US Citizenship (N-400) 요건 2026

Q: How much does it cost to apply for US citizenship?

The N-400 application fee is $710 USD when filing online via myUSCIS, or $760 if filing on paper. Biometrics are INCLUDED in the fee — there is no separate $85 biometrics charge for N-400 since the April 2024 USCIS fee rule. A reduced fee of $380 is available for income between 150%–400% of the federal poverty guideline (requested directly in Part 10 of the current N-400). Below 150%, request a full waiver via Form I-912.

Q: How long does the N-400 process take?

Median processing is currently about 6 months nationally, with 80% of cases finishing in 6 to 10.5 months. Field-office variance is significant — some offices complete in under 3 months, others take 13+ months. Check egov.uscis.gov/processing-times for your specific field office before you plan around the timeline.

Q: How long do I need to be a green card holder to apply for citizenship?

5 years of continuous residence as a lawful permanent resident, with at least 30 months of physical presence in the US during that period. The waiting period shortens to 3 years if you are married to and living with a US citizen who has been a citizen for the full 3 years.

Q: Do I need to speak English to become a US citizen?

Yes — you must demonstrate basic English reading, writing, and speaking ability at the interview, plus pass a civics test on US history and government. Exemptions exist for applicants 50+ with 20+ years of LPR status (50/20 rule) or 55+ with 15+ years (55/15 rule), who may take the civics test in their native language with an interpreter.

Q: What is the US civics test for citizenship?

For applications filed on or after October 20, 2025, USCIS uses the 2025 Naturalization Civics Test: a 128-question study bank, the officer asks up to 20 questions, and you must answer 12 correctly to pass (or fail after 9 incorrect). Applications filed before October 20, 2025 use the older 2008 test (10 questions from 100, pass with 6). Study materials at uscis.gov/citizenship.

Q: Can I keep my original citizenship after becoming a US citizen?

The US permits dual citizenship and does not require you to renounce your other nationality. However, your country of origin may have its own rules — some countries automatically revoke citizenship when you naturalize elsewhere. Check your home country's rules before the oath ceremony.

Lawful permanent residents (green card holders) who have held LPR status for at least 5 years (3 years if married to a US citizen) and meet residency, physical presence, English-language, civics, and good-moral-character requirements.
