H1B Interview-No Slot available in Chennai

Hello folks,

I’m trying to schedule an appointment for visa interview in Chennai but it says currently no slots available.
Is this normal ? and my home address is in Karnataka so I’m supposed to go to Chennai consulate.However,there are interview slots available in other locations for August/September.So can I book an interview in Kolkata or other locations?
And if I schedule an appointment how many times can I change it?

Thanks,
Sunil

It is normal, sometimes, the consulate can be very busy. You are free to go to any other locations and give interview there. You can change it up to 2 or 3 times I think, just double check. You can call them or chat with customer support.
