I hold H1B visa and currently working in India for my employer. My visa stamping was done for location, lets say it as A. Due to client requirements, I need to travel to different location, lets say it as B. I have initiated relocation amendment request and it is in progress. Meanwhile I need to initiate H4 visa for my wife. So my query is what US address do I need to mention for my wife in DS 160 ? will it be location A as per my stamping information ? or will it be location B for which relocation amendment is in progress ?
