1. My H1 Visa from employer A was valid from Nov 2008 till Sep 2010.
2. I changed from employer A to employer B (Current employer) in July 2010. My H1 petition was transferred and extended for employer B. New H1 petition and I-94 are valid till March 11, 2013.
3. My employer A offered me a job in Jan 2013. Employer A filed for my H1 transfer (and probably extension as well) in premium processing. There was an RFE and we are responding to it now.
4. Since my H1 petition is valid till March 11, 2013; my current employer is insisting to submit the documents for H1 extension. My current employer will file for my H1 extension by normal processing in February 2013.
As my H1 extension is already filed by employer B, can I work for him after March 11, 2013 to serve notice period?
