What is your spouse's phone number?

The rationale behind choosing both phone numbers as the correct answer lies in the understanding that the question requires knowledge of the spouse's phone number. In many cases, individuals may have more than one phone number associated with their spouse, such as a mobile phone and a home phone. By selecting both options, it acknowledges that either number could potentially be correct, depending on the context and personal circumstances.

In the context of a marriage interview for naturalization, it is not uncommon for applicants to be aware of more than one contact number for their spouse. Therefore, the choice of both reflects a more comprehensive understanding of the relationship and communication patterns. This nuance in marital awareness is critical during the interview, as it demonstrates the depth of knowledge one might have about their spouse.

For those unfamiliar with the requirements of the interview, it’s important to recognize that providing accurate and detailed information about one's spouse can significantly impact the assessment of the marriage’s legitimacy.
