On August 25, 2026, USCIS updated its Policy Manual to reinforce its authority to conduct neighborhood investigations of applicants seeking citizenship through Form N-400. The agency may contact neighbors, landlords, employers, coworkers, and business associates, generally covering the five years before an application is filed.
Why it matters
The guidance clarifies how far the naturalization review can reach into an applicant's personal and professional life. Applicants may be asked to submit testimonial letters, though submitting them does not guarantee an exemption from investigation.
The guidance is an agency policy update rather than a statistical release, and it sets a typical look-back period of five years before the citizenship application is filed. The data does not show how many investigations are conducted or how often testimonial letters lead to waivers.
The players
U.S. Citizenship and Immigration Services (USCIS)
The federal agency within the Department of Homeland Security that administers immigration benefits, including naturalization, and issues the policy guidance governing how applications are reviewed.
The details
USCIS has discretion to decide whether an investigation is necessary after reviewing an applicant's file. If unfavorable information could lead to denial, the agency must notify the applicant and give an opportunity to respond, and it makes the final decision based on the evidence and individual circumstances of each case.

Five years before filing: the typical period covered by a neighborhood investigation.
Big Picture
The update reinforces investigative authority already set out in the USCIS Policy Manual's naturalization provisions, rather than creating a new procedure. It signals how the agency intends to apply that authority to Form N-400 applicants.
Applicants for citizenship through Form N-400 may be contacted by USCIS for information from neighbors, landlords, employers, or coworkers. Gathering testimonial letters from people who know you can help, but it does not guarantee that the agency will skip an investigation.
The takeaway
Naturalization applicants should expect that USCIS may look beyond their paperwork to the people in their daily lives. Keeping accurate records of residence, employment, and community ties over the prior five years can help when responding to any follow-up request.
