I am presently in India. My company filed h1 for me and i got it approved in May 2012. Unfortunately there are no requirements in my project right now and so I am planing to move out of my company since my spouse is i the US. My company has agreed to provide me my approved H1 petition copy(scanned copy). Can I use this petition and do a transfer or amendment to another employer if i find a job over there (US) ? In what all ways will this be useful for me if i find a job in the US?
