L1 extension docs submitted with old address

[Ajayesh]

Hello,

I had filed my docs for L1 visa extension processing at USCIS and am in urgent need of approval to travel back to India. I forgot to update that with my new residential address at US.

How serious is this?
How to make the corrections?
How much would be the delay caused?

Thanks in advance.

How long can this affect the processing? Please advise.

Thanks.
