N-400 — Naturalization immigration lawyers
About the N-400 category
Form N-400 is the application for naturalization — the process by which a lawful permanent resident becomes a U.S. citizen. Eligibility generally depends on holding a green card for the required number of years, meeting continuous-residence and physical-presence requirements, demonstrating good moral character, and passing English and U.S. civics tests, with some exceptions and accommodations available. USCIS conducts a biometrics appointment and an interview, and the case concludes with the oath of allegiance. Naturalization rewards careful preparation: long trips abroad, tax issues, an old arrest, or even an unnoticed problem in the original green-card case can surface at the interview, so a thorough eligibility review before filing is genuinely worthwhile.
Who the N-400 category is for
- You are a permanent resident meeting the residence and physical-presence rules.
- You show good moral character and pass the English and civics tests.
- Some applicants qualify for exceptions or accommodations.
How the process works
How a naturalization case unfolds: a lawful permanent resident confirms eligibility — the required years of residence, physical presence in the U.S., continuous residence, good moral character, and the English and civics requirements — and files Form N-400. USCIS schedules a biometrics appointment and then an interview, at which an officer reviews the application, tests English and civics, and examines the applicant's full immigration and personal history. If everything is in order, the case ends with the oath of allegiance. N-600 cases proceed by documentary review of the parent's citizenship and the applicant's qualifying relationship.
Common N-400 pitfalls
A handful of avoidable problems account for most setbacks in these cases — nearly all of them easier to fix before filing than after:
- Applying before the residence and presence math is met.
- Unresolved tax issues or undisclosed arrests.
- Long absences that break continuous residence.

How an immigration lawyer helps with a N-400 case
A naturalization lawyer reviews your eligibility before you file — the residence and physical-presence math, tax filings, and any arrests or past immigration issues — so a treatable problem does not turn into a denial or, in the worst case, a referral to removal. They also prepare you for the interview and the English and civics tests.
Choosing the right immigration lawyer
Not every immigration lawyer is the right fit for every case. The strongest signal is relevant, repeated experience with N-400 cases, followed by clear communication, responsiveness, and pricing you understand before you start. Use the profiles above to compare each attorney's background, the languages they speak, where they are based and what past clients say. Reading reviews and comparing a few practices side by side takes a little time, but it is far cheaper than discovering a mismatch halfway through a case.
What to expect from a consultation
What does a consultation actually give you?
