Frequently Asked Questions
What documents do I need to submit with my naturalization petition?
Required documents include your green card, birth certificate, passport, marriage certificate (if applicable), proof of U.S. residence, and tax returns for the past 5 years. A complete list is provided with Form N-400. You may also need additional documents depending on your specific circumstances.
What is the English requirement for naturalization?
Applicants must demonstrate a basic ability to read, write, and speak English. The USCIS tests these skills during your interview. You can study civics and English together using free resources on the USCIS website. Exceptions exist for applicants over 50 or 65 who have been permanent residents for specific periods.
What topics are covered in the civics test?
The civics test covers U.S. history and government, including topics like the Constitution, branches of government, rights and responsibilities, and historical events. You will be asked up to 10 questions from a publicly available list of 100 questions. You must answer at least 6 correctly to pass.
What happens after I pass the naturalization test and interview?
After passing the test and interview, you will be scheduled for an oath ceremony. At this ceremony, you will take the Oath of Allegiance to the United States and receive your Certificate of Naturalization. This document officially establishes you as a U.S. citizen.
How long does the naturalization process take?
Most applications are processed within 6-12 months, but processing times vary by location and current USCIS workload. You can check your application status online using your receipt number. Some applications may take longer if additional background checks are required.
