Can you tell me what he needs to include with the documents?
If you are planning to mail documents to us, you must include the Social Security number so that we can match them with the correct application. Do not write anything on the original documents. Please write the Social Security number on a separate sheet of paper and include it in the mailing envelope along with the documents.
What if I don't want to send you these documents by mail?
Then you may bring them to a Social Security office. Do not mail foreign birth records or any documents from the Department of Homeland Security DHS, formerly the Immigration and Naturalization Service INS, especially those you are required to keep with you at all times.
