will they expect from me?
2) As AAA has not shared any document on the petition approval with me (Do not think i will get any such documents from AAA), how i can process my stamping and other related documents with BBB company.
3) Is there any procedure where AAA is allowed to cancel my approved petition if i move out of the company.
Thanks.
