Frequently asked questions

How long does N-400 citizenship take in 2026?+
N-400 processing in 2026 takes 8-24 months from filing to oath ceremony. The interview typically occurs 6-18 months after filing. The oath ceremony usually happens 1-4 months after the interview.
When can I apply for citizenship?+
Most green card holders can apply 90 days before their 5-year anniversary (3 years if married to a US citizen). You must have been physically present in the US for at least half the required period.
What is the N-400 interview like?+
The officer reviews your application, tests your English (reading/writing), asks civics questions (you must answer 6 of 10 correctly), and verifies your background. The interview typically takes 20-45 minutes.
What happens if I fail the civics test?+
You get a second chance at a follow-up appointment, typically within 60-90 days. If you fail again, USCIS will deny the application and you can refile.
Can I travel while N-400 is pending?+
Yes, with your green card. However, extended absences abroad can affect your continuous residence requirement. Keep trips under 6 months, and total absences under 30 months during the 5-year period.
