H4 Stamping when transfer in progress

I did H1 transfer recently and approved. I have applied for H4 transfer and still waiting for receipt. We are planning to visit India this summer. We have to go for stamping. Do we need to wait for the approval of the current extension or Can I go for stamping using my approved petition?

You can visit US embassy and get H4 visa stamp using H1B’s approved i797. No need to wait for pending H4 extension/transfer.
