We finally have our interview date for my wife at Ciudad Juarez. Providing the interview goes well and they accept us, when do they give us the visa to enter the US? Some people have said they mail it to you via courier, others have said they hand it back to you with the visa right then and there. We're trying to get an idea as to when/which day she can come back with me to the US. Also, i will be will my wife in Juarez, but will I, the petioner, be a part of the interview as well? Thanks!
