Becoming a U.S. Citizen
Naturalization is the process by which a lawful permanent resident (green card holder) becomes a U.S. citizen. It is one of the most important steps an immigrant can take. U.S. citizenship provides permanent security — unlike a green card, it cannot be taken away. This section explains who qualifies, what the process looks like, and what to expect.

🎖️ Expedited Military Path
Members of the U.S. Armed Forces have special rules that can allow faster naturalization — sometimes with no waiting period. Contact your military unit's legal assistance office for details.
⚠️ What Can Prevent Naturalization
Criminal bars:
- ✗ Conviction for murder at any time — permanent bar
- ✗ Conviction for an aggravated felony after November 29, 1990 — permanent bar
- ✗ Conviction for certain crimes within 5 years of applying (or 3 years for the married path)
- ✗ Multiple criminal convictions with combined sentences of 5+ years
- ✗ Drug-related convictions (some exceptions apply)
- ✗ DUI or DWI convictions (may not be an absolute bar but are carefully reviewed)
Other bars:
- ⚠ Lying on the naturalization application (misrepresentation)
- ⚠ Failing to pay taxes (must be current on all tax obligations)
- ⚠ Not registering for Selective Service if you were a male between ages 18–25 (affects some applicants)
- ⚠ Being a member of or supporting certain prohibited organizations (e.g., Communist Party, terrorist organizations)
- ⚠ Desertion from the U.S. military
- ⚠ Avoiding military service by claiming to be a non-citizen when you were required to register
Having a criminal record does NOT automatically bar you from naturalization. The type of crime, when it happened, and whether it was a federal or state offense all matter. Consult an immigration lawyer before applying if you have ANY criminal history.
📝 The Civics Test
The civics test covers U.S. history and government. There are 100 official questions. During your interview, the USCIS officer will ask you up to 10 of those questions. You must answer at least 6 out of 10 correctly to pass.
Study resources:
- → All 100 questions and answers are published free at uscis.gov/citizenship/find-study-materials-and-resources
- → USCIS publishes free study materials in multiple languages
- → Practice tests are available online and on mobile apps
Exemptions:
- ✓ Age 50+ AND green card holder for 20+ years: can take the test in your native language (no English test required for the civics test)
- ✓ Age 55+ AND green card holder for 15+ years: same language exemption
- ✓ Age 65+ AND green card holder for 20+ years: only need to know 20 of the 100 civics questions (flagged with an asterisk on the USCIS list)
- ✓ Disability exemption: if you have a physical or developmental disability or mental impairment, you may request an exemption from the English and/or civics test using Form N-648
Sample questions:
- What is the supreme law of the land? (The Constitution)

- Who is the Commander in Chief of the military? (The President)

🗣️ The English Test
The English test during the N-400 interview has three parts: • Reading: You must read 1 of 3 sentences out loud in English correctly. • Writing: You must write 1 of 3 sentences in English correctly. • Speaking: The officer evaluates your ability to understand and answer questions during the interview. The interview itself IS the speaking test.
Exemptions:

- ✓ Age 55+ with 15 years as LPR: same exemption
- ✓ Disability: Form N-648 can exempt you
- 💡 Practice speaking English every day — even having simple conversations helps.
- 💡 Practice reading news headlines and short paragraphs out loud.
- 💡 Practice writing sentences by hand — USCIS tests handwriting, not typing.

Attend the Oath of Allegiance Ceremony
After approval, you are scheduled for a naturalization ceremony where you take the Oath of Allegiance to the United States. You are officially a U.S. citizen the moment you take the oath. At the ceremony: • You will receive your Naturalization Certificate (Certificate of Naturalization) — keep this document safe forever. • You will surrender your green card. • You can apply for a U.S. passport the same day if you bring the right documents to the ceremony location. Some ceremonies are at a courthouse with a judge. Others are administrative ceremonies held by USCIS directly.
