USCIS has revised its rules for filing N-400 naturalization applications, stating that applicants no longer need to submit two passport-style photographs with their applications. Fingerprints, photographs, and signature will be taken at scheduled biometric service appointments.  Biometrics will now be required regardless of age.  On a related note, naturalization applicants are reminded that during the pendency of their case, they are required to file a Form I-90 to renew their permanent resident card if it is expiring.
