H-1B extension pending: Impact of traveling to India using old visa, returning with 2-3 days remaining on visa, etc.

Question details

My current I-797 and H-1B visa stamping is valid until 03rd December 2024. I have filed for an extension. Can I travel to India while my H-1B extension is pending? Does it have any impact on my I-797 approval and its validity period, as my I-94 will be changed upon my reentry to the USA?
I am traveling to India for Medical reasons in the month of September and will return on December 1st, 2024. If my H-1B is not approved by December 1st, Can I enter the USA with 2-3 days of Visa stamp validity, and what justification could I give with only 2-3 days of stamping validity?

If my H-1B is approved while I am out of the country or during transit, Can I enter the USA with the existing H-1B stamping?

My work is remote, and I can work from anywhere. Can you provide me with a better solution than the 2 options below?

1. If my visa is not approved by then, I will travel to India and return to the USA before December 1st.

2. I will continue to stay in India until I get my visa approved and get the stamping done before reentry to the USA. Premium processing is no option for me as my employer will not support citing RFEs as the reason.

If you have an H-1B visa from a previous employer that hasn't expired and your current employer has filed for an extension, you can travel outside the U.S. while the extension is pending. You can return with just a few days left on your old visa stamp. The visa is not tied to a specific employer, so as long as your old visa is valid, you should be able to re-enter the U.S.

However, it's important to carry proof of your pending extension when you return. While there is no official source confirming this, many individuals have successfully traveled under similar circumstances without issues.
