Form N-400 for Baltimore Residents
Baltimore permanent residents applying for U.S. citizenship through N-400 are scheduled for their naturalization interview at the USCIS Columbus Field Office (covering Fairfield County and most of Central Ohio). We prepare your application packet, organize your tax transcripts and travel history, and walk you through the civics test questions ahead of your interview date.
Our office serves Baltimore applicants throughout Fairfield County, including families connected to Liberty Union-Thurston Local Schools. Clients often come to us after receiving a USCIS notice, preparing for a family petition, renewing documents for work, or trying to understand which records must be translated before filing.
Practical Filing Guide
What this Form N-400 page helps you understand
Form N-400 is the application for naturalization, the process of becoming a U.S. citizen.
Permanent residents usually file after meeting the required continuous residence, physical presence, and good moral character rules.
We spend extra time on travel history and address history because those sections often create interview questions.
We also prepare clients for what to expect at the Columbus naturalization interview.

Frequently Asked Questions
How long do I need to have a green card before applying for citizenship in Columbus, Ohio?+
Most green card holders must wait 5 years from the date of becoming a lawful permanent resident before applying for naturalization (N-400). If you have been married to and living with a U.S. citizen for the past 3 years, you can apply after 3 years of having a green card. You can file your N-400 up to 90 days early.
What is the civics test for naturalization?+
The USCIS civics test consists of 10 questions randomly selected from a list of 100 questions about U.S. history and government. You must answer 6 out of 10 correctly to pass. The test is given orally during your N-400 interview. If you fail, USCIS gives you one more chance to take the test at a second interview appointment. Asal Multi Services provides civics test study materials and practice sessions.
Where is the USCIS interview for Columbus, Ohio citizenship applications?+

What trips outside the U.S. could disqualify me from citizenship?+
Single trips abroad of 6 months or more can break "continuous residence" and disrupt your eligibility clock. Trips of 1 year or more create a presumption that you abandoned your residence. If you have made long trips outside the U.S., do not assume you are ineligible — many exceptions apply. Asal Multi Services reviews your travel history and advises you before you file.
