Ontario, a major city in San Bernardino County with over 175,000 residents, is home to a significant and growing Arab American community — including families from Iraq, Syria, Egypt, and Lebanon. Ontario residents complete their naturalization interviews at the USCIS San Bernardino Field Office located at 655 W. Rialto Avenue, San Bernardino, CA 92410. SoCal Immigration Services has guided hundreds of Arab families throughout the Ontario area through every phase of the naturalization process, from N-400 filing through interview preparation and oath ceremony attendance.

Understanding the N-400 Naturalization Interview

The naturalization interview is a face-to-face examination conducted by a USCIS officer at a designated field office. Under INA Section 312 (8 U.S.C. 1423), every applicant for naturalization must demonstrate an understanding of the English language and knowledge of U.S. history and government — unless they qualify for an exemption or waiver.

The interview consists of three core components:

1. English Language Test: The officer evaluates your ability to read, write, and speak English during the natural course of the interview. You will read one sentence aloud, write one sentence dictated by the officer, and demonstrate speaking ability through your responses to questions.

2. Civics Test: The officer asks you up to 10 questions from the official list of 100 civics questions. You must answer at least 6 correctly to pass. Questions cover American government, history, and integrated civics.

3. N-400 Application Review: The officer places you under oath and reviews every question on your N-400 application. You must confirm or correct your answers, provide additional details where requested, and sign the application.

In fiscal year 2025, USCIS conducted over 900,000 naturalization interviews nationwide. The national pass rate for the civics test is approximately 91%, and the overall naturalization approval rate stands at 89.4%.

2026 Civics Test: What You Need to Know

The USCIS civics test evaluates your knowledge of American government structure, constitutional principles, and U.S. history. As of 2026, USCIS administers the standard civics test with 100 possible questions.

The officer selects 10 questions at random from the 100-question bank. You must answer 6 correctly. The test is oral — the officer reads each question aloud, and you respond verbally. There is no written civics component.

The 100 questions are divided into three subject areas:

Subject Area	Number of Questions	Key Topics
American Government	57 questions	Branches of government, Constitution, Bill of Rights, amendments, elected officials
American History	30 questions	Colonial period, independence, Civil War, civil rights, post-9/11 era
Integrated Civics	13 questions	Geography, symbols, holidays, national landmarks

English Language Requirements and Exemptions

INA Section 312(a) requires naturalization applicants to demonstrate the ability to read, write, and speak words in ordinary usage in the English language. USCIS tests this through three components during the interview:

Reading Test: You must read one out of three sentences correctly. The sentences use vocabulary from the USCIS reading vocabulary list, which contains approximately 100 civics-related words.

Writing Test: You must write one out of three sentences correctly. The officer dictates a sentence, and you write it. Minor spelling or grammatical errors are acceptable if the meaning is clear.

Speaking Test: The officer evaluates your English-speaking ability throughout the interview based on your responses to questions about your N-400 application.

Congress established two important exemptions under INA Section 312(b):

50/20 Exemption: If you are 50 years old or older and have held your green card for at least 20 years, you are exempt from the English language requirement. You take the civics test in your native language through a USCIS-approved interpreter.

55/15 Exemption: If you are 55 years old or older and have held your green card for at least 15 years, you qualify for the same English exemption.

65/20 Special Consideration: If you are 65 years old or older and have held your green card for at least 20 years, you take a simplified version of the civics test — the officer selects from a designated subset of 20 questions instead of the full 100.

•Reading test: read one sentence correctly out of three attempts using USCIS reading vocabulary
•Writing test: write one dictated sentence correctly out of three attempts
•Speaking test: evaluated continuously during the interview based on your oral responses
•50/20 exemption: age 50+ with 20+ years as a permanent resident — civics test taken in native language
•55/15 exemption: age 55+ with 15+ years as a permanent resident — civics test taken in native language
•65/20 special consideration: age 65+ with 20+ years as a permanent resident — simplified 20-question civics test in native language

N-648 Medical Disability Waiver

If you have a physical or developmental disability or mental impairment that prevents you from demonstrating knowledge of English or civics, you qualify for a waiver under INA Section 312(b)(1). The N-648 Medical Certification for Disability Exceptions is the form your licensed medical professional must complete.

The N-648 waiver exempts you from both the English language requirement and the civics test requirement. It does not exempt you from other naturalization requirements such as good moral character, continuous residence, or physical presence.

Eligible conditions include but are not limited to: post-traumatic stress disorder (PTSD), traumatic brain injury, intellectual disabilities, severe depression, dementia, Alzheimer's disease, stroke-related cognitive impairment, and developmental disabilities.

