Travel history, including extended trips
You can record every trip of 24 hours or more, including extended trips abroad. Enter your departure and return dates, and MimiDocu calculates how many days each trip lasted and highlights trips of 6 months or more for your review. If you have more trips than the form's travel table holds, the extra trips continue on the form's additional-information pages.
MimiDocu helps you prepare your travel information. It does not decide how your travel affects your eligibility.
Available languages
Questions and guidance in English, Spanish, and Arabic. USCIS requires the form itself to be completed in English, so your filled form is prepared in English.
How to submit your completed application
You download your completed official Form N-400 PDF, review every answer, then sign it and mail it to USCIS with the filing fee and supporting documents.
If you prefer to file online, you can use your prepared answers as a reference while entering them in your own USCIS online account. The PDF cannot be uploaded as an online application.
MimiDocu does not submit applications to USCIS and does not file on your behalf.
