Name a common form of proof that shows you and your spouse live together.

A joint lease or mortgage document is a strong form of proof that demonstrates you and your spouse live together because these documents are legally binding agreements that typically include both names, indicating shared responsibility for the property. This evidence is crucial during the marriage interview for naturalization, as it clearly illustrates your living arrangement and commitment to each other in a shared environment.

While joint bank statements and utility bills can also provide evidence of cohabitation, they may not be as definitive as a joint lease or mortgage. For instance, joint bank statements might not explicitly show that you are living together, as they could represent shared finances that do not necessarily correlate with residency. Utility bills can support the case for cohabitation but might not include both names, especially if one spouse's name is solely on the account.

Travel itineraries can demonstrate that you travel together, but they do not establish living arrangements, so they serve a different purpose in proving a genuine marriage. The joint lease or mortgage stands out as the most direct evidence of shared residence.
