Multiple H1 and re-entering from India

[newmember]

Hi all,
* I am in the US and I have a valid H1B from my current employer and my passport has been stamped for this H1B.
* I have a job offer from another company and they have filed for my new H1B.
My question is :
1) When will the H1B from my current employer expire?
2) I the time between filing for a new H1 and getting an approval notice (which I believe would take 3-4 weeks???), I want to travel to India. When I returned back, can I return back with my original employers H1 B stamp on my passport?
3) Will there be a problem re-entering, as in is it likely that I will be questioned about a new impending H1B?
Thanks a lot in advance for the great help!

Your H1 stamp is valid even after you join new company. You can enter any time until expiration of H1 stamp and with new company's H1 approval notice.
