L1A visa extn stamping appointment reschule

hi, my L1 A visa was renewed in February 2025 (original L1 A was till July 2025) and have the approval notice with new date. I was not sure if I need the L1 A renewal visa stamp but now I have got the OFC date of Oct 15th and Visa interview date of Nov 7th.

Q1) in this case do I need a L1A visa renewal stamp?

Q2 ) if so, is it possible to change only the Visa interview date to bring it closer to my OFC appointment date?

If you are already in the US, you don’t need a visa stamp unless your current visa is expired and your plan to travel outside of the US
