Naturalization

Overview

Naturalization is the process by which a lawful permanent resident — a green card holder — becomes a United States citizen. The application is filed on Form N-400 with U.S. Citizenship and Immigration Services (USCIS), and it ends, if all goes well, with the Oath of Allegiance and a Certificate of Naturalization.

Citizenship carries benefits a green card cannot match: the right to vote in federal elections, a U.S. passport, eligibility for federal jobs and benefits reserved for citizens, and the ability to petition for a wider range of family members on faster timelines. Just as important, a citizen cannot be placed in removal proceedings the way a permanent resident can.

Filing the N-400 also invites USCIS to review your entire immigration history. For most applicants that review is routine. For applicants with arrests, long trips abroad, or tax issues, it deserves careful attention before anything is filed. We evaluate the risks first, then file when the case is ready.

Who Qualifies

Most applicants qualify under the general five-year rule, but every requirement below must be met as of filing and maintained through the oath:

• Permanent residence: at least 5 years as a green card holder, or 3 years if you are married to and living with a U.S. citizen spouse for that period.
• Continuous residence and physical presence: you must have resided continuously in the U.S. for the qualifying period and been physically present for at least half of it. Trips of six months or more can break continuity.
• State residency: at least 3 months living in the state or USCIS district where you file.
• Good moral character: generally measured over the 5- or 3-year period, though USCIS may look further back. Criminal history, unpaid taxes, and false statements all matter.
• English and civics: ability to read, write, and speak basic English and pass a U.S. civics test. Exceptions exist: age 50 with 20 years as a resident or age 55 with 15 years may test in their own language; age 65 with 20 years receives a simplified civics test; applicants with a qualifying disability may seek a waiver on Form N-648.
• Attachment to the Constitution: willingness to take the Oath of Allegiance and support the principles of the U.S. Constitution.

Process Steps

1. Eligibility review

   Before anything is filed, we review your travel history, tax filings, and any criminal record — even old or expunged matters. Filing the N-400 opens your whole file to USCIS, so problems must be found and addressed first.

2. File Form N-400

   We prepare and file the application with supporting evidence: your green card, travel dates, marriage and tax records where relevant, and any documents explaining past issues.

3. Biometrics

   USCIS schedules a short appointment to take fingerprints and a photograph for background checks. Many applicants now have earlier biometrics reused instead.

4. Interview and tests

   An officer reviews your application under oath and administers the English test and the civics test. We prepare you for both and can attend the interview with you.

5. Decision

   USCIS grants, continues, or denies the application. A continued case usually means more evidence or a retest; a denial can be appealed on Form N-336.

6. Oath ceremony

   You take the Oath of Allegiance at a naturalization ceremony and receive your Certificate of Naturalization — the moment you become a U.S. citizen and can apply for a passport.

Timeline

Naturalization timelines depend on the workload of the USCIS field office handling your case. The ranges below reflect what applicants commonly experience:

Stage	Typical time
Case preparation and N-400 filing	2–6 weeks
Receipt notice and biometrics	3–8 weeks after filing
Wait for interview	4–12 months
Interview to decision	Same day to 120 days
Decision to oath ceremony	Days to a few months

Processing times vary by field office and change frequently. These figures are estimates based on typical experience, not guarantees for any individual case.
