Another concern is if there are any other options for me to apply. What if I don't live in the United States of America or one of its territories?
You could get in contact with the nearest US Social Security office, US Embassy or consulate.
How would I mail documents to you?
Please include the Social Security number so that we can match them with the right application and do not write on the original documents and write your Social Security number on a seperate sheet of paper.
