Gather Required Documentation for Your Application

Are you needing to gather documents for your citizenship application? To better prepare yourself for the citizenship application and interview, we have listed out the documents that you will need to gather for your application for citizenship in advance of your interview with USCIS for naturalization.

  1. Form N-400: The Application for Naturalization.
  2. Proof of Permanent Residency: You must provide proof of your permanent resident status. This would be your current green card(s) in the form of Form I-551, and any that have expired while you have applied to renew them or upgrade them to a 10-year green card and can provide proof of such application.
  3. Marriage Certificate: Copy of the marriage certificate to prove marriage.
  4. Spouse's Citizenship Evidence: Evidence of spouse's U.S. citizenship. For example, spouse's birth certificate or spouse's naturalization certificate.
  5. Proof of Residence: You and your spouse must provide proof that you both have lived together for the period of time required by law in order to apply for citizenship. For example: joint bank statements; a lease or rental agreement showing both of your names; and copies of your joint tax returns.
  6. Photographs: Two identical color photographs copied to black and white that meet USCIS specified criteria. The photographs must have been taken within the last six months.
  7. Processing Fee: Currently this covers the cost of processing the application for citizenship plus the cost for the biometrics for the application. This currently costs $760.00 for the application plus $70.00 for the biometrics services for a total of $830.00.

As you prepare for citizenship, gather required documents to support your citizenship application and help your preparedness and awareness of what documents you need for the application process. Be sure to gather supporting documents to establish that you and your spouse have lived together at the same residence for the time required by law to establish eligibility to apply for naturalization. Keep good records to provide evidence of your current residence as well as your past residence. Gather documents listed for application Form N-400 early in order to alleviate anxiety that may develop as you await your naturalization interview with USCIS. In addition to making application for citizenship less stressful, preparing early for your citizenship application helps you to focus on your goals for your future in this country and get ready to achieve your American dream.

Submit Your Citizenship Application: Step-by-Step Process

This is a step by step guide that will help applicants for citizenship to complete the submission process for their citizenship application.

  1. Fill out Form N-400: Start your application for citizenship by filling out Form N-400 (Application for Naturalization) in black ink and sign it in all the appropriate places.
  2. Prepare All Documents Required to Prove Your Eligibility for Citizenship: You need to provide evidence of your citizenship status as well as proof of your residence in the US and identification.
  3. Pay appropriate processing fee: As of 2/14/23, the processing fee for Form N-400 for Naturalization will be $760 for paper filings and $710 for filings submitted online using the USCIS Online File System. Applicants may qualify for a reduced fee of $360 if they are statutorily eligible or for a free application if they are eligible for a free application under USCIS’s Custody of refugees or asylees with approved I-730 petition, respectively.
  4. Send Your Application: Your application can be submitted online, or sent by regular mail to the USCIS Service Center for your state.
  5. Get a Receipt: Within a few days after you have submitted your application you will receive a receipt notice in the form of a pink slip (Form I-797C). The receipt notice will inform you whether the USCIS service center accepted your application or if it was returned to you for specific reasons. Make sure to keep the receipt with your other documents.
  6. Go to your Biometrics Appointment: When USCIS has accepted your citizenship application you will receive an appointment for your Biometrics which will include: a photograph of your face, the fingerprints of both hands and your signature. These items are all collected for identification purposes only.
  7. Track your submission: You can track the status of your application by logging into USCIS ONLINE (USCISONLINE.md.uscis.gov). You will be advised of any action required by you.

We all know that naturalization is a long and arduous process. Remember that every step of the way you are one step closer to your goal of becoming a citizen. Please note, however, that applicants who file for citizenship after October 20, 2025 will be required to take the new 2025 civics test.

Each box represents a step you need to take to apply for citizenship. Follow the arrows to see how each step connects to the next, guiding you through the entire application process.

The process of citizenship for naturalization can be complex and confusing. There are many situations and circumstances faced by citizenship applicants in their struggles with their citizenship applications, many of which occur frequently with other applicants as well.

  1. Incomplete Applications: It is imperative that all sections of Form N-400 are completed. Some sections of the form may seem to be irrelevant to citizenship. In fact, if the sections are completed properly, 91% of individuals test successfully on their first try for citizenship.
  2. Insufficient Evidence of Marriage: Furthermore, USCIS requires that the marriage of an applicant for citizenship be genuine and currently thriving. Thus, to satisfy the requirements for proof of shared finances, an applicant can gather joint bank account statements and other documentation which reveals shared expenditures for household items and personal effects. Evidence of shared activities and joint life outside of work may also be sufficient to establish a marriage that is currently thriving. Such documentation might include photos of the applicant and his/her family and friends as well as written documentation of travel taken together as well as other shared activities and events.
  3. Inconsistent Information: The information contained in the application for citizenship as well as the documents that are used to support it must contain consistent information throughout. Material discrepancies in information could lead to USCIS giving your application any additional scrutiny including requesting additional documentation and possibly even denying your application for citizenship.
  4. Failure to Respond to Requests: USCIS applicants and their families must make every effort to timely respond to all requests for additional documentation from USCIS officers. There are currently 100-200 cases per month referred by USCIS officers to the Department of Justice for potential denaturalization and most of these involve recently naturalized U.S. citizens who became U.S. citizens after January 2021.
  5. Interview Preparation: Review some typical citizenship interview questions. Practice your answers to U.S. history and government questions. A new pool of 128 civics questions was introduced on October 20, 2025. Applicants will be tested on 12 of the 20 questions.

Anticipating the problems that occur with applications for citizenship allows you to be better prepared to face the inevitable obstacles along the path to citizenship and to start living in the U.S. as soon as possible.
