How soon before my old H1B visa stamp expires can I stamp my new H1B visa?

Hi, my H1B visa from previous employer expires in Aug 2015. I am travelling to India in March 2015 (5 months before expiry) and would like to stamp the new H1B visa from my current employer (so that I dont have to travel to India again). Can I do this? I have been employed by the new employer for 9 months now and have the necessary documentation.


Why do you need to travel India again? I didnt get your point here. Are you thinking that you MUST have a visa stamped after joining the new employer? Please explain your reason to get visa stamping?

I have commitments to visit India in March and Europe in September. Since my visa expires in August, I need new visa to return to US in September.
