Starting April 1, applicants filing Form N-400, Application for Naturalization, can now request an original or replacement Social Security number (SSN) or card and update their immigration status with the Social Security Administration (SSA) without visiting an SSA office. Noncitizens using the new edition of Form N-400 (dated 04/01/24) can request an SSN or replacement card alongside their application submission. New citizens may avoid the need to visit an SSA field office for these purposes.
