Naturalization is the final chapter of an immigration journey that often spans years, sometimes decades. For green card holders in Goose Creek, Summerville, Moncks Corner, and the Charleston, SC area who are ready to become U.S. citizens, the N-400 process is largely predictable. It rewards careful preparation and punishes shortcuts.
This checklist walks through the major requirements and pitfalls, in the order they tend to come up in our consultations.
Eligibility: Are You Ready to File?
Most applicants must have held a green card for at least five years (three years if married to and living with a U.S. citizen the entire time). You must have been physically present in the U.S. for at least half of that period and continuously resident, meaning no single trip abroad longer than six months without strong justification.
You also must be a person of good moral character during the statutory period, demonstrate basic English ability, pass the civics test, and take the oath of allegiance.
Documents to Gather Before You File
Pull together the following before opening the N-400: your green card (front and back), your most recent passport(s) covering the statutory period, complete travel history with dates, tax transcripts for the past 3–5 years, marriage and divorce certificates for every marriage, certified court dispositions for any arrest in your history, and Selective Service registration confirmation (for males who were 18–25 as LPRs).
If your name has changed since you became an LPR, gather every supporting document. If you've lived at multiple addresses, list them all with exact dates.
The Interview and Civics Test
Charleston-area N-400 applicants interview at the Charleston Field Office. The interview is a conversation: the officer reviews your application line by line, then administers the English and civics tests.
The civics test is currently 10 questions drawn from a study list of 100. You need 6 correct to pass. The English test covers basic reading, writing, and speaking. Free study materials are available on the USCIS website, use them, and use them out loud.
Common Red Flags
Long trips abroad, unpaid taxes, child support arrears, undisclosed arrests, and prior misrepresentations on immigration applications are the most common reasons N-400s get denied, or, worse, referred for removal proceedings. None of these are automatic disqualifiers, but each requires careful handling and, often, an attorney's help before filing.
