Form N-400 Guide (Application for Naturalization): Everything You Need to Know

Many immigrants who move to America do so to one day become U.S. citizens. While there are many paths to gaining U.S. citizenship, the process can be difficult. To start, some people confuse having a permanent resident card (being a green card holder) with being a U.S. citizen.

Even when the applicants understand what U.S. citizenship is, the processing delays can also be quite frustrating. Usually, the best way to become a U.S. citizen if you already hold a permanent resident card is to file form N-400 to the United States Citizenship and Immigration Services (USCIS).

When filed correctly, the N-400 application for naturalization form will give you the best chance of obtaining your citizenship in just under a year.

However, if you have ever submitted similar applications to government institutions, you will know that they can be complicated. This is why you need guidance, and Citizen Concierge is here to help.

With help from highly experienced and qualified Citizen Concierge agents, the Form N-400 instructions will no longer seem daunting, and you can confidently apply for U.S. citizenship at your nearest USCIS field office.

What is Form N-400?

Before getting into a detailed explanation of the N-400 form, you need to understand what naturalization is. If you are already a green card holder, naturalization is the process through which you can voluntarily become a U.S. citizen. This is the most common way for anyone born outside the U.S. to become an American citizen.

To do this, you will usually need to file Form N-400, along with a bunch of accompanying documents to prove your eligibility for the naturalization application process. The criteria for qualification are very strict, so before you start the process and pay any application filing fee, you need to confirm that you meet the eligibility requirements.

Also, the Form N-400 application is handled by the U.S. Citizenship and Immigration Services (USCIS), a member of the U.S. Department of Homeland Security (DHS). This means this is the only official body that is allowed to offer you a green card or American citizenship.

What Is the Filing Fee?

When you apply for U.S. citizenship through the USCIS field office, you will be expected to pay a filing fee, which is divided into two parts. First, you will pay $640 for the processing of your naturalization application forms and then $85 for the biometric fee.

In total, you should expect to pay $725 for the entire process, and this application fee payment is non-refundable. This means you will lose your money even if your application for naturalization is unsuccessful. As such, you need to make sure you follow the instructions carefully and that you meet the criteria to become a U.S. citizen.

How Long Does the Naturalization Process Take?

It is not easy to say with certainty how long your Form N-400 application for naturalization will take. There are a number of factors that will determine the length of time you will have to wait, such as the workload at the USCIS field office.

Generally, barring any processing delays, you can expect the entire process to take about 8-12 months. However, there are steps you can take to ensure expedited processing, such as taking advantage of the early filing date.

If you are in a race against time, you can contact Citizen Concierge and find out what steps you can take to try and get your application for naturalization to go quicker.

Can Applicants Expedite Their Form N-400?

Yes, as mentioned above, applicants can expedite the application for the naturalization process when they file Form N-400. Filing early is generally the best way to do so. The USCIS has implemented a 90-day early filing rule, which many shrewd applicants are taking advantage of.

Usually, a green card holder has to wait for three or five years, depending on their permanent resident card status, before they can apply for U.S. citizenship.

Under the 90-day early filing rule, you can apply for citizenship three months before the end of your wait period. However, in most cases, the continuous residence requirement will apply, meaning you must have stayed in the U.S. continuously over the entire waiting period.

If you want to know your normal filing date, simply check the date on your green card and add either three or five years, whichever is applicable. To get your early filing date, you will then subtract 90 days from your normal filing date.

The USCIS makes determining your early filing date a lot easier by providing an easy-to-use online calculator on its official website. You can also contact a Citizen Concierge filling specialist for assistance.

Eligibility Requirements for U.S. Citizenship

Considering the amount of money you will have to pay for the non-refundable filing fee, the time spent filling in and submitting the N-400 form, and the waiting period while the application is being processed, it is vital that you make sure that all the eligibility requirements for application for naturalization are met.

Who Can File Form N-400?

The most important requirement is that you must be at least 18 years old at the time of filing and have been a green card holder for at least three or five years before you file Form N-400. Once these basic conditions are met, you must determine whether you fall into any of the following categories:

  • You have held a permanent resident card for at least five years.
  • You are married to a U.S. citizen and have been married and living together with that same U.S. citizen for the last three years.
  • You are a member of the military service (or honourably discharged from the military or naval service in the last six months) and have been part of the military service for at least one year.

While most applicants usually fall into one of the categories above, there are some exceptions to these rules that the USCIS may be willing to consider. To be sure, visit Citizen Concierge and check your eligibility.

Who Cannot File Form N-400?

