USCIS N-400
Complete Citizenship in Delaware
Most Form N-400 returns from USCIS are not about the merits of the case — they are about formatting, signatures, missing pages, and outdated editions. We treat each Delaware packet like an audit — assuming USCIS will look closely at every page — because that is the safer way to file. Years of preparing immigration packets in Central Ohio have taught us which supporting documents USCIS officers reach for first.

Form N-400 for Delaware Residents
Delaware permanent residents applying for U.S. citizenship through N-400 are scheduled for their naturalization interview at the USCIS Columbus Field Office (covering Delaware 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 Delaware applicants throughout Delaware County, including families connected to Delaware City Schools and workers around OhioHealth Grady Memorial Hospital. 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.
Our Delaware clients commonly include families served by Delaware City Schools and workers and patients tied to OhioHealth Grady Memorial Hospital.
Delaware · Central Ohio
Why this Form N-400 page is written for Delaware
Delaware sits in Central Ohio, small-town main streets, county-seat government employers, and increasingly residential growth from Columbus-area buyers seeking lower cost of living. Delaware County, where Delaware is located, is a sizable Ohio city where most county-level vital records and document services are available locally.
In Central Ohio, the most common immigration paperwork we prepare ties to family unity — bringing spouses, parents, and children through the right form sequence in the right order. For Delaware residents, we organize the packet so identity records, USCIS forms, civil documents, translations, and supporting evidence all match before anything is mailed.
a smaller-town demographic with growing immigrant families who have moved out from Columbus for school district choices and housing — and Delaware, with a population near 41,302, reflects that mix in its schools, workplaces, and houses of worship.
easy state-route access into Columbus — typically a single-highway drive with no transfers needed. From Delaware (ZIP 43015), the trip is roughly 22 miles each way.
At 22 miles (~32 min drive), Delaware is close enough that most clients can return for original-document pickup if needed, but we structure the work to avoid that whenever possible. We also serve families across the rest of Central Ohio, where many of our Delaware clients have relatives, coworkers, and shared community ties.

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?+
Columbus, Ohio naturalization interviews are conducted at the USCIS Columbus Field Office located at 4720 Polaris Pkwy, Westerville, OH 43082. The oath ceremony is also held at or near this location. Asal Multi Services prepares all Columbus-area clients specifically for the Columbus field office interview process.
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.
