What does documentation refer to?

Documentation refers to records that provide evidence or support for the truth of something. In the context of the USCIS N-400 application, documentation is crucial as it substantiates the claims made by the applicants regarding their identity, residency, and eligibility for naturalization. This might include documents like birth certificates, marriage licenses, tax returns, and other legal papers that help demonstrate the information the applicant provides on their application. Proper documentation is essential for verifying an applicant’s eligibility and ensuring the integrity of the naturalization process.

The other options relate to different concepts: legal requirements for military service and actions taken during military service deal specifically with military obligations, while promises made to the government pertain to commitments or oaths rather than verifiable evidence. Thus, they do not accurately represent the meaning of documentation in the context of the N-400 application.
