As far as I know, I don't think you need a visa to come back to US if you have a valid status here. You can use the I-94 attached on your I797 form to come back. It's called automatic revelidation.

Hopefully this helps. If you are still worried, just call Immigration office's 1-800 number and ask them about it.
