I am currently on H1b work visa. My stamped H1b visa through previous employer expires Sept 2016, I changed employers during 2011 and new I797 issued to me expires on April 2017 (3 years from date of issue)
So when should I file extension of my H1b visa, is it by considering Sep 2016 as expiry date or April 2017 as expiry date.
I may need to travel on business out of US and if I have to travel after Sept 2016 I am afraid I have to go for H1b stamping, do I need to have my H1b extension approved before I travel out of US between Sept 2016 and April 2017 timeframe?
Thank you very much for your help.
