Here is an update from USCIS:
We would like to share two important updates to filing Form N-400, Application for Naturalization, now that it is processed electronically. All applicants (except those who reside overseas):
- No longer need to submit two passport-style photographs. We will capture their photographs when they appear at the Application Support Center (ASC) for their biometrics appointment.
- Will be scheduled for a biometric service appointment at a local ASC for collection of their fingerprints, photographs and signature, regardless of their age.
USCIS used to waive the fingerprint requirement for applicants 75 years or older, which meant they were not required to appear at an ASC. However, now that this form is processed electronically, those applicants do need to appear at an ASC. Our improved technology means we can capture fingerprints for applicants of all ages. This enhances our ability to confirm their identity and perform required background checks. We will update the form instructions, Policy Manual and Guide to Naturalization as soon as possible. Applicants aged 75 and older do not have to pay the biometrics fee.
All domestic USCIS facilities are accessible to individuals with disabilities. However, USCIS can make special arrangements to accommodate the needs of the elderly and applicants with disabilities, who are homebound or hospitalized. This is known as homebound processing<my.uscis.gov/helpcenter/article/what-is-homebound-processing. Applicants who need to request an accommodation<uscis.gov/tools/requesting-accommodations-disabilities for their appointment can submit a service request<egov.uscis.gov/e-request/Intro.do online or call the National Customer Service Center (NCSC) at any time at 800-375-5283 (TDD: 800-767-1833).
