Can I attend H1B visa interview @ chennai if my i797 shows mumbai as consulate??

[venkatrao]

As I need to attend H1B visa interview in the next month. I need a small clarification. Here it follows :

I have received my i797 form, in that form consulate name shows as MUMBAI but i have booked visa interview slot @ chennai consulate.
Can I attend visa interview @ chennai even if my i797 shows as MUMBAI?

If so, Is there any other documents do i need to carry for that ???

Thanks in advance
