What outcome follows a successful interview of the N-400?

Following a successful interview of the N-400, the applicant is granted a Naturalization Certificate after meeting all the requirements for citizenship. This certificate serves as formal proof of the applicant's status as a naturalized citizen, confirming their new rights and responsibilities.

If the application is successful during the interview process, it typically leads to a ceremony where the applicant takes an oath of allegiance, and afterward, they receive the Naturalization Certificate. This document is essential as it not only signifies citizenship status but also allows the individual to apply for a U.S. passport, vote, and enjoy other benefits that come with being a U.S. citizen.

In contrast, the other options involve scenarios that either indicate a delay in the process—like needing to provide more documents or undergoing further investigation—or suggest immediate citizenship, which is not how the process works. The Naturalization Certificate is a key component that signals the completion of the citizenship journey, making it the correct choice.
