Citizenship
Become a U.S. citizen.
Naturalization is the final step of the immigration journey. If you've been a permanent resident long enough and meet the requirements, Form N-400 is how you apply to become a U.S. citizen.
What naturalization is
Naturalization is the process by which a lawful permanent resident becomes a U.S. citizen. The application is Form N-400, Application for Naturalization.
Becoming a citizen brings the right to vote, a U.S. passport, protection from deportation, and the ability to petition for more family members, among other benefits.
The process includes a background check, an interview, and tests of English and U.S. civics, followed by the Oath of Allegiance. AOSvisa will help you prepare and file the N-400 accurately; how we support the interview and tests will be detailed as we build the service.
Who qualifies for naturalization
Eligibility rules vary, but most applicants must meet requirements like these:
- Be a lawful permanent resident for at least 5 years — or 3 years if you've been married to and living with the same U.S. citizen for that time.
- Be at least 18 years old at the time of filing.
- Meet the continuous residence and physical presence requirements in the United States.
- Demonstrate good moral character.
- Be able to read, write, and speak basic English and pass a U.S. civics test (with some exceptions by age and time as a resident).
- Be willing to take the Oath of Allegiance to the United States.

Citizenship questions
- How long do I have to be a permanent resident first?
- Generally 5 years, or 3 years if you've been married to and living with the same U.S. citizen for those 3 years. Other special rules exist, for example for some members of the military.
- Is there a test?
- Yes. Most applicants take an English test and a U.S. civics test at the naturalization interview. Some applicants qualify for exceptions or accommodations based on age, time as a resident, or disability.
- How long does naturalization take?
- Times vary by field office and case. We don't estimate USCIS processing times — check current times at uscis.gov.
- Does applying put my green card at risk?
- For most straightforward cases, no. But naturalization involves a full review of your record, so if you have issues like certain criminal history or long absences from the U.S., it's wise to consult an attorney before filing.
- Is AOSvisa a law firm?
- No. AOSvisa is self-help software and does not provide legal advice. For advice about your situation, consult a licensed immigration attorney.
