L1 A blanket visa and OFC appointment

[vidu.s]

Hi,

I booked my L1 A blanket visa extension appointment with Chennai consulate in Nov. When I was booking the OFC appointment, it gave me a dropdown to select OFC of my choice and I selected Mumbai, since I'm from there. Is this ok? Or do I have to change my OFC appointment to Chennai. It won't allow me to change unless I cancel my existing appointment. Since I found dates for Nov after a number of attempts, I don't want to lose my existing appointment, if the choice of OFC location is not an issue.

Can someone please advise?

You can go for OFC in Mumbai. No problem.
