I have aproved H1B petition. It was aproved (not stamped till date) in february,2012. But due to lack of opportunity with Company A, I could not travel till date. I have few questions
1- Is H1B aproved petition transferable ?
2- If yes what is the procedure ?
3- Is there any expiry date of aproved petition. I heard it will expire in March,2013. What does that mean and how can one save it.
Your reply is awaited.
