USCIS Resumes Neighborhood Investigations in Naturalization Cases

USCIS has announced a significant change to the naturalization examination process: officers may once again conduct neighborhood investigations to verify information provided by applicants for U.S. citizenship.

In Policy Alert PA-2026-10, USCIS updated its Policy Manual to reinforce the agency's authority under INA § 335(a) to investigate an applicant's residence, employment, and good moral character as part of the naturalization process.

The development reflects a broader shift toward more extensive verification of information submitted by naturalization applicants.

What Is a Neighborhood Investigation?

The law has long authorized USCIS to investigate an applicant's eligibility for naturalization beyond the formal review of the N-400 and the naturalization interview.

A neighborhood investigation may involve inquiries directed to individuals who have relevant knowledge of an applicant's circumstances, including neighbors, employers, landlords, or other community contacts.

The purpose is to assist USCIS in verifying information relevant to the applicant's eligibility for citizenship.

Although this authority has existed for decades, it has not been a routine feature of most naturalization cases in recent years. The new policy alert signals that USCIS is again placing greater emphasis on this investigative authority.

What Does This Mean for Naturalization Applicants?

The underlying statutory requirements for naturalization have not changed. Applicants must still satisfy the applicable requirements concerning lawful permanent residence, continuous residence, physical presence, good moral character, attachment to the principles of the Constitution, English and civics requirements, and other statutory and regulatory requirements.

What is changing is the degree to which USCIS may independently verify an applicant's representations. An officer may seek to corroborate information concerning matters such as:

• residential history and continuous residence;

• employment history;

• marital and family history;

• physical presence in the United States;

• good moral character; and

• other information relevant to the applicant's eligibility.

For some applicants, this additional verification may result in a more extensive examination or additional processing before USCIS reaches a final decision.

Accuracy and Consistency Are More Important Than Ever

The policy change underscores an important principle in every naturalization case: the N-400 should be accurate, complete, and consistent with the applicant's immigration history.

Applicants should carefully review the information they provide to USCIS against prior filings and records, including previous Forms N-400, I-485, I-130, I-765, visa applications, and other immigration filings, as applicable.

Particular attention should be given to address and employment histories, marital history, international travel, and matters that may bear on good moral character.

An inconsistency does not necessarily mean an applicant is ineligible for naturalization. However, unexplained discrepancies can create questions that may require additional documentation or explanation.

Good Moral Character Requires Particular Attention

The renewed investigative authority is especially relevant to the good moral character requirement.

Applicants should disclose potentially relevant issues to immigration counsel before filing rather than attempting to determine on their own whether an incident is too minor or too old to matter.

Depending on the circumstances, matters involving arrests, citations, criminal charges, tax issues, immigration violations, misrepresentations, or other conduct may warrant careful review before a naturalization application is submitted.

The objective should not be to conceal an unfavorable fact, but to ensure that the application accurately presents the facts and, where appropriate, provides the documentation and legal context necessary for USCIS to evaluate them correctly.

What Applicants Should Do Now

Applicants preparing to file for naturalization should take several practical steps:

First, review the N-400 carefully. Every answer should be accurate and complete. Second, reconcile the N-400 with prior immigration filings. Address, employment, travel, marital, and other biographical information should be reviewed for potential inconsistencies.

Third, identify potential good-moral-character issues before filing. Applicants should discuss arrests, criminal matters, tax concerns, immigration violations, or other potentially significant issues with qualified immigration counsel.

Finally, do not assume that the naturalization interview is the only source of verification. USCIS now has expressly reaffirmed its authority to conduct community-based inquiries when appropriate.

The Bottom Line

USCIS's resumption of neighborhood investigations does not create new substantive eligibility requirements for citizenship. It does, however, signal a more rigorous approach to verifying the information provided by naturalization applicants.

Applicants should therefore approach the N-400 as more than a form to complete. It is a representation to the federal government that must withstand scrutiny against the applicant's immigration records, personal history, and other available information.

For applicants with straightforward histories, the change may have little practical impact. For those with discrepancies, complicated residence or employment histories, prior immigration issues, or potential good-moral-character concerns, careful preparation before filing is increasingly important.

Our firm is closely monitoring USCIS's implementation of this policy and will continue to assess how neighborhood investigations affect naturalization adjudications in practice.