Your medical professional must certify on the N-648 that your disability is expected to last 12 months or more, that the disability directly prevents you from learning or demonstrating English or civics knowledge, and that the disability is not caused by the illegal use of drugs.

Critical requirements for the N-648 filing:

•The N-648 must be completed by a licensed medical doctor (MD), doctor of osteopathy (DO), or licensed clinical psychologist
•The medical professional must have examined you within the last six months before filing
•The form requires a detailed clinical diagnosis with ICD-10 diagnostic codes
•The doctor must explain the specific connection between your disability and your inability to learn English or civics
•USCIS adjudicators scrutinize N-648 forms carefully — incomplete or vague forms are routinely denied
•You must still attend the naturalization interview in person, even with an approved N-648
•There is no filing fee for the N-648 itself — it is submitted as a supplement to your N-400 application

What to Bring to Your Naturalization Interview

Arriving fully prepared prevents delays and demonstrates to the USCIS officer that you take the process seriously. The following documents are required or strongly recommended for your interview at the San Bernardino Field Office:

•Interview appointment notice (Form N-445 or appointment letter from USCIS)
•Permanent resident card (green card) — original, not a copy
•Valid, unexpired passport or travel document
•State-issued photo ID (California driver's license or state ID)
•Two passport-style photographs (2x2 inches) in case USCIS requires updated photos
•Completed N-400 application — bring your personal copy for reference during the review
•All documents referenced in your N-400: marriage certificates, divorce decrees, court records, tax returns for the past 5 years (or 3 years if applying under INA 319(a) marriage to U.S. citizen)
•Evidence of Selective Service registration (for male applicants ages 18-31)
•Tax transcripts (IRS Form 1722) or copies of filed returns for the statutory period
•Any travel records, including passport stamps and I-94 records documenting trips outside the U.S.
•If applicable: N-648 Medical Certification, court disposition records for any arrests, child support documentation

Common Reasons for Naturalization Denial

Understanding the most frequent grounds for denial allows you to address potential issues before your interview. USCIS denied approximately 10.6% of N-400 applications in fiscal year 2025. The leading denial reasons for Ontario-area applicants include:

Failure to Pass English or Civics Test: If you fail either test, USCIS schedules a re-examination within 60 to 90 days. You receive one re-test opportunity. If you fail the re-examination, USCIS denies the application, and you must refile Form N-400 with a new $760 filing fee.

Good Moral Character Issues: USCIS examines the statutory period — typically 5 years (or 3 years under INA 319(a)) — for conduct that bars a finding of good moral character. Permanent bars include murder and aggravated felony convictions. Conditional bars include crimes involving moral turpitude (CIMT), drug offenses, multiple criminal convictions with aggregate sentences of 5+ years, and immigration fraud under INA 212(a)(6)(C).

Insufficient Physical Presence or Continuous Residence: Under INA 316(a), you must have been physically present in the U.S. for at least 30 months out of the 5-year statutory period. Any single trip outside the U.S. lasting 6 months or more creates a presumption of broken continuous residence under INA 316(b). Trips exceeding one year automatically break continuous residence.

Application Errors: Incomplete or inconsistent answers on the N-400 raise red flags. Discrepancies between your application and USCIS records, unreported arrests, or undisclosed foreign travel lead to denials or continued cases.

•Failing the English or civics test on both attempts results in denial — you must refile with a new $760 fee
•Criminal convictions, even minor ones, require court disposition records and may trigger good moral character analysis
•Trips outside the U.S. longer than 6 months presumptively break continuous residence
•Failing to file tax returns during the statutory period is treated as a negative factor for good moral character
•Providing false testimony under oath during the interview is a permanent bar to naturalization under INA 101(f)(6)
•Outstanding deportation or removal orders make you ineligible for naturalization

Same-Day Oath Ceremonies in Ontario

Same-day oath ceremonies allow approved applicants to take the Oath of Allegiance and become U.S. citizens on the same day as their naturalization interview. The USCIS San Bernardino Field Office conducts administrative oath ceremonies for eligible applicants who pass their interview.

Not every applicant qualifies for a same-day ceremony. USCIS grants same-day oaths when:

1. The officer approves your application during or immediately after the interview
2. An administrative ceremony is scheduled for that day at the field office
3. You are not requesting a legal name change (name changes require a judicial ceremony before a judge)
4. There are no outstanding background check or security clearance issues

If you do not receive a same-day ceremony, USCIS mails you a Form N-445 (Notice of Naturalization Oath Ceremony) scheduling your ceremony within 2 to 6 weeks. Judicial ceremonies in the San Bernardino area are held at the U.S. District Court for the Central District of California.

