I am an Indian citizen, working in Malaysia. Recently, my H1B case was approved FY2022 and in the I-797B notice it was mentioned Consulate as HYDERABAD in India. However, I am residing in Malaysia as an Employment Pass holder, can I attend the visa interview at US Embassy in Malaysia?
If the US consulate in Malaysia allows TCN (3rd country nationals) for H1B stamping then you can schedule the visa interview at the nearest consulate. It is not mandatory to go to the consulate mentioned in the petition.
Call or email the consulate to check if they will allow TCN.
