qqp question1: My Petition for I_129 (H1B) case was approved on August 6 2013, I just wanted to know till when this petition is valid? question2: I have an approved H1B Petition filed from company A. I have not yet traveled (I am in India) and its not yet stamped. Is it possible to use the approved petition for visa stamping for another employer? If yes- what is required and how can it be done? Can I get a contact who can help with this?
