⟩ In the h1b document they have mentioned the interview location as Chennai by that time Hyderabad office was not opened. can any one help me where i can attend the interview Hyderabad or Chennai and is it the right time to attend the interview?
i think u have to visit the same consulate as mentioned in
your h1b approval. If you want to change the consulate then
u have to get back to USCIS which will take around 3/4
months to change the consulate area.
