Dates that do not line up, trips abroad that need to be listed, missing signatures. The app flags them before you file, not after.

Permanent residents getting ready to apply for U.S. citizenship who want a clear, careful way to prepare Form N-400 themselves. If your situation is complicated, for example a criminal record, long absences from the country, or a prior denial, we recommend talking to an immigration attorney or an accredited representative before you file.
