U.S. Citizenship and Immigration Services (USCIS) has reinforced its use of neighborhood investigations in certain naturalization cases, giving officers another way to verify information provided by people applying for U.S. citizenship.
The August 25, 2026 USCIS policy update is important, but it is not an entirely new policy. It builds on a USCIS memorandum issued in August 2025 that ended the agency’s longstanding general waiver of neighborhood investigations and brought personal investigations back into the naturalization process.
The latest guidance incorporates the practice into the USCIS Policy Manual and emphasizes the agency’s authority to verify information and documentation during the naturalization examination.
What are USCIS “Neighborhood Investigations” for Citizenship?
A neighborhood investigation, also called a personal investigation, allows USCIS to gather information to help determine whether a naturalization applicant meets the requirements for citizenship.
The legal authority comes from Section 335(a) of the Immigration and Nationality Act (INA). USCIS’s August 2025 memorandum explained that these investigations cover the vicinity of an applicant’s residence and employment and include at least the five-year period before the naturalization application was filed.
The purpose is to corroborate eligibility for naturalization, including matters such as residence, good moral character, attachment to the U.S. Constitution, and disposition toward the good order and happiness of the United States.
This is different from the standard background checks that are already part of the naturalization process. USCIS generally collects biometrics and uses FBI background checks, while the naturalization interview allows an officer to review the N-400 and question the applicant about their application and background.
A neighborhood investigation gives USCIS another method of independently verifying information.
Why is USCIS using these investigations again?
For decades, USCIS generally waived the personal investigation requirement. The August 2025 memorandum changed that approach, and USCIS said the August 2026 guidance was based in part on the agency’s experience conducting investigations since the policy was revived.
The latest guidance therefore should not be understood as a new requirement that every citizenship applicant will face. USCIS describes personal investigations as an adjudication tool that can be used to further assess and corroborate naturalization eligibility.
The agency’s authority is also not unlimited. The investigation must relate to determining whether the applicant satisfies the legal requirements for naturalization.
What can USCIS investigate about a naturalization applicant?
The investigation can involve information connected to the applicant’s eligibility for citizenship. Depending on the circumstances, this can include:
- Current and previous residences
- Employment history and places of employment
- Residence and physical-presence history
- Information provided on Form N-400
- Statements made during the naturalization interview
- Information relevant to good moral character
- Other information that may help USCIS determine whether the applicant meets the requirements for naturalization
USCIS’s 2025 memorandum specifically described investigations around an applicant’s residence and employment and at least the five years preceding the N-400 filing.
The relevant period can also depend on the naturalization category and the requirement being examined. For example, most applicants applying through the five-year lawful permanent resident route must demonstrate continuous residence for five years and physical presence in the United States for at least 30 months during that period. Applicants using the three-year marriage-based route generally have different requirements.
What can cause problems during a Neighborhood Investigation?
The investigation itself does not mean an applicant has done anything wrong. Problems can arise when information USCIS obtains does not match the applicant’s N-400, supporting evidence or answers during the interview.
Examples can include:
Inconsistent addresses or dates. A residence history that does not match other records can raise questions about where an applicant actually lived and whether continuous residence and physical presence requirements were satisfied.
Undisclosed employment. Employment that was omitted from the N-400 or described differently elsewhere may require an explanation.
Contradictions. Differences between an applicant’s answers and information USCIS obtains from other sources can lead to additional questions or investigation.
Criminal history or other conduct. Certain criminal conduct can affect eligibility or good moral character. USCIS’s N-400 instructions specifically tell applicants to report offenses, including certain offenses that were expunged or occurred before the applicant turned 18.
Tax problems. Failure to pay required taxes can affect a good moral character determination. USCIS may request tax records and evidence of an agreement to repay overdue taxes.
Immigration violations. Past immigration violations or inaccurate information in previous immigration applications may become relevant when USCIS evaluates the naturalization application.
False statements or omissions. Leaving out information or providing false information can create a much more serious issue than an ordinary mistake.
USCIS has also placed greater emphasis on a broader, holistic evaluation of good moral character. Its 2025 guidance states that officers should consider both negative conduct and positive attributes, including community involvement, family responsibilities, education, lawful employment, length of lawful residence and compliance with tax obligations.
Can you avoid a USCIS Neighborhood Investigation?
There is no guaranteed way to avoid these checks. Under the new policy, USCIS retains full discretion to choose which applicants it investigates. In practice, that means:
- USCIS does not promise to skip investigations for certain groups. Don’t be lured by rumors like “If you’ve never been arrested, they won’t check.” There is no published checklist of triggers. According to USCIS guidance, the agency’s security unit will look at the facts of each case and decide whether an investigation is warranted. It’s entirely possible – even likely – that any case could be selected, especially if there are any red flags in the file.
