What Are Immigration Naturalization Services?

Immigration naturalization services cover legal help with becoming a U.S. citizen — grounded in immigration and naturalization law reviewing eligibility, preparing and filing Form N-400, prepping for the civics and English tests, and representing you if issues come up.

A naturalization attorney catches the things that cause delays before the application ever reaches a USCIS officer. For the full range of services, visit the immigration services overview.

Who Qualifies for Naturalization?

Most applicants qualify under the five-year path as a lawful permanent resident, or the three-year path as the spouse of a U.S. citizen. USCIS also reviews continuous residence, physical presence (30 months minimum), good moral character, English and civics requirements, and attachment to the Constitution.

You must be at least 18 and have lived in your USCIS district for at least three months.

The Civics Test: What’s Changed

Anyone who filed Form N-400 on or after October 20, 2025 takes the 2025 civics test — not the 2008 version. USCIS draws 20 oral questions from a bank of 128; you need 12 correct to pass. Answer 9 wrong and the test stops. One retake is available 60–90 days later. Age-based exemptions apply at 65+ with 20 years of residency.

The Naturalization Process: Step by Step

The sequence: eligibility review → N-400 preparation → filing and biometrics → interview and testing → decision → oath ceremony.
Timeline runs several months to over a year. You can file up to 90 days before your five- or three-year mark — not a day earlier.

MVD When You

When You Need a Naturalization Attorney

Not every case needs legal help. But a naturalization attorney matters when you have a criminal history, extended travel abroad, tax issues, prior immigration violations, or a denial to appeal. Naturalization is permanent U.S. citizenship. It’s worth doing right.

Frequently Asked Questions

Eligibility and Residency Requirements

How long do I have to hold a green card before I can apply?
Most people asking about immigration naturalization services are in this situation: they’ve had a green card for years and want to know when they can file. The answer is five years for most applicants, or three years if you got your green card through marriage to a U.S. citizen and you’re still married and living together. You can file up to 90 days before your anniversary date -” but not a day earlier than that window.
Can long trips outside the U.S. affect my eligibility?
Yes, and more than people expect. A single trip of six months or more raises a presumption that your continuous residence was broken. A trip of one year or more almost certainly breaks it. USCIS looks at the full five-year history, not just your most recent travel. If you’ve had extended absences, get a review before filing.
I was outside the U.S. for work. Does that still count against me?
It depends. Certain absences -” including work for U.S. government agencies or qualifying U.S. employers abroad -” may be preserved through Form N-470. But you’d need to have filed that form before the absence exceeded a year. This is a situation where legal guidance before you travel makes a big difference.
My green card says "conditional resident." Can I still apply for naturalization?
You can apply once you’ve removed the conditions and have a permanent green card. Conditional residents on a two-year green card generally need to file Form I-751 (or I-829 for investors) before the naturalization clock truly starts. Check your card carefully -” it matters.
Does my military service count toward the residency requirement?
Yes. Service members and certain veterans have special provisions under the Immigration and Nationality Act. Honorable service members may be eligible for naturalization on an expedited basis without meeting the standard continuous residence requirement. Speak with an attorney about what applies to your specific record.

The N-400 Application

What does Form N-400 ask about?
The N-400 is detailed. It covers five years of address history, employment history, marital history, travel outside the U.S., family information, and an extensive set of background questions about criminal history, tax compliance, membership in organizations, and your beliefs. It’s not a form to rush or fill out casually. That’s a big part of what immigration naturalization services from an attorney cover -” making sure nothing’s missed.
What happens if I make a mistake on my N-400?
Unintentional errors happen. The bigger issue is anything that looks inconsistent -” between your application and your actual record, or between what you wrote and what you say at the interview. USCIS has access to extensive records. Discrepancies get noticed. If you’ve already filed and realize there’s an issue, address it proactively.
Can I change my name through the naturalization process?
Yes. You can request a legal name change as part of your citizenship application, and it’ll appear on your Certificate of Naturalization. This is actually one of the most straightforward ways to legally change your name -” it doesn’t require a separate court proceeding in most cases.
How much does it cost to file Form N-400?
USCIS filing fees change periodically -” check the current fee schedule directly on USCIS.gov before filing. Fee waivers and reduced fees are available for qualifying low-income applicants. If you’re working with an attorney, factor in legal fees on top of the filing fee.
How long does the naturalization process take after filing?
Processing times vary by field office and fluctuate with USCIS workloads. USCIS publishes estimated processing times by office on its website. In practical terms, applicants should plan for a process that can run anywhere from several months to well over a year from filing to the oath ceremony.
