Filing Form N-400 is not simply about completing a government form. You are presenting your immigration history, travel, residence, employment, family history, taxes, criminal history, and eligibility for U.S. citizenship to USCIS—and seemingly small mistakes or inconsistencies can create delays, Requests for Evidence, complications, or denial.

N-400 Citizenship Filing Kit – Attorney Edition is a comprehensive, attorney-built system designed to help you prepare, review, and present your own naturalization case from beginning to end.

Written from the perspective of an experienced immigration attorney, this Filing Kit explains not only what to do, but why it matters, what USCIS is evaluating, where applicants commonly run into problems, and how to identify weaknesses before filing.

Inside, you will learn how to:

• Determine whether Form N-400 is actually the correct path to citizenship for you.
• Evaluate the five-year and three-year naturalization routes and other eligibility considerations.
• Understand continuous residence, physical presence, international travel, and the 90-day early-filing rule.
• Choose between filing your N-400 online or by mail and correctly prepare either type of submission.
• Work through the critical N-400 questions and identify answers that require additional attention.
• Review names, addresses, employment, marriage, travel, tax, criminal, Selective Service, and prior immigration history for inconsistencies.
• Understand why “Have you ever” questions require particularly careful review.
• Prepare and organize the documents and evidence appropriate to your case.
• Avoid common mistakes that can cause rejection, delays, RFEs, or problems at interview.
• Understand what happens after filing, including receipt notices, biometrics, case processing, and USCIS requests.
• Prepare for the naturalization interview, English test, and civics test.
• Practice with 50 attorney-created interview and civics questions.
• Conduct a detailed final N-400 case audit before filing and again before your interview.
• Use practical templates, worksheets, checklists, and preparation tools to organize your case.

Throughout the Filing Kit, Attorney Tips and real-case insights explain the issues that frequently matter in actual immigration practice—including situations where having a green card does not necessarily mean that applying for naturalization is risk-free.

This is not a bare checklist and it is not a reproduction of government instructions. It is designed to teach you how to think through your naturalization case as a complete case: eligibility, evidence, consistency, risk, preparation, filing, interview, and final approval.

If you are preparing to apply for U.S. citizenship through Form N-400 and want a structured, attorney-developed roadmap rather than trying to piece together your case from scattered information, this Filing Kit gives you the framework to prepare your application carefully and confidently.