There are certain applicants who will automatically be excluded from filing Form N-400, including the following:

  • Applicants who do not meet the eligibility requirements stated above
  • Applicants who derived or acquired U.S. citizenship through being a child of a U.S. citizen and living abroad or having at least one of their parents being a U.S. citizen

The eligibility requirements can get confusing at times. If you find that you do not qualify for a Form N-400 application or that you need to request expedited processing, you can seek assistance from qualified filing specialists.

Required Documents

One of the things you have to be very careful about is ensuring that you submit all the required supporting documents along with your Form N-400 application.

If you are sending your Form N-400 application electronically, you will have to upload each document and send it together with the application form.

Understandably, you may not have all the required documents on hand when you begin the application process, but you can continue while you gather everything that is required. It takes a long time to get your application to become a U.S. citizen approved, so there is no time to stop the process while you look for the required documents.

The following are the required documents that ALL applicants need to have:

  • A clear copy of both sides of the permanent resident card, which is also called the green card
  • Proof of payment of the filing fee

In some cases, additional information and supporting documents may be required depending on the criteria for eligibility. Some applicants may be required to provide the following:

  • The “Medical Certification for Disability Exceptions”, officially called Form N-648, when applying for the exemption from the U.S. citizenship tests based on a valid medical condition that makes taking the test impossible
  • A “Request for Certification of Military or Naval Service,” which is required as proof of qualifying military service of at least one year or honourable discharge in the last six months
  • 2 square-inch passport-style photos for all applicants who are applying for citizenship from outside the U.S.
  • Proof of your current marital status, whether still married to a U.S. citizen or divorced, in the form of a marriage certificate, annulment certificate, divorce papers, or death certificate if the spouse passed away

English translation certificates may be required in cases where any of the required documents are in a foreign language. If you head over to Citizen Concierge, you will find the full list of requirements and Form N-400 instructions that you need to follow.

N-400 Online Filing

Thanks to modern technology, you can now submit both Form N-400 and the filing fee online, which is a much faster and easier method. However, simply because you have chosen to submit your Form N-400 online does not mean that the processing time will be faster.

One thing all applicants need to remember is that the USCIS is not there to help them fill out Form N-400 correctly. All they want to do is process the application, and any errors that you make will damage your chances. This is the main disadvantage of quickly submitting your form online.

However, if you make sure that all the requirements are met and that all supporting documents have been uploaded correctly, applying for citizenship using an online Form N-400 application is a good option to consider.

Whether you are applying online or by physically sending your completed Form N-400 to the USCIS field office, you will need to get the form from the USCIS website. New editions of these forms are occasionally published, so make sure you are filing the most current version of Form N-400.

If you choose to apply online, you will need to start by creating an online account on the USCIS website. This will be where you will fill out your Form N-400 and upload all the supporting documents. You will also be able to sign your name electronically by typing it at the end of the document.

However, not all applicants are allowed to file Form N-400 online. If you are applying for a fee reduction or waiver, or you are sending your application from outside the country, you will have to file your application physically by sending your Form N-400 to the USCIS mailing address.

Where to Send the N-400 Application for Naturalization Form

The place where you send your Form N-400 is different for online applicants and those who apply using a physical form. One thing you are not allowed to do is to submit your forms in person, even if you live very close to the United States Citizenship and Immigration Services offices.

TIn general, if you send your Form N-400 via a mailing address, it will be to the USCIS field office in your state. You will also need to decide on the type of delivery service you want, such as DHL, UPS, or FedEx.

However, if your eligibility criteria are based on your military service record or the military service of your family member, you will have to send your Form N-400 application to a special address that the USCIS will tell you.

When the time comes that you need to go for an interview, you will likely be called to the USCIS field office that is closest to the physical address you provided.

General Guidance Before Filing

Before you file your Form N-400 and supporting documents to become a U.S. citizen, it helps to take some time to think carefully about how you will fill out the form, the information you will provide, and the method you will choose to send the application to the USCIS.

To avoid making costly errors when submitting Form N-400, remember the following:

  • Unless you are specifically asked to provide original documents, such as your permanent resident card or marriage certificate, you should always use a photocopy.
  • You must submit your Form N-400 with the most recent filing fee, which you can pay using a money order, personal check, cashier’s check, or credit card (using Form G-1450).
  • You may need to provide translations for all foreign language documents, and the translation must be certified.
  • N/A is used to answer all non-applicable questions, while none is used when the answer is zero.
  • You must use black ink to fill in the entire Form N-400 application.