- Applicants cannot demand a waiver upfront. Under the rule, the district director may waive the investigation for particular cases, but there is no applicant right to a waiver. You could politely request one, but ultimately it’s USCIS’s call.
- Not cooperating may invite scrutiny. The policy highlights that if you ignore requests for information (like character letters or evidence), USCIS is more likely to proceed with a field investigation. In other words, being unhelpful doesn’t make USCIS forget about the case – it may push them to dig deeper.
The best approach is proactive preparation rather than avoidance. A fully honest, well-documented application may never need a neighborhood visit. In fact, USCIS encourages applicants to submit high-quality character reference letters and documentation before an investigation is launched.
These letters (from non-family U.S. citizens who know you) and solid records can sometimes persuade USCIS that an in-person check isn’t needed. But even this isn’t foolproof – USCIS says it will consider letters among all evidence in deciding whether to waive the investigation.
Bottom line: There’s no hack to skip this step if the agency chooses to use it. The only way to minimize risks is to give USCIS every reason to trust your application upfront. That means being thorough and truthful (so there are no surprises) and furnishing any helpful evidence (like letters or proof of good conduct) early.
Applicants also should not change their living arrangements, employment or other circumstances simply to try to avoid scrutiny. The goal should be accuracy, not attempting to influence whether USCIS decides to investigate.
How to prepare for a USCIS Neighborhood Investigation
Before filing Form N-400, applicants should consider reviewing:
- Residence history: Confirm addresses and dates for the required period.
- Employment history: Make sure employers, positions and dates are accurately reported.
- Travel history: Review trips outside the United States and physical-presence calculations.
- Previous immigration filings: Check older applications for information that could conflict with the N-400.
- Tax records: Make sure tax filings and payment arrangements accurately reflect your history.
- Criminal or court records: Review any arrests, charges, convictions or other relevant matters.
- Naturalization answers: Be prepared to explain information on the N-400 consistently during the interview.
The point is not to prepare for what a neighbor might say. It is to make sure the information USCIS is reviewing is accurate and can be supported if questions arise.
What happens if USCIS finds a problem?
A concern discovered during an investigation does not automatically mean that a naturalization application will be denied.
Depending on the issue, USCIS may seek additional evidence, ask follow-up questions, continue its investigation or take additional time to adjudicate the application. If USCIS determines that the applicant has not established eligibility, the N-400 could ultimately be denied.
The consequences depend heavily on the underlying issue. A simple discrepancy may be explainable or correctable. A concern involving fraud, false testimony, certain criminal conduct, tax problems, unlawful voting or a false claim to U.S. citizenship can be significantly more serious.
If an applicant receives a request for additional evidence, receives a notice of intent to deny, or is concerned about information in their immigration history, speaking with an immigration attorney before responding can be important.
A denied naturalization application does not necessarily mean the applicant can never become a U.S. citizen. Whether the person can reapply, appeal or pursue another option depends on the reason for the denial and the applicant’s circumstances.

Frequently Asked Questions
Can USCIS visit my home for citizenship?
USCIS has authority to conduct personal or neighborhood investigations in connection with naturalization applications. The policy does not mean that every applicant will receive a home visit. Investigations are discretionary and can be used to verify information relevant to eligibility.
Does USCIS interview your neighbors for naturalization?
A neighborhood investigation can involve gathering information from people or sources connected to an applicant’s residence or employment. However, USCIS has not stated that every naturalization applicant will have their neighbors interviewed.
What does USCIS ask neighbors?
The specific questions can depend on what USCIS is trying to verify. The investigation is intended to help corroborate information relevant to naturalization eligibility, including residence, employment and good moral character.
Can USCIS investigate my previous addresses?
Yes. USCIS’s policy describes personal investigations covering the vicinity of an applicant’s residence and employment, including at least the five-year period before the naturalization application. The applicable period can vary depending on the naturalization category and requirement involved.
Can USCIS investigate my employer for citizenship?
USCIS’s policy specifically identifies the vicinity of an applicant’s employment as part of a personal investigation. Employment history can also be relevant to information provided on the N-400 and to the overall naturalization examination.
Can a neighbor cause my citizenship application to be denied?
A neighbor’s statement alone does not automatically determine whether an applicant qualifies for citizenship. USCIS must evaluate the information as part of the overall naturalization adjudication and determine whether the applicant has established eligibility.
How do I prepare for a USCIS home visit?
There is no special procedure that guarantees a home visit will not occur. The most useful preparation is to ensure that your N-400, supporting documents and answers accurately reflect your residence, employment, travel and immigration history. If there are potential inconsistencies or complicated issues in your history, consider addressing them before filing.
