What is naturalization?
Naturalization is the legal process for a lawful permanent resident, also called a green card holder, to become a U.S. citizen. The application is filed on USCIS Form N-400. After USCIS approves the application, the applicant attends an interview, passes an English and a U.S. civics test, and takes the Oath of Allegiance. Once naturalized, the new citizen can vote, hold a U.S. passport, sponsor more family members, and is no longer at risk of deportation for most reasons.
Who qualifies?
- Age 18 or older at the time of filing
- Lawful permanent resident for at least 5 years, or 3 years if married to and living with a U.S. citizen spouse
- Continuous residence in the United States during that period
- Physical presence in the United States for at least half of the qualifying period
- Lived in the state or USCIS district of filing for at least 3 months
- Good moral character during the statutory period
- Basic ability to read, write, and speak English, with limited age and disability exceptions
- Knowledge of U.S. history and government, tested as the civics exam
- Willingness to take the Oath of Allegiance
How the process works
- Confirm eligibility. Review permanent-residence history, travel records, tax filings, criminal history, and selective-service registration to confirm you qualify.
- File Form N-400. Submit Form N-400 with USCIS together with required documents and the filing fee.
- Biometrics appointment. Attend a fingerprint appointment at a USCIS Application Support Center.
- Interview, English, and civics tests. Attend an interview with a USCIS officer who reviews the application, asks questions in English, and administers a reading test, a writing test, and a civics test of up to ten questions.
- Oath of Allegiance. If approved, attend a naturalization ceremony and take the Oath of Allegiance. You are a U.S. citizen from that moment forward.
Timeline and what to expect
A naturalization case generally takes 8 to 14 months from filing to oath, depending on the field office that processes the application. Some applicants in Massachusetts see faster processing through the Boston field office; others wait longer when interview slots are limited.

How Chaudhry Law helps
The firm screens carefully for trip-based residence problems and good-moral-character risks before filing, so problems are surfaced and addressed up front rather than at the interview. We track your travel and continuous-residence math, gather the supporting documents the officer will ask for, and walk you through realistic interview practice including the civics questions. If a risk exists, we tell you, and we make the call together about whether and when to file.
Frequently asked questions
Can I apply if I have been outside the U.S. for long trips?
Trips of six months or more raise a rebuttable presumption that you broke continuous residence. Trips of one year or more break it outright, with limited preservation-of-residence exceptions. Talk to the firm before filing if you have been away for any extended period.
Do I have to give up my original citizenship?
Not under U.S. law. The United States allows dual citizenship. Your country of origin may have its own rules, so confirm with that country's consulate.
Will an old arrest stop my naturalization?
It depends. Even arrests that did not lead to conviction must be disclosed and may need explanation. Sealed and expunged records still count for immigration purposes.
What if I cannot speak English well?
Limited exceptions apply for older applicants who have been permanent residents for long periods. Most applicants must demonstrate basic English ability. The firm helps prepare for the test.
Can I sponsor relatives once I naturalize?
Yes. As a U.S. citizen you can petition for spouses, children, parents, and siblings, generally with shorter wait times than as a permanent resident.
