H1-Transfer - stamping

[mickyblue824]

I have a visa stamping in my PP under company-A. I've had a H1 transfer to company-B. Do I need a new stamping in my Passport? If not, if I go abroad now and return, would I be facing any questions at the immigration if I dont have a new stamping.

Thanks,

Show valid stamp w/ A and approval notice with B upon reentery. No problem.
