The N-400 allows lawful permanent residents to apply to become a U.S. citizen. The N-400 does not guarantee that you will become a citizen. It is the official document that will let you naturalize if you meet all the requirements.
How to File for Citizenship with the N-400
Fill out USCIS form N-400 and gather documents that will help prove to USCIS that you have “good moral character.” Materials that help show your good moral character can include criminal records, tax records, receipts on regular payments such as rent, car, insurance, and more.
The USCIS will want to prove that you will contribute to society in a positive manner. By providing them with examples of your reliability on tax and child support payments as well as community service, you will help improve your case for naturalization.
Required Documents for N-400
- School and/or job info for the last 5 years
- Address info for the last 5 years
- Contact info for your children (if relevant)
- Contact info for former/current spouses
If you live in San Antonio (or Texas in general), you must submit the N-400, naturalization fees, and all required documents to:
P.O. Box 660060
Dallas, TX 75266
For Express Mail or Courier Deliveries
2501 S State Hwy 121 Business
Lewisville, TX 75067
After Submitting the N-400
Processing an N-400 can take up to 6 months. After submitted, you will receive a Notice of Action (Form I-797) that confirms receipt.
If you want to check the status of your USCIS case, submit your receipt number from the Notice of Action to the USCIS Status Online site.
After you file your application for naturalization, USCIS will send you a notice that will require your biometrics to be taken.
When you arrive for your biometrics, you will need to bring:
- Green card
- Second form of ID
- Notice letter for biometrics
You will also be subject to an interview by the USCIS. The interview will test your skills on reading, writing, and speaking English proficiently.
The interview will also have a Citizenship Test. The test will have 10 questions relating to the rights and duties of U.S. citizenship (also known as U.S. Civics).
Don’t worry if you fail the Citizenship Test. Any applicant who fails the test can retest up to 90 days later.
If you cannot take any part of the naturalization test due to a mental or physical impairment, file USCIS Form N-648. This allows an exception and allows aid during your naturalization process.
N-400 Naturalization Requirements
If you want to become a citizen, you must prove that you have done the following for naturalization:

- Reside in the U.S. for 5 years

N-400 Frequently Asked Questions
Do I need to renew my green card if I file for the N-400?
No. You can file for the Citizenship Application with an expired green card.
Can I still file a citizenship application even if I was convicted of a crime?
Yes. Be honest and upfront about your criminal history with USCIS and submit any documentation that will prove you have become a person of good moral character (written statements from officials related to your case, rehabilitation documents, along with standard documents proving moral character).
What happens if I move after filing?
What if my N-400 is denied?
You can appeal. Within 30 days of receiving your denial, file Form N-336, which will request a hearing for your naturalization.
If the appeal upholds the denial, you can file another review with a U.S. District Court.
Why would my Application for Naturalization get denied?
USCIS has many reasons why an application may be denied. While the decisions for approval are ultimately their own, here are some reasons why your application might have been rejected.
Accidentally faulty information was provided. Sometimes, people guess on answers in their citizenship application. If you are not sure about an answer on the application, consult an immigration attorney or other resource before answering. USCIS will check every single fact, so it is critical to be accurate.
Didn’t read the instructions. USCIS wants you to succeed. That’s why they offer comprehensive instructions that guide you through the citizenship application process.
Didn’t supply all needed documents. Be comprehensive when supplying USCIS with all needed documents.
Didn’t register with Selective Service. All men between ages 18 and 26 must register for Selective Service. If this applies to you, click on this link to register for Selective Service.
