What occurs during an immigration marriage interview?

At a marriage interview related to immigration matters, an immigration officer will assess whether a couple is genuinely in a legitimate relationship, not merely legally married on paper. The officer verifies if the couple truly resides together in good faith. Various forms of evidence are submitted, such as shared tax returns, joint bills, bank statements, insurance documents, and more. Additionally, photographs and evidence of joint vacations are presented to convince a stranger, within a relatively short timeframe, that the marriage is based on genuine love and that the couple shares a real domestic life together.