How to Fill Out Form N-400: Important Instructions

When you have determined your eligibility and gathered the required documents, you need to start filling out your Form N-400. Instructions on how to do it are as follows:

Section 1

The first part of the form concerns your eligibility to apply using Form N-400 for U.S. citizenship. Here, you must indicate under which criteria you can apply.

Sections 2, 3, and 4

Parts two to four deal with your personal information, any accommodations you may require, and how the USCIS can contact you to provide details regarding the status of your application.

You will need to provide your full legal name along with any other versions of your name that may be applicable. This must be the same name on your permanent resident card or any other supporting documents you will include.

If you include your marriage certificate, you can use it as a legal name change document, and your married name will be used by the USCIS if you are awarded a certificate of naturalization.

You will also need to indicate any special accommodations that you require, such as impairment or disability exceptions that exclude you from taking the biometric screening or sitting for the citizenship test. If you have lived in the U.S. for many years, you may be eligible for exclusion from the English portion of the test.

In the fourth section, you will have to provide the USCIS with your contact details so that they can inform you of the outcome of your application. It is unusual for the USCIS to call applicants, so make sure you include an email address that will be used for correspondence.

Sections 5, 6, and 7

The USCIS can also decide to mail you instructions, notices, and appointments, so in this section, you will need to include your residential or mailing address. Also, be sure to include your address history going back as far as the last three or five years, according to your eligibility criteria.

If you have at least one U.S. citizen parent, you will need to provide information about them, such as names and contact information. Otherwise, you can skip this section by answering with “N/A.”

Section seven is reserved for your biographic information, which has to do with your race and ethnicity, as well as other details about your physical appearance, such as hair colour, eye colour, weight, and height.

Sections 8 and 9

In the eighth section, you will need to list all your employment information for the past five years, which includes the places you have worked at, schools you have attended, as well as any information about military service and self-employment.

If there is too much information to fit in the space provided, you can attach an addendum with all the additional employment details.

If you have travelled outside the U.S. during your five-year wait period, you will need to list all the places you visited, as well as the dates and duration of each trip. This includes any visits to the Caribbean, Canada, or Mexico.

This will help to determine whether you meet the continuous residence requirement for Form N-400 applications. In most cases, trips that last over six months will disrupt these continuous residence requirements.

Sections 10 and 11

You will need to provide information about your marital status and marital history. If you are applying based on being married to a U.S. citizen currently or in the past, you will need to be as accurate as possible when submitting your information.
Also, you will need to supply information about all of your children, such as names, ages, and locations.

Section 12

Under section 12 of your Form N-400 application, you will be asked to include additional information about yourself. There is a good moral character requirement for each application, which is greatly affected by your answers in this section, so you need to be careful when answering.

In cases where you are unsure whether your involvement with a certain individual, group, or organization may affect your chances of being granted citizenship, you should consider talking to an immigration lawyer.

Sections 13, 14, and 15

Section 13 of Form N-400 is about the applicant’s statement. Do not forget to sign this section because many rejections are because of this small error.

If another person has interpreted or prepared Form N-400 for you, they must submit their details under sections 14 and 15. Also, they should sign as the interpreter or preparer.

Sections 16, 17, and 18

The last three sections of your Form N-400 should be left blank. Do not fill in any information under sections 16, 17, and 18. These areas will be filled in after your interview and during the oath ceremony.

N-400 Filing Tips: The Do’s and Don’ts

The way you fill in your Form N-400 is vital to the success or rejection of your application for U.S. citizenship. As such, you need to be very careful that you do not submit a form full of errors or wrong information.

To make it easier for you, remember the following do’s and don’ts for every lawful permanent resident applying for citizenship using Form N-400:


  • Provide translations for all supporting documents that are written in a foreign language
  • Review your Form N-400 thoroughly before submitting it to make sure there are no blank spaces, false information, or factual errors
  • Make sure you sign whenever you are required to do so
  • Always use black ink to type or print the Form N-400


  • Do not submit any unnecessary paperwork along with your application form, as this will not improve your chances of being approved
  • Do not use original documents as proof of supporting documents in your application
  • Do not cross out, highlight, type beyond the provided spaces, or otherwise clutter your application form

Application Review and Interview Process

After you submit Form N-400, the USCIS will review it and ask you for additional information or documents if required. You will then be asked to come in for your biometric scans, which will be used to verify your identity as well as run background and criminal history checks.

Once you are cleared of any past criminal activity, you will be invited to come to your nearest USCIS field office for an interview.

You can prepare for the naturalization interview by going over all your answers in the Form N-400 application, brushing up on your English, studying for the civics tests, and gathering any additional documents you may have been asked to bring.
