If your immigration status changed or you became a U.S. citizen, you should tell Social Security so your records can be updated. To get your immigration status or citizenship corrected, you need to show documents that prove your new status or citizenship. Only certain documents can be accepted as proof of citizenship for new and replacement cards. These include your U.S. passport, a Certificate of Naturalization or a Certificate of Citizenship. If you are not a U.S. citizen, Social Security will ask to see your current immigration documents.
