There are only certain documents that we can use for verifying your U.S. citizenship, like your U.S. passport.
I don't have a passport and have lived in the U.S. for many years. What else can I use?
In this case, you may be asked to submit copies of your tax records that show you were never given a Social Security number, or information about schools that you've attended.
Will you accept photocopies of the documents I need?
