What Is Form N-400?

Form N-400, Application for Naturalization, is a document used by lawful permanent residents (Green Card holders) in the United States to apply for U.S. citizenship through the process of naturalization.

Submitted to the U.S. Citizenship and Immigration Services (USCIS) by mail or online, 90 days before the requirement for continuous residence, the Form N-400 serves as a formal request to the USCIS to consider your application for U.S. citizenship.

The Form N-400 requires you to provide information about your immigration and employment history, along with any criminal or legal issues you may have encountered during your residence in the U.S.

Once the USCIS receives and reviews your Form N-400, you will first be scheduled for a biometrics appointment to complete security checks. Then you will be advised if additional information or evidence is required or invited to attend a naturalization interview, during which you will be asked

questions about your application and will also be required to take the required English and civics tests.

If your application for naturalization is approved, you will take the Oath of Allegiance and officially become a U.S. citizen.

Form N-400 Processing Time In 2023

N-400 processing time is 8-10 months, depending on the field office where you file your application for naturalization, as per the processing times on USCIS website.

The estimated processing time for the Form N-400 is based on the processing time of 80% of the cases received and processed during the prior six months.

Because each case is unique, these processing times should be treated only as a general reference.

Factors that can affect the N-400 processing time include:

  • USCIS workload: A high number of applications can lead to longer processing times.
  • The type of naturalization eligibility: Some categories, such as spouses of U.S. citizens, may have expedited processing compared to other categories.
  • Application accuracy: Incomplete or inaccurate applications can lead to delays.
  • Requests for additional information: USCIS may request additional information or documentation, which can extend processing times.
  • Background checks: USCIS background checks can take an extended amount of time if there are discrepancies between the applicant’s background and the information stated in the naturalization application.

If your case takes longer than the estimated time shown on the USCIS website, you can submit an inquiry about the status of your application.

Form N-400 Processing Stages

The N-400 timeline includes several major stages:

1. Receipt Notice

Once you file Form N-400, USCIS will acknowledge the receipt of your application by sending a receipt notice, Form I-797C, Notice of Action.

The receipt confirms that your application has been received, while the receipt number gives you the ability to track the progress of your application.

2. Biometrics Appointment

You will be scheduled for a biometrics appointment at a local Application Support Center (ASC), where your fingerprints, photograph and signature will be collected for a background check.

The biometrics appointment typically takes 30 minutes. You might be asked to bring additional documents to the appointment, including a state-issued photo identification card, a national photo identification from your home country or a driver’s license.

USCIS will collect your biometrics and conduct a background check, including criminal, security and immigration history checks. They will also review your N-400 application and supporting documents for accuracy.

3. Interview Notice

If the preliminary checks are approved, you will receive a notice for your naturalization interview, specifying the interview date, time and location.

4. Naturalization Interview & Tests

The naturalization interview takes approximately 30 minutes and includes questions about your background and eligibility.

At the interview, you will be asked to complete English and civics tests, which are meant to assess your ability to speak, read, write and understand English, along with your knowledge of U.S. government and history.

5. Decision On Application

Following your naturalization interview, USCIS will make a decision on your application.

If your application is approved, you will receive an approval notice.

If your application is missing information, USCIS may request additional information or schedule a follow-up interview.

If USCIS finds you ineligible for naturalization, your application will be denied.

6. Oath Of Allegiance

If your application is approved, you will receive a Notice of Naturalization Oath Ceremony, to schedule your naturalization ceremony.

At the ceremony, you will take the Oath of Allegiance to the U.S. and officially become a U.S. citizen.

As proof of your citizenship, you will receive a Certificate of Naturalization.

Challenges Of Form N-400

To navigate the naturalization process successfully, you should be aware of the potential challenges and risks you might encounter.

Challenges include:

  • Naturalization tests: If you fail the English and civics tests, your application for naturalization is likely to be denied.
  • Documentation: If you file incomplete or inaccurate supporting documents, this might lead to delays or a denial.
  • Criminal convictions: Certain criminal convictions can make you ineligible for naturalization or lead to removal from the U.S.
  • Continuous residence requirements: If you are unable to demonstrate that you have continuously resided in the U.S. for the required period, your application might be denied.
