VISA stamping needed when H1b transfered?

[sandeepnimmala]

I am having valid H1B visa till AUG 2013 with my old company A, recently i have transferred (Got approved) my H1B visa with my new company B. so if i go to India, do i really need to go for H1B stamping again to reenter US or still my old H1B visa with company A will be valid (with approved H1B petition with company B)?

You can use the old H1B visa with the new employer's H1B petition to re-enter U.S.
