hey girl up here in AK they only asked for his passport and the I90 which he didn't receive so the associate just input the application in and gave us a paper with the number on it and said his ssn card will be in the mail in the next 30 days
My husband brought his K-1 visa/Passport with him to the Social security office. It was a pretty quick process. After giving them his information they mail it to us in less than a week.
