At a Glance: Form N-400 is an application issued by the United States Citizenship and Immigration Services (USCIS) for individuals seeking naturalization. It consists of 18 sections that require detailed information about the applicant’s eligibility, personal details, residence, parents, biographic information, employment and education history, time spent outside the US, marital and parental status, additional information, and declarations.

The form concludes with signatures and sections to be completed during the citizenship interview.

The United States of America sees many people trying to immigrate there permanently for various reasons, such as better standard of living, employment opportunities, or living with family. If you are one of those people, you would have to go through naturalization to complete your migration. This process includes filling the form N–400. It is mandatory to fill this form, so here is the instruction on how to fill out each section of this form.

What Is Form N–400?

The United States Citizenship and Immigration Services give out a form called N–400 to whoever wishes to become a natural citizen. This is not a single–page application. Instead, it is over 20 pages long and has 18 separate sections asking the applicant for many details about their lives to determine if their application should be accepted.

N–400 Instructions

The N-400 form has 18 separate sections that require your answers. However, you are not required to answer every question. Unnecessary answers must be avoided, and you should only answer questions that are applicable in your situation and simply write NA on all remaining questions.

Never try to make up an answer. It is recommended to always answer each question truthfully since lying on your immigration application can lead to severe consequences. Check out the N-400 timeline guide here.

The following are instructions on 18 parts of the application form.

Part 1: Information About Your Eligibility

In this section, only one question asks you to select your eligibility criteria from the options provided. Read them all, decide which category best fits you, and select only that one. Do not select multiple options for this question.

Part 2: Information About You

This section has questions asking your basic information, such as your name, address, social security number, and other information. One question also asks if you have any disability or physical impairment that does not permit you from attempting your English and civics test that would be compulsory otherwise.

Part 3: Accommodations for Individuals with Disabilities and Impairments

In this section, if you do have a disability, you can request the USCIS to provide some form of accommodations for your naturalization tests, such as asking for a wheelchair in the building, a sign language interpreter, or any other accommodation that you might need to give your test with ease.

Part 4: Information to Contact You

In this section, you will give your contact information, such as your phone number and email address, for contacting you from the USCIS office.

Part 5: Information About Your Residence

Here, you will give all the addresses you have lived at for the past five years, including your current address. If the given space is not enough, simply write “see the attachment” and attach a white paper with your name, A – number, and a heading that states, “Attachment to form N–400,” and write the question number and section number to fill out the details of those questions for which, the space in your original form wasn’t enough.

Part 6: Information About Your Parents

Here, you need to provide information about your parents, particularly their nationality. If both or even one of your parents are US Citizens, you might not have to fill out your N–400 forms since you would already be a US Citizen.

Part 7: Biographic Information

For biographic information, you need to give your race, ethnicity, height, weight, markers such as moles or tattoos, eye color, and hair color so that USCIS can complete your background verification.

Part 8: Information About Your Employment and Schools You Attended

This part will talk about your employment status and education in the last five years. You should also mention if you have had any periods of unemployment, disability staying home to take care of a family, and the schools you have attended in the last five years. It’s okay if you can’t remember everything with pinpoint accuracy, but try to fill in as much information as possible.

Part 9: Time Outside the United States

Now, you need to disclose the number of days you spent outside the US in the last five years on an annual basis. This is to determine if you have met the requirements to stay in the country physically. You need to remain in the US for a fixed number of days every year.

Part 10: Information About Your Marital History

You should disclose information about your current spouse and give information regarding the same. Always include information about your current marriage along with any previous marriages you or your current spouse have had.

For example, one question asks how many marriages has your spouse had? And if you’re their 3^rd spouse, you answer 3 to include your marriage and not 2.

Part 11: Information About Your Children

Provide all, and every bit of information asked regarding your children, such as missing or deceased, married or unmarried, living with you or not, stepchildren not yet adopted legally, and those born out of wedlock.

Part 12: Additional Information About You

You will need to give additional information that will be used to gauge if you should be accepted. Answering “No” to any of the questions in this section could result in your application being denied. If that is the case, finding an immigration lawyer would be best.

Part 13: Applicant’s Statement, Certification, and Signature

Here, you declare that you have clearly understood everything about N–400 form and sign it.

Part 14: Interpreter’s Contact Information, Certification, and Signature

In case you used an interpreter to help you with your application, the details and contact information about the interpreter should be mentioned here, along with both your and your interpreter’s signatures.

Part 15: Contact Information, Declaration, and Signature of the Person Preparing This Application, if Other Than the Applicant

if you used someone else to prepare your application for you, such as a lawyer, paralegal, or anyone else, then they need to sign this place. If not, you can just leave “NA” here and move on.

Part 16: Signature at the Interview

Leave this part blank. This is where you sign after your citizenship interview is completed.

Part 17: Renunciation of Foreign Titles

If you have any foreign titles such as prince, duke, etc., you need to renounce them here in this section to attain citizenship.

Part 18: Oath of Allegiance

Leave this section blank as well. It needs to be filed during your citizenship interview.
