What Is Oath of Allegiance
The Oath of Allegiance is the formal pledge you take during a naturalization ceremony to renounce allegiance to your previous country and swear loyalty to the United States. It is the final step that officially makes you a U.S. citizen. USCIS administers this oath at naturalization ceremonies held throughout the country, typically after your N-400 Application for Naturalization is approved and you pass the civics and English language tests.
The Oath Text
The statutory oath, codified in 8 U.S.C. Section 1448, reads: "I hereby declare, on oath, that I absolutely and entirely renounce and abjure all allegiance and fidelity to any foreign prince, potentate, state, or sovereignty of whom or which I have heretofore been a subject or citizen; that I will support and defend the Constitution and laws of the United States of America against all enemies, foreign and domestic; that I will bear true faith and allegiance to the same; that I will bear arms on behalf of the United States when required by law; that I will perform noncombatant service in the Armed Forces when required by law; and that I take this obligation freely without any mental reservation or purpose of evasion; so help me God."
You can request a modified oath if you have religious objections to the combat and military service portions. USCIS approves these accommodations routinely for applicants with pacifist beliefs.
Timing in Your Immigration Timeline
The oath comes after you have been a lawful permanent resident (green card holder) for a required period. For most immigrants, this is 5 years of green card status. If you are married to a U.S. citizen, the requirement drops to 3 years. Immediate relatives of deceased U.S. citizens have additional eligibility pathways under INA 319.
You cannot take the oath until USCIS formally approves your N-400 application. The approval notice will specify the date, time, and location of your oath ceremony. Missing this appointment typically results in denial of your naturalization application unless USCIS grants a reschedule.
What Happens at the Ceremony
- You must bring your green card, state ID or passport, and the oath ceremony notice USCIS mailed to you
- USCIS officer confirms your identity and verifies you still meet eligibility requirements
- You take the oath in English in front of a USCIS officer or federal judge
- You receive your Certificate of Naturalization, which is your proof of U.S. citizenship
- You can apply for a U.S. passport immediately after receiving your certificate
What Changes After the Oath
Taking the oath triggers several immediate changes. You become a U.S. citizen and lose your previous citizenship status (though some countries allow dual citizenship). You can no longer be removed from the United States through deportation. You gain the right to vote, serve on juries, and hold most federal jobs. You can sponsor family members for green cards with shorter processing times under immediate relative categories.
Common Questions
- Can I reschedule my oath ceremony? Yes, contact your local USCIS office before the scheduled date and request a reschedule. Expect to wait 30 to 60 days for a new date. Failing to show without requesting a reschedule will result in denial of your N-400.
- What if I am traveling when my oath ceremony is scheduled? Inform USCIS in writing at least two weeks before your ceremony. Do not assume you can reschedule after missing the date, as USCIS denials are common in these situations.
- Do I need a lawyer to take the oath? No. The oath ceremony is administrative and does not require legal representation. However, having an immigration attorney review your N-400 application before you file significantly reduces the chance of denial.
