My H1B is due to expire in Sept 09. I had filed for H1B transfer in Jun 08. However, I have not received approval yet. My employer is going to file in premium soon. I want to know if the new approval (if approved), what is the validity period. Is it also going to be valid until Sept 09 ? In that case I may not get sufficient time to file for extension, so I want to be prepared. Thanks for help !
