My wife received her visa and passport a week ago Alhamdulillah. There was a letter in the envelope with instructions to pay the immigration fee, we got that taken care of. But, it also says in the letter that she has to take her x-rays or CD with her to the US as it is required at US immigration. However, she wasn't given anything after her medical exam, so I'm thinking that everything was transferred electronically. Just wanted some insight on this. Does she have to do anything else, or is she okay with just her passport and visa?
