H1-B transfer and stamping

Currently I am on H1B visa with company A. I have taken appointment for stamping in India on H1B with current employer A.
I have new offer from employer B who is transferring my H1B in premium.
Planning to travel to india after h1b transfer and get stamping for new company B.
What if I am still working for Employer A when I give my passport for stamping ? Will there be any issues if i say that planning to join new company B after return to Usa?
