What is a potential reason for being called back for a second interview?

Being called back for a second interview is often due to the need to gather more information or clarify inconsistencies in the initial interview. During the first interview, the officer may identify discrepancies in the applicant's answers, the submitted documentation, or even between the accounts of the applicant and their spouse. This follow-up is crucial because the USCIS aims to ensure that all aspects of the application are accurate and truthful, especially in cases concerning marriage-based applications where the legitimacy of the relationship can be scrutinized.

In this context, the officer might have specific questions or additional details that need confirmation, which could have arisen during the review of the application or additional background checks. This ensures that all relevant information is thoroughly understood before making a decision on the application. Therefore, the emphasis on gathering more information is essential, as it directly impacts the outcome of the naturalization process.