At the oath ceremony, you will:

1. Check in and submit your completed Form N-445 questionnaire
2. Surrender your permanent resident card (green card)
3. Stand and recite the Oath of Allegiance to the United States
4. Receive your Certificate of Naturalization (Form N-550)

After the ceremony, apply for your U.S. passport immediately. You can submit your passport application at the ceremony venue if a passport acceptance facility is available, or visit any post office or passport acceptance facility. The standard passport fee is $165 for a book or $35 for a card, with expedited processing available for an additional $60.

•Same-day ceremonies are administrative ceremonies held at the USCIS field office immediately after interview approval
•Name change requests require a judicial ceremony before a federal or state judge — not available same-day at field offices
•If not offered same-day, expect to receive Form N-445 scheduling your ceremony within 2-6 weeks
•Verify every detail on your Certificate of Naturalization (N-550) before leaving the ceremony venue
•Apply for your U.S. passport and register to vote on the same day as your ceremony
•Update Social Security records within 2 weeks of naturalization at your local SSA office

Interview Day: Step-by-Step Process

Knowing exactly what happens on interview day eliminates anxiety and helps you perform your best at the San Bernardino Field Office.

1
Arrive Early
Arrive at the USCIS San Bernardino Field Office at least 30 minutes before your scheduled appointment. Bring all required documents. Pass through security screening and check in at the reception desk with your appointment notice.
2
Wait for Your Name to Be Called
After check-in, wait in the designated area until a USCIS officer calls your name. Wait times vary from 15 minutes to over an hour depending on the office schedule.
3
Oath and Identity Verification
The officer will ask you to raise your right hand and swear or affirm that you will tell the truth. The officer then verifies your identity by comparing your green card and photo ID to your physical appearance.
4
English Speaking Evaluation Begins
The officer evaluates your spoken English from the moment the interview starts. Answer all questions clearly and in complete sentences when possible. The entire interview is conducted in English unless you qualify for a language exemption.
5
N-400 Application Review
The officer reviews each section of your N-400 application, asking you to confirm or update your answers. Be honest about any changes since filing — including new travel, address changes, arrests, or changes in marital status.
6
English Reading and Writing Test
The officer administers the reading test (read one sentence aloud) and writing test (write one dictated sentence). You have up to three attempts for each. The vocabulary comes from the official USCIS study materials.
7
Civics Test
The officer asks up to 10 civics questions from the 100-question bank. You must answer 6 correctly. The test stops as soon as you reach 6 correct answers. If you answer 4 incorrectly before reaching 6 correct, you fail.
8
Decision and Next Steps
The officer informs you of the result: approved (may offer same-day oath), continued (additional evidence needed), or denied. If approved, the officer provides instructions for the oath ceremony.

FAQFrequently Asked Questions

Q:How long does the naturalization interview take?

A: The naturalization interview at the USCIS San Bernardino Field Office typically lasts 20 to 45 minutes. The duration depends on the complexity of your case, the number of questions the officer needs to clarify, and whether you qualify for a same-day oath ceremony. Applicants with criminal history, extensive travel, or N-648 waivers should expect longer interviews.

Q:What happens if I fail the civics test or English test?

A: USCIS schedules a re-examination within 60 to 90 days of your initial interview. You retake only the portion you failed — civics, English, or both. If you fail the re-examination, USCIS denies your N-400 application, and you must refile with a new $760 filing fee. There is no limit on how many times you can refile.

Q:Can I bring an interpreter to my naturalization interview?

A: You can bring a USCIS-approved interpreter only if you qualify for the 50/20 or 55/15 English language exemption. The interpreter must be fluent in both English and your native language. If you do not qualify for an exemption, you must complete the entire interview in English without interpreter assistance.

Q:Does USCIS check my criminal record during the interview?

A: Yes. USCIS runs a comprehensive background check before and during the naturalization process, including FBI fingerprint checks, name checks across multiple federal databases, and review of state and local criminal records. The officer will ask about every arrest, citation, or detention — even those that did not result in conviction. You must disclose all encounters with law enforcement on your N-400 and bring court disposition records.

Q:How do I qualify for the N-648 disability waiver for the civics and English tests?

A: You qualify for the N-648 waiver if you have a physical or developmental disability or mental impairment that has lasted or is expected to last at least 12 months and directly prevents you from learning or demonstrating knowledge of English or U.S. civics. A licensed medical doctor, doctor of osteopathy, or clinical psychologist must complete Form N-648 with a detailed clinical diagnosis, ICD-10 codes, and an explanation of how your condition prevents you from meeting the testing requirements. The N-648 is filed with your N-400 application at no additional cost.
