My wife is currently in india and will accompany me to the USA after the CP interview. So in her DS 230 I form she has mentioned that she has never visited the USA. But, for some unforeseen reason (NVC delay, change in policy from aug 1, etc.), if the interview gets delayed by couple of months, will she be able to come to the USA and then send the updated DS 230 part I form with her visit information to the consulate?
