To prove a bona fide marriage for immigration purposes in the United States, couples must provide various supporting documents demonstrating the authenticity of their relationship. Examples of these documents include a marriage certificate, joint financial documents, property ownership records, insurance policies, utility bills, correspondence, travel records, photographs, affidavits from friends and family, birth certificates of children, shared memberships, and social media posts. The more documentation and variety of evidence a couple can provide, the stronger their case will be when reviewed by immigration officers. Tailor the supporting documents to your unique situation.
