For many immigrants, applying for U.S. citizenship is one of the biggest and most meaningful steps they’ll ever take. It marks the end of years of paperwork, waiting, and uncertainty—and the start of full participation in American life. But getting there involves a few specific requirements and a process that can take several months or longer.
At Tourzani & Long, LLC, we’ve helped countless clients through this journey. Some came to us with doubts about eligibility, others just needed guidance getting through the final steps. Wherever you’re starting from, here’s a straightforward look at the requirements for naturalization—and what kind of timeline you can expect.
Who Can Apply for U.S. Citizenship?
Most applicants qualify for naturalization through one of the following categories:
- You’ve had a green card for at least 5 years
- You’ve had a green card for at least 3 years and are married to a U.S. citizen
- You’ve served in the U.S. military under qualifying conditions
- You’re the child of a U.S. citizen and meet specific age and residency criteria
Beyond your category, you’ll also need to meet general requirements:
- Be at least 18 years old
- Have continuous residence in the U.S. for the required period
- Have spent at least half of that time physically in the U.S.
- Be a person of good moral character
- Be able to read, write, and speak basic English (with some exceptions)
- Pass a civics test on U.S. history and government
- File taxes and stay current on any financial obligations
Certain applicants—especially older adults or those with disabilities—may qualify for exemptions from the English and civics test requirements. We help people figure that out all the time.
What Documents and Information Do You Need?
The core of the application is Form N-400, but USCIS also expects you to provide:
- A copy of your green card
- Any documentation related to marriage, divorce, or legal name changes
- Records of criminal history or prior arrests (even if charges were dropped)
- Information about trips abroad, past immigration applications, and employment history
- Payment of the filing fee (or a request for a fee waiver, if eligible)
If you’re applying based on marriage to a U.S. citizen, you’ll also need to include documents that show your relationship is real—things like joint tax returns, lease agreements, or photos together.
The Naturalization Timeline: What to Expect
The full process usually takes 8 to 14 months, but that can vary based on your location and specific case. Here’s a general breakdown of the timeline:
- Filing the N-400
Once you submit your application and fee, USCIS will issue a receipt notice confirming they’ve accepted it. - Biometrics Appointment (3–6 weeks later)
You’ll be scheduled for a short appointment where USCIS takes your fingerprints, photo, and signature for a background check. - Interview and Civics Test (4–10 months after filing)
You’ll meet with a USCIS officer to review your application and take the naturalization test. You’ll be asked questions about your history and answer up to 10 civics questions (you need 6 correct to pass). - Decision
If all goes well, USCIS may approve your application the same day as your interview—or shortly after. If they need more information or documents, you’ll receive a Request for Evidence (RFE) or be scheduled for a second interview. - Oath Ceremony (within a few weeks of approval)
You’ll take the Oath of Allegiance, turn in your green card, and receive your Certificate of Naturalization—officially becoming a U.S. citizen.
Things That Can Affect the Timeline
While many cases move smoothly, a few factors can slow things down:
- Long or frequent trips outside the U.S.
- Criminal history or unresolved legal issues
- Mistakes on the application or missing documents
- Name discrepancies or identity concerns
- Backlogs at your local USCIS field office
We’ve helped people resolve each of these issues—sometimes it’s just a matter of submitting a clarification, other times it requires legal arguments or preparing for a follow-up interview.
